The fan module of an air conditioning outdoor unit includes a wind turbine, a wind guiding ring, a motor, a motor bracket, and the like, and when designing the air conditioning outdoor unit, it is often required to maintain low operating noise and a high aerodynamic efficiency while ensuring to provide a high air volume. An electronic control box is often arranged at one side of the inside of the air conditioning outdoor unit, however, since the electronic control box is located at the air inlet of the wind turbine or at the air inlet channel of the wind turbine, the electronic control box blocks a part of the air inlet channel, resulting in a decrease in the air output of the air conditioning outdoor unit. At the same time, the presence of the electronic control box interferes with the otherwise uniform airflow of the wind turbine and the turbulent airflow creates additional aerodynamic noise.

It is to be understood that the terminology used herein is to describe specific example embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an”, and “the” are intended to include the plural forms as well, unless the context indicates otherwise. The terms “include/comprise”, “contain”, and “have” are inclusive and therefore specify the presence of stated features, elements, and/or components, but do not preclude the presence or addition of one or more other features, elements, components, and/or groups thereof.

Furthermore, the terms “first” and “second” are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly designating the number of features indicated. Thus, a feature defined as “first” and “second” may explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of “a plurality of” is at least two, for example, two, three, and the like unless explicitly specifically limited otherwise.

For example, the panel 101 may be detachably coupled to the box body 111, or the panel 101 may be rotatably coupled to the box body 111. An air outlet is provided at the top of the box body 111.

The number of panels 101 may be one or more. The heat exchanger 30 is provided inside the case 110, an air outlet is provided at the top of the case 110, a fan module 1000 is provided at the top of the case 110 at the position of the air outlet, and a mesh cover 103 is provided at the top of the case 110 at the air outlet side of the air outlet.

To reduce the influence of the electronic control box 20 on the gas field and noise around the wind turbine 10, the embodiment of the present application proposes the definition of the distance between the electronic control box 20 and the compressor 40 to provide a larger installation range for the installation height of the compressor 40 based on reducing the interference of the electronic control box 20 and the compressor 40 with each other during installation and maintenance, so that the axial distance between the electronic control box 20 and the wind turbine 10 can be indirectly adjusted by adjusting the distance between the electronic control box 20 and the bottom of the case 110, to improve the influence of the electronic control box 20 on the inlet flow field and inlet noise of the wind turbine 10.

On the premise of ensuring the normal operation and convenient maintenance of the air conditioning outdoor unit 100, by rationally arranging the distance between the electronic control box 20 and the wind turbine 10, the adverse effect of the electronic control box 20 on the air conditioning outdoor unit 100 is reduced, and the air volume loss and noise caused by the electronic control box 20 are reduced. The distance between the top of the electronic control box 20 to the bottom of the wind turbine 10 described in the embodiments of the present disclosure may be selected to be the minimum distance of the vertical distance between the top of the electronic control box 20 to the bottom of the wind turbine 10.

In one embodiment, by increasing the axial spacing between the electronic control box 20 and the wind turbine 10, the effect of the electronic control box 20 on the flow field at the air inlet of the wind turbine 10 can be reduced, and in the above distance range, especially in the optional range 0.14×D≤Z₁≤0.16×D, the effect of the electronic control box 20 on the wind turbine 10 is small, facilitating the generation of higher wind volumes and noise control. As shown in FIG. 7, when satisfied 0.1≤Z₁/D≤0.16, the ratio of the noise value to the air volume in the case 110 can be minimum, and in this case, the ratio of the noise value to the air volume in the case 110 is between 5.08 and 5.2, for example, but not limited to: when Z₁/D=0.1, the ratio of noise value to air volume is 5.2, when Z₁/D=0.12, the ratio of noise value to air volume is 5.12, when Z₁/D=0.13, the ratio of noise value to air volume is 5.09, when Z₁/D=0.14, the ratio of noise value to air volume is 5.07, and when Z₁/D=0.16, the ratio of noise value to air volume is 5.09.

Furthermore, the width dimension of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction can be selected as T≤0.1×D: the lower limit of the value range of T is determined according to the actual design requirements of the electronic control box 20; the presence of the electronic control box 20 blocks the air inlet of the wind turbine 10, and at the same time reducing the amount of air inlet, also causes the phenomenon of uneven air inlet of the wind turbine 10; and the embodiment of the present application is one of the effective methods for reducing the influence of the electronic control box 20 on the inlet flow field of the wind turbine 10 by reducing the width of the electronic control box 20.

In the present embodiment, the part of the electronic control box 20 is located at the middle connection part of the two wind guiding rings 13 of the two wind turbines 10, and the middle connection part of the two wind guiding rings 13 is not located at the air channel of the air conditioning outdoor unit 100. The embodiment of the present application proposes that the wind guiding rings 13 are provided on the air outlet side of each wind turbine 10, and at least part of the electronic control box 20 is located below the two adjacent wind guiding rings 13, which can reduce the shielding of the air channel at the inlet of the wind turbine 10 by the electronic control box 20, facilitating the improvement of the air volume and controlling the interference noise.

As shown in FIGS. 1, 4, 5, and 6, the present disclosure provides an air conditioning outdoor unit 100 including a case 110, a wind turbine 10, and an electronic control box 20, where the top of the case 110 is provided with an air outlet, the wind turbine 10 is arranged at the top of the case 110 and located at the air outlet, the electronic control box 20 is arranged at the case 110, and the width of the projection of the electronic control box 20 falling on the wind turbine 10 along a vertical direction is T, and T≤0.15×D, D being the diameter of the wind turbine 10.

For the air conditioning outdoor unit of the present disclosure, the embodiments of the present application propose to improve the airfield and noise inside the case 110 by adjusting the position of the electronic control box 20, and particularly, the present disclosure provides an outdoor unit for air conditioner 100 including a box body 111 and a panel 101. The box body 111 is opened with an opening (as shown in FIG. 1, the opening is located at the panel 101 on the right side of the case 110), and the panel 101 is movably connected to the opening to open or close the opening. For example, the panel 101 may be detachably coupled to the box body 111, or the panel 101 may be rotatably coupled to the box body 111. An air outlet is provided at the top of the box body 111.

The number of panels 101 may be one or more. A heat exchanger 30 is provided inside the case 110. An air outlet is provided at the top of the case 110. A fan module 1000 is provided at the position where the top of the case 110 is located at the air outlet, and a mesh cover 103 is provided at the air outlet side of the fan module 1000 at the top of the case 110.

It would be appreciated that both the heat exchanger 30 and the electronic control box 20 within the case 110 are located in the air flow path. The heat exchanger 30 serves to exchange heat with the air flow at the air duct, and the heat exchanger 30 is provided around the periphery of the case 110 with the air duct almost completely covering the inner space of the case 110. The electronic control box 20 is disposed in the inner space of the case 110, so that the electronic control box 20 blocks a part of the air path, resulting in a decrease in the air output of the air conditioning outdoor unit 100. At the same time, the presence of the electronic control box 20 interferes with the otherwise uniform airflow of the wind turbine 10, and the turbulent airflow of the wind turbine 10 creates additional aerodynamic noise.

In the case where the wind guiding ring 13 is provided on the air outlet side of the wind turbine 10, the wind guiding ring 13 is not located in the air channel of the wind turbine 10, and by limiting the width of the electronic control box 20, most of the electronic control box 20 can be located below the wind guiding ring 13, so that the shielding of the air channel and the inlet of the wind turbine 10 by the electronic control box 20 can be reduced, which is beneficial to the improvement of the air volume and the control of interference noise.

In some embodiments, as shown in FIGS. 1, 2, and 6, at least a portion of the electronic control box 20 is located inside the case 110.

A wind guiding ring 13 is provided between the wind turbine 10 and the case 110 of the air conditioning outdoor unit 100, and the width of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction in the embodiment of the present application includes the width of at least a part of the electronic control box 20 located inside the case 110 minus the thickness of the wind guiding ring 13, namely, in the case where the air outlet side of the wind turbine 10 is provided with the wind guiding ring 13, the electronic control box 20 is located below the wind guiding ring 13, and T=T1−T2; T1 is the width of the part of the electronic control box 20 located inside the case 110, and T2 is the thickness of the wind guiding ring 13.

In some embodiments, the width of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction is T≤0.1×D, and the lower limit of the value range of T is determined according to the actual design requirements of the electronic control box 20; the presence of the electronic control box 20 blocks the air inlet of the wind turbine 10, and at the same time reducing the amount of air inlet, also causes the phenomenon of uneven air inlet of the wind turbine 10; and the embodiment of the present application is one of the effective methods for reducing the influence of the electronic control box 20 on the inlet flow field of the wind turbine 10 by reducing the width of the electronic control box 20. As shown in FIG. 8, through experiments, in the case T/D≤0.15, the influence of the electronic control box 20 on the flow field and noise at the inlet of the wind turbine 10 is minimal, the noise at the inlet of the wind turbine 10 can be reduced below 61.58, for example, but not limited to the following five types: when T/D=0.1, the noise value is 61.4 dBA; when T/D=0.08, the noise value is 61.4 dBA; when T/D=0.06, the noise value is 61.3 dBA; when=0.04, the noise value is 61.2 dBA; and when T/D=0.02, the noise value is 61.1 dBA.

As shown in FIGS. 6, 11 and 12, the air conditioning outdoor unit includes a case 110, an air outlet is provided at the top of the case 110, at least two wind turbines 10 are arranged at the air outlet, an electronic control box 20 is arranged at the case 110 and crosses two adjacent wind turbines 10 and is located below the wind turbines 10, and the projected area of the electronic control box 20 on the wind turbines 10 in the vertical direction is S, then 0.5(2×S1+S2)≤S≤(2×S1+S2), where

$S 1 = R \cdot T \cdot \sin (a) - \frac{(A - \sin (a)) R^{\land} 2 + TR \sin (a)}{2},$

In the present embodiment, by defining the projected area S of the electronic control box 20 on the wind turbine 10 in the vertical direction, it is possible to directly define the shielding of the two air passages of the two wind turbines 10 by the electronic control box 20 at the same time, to achieve the purpose of reasonably controlling the overall ventilation effect of the air conditioning outdoor unit 100, reducing the phenomenon that the air outlet volume of one side of the air conditioning outdoor unit 100 is large and the air outlet volume of the other side is small, and achieving the effect that the two sides can uniformly outlet air.

Referring to FIG. 6, in some embodiments, the width of the projection of the electronic control box 20 onto at least two wind turbines 10 along a vertical direction is T, T≤0.15×D, and D is the diameter of the wind turbine 10.

The embodiment of the present application proposes to improve the airfield and noise inside the case 110 by adjusting the position of the electronic control box 20, specifically, in the case where the wind guiding ring 13 is provided on the air outlet side of the wind turbine 10, the wind guiding ring 13 is not located in the air channel of the wind turbine 10, and by limiting the projection width of the electronic control box 20, the majority of the electronic control box 20 can be located below the wind guiding ring 13, and the shielding of the air inlet and the air channel of the wind turbine 10 by the electronic control box 20 can be reduced, facilitating the improvement of the air volume and controlling the interference noise.

As shown in FIG. 12, in some embodiments, the air conditioning outdoor unit 100 may be provided with only one U-shaped heat exchanger and one U-shaped heat exchanger is provided around the inner wall of the case 110.

In some embodiments, the case 110 is a rectangular structure, the air outlet at the top of the case 110 is a rectangular structure or a circular structure, the electronic control box 20 is a rectangular structure, and the wind guiding ring 13 is of a circular structure. By arranging the electronic control box 20 inside the case 110, the electronic control box 20 can be located at the corner between the wind guiding ring 13 and the case 110, to minimize the interference of the electronic control box 20 on the air passage and improving the ventilation performance and noise reduction capability of the wind turbine 10.

As shown in FIG. 1, in some embodiments, the distance between the top of the electronic control box 20 and the bottom of the wind turbine 10 is Z₁, 0.1×D≤Z₁≤0.2×D, where D is the diameter of the wind turbine 10.

The air conditioning outdoor unit 100 of the present disclosure reduces the adverse effect of the electronic control box 20 on the air conditioning outdoor unit 100 and reduces the air volume loss and the noise caused by the electronic control box 20 by rationally arranging the distance between the electronic control box 20 and the wind turbine 10 on the premise of ensuring the normal operation and convenient maintenance of the air conditioning outdoor unit 100. The distance between the top of the electronic control box 20 to the bottom of the wind turbine 10 described in the embodiments of the present disclosure is the minimum distance of the vertical distance between the top of the electronic control box 20 to the bottom of the wind turbine 10.

In order to reduce the influence of the electronic control box 20 on the air field and noise around the wind turbine 10, the embodiment of the present application proposes that the air field and noise inside the case 110 can be improved by adjusting the position of the electronic control box 20, in particular, the distance Z₁between the top of the electronic control box 20 and the bottom of the wind turbine 10 and the diameter D of the wind turbine 10 can effectively improve the influence of the electronic control box 20 on the air volume and noise inside the case 110 under the satisfied conditions 0.1×D≤Z₁≤0.2×D. In particular, by increasing the axial spacing between the electronic control box 20 and the wind turbine 10 (in the height direction as shown in FIG. 2), the effect of the electronic control box 20 on the flow field at the inlet of the wind turbine 10 can be reduced, and within the above-mentioned distance range, in particular within the range 0.14×D≤Z₁≤0.16×D, the effect of the electronic control box 20 on the wind turbine 10 is small, facilitating the generation of a higher air volume and noise control. As shown in FIG. 7, the ratio of the noise value to the air volume in the case 110 can be minimized in a case 0.1≤Z₁/D≤0.16, where the range of the ratio of the noise value to the air volume in the case 110 is between 5.08 and 5.2, for example, but not limited to the following five types: when Z₁/D=0.1, the ratio of the noise value to the air volume is 5.2; when Z₁/D=0.12, the ratio of the noise value to the air volume is 5.12; when Z₁/D=0.13, the ratio of the noise value to the air volume is 5.09; when Z₁/D=0.14, the ratio of the noise value to the air volume is 5.07; and when Z₁/D=0.16, the ratio of the noise value to the air volume is 5.09.

As shown in FIG. 1, in some embodiments, the bottom of the case 110 is also provided with a compressor assembly, and embodiments of the present disclosure propose setting the distance between the bottom of the electronic control box 20 to the bottom of the case 110 to be Z₂, Z₂≥0.8×h, where h is the height of the compressor assembly within the case 110, to ensure assembly and maintenance feasibility.

At the same time, by defining the Z₁value and the Z₂value, it is also possible to define the overall height of the electronic control box 20, that is to say, the embodiment of the present application actually indirectly defines the height dimension of the electronic control box 20 based on defining the top position and the bottom position of the electronic control box 20, to achieve the purpose of adjusting the air volume and noise by adjusting the size and position of the electronic control box 20.

The compressor assembly includes a compressor 40 and a mounting support, where the mounting support is provided on a baseplate 102 of a box body 111, the compressor 40 is mounted on the baseplate 102 of the box body 111 via the mounting support, and the height of the compressor assembly includes the height of the compressor 40 and the height of the mounting support.

The support beam 104 of the present application does not define a shape. A structure located at the middle part of the top of the case 110 and connecting two sides of the top of the case 110 for increasing the strength of the top of the case 110 can be understood as a support beam 104.

Assembly and maintenance replacement of the electronic control box 20 and the type C heat exchanger is facilitated.

As shown in FIGS. 6, 3 and 11, in some embodiments, the air conditioning outdoor unit 100 includes two heat exchangers 30 oppositely disposed in the length direction, and the length of the electronic control box 20 is a, 0.32×A≤a≤K, where A is the entire length of the air conditioning outdoor unit 100, and F is the length of the gap (F in FIG. 11), K being a smaller value between 0.95×F and 0.9×A.

The embodiment of the present application proposes that two adjacent heat exchangers 30 cooperate to form a gap for mounting the electronic control box 20, to reduce interference between the electronic control box 20 and the heat exchangers 30 during the process of crossing the air conditioning outdoor unit 100, and reducing the influence of the electronic control box 20 on the air volume and noise in the case 110 by defining the length a of the electronic control box 20.

Referring to FIGS. 6 and 11, in some embodiments, the air conditioning outdoor unit 100 may include two wind turbines 10, one wind guiding ring 13 is provided at the air outlet of each wind turbine, and (W+√{square root over (R²−(R−T)²))}−L₀≤L≤√{square root over (R²−(R−T)²)}, where W is the width of the electronic control box 20, R is the inner diameter of the wind guiding ring 13 of the wind turbine 10, L₀is the axial distance between the two wind turbines 10, T is the width of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction, and L is the distance between one side of the electronic control box 20 to one side of the axial distance of the wind turbine 10 along the length direction of the air conditioning outdoor unit 100.

In the present embodiment, the part of the electronic control box 20 is located at the middle connection part of the two wind guiding rings 13 corresponding to the two wind turbines 10, and the middle connection part of the two wind guiding rings 13 is not located at the air channel of the air conditioning outdoor unit 100. The embodiment of the present application proposes that the air outlet side of each wind turbine 10 is provided with one wind guiding ring 13, and at least part of the electronic control box 20 is located below the two adjacent wind guiding rings 13, which can reduce the shielding of the air channel at the inlet of the wind turbine 10 by the electronic control box 20, facilitating the increase of the air volume and controlling the interference noise. In addition, on the basis that the overall length of the air conditioning outdoor unit 100 is fixed, the embodiments of the present application actually indirectly define the length dimension of the electronic control box 20 by defining the distance along the length direction of the whole air conditioning outdoor unit 100 from one side of the electronic control box 20 to one side of the axial center of the wind turbine 10, to achieve the purpose of adjusting the air volume and noise by adjusting the size and position of the electronic control box 20.

In some embodiments, the embodiments of the present application also provide that the electronic control box 20 is symmetrically distributed concerning the central axis of the vertical direction of the case, or symmetrically distributed concerning the support beam 104, and the distance from one side of the electronic control box 20 along the length direction to one side of the wind turbine axis is equal to the distance from the other side of the electronic control box 20 along the length direction to the other side of the wind turbine axis, that is to say, on the basis that the overall length of the air conditioning outdoor unit 100 is fixed. In the embodiments of the present application, based on defining the distance from one side of the electronic control box 20 to the axial center of one side of the wind turbine 10 along the entire length direction of the air conditioning outdoor unit 100 and defining the distance from the other side of the electronic control box 20 to the axial center of the other side of the wind turbine 10 along the entire length direction of the air conditioning outdoor unit 100, the length dimension of the electronic control box 20 is also indirectly defined, to achieve the purpose of adjusting the air volume of the wind turbine 10 and the noise of the wind turbine 10 by adjusting the size and position of the electronic control box 20.

In some embodiments, the electronic control box 20 is a closed electronic control box, to reduce wind within the case 110 from entering the interior of the electronic control box 20 and reducing the noise contribution of the electronic control box 20 to the airflow of the case 110.

In some embodiments, the embodiment of the present application sets the electronic control box 20 as a rectangular structure, and sets the length direction of the electronic control box 20 along the length direction of the machine case 110, to reduce the influence of the electronic control box 20 on the ventilation inside the machine case 110, and at the same time, the electronic control box 20 blocks the ventilation channel inside the machine case 110 in the width direction, and the embodiment of the present application proposes to minimize the width of the electronic control box 20, to reduce the influence of the electronic control box 20 on the wind volume and noise of the wind turbine 10.

In some embodiments, in the case where the size of the compressor 40 in the case 110 is small, and the internal space of the air conditioning outdoor unit 100 and the assembly allows, the vertical electronic control box 20 may be used, the electronic control box 20 is also provided in a rectangular structure, and the height direction of the electronic control box 20 is distributed along the height direction of the case 110, the height of the electronic control box 20 is greater than the length of the electronic control box 20, namely, the short side b of the electronic control box 20 is placed in a horizontal direction, and the long side a of the electronic control box 20 is placed along a vertical direction, so that the electronic control box 20 shields the inlet area of the wind turbine 10 to a minimum. As shown in FIG. 9, the horizontal electronic control box 20 is compared with the vertical discharge for a certain multi-line outdoor unit, and it can be seen therefrom that the noise of the wind turbine 10 can be minimized by means of the vertical electronic control box 20.

As shown in FIG. 9, for example, but not limited to the following five kinds: when the air volume is 22000 m³/h, the noise value of the electronic control box 20 horizontally is 61.6 dBA, the noise value of the electronic control box 20 vertically is 60.4 dBA, and the air volume is 23000 m³/h, the noise value of the electronic control box 20 horizontally is 62.5 dBA, the noise value of the electronic control box 20 vertically is 61.5 dBA, and the air volume is 24000 m³/h, the noise value of the electronic control box 20 horizontally is 64 dBA, the noise value of the electronic control box 20 vertically is 62.8 dBA, and the air volume is 25000 m³/h; when the noise value of the electronic control box 20 placed horizontally is 65 dBA, the noise value of the electronic control box 20 placed vertically is 64 dBA, and when the air volume is 26000 m³/h, the noise value of the electronic control box 20 placed horizontally is 66 dBA, and the noise value of the electronic control box 20 placed vertically is 65 dBA.

Third Embodiment

As shown in FIGS. 1 to 3, the present disclosure provides an air conditioning outdoor unit 100 including a case 110, a wind turbine 10 and an electronic control box 20, where the top of the case 110 is provided with an air outlet, the wind turbine 10 is arranged at the top of the case 110 and at the position of the air outlet, and the electronic control box 20 is arranged at the case 110, and 0.1×D≤Z₁≤0.2×D, where D is the diameter of the wind turbine 10, and Z₁is the distance from the top of the electronic control box 20 to the bottom of the wind turbine 10.

As shown in FIG. 7, through experiments, the ratio of the noise value to the air volume in the case 110 can be effectively reduced under satisfied 0.1×D≤Z₁≤0.2×D, and the loss of air volume and the noise caused by the electronic control box 20 can be reduced. As can be seen from FIG. 7 that the ratio of the noise value to the air volume in the case 110 can be minimized under 0.1≤Z₁/D≤0.16, and the ratio of the noise value to the air volume in the case 110 ranges between 5.08 and 5.2.

D has a range of values from 500 mm to 920 mm and may be, for example but not limited to: when D=500 mm, 50 mm≤Z₁≤100 m, when D=600 mm, 60 mm≤Z₁≤120 mm, when D=700 mm, 70 mm≤Z₁≤140 mm, when D=800 mm, 80 mm≤Z₁≤160 mm, when D=920 mm, 92 mm≤Z₁≤184 mm.

Alternatively, the distance from the top of the electronic control box 20 to the bottom of the wind turbine 10 described in the embodiments of the present disclosure is the minimum distance from the vertical distance from the top of the electronic control box 20 to the bottom of the wind turbine 10.

The present disclosure provides an air conditioning outdoor unit 100 including a case 110, an electronic control box 20, a heat exchanger 30, and a fan module 1000.

As shown in FIGS. 1 and 2, the case 110 includes a box body 111 and a panel 101. The box body 111 is opened with an opening (as shown in FIG. 1, the opening is located at the panel 101 on the right side of the case 110), and the panel 101 is movably connected to the opening to open or close the opening. For example, the panel 101 may be detachably coupled to the box body 111, or the panel 101 may be rotatably coupled to the box body 111. An air outlet is provided at the top of the box body 111.

The number of panels 101 may be one or more. A heat exchanger 30 is provided inside the case 110. An air outlet is provided at the top of the case 110. A fan module 1000 is provided at the top of the case 110 at the position of the air outlet. A mesh cover 103 is provided at the top of the case 110 on the air outlet side of the fan module 1000.

The electronic control box 20 is disposed in the case 110 at the opening, or the electronic control box 20 is disposed at one side of the case 110 near the panel 101, and the electronic control box 20 may be mounted on a support frame, both ends of which are mounted on two side plates of the box body 111 adjacent to the panel 101, or to a suspension bar extending downward of the motor bracket 12. The opening of the case 110 can be opened by adjusting the position of the panel 101 to service the electronic control box 20.

The fan module 1000 is used to create an airflow. The fan module 1000 may include a wind turbine 10, a motor 11, a motor bracket 12 and a wind guiding ring 13, the top plate of the electronic control box 20 is located below the motor bracket 12, and during the operation of the fan module 1000, air flows from the inside of the case 110 to the wind turbine 10 and flows out from an air outlet at the top. A mesh cover 103 may be provided at the air outlet.

It will be appreciated that both the heat exchanger 30 and the electronic control box 20 within the case 110 are located in the air flow path. The heat exchanger 30 is disposed around the periphery of the case 110, and the air path almost completely covers the inner space of the case 110. The electronic control box 20 is disposed in the inner space of the case 110, so that the electronic control box 20 blocks a part of the air path, resulting in a decrease in the air output of the air conditioning outdoor unit 100. At the same time, the presence of the electronic control box 20 interferes with the otherwise uniform airflow of the wind turbine 10, and the turbulent airflow of the wind turbine 10 creates additional aerodynamic noise.

To reduce the influence of the electronic control box 20 on the airfield and noise around the wind turbine 10, embodiments of the present application propose to improve the airfield and noise inside the case 110 by adjusting the position of the electronic control box 20.

Referring to FIGS. 1 to 3, a distance Z₁from the top of the electronic control box 20 to the bottom of the wind turbine 10 and a diameter D of the wind turbine 10 are sufficient to effectively improve the influence of the electronic control box 20 on the amount of wind and noise in the case 110 under 0.1×D≤Z₁≤0.2×D. In one embodiment, increasing the axial spacing between the electronic control box 20 and the wind turbine 10 (height direction as shown in FIG. 2) can reduce the effect of the electronic control box 20 on the air inlet flow field of the wind turbine 10.

In an embodiment, 0.14×D≤Z₁≤0.16×D is satisfied. In this way, the electronic control box 20 has a small influence on the wind turbine 10, facilitating the generation of a higher air volume and noise control. As shown in FIG. 7, under the condition that 0.1≤Z₁/D≤0.16 is satisfied, the ratio of the noise value to the air volume in the case 110 can be minimized, and at this time, the ratio range of the noise value to the air volume in the case 110 is between 5.08 and 5.2, for example, but not limited to: when Z₁/D=0.1, the ratio of noise value to air volume is 5.2, when Z₁/D=0.12, the ratio of noise value to air volume is 5.12, when Z₁/D=0.13, the ratio of noise value to air volume is 5.09, when Z₁/D=0.14, the ratio of noise value to air volume is 5.07, and when Z₁/D=0.16, the ratio of noise value to air volume is 5.09.

In the present embodiment, the bottom of the case 110 is provided with the baseplate 102, and the distance between the bottom of the electronic control box 20 and the baseplate 102 satisfies the Z₂range value, and the embodiment of the present disclosure sets the Z₂range value large enough to reduce the influence of the Z₂value on the Z value, that is, to satisfy the influence on the Z₂value based on the satisfied Z₁value. At the same time, by defining the Z₁value and the Z₂value, it is also possible to define the overall height of the electronic control box 20, that is to say, the embodiment of the present application actually indirectly defines the height dimension of the electronic control box 20 based on defining the top position and the bottom position of the electronic control box 20, to achieve the purpose of adjusting the air volume and noise by adjusting the size and position of the electronic control box 20.

The compressor assembly includes a compressor 40 and a mounting support, where the mounting support is provided on the baseplate 102 of the box body 111, the compressor 40 is mounted on the baseplate 102 of the box body 111 via the mounting support, and the height of the compressor assembly protects the height of the compressor 40 and the height of the mounting support.

As shown in FIGS. 4 and 5, in some embodiments, to reduce the obstruction of the ventilation duct by the electronic control box 20, the embodiment of the present disclosure also proposes that the projection dimension of the electronic control box 20 on the wind turbine 10 in the vertical direction has a width dimension T in the width direction, T satisfying T≤0.15×D.

In this embodiment, the width T of the projection of the electronic control box 20 on the wind turbine 10 in the vertical direction is the projection size of the part of the electronic control box 20 located in the inner space of the case 110 on the wind turbine 10.

As shown in FIG. 1, a wind guiding ring 13 is provided between the wind turbine 10 and the side wall of the box body 111 of the air conditioning outdoor unit 100, and the projection size of the portion of the electronic control box 20 located inside the case 110 described in the embodiment of the present application on the wind turbine 10 includes the width T1 of the portion of the electronic control box 20 located inside the case 110 minus the thickness T2 of the wind guiding ring 13.

Furthermore, the width of the projection of the electronic control box 20 on the wind turbine 10 along the vertical direction is T≤0.1×D, and the lower limit of the value range of T is determined according to the actual design requirements of the electronic control box 20; the presence of the electronic control box 20 blocks the air inlet of the wind turbine 10, and at the same time reducing the amount of air inlet, also causes the phenomenon of uneven air inlet of the wind turbine 10; and the embodiment of the present application is one of the effective methods for reducing the influence of the electronic control box 20 on the inlet flow field of the wind turbine 10 by reducing the width of the electronic control box 20. As shown in FIG. 8, through experiments, in the case T/D≤0.15, the influence of the electronic control box 20 on the flow field and noise at the inlet of the wind turbine 10 is minimal, the noise at the inlet of the wind turbine 10 can be reduced to 61.58 or less, for example, but not limited to: when T/D=0.1, the noise value is 61.4 dBA, when T/D=0.08, the noise value is 61.4 dBA, when T/D=0.06, the noise value is 61.3 dBA, when T/D=0.04, the noise value is 61.2 dBA, when=T/D=0.02, the noise value is 61.1 dBA.

As shown in FIG. 1, FIG. 3 and FIG. 10, according to some embodiments of the present disclosure, the air conditioning outdoor unit 100 includes a heat exchanger 30, the length of the electronic control box 20 is a, 0.5×A≤a≤K; A is the length of the whole unit of the air conditioning outdoor unit 100, E is the length of the gap (as shown in FIG. 10 or FIG. 12), and K is a smaller value between 0.95×E and 0.9×A.

In the present embodiment, by setting the length of the electronic control box 20 to a, and 0.5×A≤a≤K, it is possible to reduce the interference of the electronic control box 20 with the air conditioning outdoor unit 100 and the heat exchanger 30 while allowing for sufficient electronic components to be installed inside the electronic control box 20. Furthermore, since the wind guiding ring 13 and the blade tip clearance are provided between the wind turbine 10 and the case 110 of the air conditioning outdoor unit 100, the part of the electronic control box 20 along the length direction has less influence on the ventilation channel, the embodiments of the present application propose to set the length of the electronic control box 20 to a larger size range to meet the size limit of the electronic control box 20 in the width direction.

In some embodiments, the heat exchanger 30 of the air conditioning outdoor unit 100 is circumferentially disposed along the inner sidewall of the case 110 and provided with a gap (the length E of the gap is shown in FIG. 10) for disposing the electronic control box 20.

In the present embodiment, the shape of the heat exchanger 30 can be, for example, but is not limited to, a C-shaped structure, a G-shaped structure, an L-shaped structure or a U-shaped structure; the C-shaped heat exchanger is arranged around three sides of the case 110, so that the ventilation channel inside the case 110 is also distributed around the inner space of the case 110; the gap of the C-shaped heat exchanger is used for mounting the electronic control box 20, to reduce the influence of the electronic control box 20 on the airflow after the heat exchange is completed; and at the same time, arranging the electronic control box 20 at the gap of the C-shaped heat exchanger can also reduce the interference between the electronic control box 20 and the C-shaped heat exchanger. Assembly and maintenance replacement of the electronic control box 20 and the type C heat exchanger is facilitated.

As shown in FIGS. 6, 11, and 12, in some embodiments, the air conditioning outdoor unit 100 includes two heat exchangers 30 oppositely arranged in the length direction, the two heat exchangers 30 cooperating to form a gap, and the length of the electronic control box 20 is a, and 0.32×A≤a≤K, where A is the whole length of the air conditioning outdoor unit 100, F is the length of the gap (as shown in FIG. 12), and K is a smaller value between 0.95×F and 0.9×A.

As shown in FIG. 12, in some embodiments, the air conditioning outdoor unit 100 may be further provided with a U-type heat exchanger or a G-type heat exchanger, which is disposed around the inner wall of the case 110.

In some embodiments, the case 110 is a rectangular structure, the air outlet at the top of the case 110 is a rectangular structure or a circular structure, and the wind guiding ring 13 can be a circular structure. By arranging the electronic control box 20 inside the case 110, the electronic control box 20 can be located at the corner between the wind guiding ring 13 and the case 110, to minimize the interference of the electronic control box 20 on the air passage and improving the ventilation performance and noise reduction capability of the wind turbine 10.

As shown in FIG. 6, in some embodiments, the air conditioning outdoor unit 100 satisfies (W+√{square root over (R²−(R−T)²)})−L₀≤L≤√{square root over (R²−(R−T)²)}, where W is the width of the electronic control box 20, R is the inner diameter of the wind guiding ring 13 of the wind turbine 10, L₀is the axial distance between the two wind turbines 10, T is the dimension of the electronic control box 20 projected in the width direction on the wind turbine 10 in the vertical direction, and L is the distance between one side of the electronic control box 20 to one side of the axial distance of the wind turbine 10 in the length direction of the air conditioning outdoor unit 100.

In the present embodiment, the part of the electronic control box 20 is located at the middle connection part of the two wind guiding rings 13 of the two wind turbines 10, and the middle connection part of the two wind guiding rings 13 is not located at the air channel of the air conditioning outdoor unit 100; and the embodiment of the present application proposes that the air outlet of each wind turbine 10 is provided with one wind guiding ring 13, and at least part of the electronic control box 20 is located below the two adjacent wind guiding rings 13, which can reduce the shielding of the air channel at the inlet of the wind turbine 10 by the electronic control box 20, facilitating the increase of the air volume and controlling the interference noise. In addition, on the basis that the overall length of the air conditioning outdoor unit 100 is fixed, the embodiments of the present application actually indirectly define the length dimension of the electronic control box 20 by defining the distance along the length direction of the whole air conditioning outdoor unit 100 from one side of the electronic control box 20 to one side of the axial center of the wind turbine 10, to achieve the purpose of adjusting the air volume and noise by adjusting the size and position of the electronic control box 20.

In some embodiments, the electronic control box 20 is distributed symmetrically about a vertical central axis of the case, or alternatively, the electronic control box 20 is distributed symmetrically about the support beam 104. The distance from one side of the electronic control box 20 along the length direction to the axial center of one side wind turbine is equal to the distance from the other side of the electronic control box 20 along the length direction to the axial center of the other side wind turbine, that is to say, on the basis that the overall length of the air conditioning outdoor unit 100 is fixed, the embodiment of the present application defines the distance from one side of the electronic control box 20 to the axial center of one side wind turbine 10 along the length direction of the whole air conditioning outdoor unit 100, and defines the distance from the other side of the electronic control box 20 to the axial center of the other side wind turbine 10 along the length direction of the whole air conditioning outdoor unit 100; in fact, the length dimension of the electronic control box 20 is also indirectly defined, to achieve the purpose of adjusting the air volume of the wind turbine 10 and the noise of the wind turbine 10 by adjusting the size and position of the electronic control box 20.

In some embodiments, the embodiments of the present application do not define the relationship between the length and the height of the electronic control box 20, and in the case where the size of the compressor 40 in the case 110 is large, the embodiments of the present application propose distributing the length direction of the electronic control box 20 along the length direction of the case 110, and the length of the electronic control box 20 being greater than or equal to the height of the electronic control box 20, and reducing the interference between the electronic control box 20 and the compressor 40 in the case 110 by limiting the height of the electronic control box 20.

In some embodiments, in the case where the size of the compressor 40 inside the case 110 is small, and the internal space of the air conditioning outdoor unit 100 and the assembly allow, a vertical electronic control box 20 may be used, the electronic control box 20 is also provided in a rectangular structure, and the height direction of the electronic control box 20 is distributed along the height direction of the case 110, the height of the electronic control box 20 is greater than or equal to the length of the electronic control box 20, for example, the short side b of the electronic control box 20 is placed in a horizontal direction, and the long side a of the electronic control box 20 is placed along a vertical direction, so that the area of the inlet of the wind turbine 10 covered by the electronic control box 20 is minimized. As shown in FIG. 9, the horizontal and vertical electronic control boxes 20 are used in comparison for a certain multi-wind turbine multi-on-line outdoor unit, and it can be seen therefrom that the noise of the wind turbine 10 can be minimized by means of the vertical electronic control box 20.

As shown in FIG. 9, for example, but not limited to: when the air volume is 22000 m³/h, the noise value of the electronic control box 20 horizontally is 61.6 dBA, the noise value of the electronic control box 20 vertically is 60.4 dBA, and the air volume is 23000 m³/h, the noise value of the electronic control box 20 horizontally is 62.5 dBA, the noise value of the electronic control box 20 vertically is 61.5 dBA, and the air volume is 24000 m³/h, the noise value of the electronic control box 20 horizontally is 64 dBA, the noise value of the electronic control box 20 vertically is 62.8 dBA, and the air volume is 25000 m³/h; when the noise value of the electronic control box 20 placed horizontally is 65 dBA, the noise value of the electronic control box 20 placed vertically is 64 dBA, and when the air volume is 26000 m³/h, the noise value of the electronic control box 20 placed horizontally is 66 dBA, and the noise value of the electronic control box 20 placed vertically is 65 dBA.

Fourth Embodiment

As shown in FIGS. 1 to 3, 10, and 12, the present disclosure provides an air conditioning outdoor unit 100 including a case 110, a wind turbine 10, and an electronic control box 20, an air outlet provided on the top of the case 110, a heat exchanger 30 provided inside the case 110, a wind turbine 10 provided on the top of the case 110 and located at the air outlet, and an electronic control box 20 provided on the case 110, where the length of the electronic control box 20 is a, 0.5×A≤a≤K; A is the length of the whole unit of the air conditioning outdoor unit 100, E is the length of a gap between the heat exchanger 30 and the length of the electronic control box 20, and K is a smaller value between 0.95×E and 0.9×A.

In some embodiments, the air conditioning outdoor unit 100 proposed in the embodiments of the present application can flexibly adjust the area of the electronic control box 20 shielding the ventilation channel by reasonably setting the length of the electronic control box 20 under the premise of ensuring the normal operation and convenient assembly and disassembly of the electronic control box 20, and improve the air field and noise inside the case 110 by adjusting the length of the electronic control box 20, to minimize the influence of the electronic control box 20 on the ventilation and noise inside the air conditioning outdoor unit 100.

This embodiment does not limit the number of the wind turbines, and the number of the wind turbines may be one (as shown in FIG. 10), two (as shown in FIG. 12), or any other number.

In the embodiments of the present application, the shape of the heat exchanger is not limited. The shape of the heat exchanger 30 may be, for example, but not limited to, a C-type structure, a G-type structure, an L-type structure, or a U-type structure.

It can be understood that the heat exchanger 30 and the electronic control box 20 inside the case 110 are both located in an air passage of the airflow, the heat exchanger 30 is used for heat exchange of the airflow at the air passage, and since the heat exchanger 30 is arranged around the periphery of the case 110, the air passage almost completely covers the inner space of the case 110. The electronic control box 20 is arranged in the inner space of the case 110, and the electronic control box 20 blocks a part of the ventilation channel, which may reduce the air output of the air conditioning outdoor unit 100; at the same time, the existence of the electronic control box 20 also interferes with the originally uniform airflow around the wind turbine 10, and the turbulent airflow around the wind turbine 10 may also generate additional pneumatic noise.

In some embodiments, the embodiments of the present application provide the heat exchanger 30 to both maximize the coverage of the inner space of the case 110 and provide sufficient installation space for the electronic control box 20. In the case that the case 110 is a rectangular structure, the heat exchanger 30 is circumferentially arranged along the inner side wall of the case 110 and is provided with a gap (the length E of the gap is shown in FIG. 10) for installing the electronic control box 20.

At the same time, the embodiment of the present application proposes 0.5×A≤a≤K; A is the length of the whole air conditioning outdoor unit 100, E is the length of the gap on the heat exchanger 30 in the case 110 corresponding to the electronic control box 20, K being a smaller value between 0.95×E and 0.9×A; it can be seen therefrom that the electronic control box 20 occupies a sufficiently large space along the length direction; since the wind turbine 10 and the case 110 of the air conditioning outdoor unit 100 are provided with a wind guiding ring 13 and the blade tip clearance, and part of the wind guiding ring 13 and the blade tip clearance are close to the case 110, the air channel located inside the case 110 does not include the wind guiding ring 13 and the blade tip clearance; the portion of the electronic control box 20 along the length direction has less influence on the air duct, and the embodiment of the present application proposes to set the length of the electronic control box 20 to a larger size range, to reduce the influence of the electronic control box 20 on the air volume and noise of the wind turbine 10.

In some embodiments, as shown in FIGS. 4 and 5, in some embodiments, to reduce the obstruction of the air duct by the electronic control box 20, the embodiment of the present disclosure also proposes that the width of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction is T, T satisfying T≤0.15×D.

In this embodiment, the electronic control box 20 is integrally located in the inner space of the case 110, and the projected width dimension of the electronic control box 20 falling on the wind turbine 10 in the vertical direction is the projected width dimension of the part of the electronic control box 20 located in the inner space of the case 110 on the wind turbine 10. A wind guiding ring 13 is provided between the wind turbine 10 and the case 110 of the air conditioning outdoor unit 100, and the projection size of the part of the electronic control box 20 located inside the case 110 on the wind turbine 10 in the embodiment of the present application includes the width of the part of the electronic control box 20 located inside the case 110 minus the thickness of the wind guiding ring 13.

Furthermore, the width dimension of the electronic control box 20 falling on the projection of the wind turbine 10 along the vertical direction is T≤0.1×D, and the lower limit of the value range of T is determined according to the actual design requirements of the electronic control box 20; the existence of the electronic control box 20 blocks the air inlet of the wind turbine 10, and at the same time reducing the amount of air inlet, also causes the phenomenon of uneven air inlet of the wind turbine 10; and the embodiment of the present application is one of the effective methods for reducing the influence of the electronic control box 20 on the inlet flow field of the wind turbine 10 by reducing the width of the electronic control box 20. As shown in FIG. 8, through experiments, in the case T/D≤0.15, the influence of the electronic control box 20 on the flow field and noise at the inlet of the wind turbine 10 is minimal, the noise at the inlet of the wind turbine 10 can be reduced to 61.58 or less, for example, but not limited to: when T/D=0.1, the noise value is 61.4 dBA, when T/D=0.08, the noise value is 61.4 dBA, when T/D=0.06, the noise value is 61.3 dBA, when T/D=0.04, the noise value is 61.2 dBA, when=T/D=0.02, the noise value is 61.1 dBA.

Alternatively, a support beam 104 is provided in the middle part of the case 110, and at least part of the electronic control box 20 is located below the support beam 104. Since the support beam 104 is not located below the air channel of the air conditioning outdoor unit 100, the embodiments of the present application propose that at least part of the electronic control box 20 is located below an adjacent support beam 104, so that the shielding of the air channel at the inlet of the wind turbine 10 by the electronic control box 20 can be reduced, facilitating the lifting of the air volume and controlling the interference noise.

As shown in FIGS. 11 and 12, in some embodiments, the air conditioning outdoor unit 100 includes two heat exchangers 30 oppositely disposed in a length direction, which cooperate to form gaps for mounting the heat exchangers.

As shown in FIG. 11, the length of the electronic control box 20 is a, and 0.32×A≤a≤K, where A is the whole length of the air conditioning outdoor unit 100, and F is the length of the gap, K being a smaller value between 0.95×F and 0.9×A.

In the embodiment of the present application, two adjacent heat exchangers 30 cooperate to form a gap for mounting the electronic control box 20, to reduce interference between the electronic control box 20 and the heat exchangers 30 during the process of crossing the air conditioning outdoor unit 100, and reducing the influence of the electronic control box 20 on the air volume and noise in the case 110 by defining the length a of the electronic control box 20.

As shown in FIG. 12, in some embodiments, the air conditioning outdoor unit 100 includes a U-type heat exchanger (FIG. 12) or a G-type heat exchanger (not shown), which is disposed around the inner wall of the case 110. The width F of the gap satisfies the range mentioned in the above embodiment.

In some embodiments, as shown in FIGS. 1-3, according to an embodiment of the present application, the distance between the top of the electronic control box 20 and the bottom of the wind turbine 10 is Z₁, then 0.1×D≤Z₁≤0.2×D, where D is the diameter of the wind turbine 10 and Z₁is the distance between the top of the electronic control box 20 and the bottom of the wind turbine 10.

In some embodiments, the air conditioning outdoor unit 100 reduces the adverse effect of the electronic control box 20 on the air conditioning outdoor unit 100 and reduces the air volume loss and the noise caused by the electronic control box 20 by rationally arranging the distance between the electronic control box 20 and the wind turbine 10 on the premise that the electronic control box 20 is ensured to be normally operated and conveniently maintained. The distance between the top of the electronic control box 20 to the bottom of the wind turbine 10 described in the embodiments of the present disclosure is the minimum distance of the vertical distance between the top of the electronic control box 20 to the bottom of the wind turbine 10.

In particular, if the distance between the top of the electronic control box 20 and the bottom of the wind turbine 10 is Z₁, and the diameter of the wind turbine 10 is D, the influence of the electronic control box 20 on the air volume and noise in the case 110 can be effectively improved if 0.1×D≤Z₁≤0.2×D satisfied, the internal structure and size of the case 110 have a greater influence on the air volume and noise in the case 110, and the air volume and noise generated by different cases 110 are different, and an example of all the different cases 110 will not be given here. As shown in FIG. 7, the embodiments of the present application only illustrate that the amount of wind and noise within one type of case 110 is affected by the distance Z₁from the top of the electronic control box 20 to the bottom of the wind turbine 10. In one embodiment, by increasing the axial spacing between the electronic control box 20 and the wind turbine 10, the effect of the electronic control box 20 on the flow field at the inlet of the wind turbine 10 can be reduced, and within the above-mentioned distance 0.14×D≤Z₁≤0.16×D range, in particular within the range, the effect of the electronic control box 20 on the wind turbine 10 is small, facilitating the generation of a higher air volume and the control of noise.

As shown in FIG. 7, when satisfied 0.1≤Z₁/D≤0.16, the ratio of the noise value to the air volume in the case 110 can be minimum, and in this case, the ratio of the noise value to the air volume in the case 110 is between 5.08 and 5.2, for example, but not limited to: when Z₁/D=0.1, the ratio of noise value to air volume is 5.2, when Z₁/D=0.12, the ratio of noise value to air volume is 5.12, when Z₁/D=0.13, the ratio of noise value to air volume is 5.09, when Z₁/D=0.14, the ratio of noise value to air volume is 5.07, and when Z₁/D=0.16, the ratio of noise value to air volume is 5.09.

In some embodiments, the distance from the bottom of the electronic control box 20 to the bottom of the case 110 is Z₂, Z₂≥0.8×h, where Z₂=H−b, then (H−b)≥0.8 h, H being the vertical distance from the top of the electronic control box 20 to the bottom of the case 110, and h being the height of the compressor assembly.

In the present embodiment, the embodiment of the present application proposes to improve the airfield and noise inside the case 110 by adjusting the position of the electronic control box 20. In one embodiment, under the premise of ensuring the normal operation and convenient maintenance of the air conditioning outdoor unit, by rationally arranging the distance between the electronic control box 20 and the bottom of the case, the height direction of the electronic control box 20 can be flexibly adjusted, to reduce the influence of the electronic control box 20 on the ventilation and noise inside the air conditioning outdoor unit.

In addition, the embodiments of the present application can also achieve the purpose of defining the overall height of the electronic control box 20 by defining Z₁value and Z₂value, that is to say, the embodiments of the present application actually indirectly define the overall height dimension of the electronic control box 20 based on defining the top height and the bottom height of the electronic control box 20, to achieve the purpose of adjusting the air volume and noise at the wind turbine 10 by adjusting the size and height position of the electronic control box 20.

Referring to FIGS. 6 and 11, in some embodiments, the air conditioning outdoor unit 100 may include two wind turbines 10, one wind guiding ring 13 is provided at the air outlet of each wind turbine, and (W+√{square root over (R²−(R−T)²)})−L₀≤L≤√{square root over (R²−(R−T)²)}, where W is the width of the electronic control box 20, R is the inner diameter of the wind guiding ring 13 of the wind turbine 10, L₀is the axial distance between the two wind turbines 10, T is the width dimension of the projection of the electronic control box 20 falling on the wind turbine 10 in the vertical direction, and L is the distance between one side of the electronic control box 20 and one side of the axial center of the wind turbine 10 along the length direction of the air conditioning outdoor unit 100.

In the present embodiment, the part of the electronic control box 20 is located at the middle connection part of the two wind guiding rings 13 of the two wind turbines 10, and the middle connection part of the two wind guiding rings 13 is not located at the air channel of the air conditioning outdoor unit 100. The embodiment of the present application proposes that the air outlet side of each wind turbine 10 is provided with one wind guiding ring 13, and at least part of the electronic control box 20 is located below the two adjacent wind guiding rings 13, which can reduce the shielding of the air channel at the inlet of the wind turbine 10 by the electronic control box 20, facilitating the increase of the air volume and controlling the interference noise. In addition, on the basis that the overall length value of the air conditioning outdoor unit 100 is fixed, the embodiment of the present application actually indirectly defines the length dimension of the electronic control box 20 by defining the distance along the length direction from one side of the electronic control box 20 to one side of the axial center of the wind turbine 10, to achieve the purpose of adjusting the air volume and noise by adjusting the size and position of the electronic control box 20.

In addition, the embodiment of the present application also provides that the electronic control box 20 is symmetrically distributed with respect to the central axis of the vertical direction of the box body or symmetrically distributed with respect to the support beam 104, and the distance from one side of the electronic control box 20 along the length direction to the axial center of one side wind turbine is equal to the distance from the other side of the electronic control box 20 along the length direction to the axial center of the other side wind turbine, that is to say, on the basis that the overall length of the air conditioning outdoor unit 100 is fixed, the embodiment of the present application defines the distance from one side of the electronic control box 20 to the axial center of one side wind turbine 10 along the length direction of the whole air conditioning outdoor unit 100. And based on defining the distance from the other side of the electronic control box 20 to the axial center of the wind turbine 10 along the length direction of the whole machine, the length dimension of the electronic control box 20 is also indirectly defined, to achieve the purpose of adjusting the air volume of the wind turbine 10 and the noise of the wind turbine 10 by adjusting the size and position of the electronic control box 20. The support beam 104 of the present application does not define a shape. A structure located at the middle part of the top of the case 110 and connecting two sides of the top of the case 110 for increasing the strength of the top of the case 110 can be understood as a support beam 104.

In some embodiments, in the case where the size of the compressor 40 inside the case 110 is small, and the internal space of the air conditioning outdoor unit 100 and the assembly allow, it is possible to adopt the manner of the vertical electronic control box 20, the electronic control box 20 is also provided in a rectangular structure, and the height direction of the electronic control box 20 is distributed along the height direction of the case 110, and the height of the electronic control box 20 is greater than the length of the electronic control box 20, namely, the short side b of the electronic control box 20 is placed in a horizontal direction, and the long side a of the electronic control box 20 is placed along a vertical direction, so that the area of the electronic control box 20 shielding the inlet of the wind turbine 10 is minimized. As shown in FIG. 9, the horizontal electronic control box 20 is compared with the vertical discharge for a certain multi-line outdoor unit, and it can be seen therefrom that the noise of the wind turbine 10 can be minimized by means of the vertical electronic control box 20.

For example, but not limited to: when the air volume is 22000 m³/h, the noise value of the electronic control box 20 horizontally is 61.6 dBA, the noise value of the electronic control box 20 vertically is 60.4 dBA, and the air volume is 23000 m³/h, the noise value of the electronic control box 20 horizontally is 62.5 dBA, the noise value of the electronic control box 20 vertically is 61.5 dBA, and the air volume is 24000 m³/h, the noise value of the electronic control box 20 horizontally is 64 dBA, the noise value of the electronic control box 20 vertically is 62.8 dBA, and the air volume is 25000 m³/h; when the noise value of the electronic control box 20 placed horizontally is 65 dBA, the noise value of the electronic control box 20 placed vertically is 64 dBA, and when the air volume is 26000 m³/h, the noise value of the electronic control box 20 placed horizontally is 66 dBA, and the noise value of the electronic control box 20 placed vertically is 65 dBA.
