DETAILED DESCRIPTION

In order to further illustrate the principle and structure of the disclosure, the embodiments of the disclosure will be described in detail with reference to the accompanying drawings.

In an embodiment, the disclosure provides an air conditioner apparatus which is an all-in-one machine. Compared with the structure in which the indoor unit and the outdoor unit of the traditional air conditioner apparatus are independent of each other, the indoor unit and the outdoor unit of the air conditioner apparatus of this embodiment are integrated in the same apparatus, that is, the evaporation device and the condensation device are integrated in the same apparatus. The all-in-one machine can exhaust the hot air generated therein through the exhaust tube.

Specifically, as shown in FIG. 1 and FIG. 2, FIG. 1 is a schematic perspective view of an air conditioner apparatus in an embodiment, and FIG. 2 is a section view of FIG. 1, the air conditioner apparatus 100 includes an evaporation device 10, a condensation device 20, a refrigerant compressor 30, a refrigerant filter 40 and a throttling device 50. The refrigerant compressor 30, the condensation device 20, the refrigerant filter 40 and the throttling device 50 are sealed in a closed box 101, and the evaporation device 10 is arranged outside the closed box 101. An air inlet port 102 and an exhaust port 103 are opened on the closed box 101, and the air inlet port 102 is connected to air inlet of the condensation device 20, the exhaust port 103 is connect to the air outlet of the condensation device 20. An exhaust tube is connected to the exhaust port 103, and is long enough so that the port of the exhaust tube can extend outdoors, so as to discharge the hot air after heat exchange with the condensation device 20 to outside. A control panel 105 is further arranged on the closed box 101, and a control circuit electrically connected to the control panel 105 is further arranged in the closed box 101.

The evaporation device 10 and the condensation device 20 are vertically fixed on the same seat body 104, so that the evaporation device 10 and the condensation device 20 are integrated together to form an integrated machine.

The above-mentioned seat body 104 and the above-mentioned closed box 101 can be integrally formed.

As shown in FIG. 3, FIG. 3 is a cross-sectional view of the air conditioner apparatus in an embodiment. The evaporation device 10 is roughly cylindrical, with a fan 61 arranged on the top, and an airflow opening 10a is arranged on the bottom end away from the fan 61 for airflow in and out. The fan 61 may be a suction fan or a blower. When the fan 61 is a blower, the fan 61 sucks in the air in the atmosphere from the top of the evaporation device 10 and sends it into the evaporation device 10. After the heat exchange is completed, the temperature of the air decreases and blows out into the room from the airflow opening 10a. When the fan 61 is a suction fan, the fan 61 sucks in air from the bottom of the evaporation device 10 through the airflow opening 10a. The sucked air is cooled in the evaporation device 10, and the cooled air finally flows out into the room through the fan outlet at the top.

It can be understood that, in an embodiment, the fan 61 may also be arranged at the bottom of the evaporation device 10, and in this case, the airflow opening for air flow in and out is arranged at the top.

At least one of the evaporation device 10 and the condensation device 20 comprises the heat exchange structure of the disclosure. The specific structure of the heat exchange structure is described in detail below by taking the heat exchange structure included in the evaporation device as an example.

Specifically, in an embodiment, as shown in FIG. 4 and FIG. 5, FIG. 4 is a front view of a heat exchange structure in an embodiment of the disclosure, and FIG. 5 is a schematic cross-sectional view along A-A in FIG. 4. The heat exchange structure 1a includes a housing 11, and a plurality of medium tubes 12 and a plurality of fins 13 arranged in the housing 11. The inner of each medium tube 12 is formed with a medium circulating channel 121.

The housing 11 includes an upper end opening and a lower end opening. Air flows in from the upper end opening and flows out from the lower end opening. In actual applications, the airflow can also flow in from the lower end opening of the housing 11 and flow out from the upper end opening. The housing 11 has a circular tube shape. In other embodiments, the housing 11 may also have a square tube shape or other shape.

The housing 11 can be integrally molded by extrusion with the medium tube 12 and the fins 13. In addition, the housing 11 can also be formed independently of the medium tube 12 and the fins 13, and the medium tube 12 and the fins 13 are integrally molded by extrusion, that is, the medium tube 12 and the fin 13 are formed and then the housing 11 is put thereon.

The housing 11, the medium tube 12 and the fin 13 can be integrally molded by metal extrusion. The metal can be aluminum alloy or other materials with good heat transfer. This molding method makes the distribution of the medium tube 12 and the fin 13 more uniform and compact. Compared with the welding molding method, the gap size between the fins 13 can also become smaller, and to a certain extent, the heat exchange area is increased, thereby improving heat exchange efficiency; and the integrated molding method increases the accuracy of device molding and reduces the difficulty of manufacturing. In this way, the heat exchange device can be designed to be smaller, achieving the purpose of reducing the size and meeting people's desire for miniaturization. In addition, the integrated molding method can also improve production efficiency and reduce costs.

The heat exchange structure 1a includes a plurality of medium tubes 12 and a plurality of fins 13 arranged in the housing 11. One medium tube 12 of the plurality of the medium tubes 12 is located at the geometric center of the heat exchange device, and the remaining medium tubes 12 are radially distributed around the geometric center. The fins 13 are connected between the medium tubes 12. Arranging the medium tube 12 in this way can improve the heat exchange efficiency between the medium in the medium tube 12 and the fins, and increase the range of the airflow heating or cooling. In addition, the arrangement of the plurality of the medium tubes 12 increases the amount of medium entering the heat exchange device, which means that it can exchange heat with a larger amount of airflow, thereby improving efficiency and reducing time.

It should be noted that the geometric center of the heat exchange structure 1a can be determined according to its cross-sectional shape. For example, in FIGS. 4 and 5, the heat exchange device is cylindrical as a whole, whose cross-section is circular, and whose geometric center is the center of the circular section. For another example, if the cross section of the heat exchange device is square or rectangular, its geometric center is the intersection of two diagonal lines. And so on, they are not listed in detail herein.

Furthermore, as shown in FIG. 5, the plurality of medium tubes 12 are distributed on a plurality of circumferences with different radii around the center of the circular cross section of the heat exchange structure 1a. Specifically, with the medium tube 12 in the center as the center, the remaining medium tubes 12 are arrayed to a plurality of circles with different radii, and a plurality of medium tubes 12 are arranged at equal intervals or unequal intervals on each circle. With this arrangement, the medium tubes 12 can be evenly distributed at each position of the heat exchange structure 1a, so that the medium in the medium tube 12 can evenly exchange heat with the airflow, and ensure that the temperature of the airflow after heat exchange is uniform.

Each medium tube 12 forms a medium circulating channel 121. Due to the layout of the medium tube 12, the medium circulating channels 121 can be divided into multiple groups. Each group of medium circulating channels 121 are distributed at intervals in the circumferential direction around the center which is the center of the heat exchange structure 1a, and different groups of medium circulating channels 121 are distributed on circles with different radii.

Each medium circulating channel 121 extends in a height direction of the housing 11, and runs from an upper end of the housing 11 through to a lower end of the housing 11. As a result, the heat exchange efficiency per unit area is increased.

The fin 13 extends in the height direction of the medium tube 12 and extends from the upper end to the lower end of the medium tube 12. In this way, the heat dissipation area can be increased and the heat transfer efficiency can further be improved. The outer wall of each medium tube 12 is connected with the fin 13. Specifically, the fin 13 is connected to the medium tube 12 located at the geometric center and extends in the radial direction thereof, that is, the fin 13 can extend from the medium tube 12 located at the geometric center to the housing 11.

Specifically, a plurality of fins 13 are arranged between the medium circulating channels 121 and between the housing 11 and the medium circulating channel 121. A gap 131 for airflow passage is formed between the fins 13. The fins 13 are distributed radially with the center line of the housing 11 as the center (or with the medium tube 12 located at the geometry center as the center), and are evenly arranged on the outer periphery of each medium circulating channel 121. This distribution of the fins 13 increase the number of fins 13 arranged per unit area and increase the integration of the fins 13 per unit area, thereby improving the heat transfer efficiency per unit area. As a result, the evaporation device and/or the condensation device can be designed to be smaller, greatly reducing the size of the air conditioner apparatus.

The medium circulating channels 121 may be communicated in series or in parallel through connecting tubes. In one embodiment, as shown in FIG. 4, a connecting tube 141 is provided at the lower end of the housing 11, and the connecting tube 141 can be communicated in parallel with a plurality of medium circulating channels 121 along the radial direction of the housing 11 at the lower end of the housing 11. As shown in FIG. 6 and FIG. 7, FIG. 6 is a top view of FIG. 4, and FIG. 7 is a bottom view of FIG. 4. A refrigerant medium inlet 151 is arranged at the lower end of the housing 11, which is communicated with the connecting tube 141 at the lower end of the housing 11, and the refrigerant medium flows into the medium circulating channels 121 connected to the connecting tube 141 through the refrigerant medium inlet 151 and the connecting tube 141. The medium circulating channels 121 that are not communicated with the connecting tube 141 can be communicated with the medium circulating channels 121 through which the refrigerant medium passes by another connecting tube 142, and finally there is refrigerant medium circulating in each medium circulating channel 121. A refrigerant medium outlet 152 is arranged at the lower end of the housing 11, through which the refrigerant medium in the medium circulating channel 121 flows out.

In an embodiment, the heat exchange structure 1a may be provided with one refrigerant medium inlet and one refrigerant medium outlet, and the medium circulating channel 121 in the housing 11 are communicated in series through connecting tubes.

In an embodiment, the medium circulating channels 121 may be communicated in parallel. Specifically, the upper end and the lower end of the housing of the heat exchange structure 1a are respectively provided with an inlet manifold and an outlet manifold. The upper port of each medium circulating channel 121 is communicated with the inlet manifold, and the lower port of each medium circulating channel 121 is communicated with the outlet manifold. The refrigerant medium flows from the inlet manifold into each medium circulating channel 121, passes through each medium circulating channel 121 and then converges in the outlet manifold, and finally flows out from the outlet manifold.

The location and quantity of the refrigerant medium outlet and refrigerant medium inlet can be changed according to the actual application. The communication between the medium circulating channels may be serial communication, or parallel communication, or partial serial communication and partial parallel communication.

In addition, the number of medium circulating channels can be determined according to actual applications. For example, the number of medium circulating channels is more than two, which has a better cooling effect.

In another embodiment, as shown in FIG. 8, FIG. 8 is a schematic cross-sectional view of a heat exchange device in another embodiment. The heat exchange structure 1b is integrally molded by extrusion, and the heat exchange structure 1b is formed with at least one medium circulating channel 161, and a plurality of fins 17 are formed on the outer periphery of the medium circulating channel 161, and arranged at intervals to form gaps 18 allowing airflows to pass therethrough.

The heat exchange structure 1b has a cylindrical shape as a whole and its cross-section is circular.

As shown in FIG. 8, the heat exchange structure 1b includes a plurality of medium circulating channels 161. A part of the medium circulating channels 161 are formed by the medium tubes 16, and the other part of the medium circulating channels 161 are formed by the fins 17.

The heat exchange structure 1b includes a medium tube 16 located at the geometric center of the heat exchange structure 1b. It can be understood that the heat exchange structure 1b may include a plurality of medium tubes 16, one of which is located at the geometric center of the heat exchange structure 1b. The other part of the medium circulating channels 161 formed by the fins 17 is distributed in a circumference around the medium tube 16 at the geometric center.

A plurality of the fins 17 are arranged on the outer peripheral wall of the medium tube 16 at intervals. The fins 17 extend in the height direction of the medium tube 16 and extend in the radial direction from the medium tube 16 located at the geometric center.

The fins 17 are fork-shaped or pliers-shaped. The fork-shaped fin 171 includes a rod part 1711 and a bifurcation part 1712. The rod part 1711 is connected with the medium tube 16 located at the geometric center, and the bifurcation part 1712 is connected with the rod part 1711. The pliers-shaped fin 172 includes two oppositely arranged special-shaped fins 1721, 1722. The end of the special-shaped fin 1721, 1722 away from the geometric center is arc-shaped, and the arc-shaped ends of the two special-shaped fins 1721, 1722 enclose to form the above-mentioned medium circulating channel 161. The medium circulating channel 161 extends from the upper end of the fin 17 to the lower end of the fin 17, that is, the medium circulating channel 161 formed by the enclosing of the fins 17 and the medium circulating channel 161 formed by the medium tubes 16 are equal in height. Here, the fins 17 are arranged in a fork shape or a pincer shape to increase the heat exchange area and improve the heat exchange efficiency.

As shown in FIG. 8, the pliers-shaped fin 172 includes four fins 172, which are respectively located directly above, directly below, directly left and directly right of the center of the circular cross section. However, it is not limited to this, and the number and position of the pliers-shaped fins 172 can be varied.

As mentioned above, the pliers-shaped fins 172 can form a medium circulating channel 161 for the passage of the medium. In addition, the medium circulating channel 161 formed by the pliers-shaped fins 172 can also be configured to be inserted a support rod so that the heat exchange device can be supported on the ground or on other equipment, for example, in FIG. 8, the medium circulating channels 161 located directly on the left and right are configured to circulate the media, and the support rods are inserted into the two medium circulating channels 161 located directly above and directly below for supporting. In this way, the medium circulating channel 161 has two functions, and can be configured to be inserted a support rod when not configured for circulation of the medium.

Continuing to refer to FIG. 8, the inner wall of the medium tube 16 protrudes inwardly to form a plurality of protrusions 162, and the plurality of protrusions 162 are circumferentially distributed along the inner wall of the medium tube 16. In this way, the heat exchange area of the medium tube 16 can be increased, and the heat exchange efficiency can be improved.

Further, as shown in FIG. 9, FIG. 9 is a schematic cross-sectional of a heat exchange device provided with housing in another embodiment, the heat exchange structure 1b further comprises a housing 19 that covers the medium tube 16 and fins 17. The housing 19 is integrally molded by extrusion with the medium tube 16 and the fins 17, or the medium tube 16 and the fins 17 are molded by extrusion and the housing 19 is formed independently of the medium tube 16 and the fins 17.

The housing 19, the medium tube 16 and the fins 17 can be all made of aluminum alloy. The aluminum alloy material has good thermal conductivity, thereby can improve the heat exchange efficiency of the heat exchange structure 1b.

Both the condensation device 20 and the evaporation device 10 can adopt the heat exchange structure of any one of the above-mentioned embodiments or a structure with equivalent changes made according to the heat exchange structure. The cooling medium circulating in the medium circulating channel 121 is a refrigerant, for example, a cooling medium such as Tetrafluoroethane or Freon. When the condensation device 20 adopts the above-mentioned heat exchange structure 1a (or 1b), the refrigerant which is passed into the medium circulating channel 121 is the high-temperature and high-pressure refrigerant. A fan 61 is arranged on the end of the condensation device 20, and sweeps the outer wall of the medium circulating channel 121 and the fin 13 to take away heat, so that the temperature of the refrigerant in the medium circulating channel 121 is lowered, achieving the purpose of cooling the refrigerant. When the evaporation device 10 adopts the above heat exchange structure 1a (or 1b), the refrigerated refrigerant is passed into the medium circulating channel 121, and the air to be cooled is passed into the housing 11 to exchange heat with the refrigerant in the medium circulating channel 121. The heat is absorbed and the air temperature drops, which achieves the purpose of cooling the air.

Both the evaporation device 10 and the condensation device 20 adopt the above heat exchange structure, so that the evaporation device 10 and the condensation device 20 can be designed to be smaller, thus greatly reducing the size of the air conditioner apparatus.

In the above embodiment, the evaporation device 10 and the condensation device 20 both adopt the above-mentioned heat exchange structure to realize heat exchange, but it is not limited to this, and it may also one of the evaporation device 10 and the condensation device 20 that adopts the above-mentioned heat exchange structure. In other words, another device that does not adopt the above-mentioned heat exchange structure can adopt the traditional heat exchange structure to realize heat exchange.

The evaporation device 10 is configured to cool the indoor air. As mentioned above, under the action of the fan 61, the outside wind enters the evaporation device 10 and passes through the gap 131 between the fins 13 from the upper end of the housing 11 to the lower end of the housing 11 (or from the lower end of the housing 11 to the upper end of the housing 11), contacts the outer wall of the medium circulating channel 121 for heat exchange. The refrigerant in the medium circulating channel 121 absorbs heat and vaporizes. The temperature of the absorbed air decreases and the absorbed air flows out of the housing 11.

The refrigerant connecting tube 10b at the inlet end of the evaporation device 10 is connected to the refrigerant tube of the throttling device 50, and the refrigerant connecting tube 10c at the outlet end of the evaporation device 10 is connected to the refrigerant tube of the refrigerant compressor 30 to input the vaporized refrigerant to the refrigerant compressor 30 for compression.

The refrigerant connecting tube 20b at the outlet end of the condensation device 20 is connected to the refrigerant tube of the refrigerant filter 40. The refrigerant filter 40 is configured to filter impurities in the medium-temperature and high-pressure liquid refrigerant output from the condensation device 20. The refrigerant tube at the output end of the refrigerant filter 40 is connected to the refrigerant tube of the throttling device 50, and the throttling device 50 decompress the medium-temperature and high-pressure liquid refrigerant filtered by the refrigerant filter 40 into the low-temperature and low-pressure liquid refrigerant, and deliver into the evaporation device 10. The throttling device 50 may be an expansion valve or a capillary tube.

The fan 61 at the end of the condensation device 20 may be a blower. The blower draws air in the atmosphere from the end of the condensation device 20 and sends it to the inside of the condensation device 20 for heat exchange. The heat-absorbed air is transported to the exhaust port 103 through the ventilation tube 21 at the bottom of the condensation device 20, and then is exhausted to the outside through the exhaust tube at the exhaust port 103.

In an embodiment, in order to accelerate the circulation of the inside and outside air and improve the heat exchange efficiency, a plurality of ventilation holes may be arranged on the housing (i.e., the housing 11 (or the housing 19)) of the heat exchange structure of the condensation device 20. In addition, the condensation device 20 further includes an outer shell sleeved on the outer periphery of the housing, and the fan is installed on the end of the outer shell. A plurality of ventilation holes is arranged on the shell wall of the outer shell to communicate the airflow inside and outside the housing.
