[0001] This application relates to the field of household appliance technology, such as a heat exchanger for an air conditioner and an air conditioner. Background Technology
[0002] With societal development, air conditioners have become increasingly widespread. Air conditioners typically incorporate finned tube heat exchangers to exchange heat with the air flowing through them, thus achieving indoor cooling or heating. Traditional heat exchangers often employ split-type or plate-type designs; therefore, uneven airflow on the heat exchanger's front side can lead to decreased heat exchange efficiency.
[0003] In related technologies, in order to improve the heat exchange efficiency of heat exchangers, users generally set the heat exchanger to an arc-shaped structure to adapt to the wind speed at different positions on the windward side of the heat exchanger.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0042] like Figures 1 to 8 As shown in the embodiments of this disclosure, a heat exchanger 20 for an air conditioner and an air conditioner are provided. The heat exchanger 20 of the air conditioner can not only adapt to the wind speed at different positions on its windward side, but also avoid the risk of poor drainage on the surface of the heat exchanger 20, resulting in a better user experience.
[0043] like Figures 1 to 8As shown, this embodiment of the present disclosure provides a heat exchanger 20 for an air conditioner, comprising: a middle straight plate section 21, an upper straight plate section 22, and a lower straight plate section 23. The middle straight plate section 21 is disposed in the air conditioner and has a plurality of heat exchange holes. The upper straight plate section 22 is bent and connected above the middle straight plate section 21 and has a plurality of heat exchange holes. The lower straight plate section 23 is bent and connected below the middle straight plate section 21 and has a plurality of heat exchange holes. The number of heat exchange holes in the upper straight plate section 22 is greater than the number of heat exchange holes in the middle straight plate section 21, and the number of heat exchange holes in the lower straight plate section 23 is greater than the number of heat exchange holes in the middle straight plate section 21.
[0044] Specifically, the air conditioner includes a casing. An air inlet 12 and an air outlet 13 are provided on the side wall of the casing 10. An air duct is provided within the mounting cavity 11 of the casing 10, communicating with both the air inlet 12 and the air outlet 13, and the airflow direction of the duct is limited to from the air inlet 12 to the air outlet 13. The heat exchanger 20 is configured as an integral plate structure, and the entire heat exchanger 20 is arranged vertically. The heat exchanger 20 includes an upper straight plate section 22, a middle straight plate section 21, and a lower straight plate section 23, with the middle straight plate section 21 being vertically arranged. The upper straight plate section 22 is located above the middle straight plate section 21, and its upper end is inclined towards the air inlet 12. The lower straight plate section 23 is located below the middle straight plate section 21, and its lower end is inclined towards the air inlet 12. This allows the heat exchanger 20 to form an overall bow-shaped structure. It is understandable that the air velocity varies at different locations within the air duct when it is blown to the heat exchanger 20. Therefore, designing the heat exchanger 20 as a bow-shaped structure is more conducive to adapting the heat exchanger 20 to the air velocity at different locations on its windward side, thereby improving the heat exchange efficiency of the heat exchanger 20. Simultaneously, to increase the heat exchange area of the heat exchanger 20, the existing straight-plate heat exchanger 20 needs to be tilted, which results in the heat exchanger 20 occupying more space in the horizontal direction. Therefore, designing the heat exchanger 20 as a bow-shaped structure can increase the heat exchange area while reducing the space occupied by the heat exchanger 20 in the horizontal direction.
[0045] In the above embodiment, since the sidewall of the middle straight plate section 21 is a vertical plane, the area of the inclined plane of the heat exchanger 20 as a whole can be reduced, thereby avoiding the risk of poor drainage on the surface of the heat exchanger 20. Meanwhile, the included angle α between the upper straight plate section 22 and the middle straight plate section 21 can be set according to the size of the casing 10. For example, the included angle α between the upper straight plate section 22 and the middle straight plate section 21 can be 100°, 110°, 120°, 130°, or 140°. It is understood that the heat exchanger 20 will produce condensate during air conditioning operation. Therefore, making the included angle α greater than or equal to 100° can increase the slope of the upper straight plate section 22, further avoiding the risk of poor drainage on the surface of the heat exchanger 20. Similarly, the included angle β between the lower straight plate section 23 and the middle straight plate section 21 can be set according to the size of the housing 10. For example, the included angle β between the lower straight plate section 23 and the middle straight plate section 21 can be 100°, 110°, 120°, 130° or 140°.
[0046] Meanwhile, by increasing the number of heat exchange holes in the upper straight plate section 22 and the lower straight plate section 23 compared to the middle straight plate section 21, the heat exchange efficiency of the upper and lower straight plate sections 22 and 23 can be improved while reducing the air resistance of the middle straight plate section 21. This arrangement allows the number of heat exchange holes in the upper, lower, and middle straight plate sections 22 and 23 to better match the corresponding airflow velocities, thereby further improving the overall heat exchange efficiency of the heat exchanger 20.
[0047] In some embodiments, the number of heat exchange holes in the upper straight plate section 22 is greater than or equal to 1.5 times the number of heat exchange holes in the middle straight plate section 21, and less than or equal to 3 times the number of heat exchange holes in the middle straight plate section 21; the number of heat exchange holes in the lower straight plate section 23 is greater than or equal to 1.5 times the number of heat exchange holes in the middle straight plate section 21, and less than or equal to 3 times the number of heat exchange holes in the middle straight plate section 21.
[0048] Specifically, the number of heat exchange holes in the upper straight plate section 22 can be 1.5 times, 2 times, 2.5 times, or 3 times the number of heat exchange holes in the middle straight plate section 21. For example, if the middle straight plate section 21 has 10 heat exchange holes, then the upper straight plate section 22 can have 15, 20, 25, or 30 heat exchange holes. Similarly, the number of heat exchange holes in the lower straight plate section 23 can be 1.5 times, 2 times, 2.5 times, or 3 times the number of heat exchange holes in the middle straight plate section 21. For example, if the middle straight plate section 21 has 10 heat exchange holes, then the lower straight plate section 23 can have 15, 20, 25, or 30 heat exchange holes. This arrangement can further improve the overall heat exchange efficiency of the heat exchanger 20.
[0049] like Figures 2 to 4As shown, in some embodiments, at least some of the heat exchange holes of the upper straight plate section 22 are arranged parallel to the side wall surface of the upper straight plate section 22 to form an upper heat exchange hole group; wherein, the upper straight plate section 22 includes a plurality of upper heat exchange hole groups, and the plurality of upper heat exchange hole groups are arranged parallel to each other along the thickness direction of the upper straight plate section 22.
[0050] Specifically, the upper heat exchange hole group includes multiple heat exchange holes, which are arranged parallel to the side wall surface of the upper straight plate section 22. Simultaneously, the upper straight plate section 22 is provided with multiple upper heat exchange hole groups, which are spaced parallel to each other along the thickness direction of the upper straight plate section 22, i.e., the airflow direction. This arrangement can further improve the heat exchange efficiency of the upper straight plate section 22.
[0051] like Figures 2 to 4 As shown, in some embodiments, the upper straight plate segment 22 includes a first upper heat exchange hole group 223 and a second upper heat exchange hole group 224; wherein the heat exchange holes of the first upper heat exchange hole group 223 and the heat exchange holes of the second upper heat exchange hole group 224 are staggered with each other.
[0052] Specifically, the upper straight plate section 22 includes a first sidewall 221 and a second sidewall 222 disposed opposite to each other. A first upper heat exchange hole group 223 is disposed on the side of the upper straight plate section 22 near the first sidewall 221, and a second upper heat exchange hole group 224 is disposed on the side of the upper straight plate section 22 near the second sidewall 222. Simultaneously, the heat exchange holes of the first upper heat exchange hole group 223 and the heat exchange holes of the second upper heat exchange hole group 224 are staggered, so that the heat exchange holes of the first upper heat exchange hole group 223 are located at the gaps between the heat exchange holes of the second upper heat exchange hole group 224. This arrangement can further improve the heat exchange efficiency of the heat exchanger 20.
[0053] like Figures 2 to 4 As shown, in some embodiments, the first upper heat exchange hole group 223 includes a first heat exchange hole 2231, and the second upper heat exchange hole group 224 includes a second heat exchange hole 2241 and a third heat exchange hole 2242 arranged adjacently, with the second heat exchange hole 2241 and the third heat exchange hole 2242 located on both sides of the first heat exchange hole 2231, respectively; wherein, a first reference line is formed by connecting the second heat exchange hole 2241 and the third heat exchange hole 2242, and a first perpendicular line is formed by drawing a perpendicular line from the first heat exchange hole 2231 to the first reference line, and the first perpendicular line and the first reference line are compared with a first reference point; the distance from the second heat exchange hole 2241 to the first reference point is greater than or equal to 0.8 times the distance from the third heat exchange hole 2242 to the first reference point, and less than or equal to 3 times the distance from the third heat exchange hole 2242 to the first reference point.
[0054] Specifically, the fact that the second heat exchange hole 2241 and the third heat exchange hole 2242 are located on both sides of the first heat exchange hole 2231 means that the second heat exchange hole 2241 and the third heat exchange hole 2242 are located on both sides of the first vertical line, that is, the second heat exchange hole 2241 and the third heat exchange hole 2242 are located on both sides of the first reference point. The distance from the second heat exchange hole 2241 to the first reference point can be 0.8 times, 2 times, 2.5 times, or 3 times the distance from the third heat exchange hole 2242 to the first reference point. For example, when the distance from the third heat exchange hole 2242 to the first reference point is 1 mm, the distance from the second heat exchange hole 2241 to the first reference point is 0.8 mm, 2 mm, 2.5 mm, or 3 mm.
[0055] like Figures 2 to 4 As shown, in some embodiments, the first heat exchange hole 2231 and the second heat exchange hole 2241 are connected to form a second reference line; wherein the first included angle γ1 of the first vertical line and the second reference line is greater than or equal to 25° and less than or equal to 45°.
[0056] Specifically, the first included angle γ1 between the first vertical line and the second reference line can be 25°, 30°, 35°, 40°, or 45°. This setting can further improve the heat exchange efficiency of the upper straight plate section 22.
[0057] like Figures 2 to 4 As shown, in some embodiments, the first heat exchange hole 2231 and the third heat exchange hole 2242 are connected to form a third reference line; wherein the second included angle γ2 between the first vertical line and the third reference line is greater than or equal to 5° and less than or equal to 35°.
[0058] Specifically, the second included angle γ2 between the first vertical line and the third reference line can be 5°, 10°, 15°, 20°, 25°, 30°, or 35°. This setting can further improve the heat exchange efficiency of the upper straight plate section 22.
[0059] like Figures 2 to 4 As shown, in some embodiments, the lower straight plate segment 23 includes a first lower heat exchange hole group and a second lower heat exchange hole group; wherein the heat exchange holes of the first lower heat exchange hole group and the heat exchange holes of the second lower heat exchange hole group are staggered with each other.
[0060] Specifically, the lower straight plate section 23 includes a third side wall and a fourth side wall disposed opposite to each other. A first lower heat exchange hole group is disposed on the side of the lower straight plate section 23 closest to the third side wall, and a second lower heat exchange hole group is disposed on the side of the lower straight plate section 23 closest to the fourth side wall. Simultaneously, the heat exchange holes of the first and second lower heat exchange hole groups are staggered, so that the heat exchange holes of the first lower heat exchange hole group are located at the gaps between the heat exchange holes of the second lower heat exchange hole group. This arrangement can further improve the heat exchange efficiency of the heat exchanger 20.
[0061] like Figures 1 to 8 As shown, this embodiment of the present disclosure also provides an air conditioner including: a housing 10 and the aforementioned heat exchanger 20 for the air conditioner. The housing 10 is provided with a mounting cavity 11; the heat exchanger 20 for the air conditioner is installed in the mounting cavity 11.
[0062] Specifically, the housing 10 is provided with an installation cavity 11, and the side wall of the installation cavity 11 is also provided with snap fasteners such as clips or screws to form a fixing structure 15. The heat exchanger 20 can be snapped into the installation cavity by snap fasteners, or the heat exchanger 20 can be fastened to the installation cavity by fasteners.
[0063] An air conditioner using the heat exchanger 20 provided in this application can not only adapt to the wind speed at different positions on its windward side, but also avoid the risk of poor drainage on the surface of the heat exchanger 20, resulting in a better user experience.
[0064] like Figure 1 As shown, in some embodiments, the air conditioner further includes a fan 14. The fan 14 is disposed in the mounting cavity 11, and the fan 14 is located on one side of the heat exchanger 20; wherein the upper straight plate section 22 and the lower straight plate section 23 of the heat exchanger 20 are inclined toward the fan 14.
[0065] Specifically, the fan 14 is installed inside the air duct, and the fan 14 is located on the side of the heat exchanger 20 near the air inlet 12. The air outlet of the fan 14 is connected to the heat exchanger 20 through the air duct, and the airflow direction blown to the heat exchanger 20 is perpendicular to the heat exchanger 20 to increase the heat exchange efficiency between the heat exchanger 20 and the air.
[0066] like Figure 6 As shown, in some embodiments, the side wall of the heat exchanger 20 near the fan 14 is configured as the windward side wall 201, and the side wall of the heat exchanger 20 away from the fan 14 is configured as the leeward side wall 202; when the size and shape of the windward side wall 201 correspond to the size and shape of the leeward side wall 202, the air conditioner includes a plurality of heat exchangers 20; wherein the windward side wall 201 and leeward side wall 202 of adjacent heat exchangers 20 are fitted together.
[0067] Specifically, the air conditioner is equipped with multiple heat exchangers 20, which are stacked along the air outlet direction of the fan 14, i.e., the multiple heat exchangers 20 are evenly distributed in the horizontal direction, which can further improve the overall heat exchange efficiency of the heat exchangers 20. At the same time, by adopting the structure of stacking multiple heat exchangers 20, the size of a single heat exchanger 20 can be reduced, making it easier to manufacture the heat exchangers 20.
