[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 8 As 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; the upper straight plate section 22 is bent and connected above the middle straight plate section 21, and an upper connecting bridge plate group 212 is disposed at the connection between the middle straight plate section 21 and the upper straight plate section 22; the lower straight plate section 23 is bent and connected below the middle straight plate section 21, and a lower connecting bridge plate group 213 is disposed at the connection between the middle straight plate section 21 and the lower straight plate section 23; wherein, the upper connecting bridge plate group 212 and the lower connecting bridge plate group 213 are respectively provided with multiple connecting bridge plates.
[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] like Figure 3 and Figure 4As shown, it can be understood that setting an open-bridge structure in heat exchanger 20 can not only increase the heat exchange area, reduce thermal resistance, and improve the heat transfer temperature difference, but also improve the fluid flow state, reduce fluid resistance, and enhance convective heat transfer. Meanwhile, since the wind speed at the middle straight plate section 21 is generally higher, setting an upper connecting bridge plate group 212 at the connection between the upper straight plate section 22 and the middle straight plate section 21, and setting a lower connecting bridge plate group 213 at the connection between the lower straight plate section 23 and the middle straight plate section 21, can further enhance the trailing edge heat transfer of the middle straight plate section 21.
[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the upper connecting bridge plate group 212 is provided with two connecting bridge plates; the lower connecting bridge plate group 213 is provided with two connecting bridge plates.
[0048] Specifically, by setting two connecting bridge plates in the upper connecting bridge plate group 212 and two connecting bridge plates in the lower connecting bridge plate group 213, the air resistance of the middle straight plate section 21 can be reduced while ensuring heat exchange efficiency, and the drainage effect at the bend of the heat exchanger 20 can be improved.
[0049] like Figure 3 and Figure 4 As shown, in some embodiments, the upper straight plate section 22 is provided with a plurality of heat exchange holes 24 and a plurality of upper bridge plate groups 221, and the plurality of upper bridge plate groups 221 are respectively disposed at the gaps between the plurality of heat exchange holes 24; the middle straight plate section 21 is provided with a plurality of heat exchange holes 24 and a plurality of middle bridge plate groups 211, and the plurality of middle bridge plate groups 211 are respectively disposed at the gaps between the plurality of heat exchange holes 24; the lower straight plate section 23 is provided with a plurality of heat exchange holes 24 and a plurality of lower bridge plate groups 231, and the plurality of lower bridge plate groups 231 are respectively disposed at the gaps between the plurality of heat exchange holes 24.
[0050] Specifically, the upper straight plate section 22 is provided with multiple heat exchange holes 24 for installing heat exchange pipes. At least one upper bridge plate assembly 221 is provided between any two heat exchange holes 24 in the upper straight plate section 22 to increase the heat exchange efficiency of the upper straight plate section 22. Similarly, the middle straight plate section 21 is provided with multiple heat exchange holes 24, and at least one middle bridge plate assembly 211 is provided between any two heat exchange holes 24 in the middle straight plate section 21 to increase the heat exchange efficiency of the middle straight plate section 21; the lower straight plate section 23 is provided with multiple heat exchange holes 24, and at least one lower bridge plate assembly 231 is provided between any two heat exchange holes 24 in the lower straight plate section 23 to increase the heat exchange efficiency of the lower straight plate section 23.

[0052] Specifically, the width and height of the upper bridge plate can be set according to the user's actual needs to make the upper bridge plate more suitable for the airflow velocity at the corresponding position, thereby further improving the heat exchange efficiency of the upper straight plate section 22. For example, the width of the upper bridge plate can be 1mm, 1.1mm, 1.2mm or 1.3mm, and the height of the upper bridge plate can be 0.5mm, 0.6mm or 0.7mm.
[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the central bridge piece group 211 is provided with a plurality of central bridge pieces; the width of the central bridge piece is greater than or equal to 1.6 mm and less than or equal to 1.8 mm; the height of the central bridge piece is greater than or equal to 0.5 mm and less than or equal to 0.7 mm.
[0054] Specifically, the width and height of the central bridge plate can be set according to the user's actual needs to make the central bridge plate more suitable for the airflow velocity at the corresponding position, thereby further improving the heat exchange efficiency of the central straight plate section 21. For example, the width of the central bridge plate can be 1.6mm, 1.7mm or 1.8mm, and the height of the central bridge plate can be 0.5mm, 0.6mm or 0.7mm.
[0055] like Figure 3 and Figure 4 As shown, in some embodiments, the lower bridge plate group 231 is provided with a plurality of lower bridge plates; the width of the lower bridge plate is greater than or equal to 1.6 mm and less than or equal to 1.8 mm; the height of the lower bridge plate is greater than or equal to 0.5 mm and less than or equal to 0.7 mm.
[0056] Specifically, the width and height of the lower bridge plate can be set according to the user's actual needs to make the lower bridge plate more suitable for the airflow velocity at the corresponding position, thereby further improving the heat exchange efficiency of the lower straight plate section 23. For example, the width of the lower bridge plate can be 1.6mm, 1.7mm or 1.8mm, and the height of the lower bridge plate can be 0.5mm, 0.6mm or 0.7mm.
[0057] like Figure 3 and Figure 4 As shown, in some embodiments, the upper bridge plate group 221 is provided with 4 upper bridge plates; the middle bridge plate group 211 is provided with 2 upper bridge plates; and the lower bridge plate group 231 is provided with 3 upper bridge plates.
[0058] Specifically, the upper straight plate section 22 is provided with multiple upper bridge plate groups 221, and each upper bridge plate group 221 is provided with 4 upper bridge plates to improve the heat exchange efficiency of the upper straight plate section 22. The middle straight plate section 21 is provided with multiple middle bridge plate groups 211, and each middle bridge plate group 211 is provided with 2 middle bridge plates to reduce the air resistance of the middle straight plate section 21. Similarly, the lower straight plate section 23 is provided with multiple lower bridge plate groups 231, and each lower bridge plate group 231 is provided with 3 lower bridge plates to improve the heat exchange efficiency of the lower straight plate section 23.
[0059] like Figure 3 As shown, optionally, the middle straight plate section 21, the upper straight plate section 22 and / or the lower straight plate section 23 are also provided with heat transfer structures such as convex bulges 25.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] 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.
[0064] 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.
[0065] like Figure 6As 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.
[0066] 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.
