The present disclosure relates to the field of the air conditioning technology, in particular relates to a heat exchanger fin, a heat exchanger, an indoor unit, and an air conditioner.
At present, a heat exchanger fin commonly used in a heat exchanger of an indoor unit is mostly in a rectangular shape with equal widths or having a partially non-standard shaped structure at both ends of the rectangle, and the pipeline flow paths at the heat exchanger fin are also arranged uniformly according to a rule. However, air flow out of a fan of an indoor unit is generally non-uniform, which easily leads to excess air volume for some regions of the heat exchanger and also results in material waste for some regions, causing low utilization of the heat exchanger and affecting heat exchange efficiency of the air conditioner.
The present disclosure aims to solve at least one problem existing in the prior art or the related art.
For this, one objective of the present disclosure is to provide a heat exchanger fin.
Another objective of the present disclosure is to provide a heat exchanger.
A further objective of the present disclosure is to provide an indoor unit.
A further objective of the present disclosure is to provide an air conditioner.
In order to achieve the above objectives, in one embodiment of the present disclosure provides in embodiments a heat exchanger fin, including: a fin body, including an air outlet contour line arranged at one side and an air inlet contour line arranged at the other side, and provided with refrigerant pipe mounting holes, and a distance between the air inlet contour line and the air outlet contour line of the fin body, on a straight line of a curvature radius of the air outlet contour line of the fin body or on a straight line of a curvature radius of the air inlet contour line of the fin body, gradually decreases from a center to flanks of the heat exchanger fin.
According to embodiments of the present disclosure, the heat exchanger fin includes a fin body; the fin body is provided with refrigerant pipe mounting holes for allowing refrigerant pipes to be mounted; the distance between the air inlet contour line and the air outlet contour line of the fin body, on the straight line of the curvature radius of the air outlet contour line of the fin body or on the straight line of the curvature radius of the air inlet contour line of the fin body, is arranged to gradually decrease from a center to flanks of the heat exchanger fin, and the fin body is of a larger area of the central region than that of the flank region, thus allowing to increase the area of the central region of the fin body where the air volume is high and to reduce the area of the flank region of the fin body where the air volume is low, to improve utilization of the fin body, enhancing heat exchange performance, and reducing energy consumption; at the same time, as the material waste for the region where the air volume is low is reduced, thus facilitating to reduction of manufacture cost.
It should be noted that an air flow out of a fan of a commonly-used air conditioner (particularly an indoor unit) is non-uniform, where the air volume of the central air flow is generally greater than that of the periphery air flow.
In addition, the heat exchanger fin in the above embodiment of the present disclosure may further have the following additional embodiments.
In the above embodiment, the fin body is a one-piece structure. It should be noted that the one-piece structure of the fin body specifically refers to a structure that is integrally formed during processing or manufacturing process. In some examples, forming integrally is achieved by cutting or tailoring a raw material.
In the above embodiment, the fin body is concave in a direction from an air inlet side to an air outlet side, and at least part of the air outlet contour line overlaps with the air inlet contour line after translation.
In this embodiment, the fin body is arranged to be concave in the direction from the air inlet side to the air outlet side, and the fin body is in a curved shape, thus allowing to enlarge a distance between the central region of the fin body and an outlet where the air flow comes from, to reduce air pressure on the heat exchanger fin; and at least part of the air outlet contour line of the fin body is arranged to overlap with the air inlet contour line after translation, to facilitate to tailoring of the fin body during processing, reduce waste material during processing and accordingly reduce manufacture cost. It would be understood that the fin body is shaped and tailored from an entire piece of raw material during manufacture and processing, therefore reducing the distance between two fins across the entire piece of raw material increases material utilization.
In the above embodiment, a first end and a second end of the air inlet contour line are connected to the air outlet contour line respectively; a maximum distance point is within ⅕ to ⅘ of the air inlet contour line along a direction from the first end to the second end of the air inlet contour line.
In this embodiment, the first end and the second end of the air inlet contour line are arranged to connect to the air outlet contour line respectively, forming a complete outer contour of the fin body; the maximum distance point is within ⅕ to ⅘ of the air inlet contour line along a direction from the first end to the second end of the air inlet contour line, so that the maximum distance is away from the first end and the second end (i.e., the maximum distance is located within the central region of the fin body, thus allowing a region with the largest area of the fin body to correspond to air flow in higher air volume, to improve utilization of the heat exchanger fin.
In the above embodiment, a straight line corresponding to the maximum distance extends along an air inlet direction for the heat exchanger fin.
In this embodiment, the straight line corresponding to the maximum distance is arranged to extend along the air inlet direction for the heat exchanger fin, so that the extending direction of the fin body is consistent with the air inlet direction, to increase a contact area for the fin body and the inlet air flow, thus facilitating to improving heat exchange efficiency. It should be noted that the air inlet direction is an overall direction of a movement trend of the inlet air flow. There is a maximum distance between the air inlet contour line and the air outlet contour line of the fin body on the straight line of the curvature radius of the air outlet contour line of the fin body or on the straight line of the curvature radius of the air inlet contour line of the fin body, where the straight line where the maximum distance is located is the straight line corresponding to the maximum distance.
In the above embodiment, the fin body is symmetrical relative to the straight line corresponding to the maximum distance.
In this embodiment, the fin body is arranged to be symmetrical relative to the straight line corresponding to the maximum distance, so that two parts of the fin body which are divided by the straight line corresponding to the maximum distance are in similar shapes, thus providing the heat exchanger including the heat exchanger fin with uniform heat exchange performance, and facilitating to tailoring the heat exchanger fin during processing.
In the above embodiment, a length of the air inlet contour line at one side of the straight line corresponding to the maximum distance is greater than a length of the air inlet contour line at the other side of the straight line corresponding to the maximum distance.
In this embodiment, the length of the air inlet contour line at one side of the straight line corresponding to the maximum distance is arranged to be greater than the length of the air inlet contour line at the other side of the straight line corresponding to the maximum distance, so that the fin body is in an essential asymmetric shape, thus allowing to increase an area of a region of the fin body where the air volume is high and to reduce an area of a region of the fin body where the air volume is low, which are arranged in accordance with different air volumes of the inlet air flow, to improve utilization of the heat exchanger fin. It would be understood that the inlet air flow is non-uniform, where the air volume within the air flow is not necessarily exactly symmetric.
In the above embodiment, the air outlet contour line includes five arc segments connected in sequence, and the adjacent arc segments are of gradually decreasing curvatures from the center to the flanks of the heat exchanger fin.
In this embodiment, the air outlet contour line is arranged to include five arc segments connected in sequence, and the adjacent arc segments are arranged to be of gradually decreasing curvatures from the center to the flanks of the heat exchanger fin, so that different parts of the fin body are provided in different shapes by varying curvatures of different arc segments, thus facilitating to shaping and tailoring of the fin body during processing in accordance with the air volume of the inlet air flow.
In the above embodiment, a plane where the air inlet direction for the fin body is located is a first plane, and a plane which is perpendicular to the first plane is a second plane; and the fin body is of a larger projection size on the second plane than that on the first plane.
In this embodiment, a plane where the air inlet direction for the fin body is located is arranged to be a first plane, and a plane which is perpendicular to the first plane is arranged to be a second plane; and the fin body is arranged to be of a larger projection size on the second plane than that on the first plane, so that the fin body can be provided with an increased angle between the air inlet contour line and the air outlet contour line, thus facilitating to increasing an contact area between the refrigerant pipe arranged at the heat exchanger fin and the inlet air flow, to improve heat exchange efficiency.
In the above embodiment, the fin body is of a larger projection size on the second plane at one side of the straight line corresponding to the maximum distance than that on the second plane at the other side of the straight line corresponding to the maximum distance.
In this embodiment, the fin body is arranged to be of a larger projection size on the second plane at one side of the straight line corresponding to the maximum distance than that on the second plane at the other side of the straight line corresponding to the maximum distance, so that the fin body is provided in an asymmetric shape, and two parts of the fin body are provided with different projection sizes on the second plane (i.e., two parts of the fin body, which are divided by the straight line corresponding to the maximum distance, are of different sizes on a plane perpendicular to the air inlet direction), thus allowing a region with a larger size of the fin body to correspond to air flow in higher air volume and allowing a region with a smaller size of the fin body to correspond to the air flow in lower air volume, which are arranged in accordance with different air volumes of the inlet air flow, to improve utilization of the fin body and increasing heat exchange efficiency.
In the above embodiment, the fin body is of a larger projection size on the first plane at one side of the straight line corresponding to the maximum distance than that on the first plane at the other side of the straight line corresponding to the maximum distance.
In this embodiment, the fin body is arranged to be of a larger projection size on the first plane at one side of the straight line corresponding to the maximum distance than that on the first plane at the other side of the straight line corresponding to the maximum distance, so that the fin body is provided in an asymmetric shape, and two parts of the fin body are provided with different projection sizes on the first plane where the air inlet direction is located, thus allowing a region with a larger size of the fin body to correspond to air flow in higher air volume and allowing a region with a smaller size of the fin body to correspond to the air flow in lower air volume, which are arranged in accordance with different air volumes of the inlet air flow, to improve utilization of the fin body and increasing heat exchange efficiency.
In the above embodiment, the heat exchanger fin is formed as an equidistant region at the center, and the distance between the air inlet contour line and the air outlet contour line is equal within the equidistant region.
In this embodiment, the heat exchanger fin is arranged to be formed as an equidistant region at the center, and the distance between the air inlet contour line and the air outlet contour line is arranged to be equal within the equidistant region, to increase the area of the region of the fin body corresponding to the inlet air flow in higher air volume, thus improving utilization of the fin body and increasing heat exchange efficiency. It would be understood that the air volume of the central air flow is same or almost same with extremely low variation.
In the above embodiment, the air inlet contour line and the air outlet contour line within the equidistant region are any one or any combination of an arc and a straight line.
In this embodiment, the air inlet contour line and the air outlet contour line within the equidistant region may be in various shapes, including any one or any combination of an arc and a straight line, where the straight line is convenient for tailing of the fin body during processing, while the arc allows the air inlet contour line and the air outlet contour line streamlined, which is beneficial to reduce the wind resistance and make the air flow more smoothly.
In the above embodiment, the number of the refrigerant pipe mounting holes is gradually decreased from the center to the flanks of the heat exchanger fin.
In this embodiment, the number of the refrigerant pipe mounting holes is arranged to gradually decrease from the center to the flanks of the heat exchanger fin, so that the region of the fin body corresponding to the inlet air flow in higher air volume is provided with more refrigerant pipes, and the region of the fin body corresponding to the inlet air flow in low air volume is provided with fewer refrigerant pipes, fully utilizing the inlet air flow and improving heat exchange efficiency, and facilitating to reducing the area of the region of the fin body corresponding to the inlet air flow in low air volume to save material.
In the above embodiment, a distance between adjacent refrigerant pipe mounting holes is positively correlated with a diameter of the refrigerant pipe mounting hole.
In this embodiment, in order to reduce mutual influence between the refrigerant pipes, adjacent refrigerant pipes are maintained at a distance. As the total area of the fin body is limited, the distance between adjacent refrigerant pipe mounting holes is arranged to be positively correlated with the diameter of the refrigerant pipe mounting hole, to arrange the refrigerant pipes in a reasonable way within the limited space. In other words, the greater a pipe diameter of the refrigerant pipe is, the farther the distance between adjacent refrigerant pipes is; and the smaller the pipe diameter of the refrigerant pipe is, the nearer between adjacent refrigerant pipes, to improve utilization of the heat exchanger fin.
In the above embodiment, an inner diameter of the refrigerant pipe mounting hole is gradually decreased from the center to the flanks of the heat exchanger fin.
In this embodiment, the inner diameter of the refrigerant pipe mounting hole is arranged to gradually decrease from the center to the flanks of the heat exchanger fin, so that the refrigerant pipes are of different pipe diameters depending on different positions where the refrigerant pipe is located at the fin body, thus allowing a refrigerant pipe with a larger pipe diameter to be arranged at the region of the fin body where the area is larger, and allowing a refrigerant pipe with a smaller pipe diameter to be arranged at the region of the fin body where the area is lower, to facility improving of the utilization of the heat exchange fin, enhancing heat exchange performance, and reducing energy consumption; at the same time, as the material waste for the region where the air volume is low is reduced, thus facilitating to reduction of manufacture cost.
The fin body may be a one-piece structure, or may also be a split combined structure. It should be note that the one-piece structure of the fin body specifically refers to a structure that is integrally formed during processing or manufacturing process. In some examples, forming integrally is achieved by cutting or tailoring a raw material.
In the above embodiment, the distance between the air inlet contour line and the air outlet contour line of the fin body corresponding to the refrigerant pipe mounting hole is positively correlated with an internal diameter of each refrigerant pipe mounting hole, on a straight line of a curvature radius of the air outlet contour line of the fin body or on a straight line of a curvature radius of the air inlet contour line of the fin body.
In this embodiment, the distance between the air inlet contour line and the air outlet contour line of the fin body corresponding to the refrigerant pipe mounting hole is arranged to be positively correlated with an internal diameter of each refrigerant pipe mounting hole on the straight line of the curvature radius of the air outlet contour line of the fin body or on the straight line of the curvature radius of the air inlet contour line of the fin body. In other words, the greater the distance between the air inlet contour line and the air outlet contour line of the fin body is, the larger the internal diameter of the corresponding refrigerant pipe mounting hole is, so that the pipe diameter of the refrigerant pipe to be mounted in the refrigerant pipe mount hole is accordingly larger; vice versa, the smaller the distance between the air inlet contour line and the air outlet contour line of the fin body is, the smaller the internal diameter of the corresponding refrigerant pipe mounting hole is, so that the pipe diameter of the refrigerant pipe to be mounted in the refrigerant pipe mount hole is accordingly smaller, thus fully utilizing the fin body depending on the areas of different regions, arranging matching refrigerant pipe mounting holes for the corresponding part, to improve utilization of the heat exchanger fin, enhancing heat exchange performance and reducing energy consumption when the heat exchanger fin is mounted with the refrigerant pipes matching with the refrigerant pipe mounting holes.
In the above embodiment, an internal diameter of each refrigerant pipe mounting hole is linear-positively correlated with a distance of circle centers between any two adjacent refrigerant pipe mounting holes, on a straight line of a curvature radius of the air outlet contour line of the fin body or on a straight line of a curvature radius of the air inlet contour line of the fin body.
In this embodiment, the internal diameter of each refrigerant pipe mounting hole is arranged to be linear-positively correlated with a distance of circle centers between any two adjacent refrigerant pipe mounting holes, on the straight line of the curvature radius of the air outlet contour line of the fin body or on the straight line of the curvature radius of the air inlet contour line of the fin body, so that the internal diameter of the refrigerant pipe mounting hole is arranged depending on the distance of circle centers between any two adjacent refrigerant pipe mounting holes. In other words, the greater the distance of circle centers between two adjacent refrigerant pipe mounting holes is, the larger the internal diameter of the refrigerant pipe mounting hole is; vice versa, the smaller the distance of circle centers between two adjacent refrigerant pipe mounting holes is, the smaller the internal diameter of the refrigerant pipe mounting hole is, so that adjacent refrigerant pipe mounting holes are maintained at a proper distance of circle centers, to improve utilization of the heat exchanger fin, enhancing heat exchange performance and reducing energy consumption when the heat exchanger fin is mounted with the refrigerant pipes matching with the refrigerant pipe mounting holes. It would be understood that an over large distance of circle centers between adjacent refrigerant pipe mounting holes will easily lead to insufficient heat exchange for the refrigerant pipe that influences the heat exchange efficiency; an over close distance of circle centers between adjacent refrigerant pipe mounting holes will easily lead to material waste for the refrigerant pipe and also lead to an over small area of a region of the fin body between two adjacent refrigerant pipe mounting holes, resulting in easy break and thus adversely affecting reliability of the heat exchanger fin.
