[0017] In some embodiments, the air conditioner further comprises: a fan.

[0041] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] As shown in Figures 1 to 8 The present disclosure provides an air conditioner. The heat exchanger 20 of the air conditioner can not only adapt to the wind speed at different positions of the windward surface, but also avoid the risk of poor drainage on the surface of the heat exchanger 20, and the user experience is better.

[0043] As shown in Figures 1 to 8 The present disclosure provides a heat exchanger 20 for an air conditioner, which comprises 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 arranged on the air conditioner and is arranged in the vertical direction; the upper straight plate section 22 is connected to the upper side of the middle straight plate section 21 by bending; the lower straight plate section 23 is connected to the lower side of the middle straight plate section 21 by bending, and the lower straight plate section 23 and the upper straight plate section 22 are arranged obliquely to the same side of the middle straight plate section 21; wherein the first height h1 of the middle straight plate section 21 is greater than or equal to 30 mm and less than or equal to 70 mm.

[0044] Specifically, the side wall surface of the cabinet 10 is provided with an air inlet 12 and an air outlet 13, and the mounting cavity 11 of the cabinet 10 is provided with an air duct, which is in communication with the air inlet 12 and the air outlet 13 respectively, and the air supply direction of the air duct is defined from the air inlet 12 to the air outlet 13. The heat exchanger 20 is configured as an integrated plate-shaped structure, and the heat exchanger 20 is arranged in the vertical direction as a whole. The heat exchanger 20 includes an upper straight plate section 22, a middle straight plate section 21 and a lower straight plate section 23, and the middle straight plate section 21 is arranged vertically. The upper straight plate section 22 is located above the middle straight plate section 21, and the upper end of the upper straight plate section 22 is inclined to the direction close to the air inlet 12. The lower straight plate section 23 is located below the middle straight plate section 21, and the lower end of the lower straight plate section is inclined to the direction close to the air inlet 12. In this way, the heat exchanger 20 as a whole can form an arch-shaped structure. It can be understood that the air speed at different positions in the air duct is different when the air in the air duct is blown to the heat exchanger 20. Therefore, arranging the heat exchanger 20 as an arch-shaped structure is more conducive to adapting the heat exchanger 20 to the air speed at different positions of the windward surface, thereby improving the heat exchange efficiency of the heat exchanger 20. At the same time, in order to improve the heat exchange area of the heat exchanger 20, the existing straight plate heat exchanger 20 needs to be inclined, which results in that the heat exchanger 20 occupies more space in the horizontal direction as a whole. Therefore, arranging the heat exchanger 20 as an arch-shaped structure can improve the heat exchange area while reducing the space occupied by the heat exchanger 20 in the horizontal direction.

[0045] It can be understood that the air flow in the middle part of the air duct is generally larger, so the first height h1 of the middle straight plate section 21 is greater than or equal to 30 mm and less than or equal to 70 mm, which can better match the air flow in the middle part of the air duct while reserving the installation space of the upper straight plate section 22 and the lower straight plate section 23, thereby improving the heat exchange efficiency, as shown in Figure 2 For example, the first height h1 of the middle straight plate section 21 can be 30 mm, 40 mm, 50 mm, 60 mm or 70 mm.

[0046] As shown in Figure 4As shown 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 to further avoid 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°.

[0047] In practical applications, some existing heat exchangers 20 are configured as split-type structures to accommodate the different air velocities of each part. However, the multiple separate parts of a split-type heat exchanger 20 increase the overall scrap rate during manufacturing, raising production costs. Furthermore, the multiple separate parts of a split-type heat exchanger 20 require individual installation, increasing the installation difficulty. Therefore, this application sets the heat exchanger 20 as an integrated bow-shaped structure, which not only accommodates the different air velocities of each part but also reduces the scrap rate during manufacturing and simplifies installation.

[0048] like Figure 2 As shown, in some embodiments, the height of the heat exchanger 20 is a second height h2; wherein the ratio of the first height h1 to the second height h2 is greater than or equal to 0.15 and less than or equal to 0.4.

[0049] Specifically, the height of heat exchanger 20 refers to the overall height of heat exchanger 20, that is, the vertical distance between the lower end of the lower straight plate section 23 and the upper end of the upper straight plate section 22. Making the ratio of the first height h1 to the second height h2 greater than or equal to 0.15 and less than or equal to 0.4 allows for better matching of airflow velocities in different parts of the duct. For example, the ratio of the first height h1 to the second height h2 can be 0.15, 0.20, 0.25, 0.30, 0.35, or 0.4.

[0050] like Figures 1 to 6 As shown, in some embodiments, the sum of the number of outer sidewalls of the middle straight plate segment 21, the upper straight plate segment 22, and the lower straight plate segment 23 is greater than or equal to 6.

[0051] Specifically, the middle straight plate section 21, the upper straight plate section 22, and the lower straight plate section 23 are each surrounded by a plurality of flat outer side wall surfaces, and the number of outer side wall surfaces of the upper straight plate section 22 and the lower straight plate section 23 is the same. The sum of the number of outer side wall surfaces of the middle straight plate section 21, the upper straight plate section 22, and the lower straight plate section 23 is greater than or equal to 6, that is, the number of outer side wall surfaces of the heat exchanger 20 is greater than or equal to 6. For example, the sum of the number of outer side wall surfaces of the middle straight plate section 21, the upper straight plate section 22, and the lower straight plate section 23 can be 6, 7, 8, 9, or 10. In this way, the surface area of the heat exchanger 20 as a whole can be increased, thereby increasing the contact area of the heat exchanger 20 with the air in the air duct, and further improving the heat exchange efficiency.

[0052] As shown in Figures 1 to 6 , in some embodiments, the first cross section of the middle straight plate section 21 is configured as a rectangle; the second cross section of the upper straight plate section 22 is configured as a parallelogram; and the third cross section of the lower straight plate section 23 is configured as a parallelogram.

[0053] Specifically, configuring the first cross section of the upper straight plate section 22 and the third cross section of the lower straight plate section 23 as parallelograms and configuring the middle straight plate section 21 as a rectangle can make the structure of the heat exchanger 20 as a whole simpler and more convenient for production and processing.

[0054] As shown in Figure 2 , in some embodiments, a circular arc transition structure is provided at the connection between the middle straight plate section 21 and the upper straight plate section 22.

[0055] Specifically, configuring the connection between the upper straight plate section 22 and the middle straight plate section 21 as a circular arc transition structure can enable smooth connection between the upper straight plate section 22 and the middle straight plate section 21, and can further avoid the risk of poor drainage on the surface of the heat exchanger 20.

[0056] As shown in Figure 2 , in some embodiments, a circular arc transition structure is provided at the connection between the middle straight plate section 21 and the lower straight plate section 23.

[0057] Specifically, configuring the connection between the lower straight plate section 23 and the middle straight plate section 21 as a circular arc transition structure can enable smooth connection between the lower straight plate section 23 and the middle straight plate section 21, and can further avoid the risk of poor drainage on the surface of the heat exchanger 20.

[0058] As shown in Figure 2 and Figure 3 , in some embodiments, the heat exchanger 20 includes oppositely arranged windward side wall surface 201 and leeward side wall surface 202; wherein the size and shape of the windward side wall surface 201 correspond to the size and shape of the leeward side wall surface 202.

[0059] Specifically, the size and shape of the windward side wall surface 201 are the same as those of the leeward side wall surface 202, and the windward side wall surface 201 can be overlapped with the leeward side wall surface 202 after being moved in the horizontal direction by a certain distance. It can be understood that the heat exchanger 20 generally includes fins, and the fins are generally continuously cut by shearing or stamping cutting process. Therefore, the shape and size of the windward side wall surface 201 of the heat exchanger 20 are the same as those of the leeward side wall surface 202, which can reduce the generation of processing waste between adjacent two fins, and is beneficial to improve the utilization efficiency of raw materials in the process of manufacturing the heat exchanger 20.

[0060] As shown in Figure 3 , optionally, the thickness of the middle straight plate segment 21 is greater than the thickness of the upper straight plate segment 22, and the thickness of the middle straight plate segment 21 is greater than the thickness of the lower straight plate segment 23.

[0061] Specifically, the thickness of the middle straight plate segment 21 is the first thickness A1, the thickness of the upper straight plate segment 22 is the second thickness A2, and the thickness of the lower straight plate segment 23 is the third thickness A3. Among them, the first thickness A1 is greater than the second thickness A2 and the third thickness A3. For example, the second thickness A2 and the third thickness A3 can be 2 / 3 or 1 / 2 of the first thickness A1.

[0062] It can be understood that when the fan 14 sends air to the heat exchanger 20, the wind speed at the position of the middle straight plate segment 21 is the largest, and the wind speed at the positions of the upper straight plate segment 22 and the lower straight plate segment 23 is smaller than that at the position of the middle straight plate segment 21. Therefore, making the thickness of the middle straight plate segment 21 greater than the thickness of the upper straight plate segment 22 and the lower straight plate segment 23 can make the middle straight plate segment 21 fully heat exchange and ensure that the air speed after flowing through the heat exchanger 20 is more uniform.

[0063] As shown in Figure 4 , optionally, the first plate segment angle α between the upper straight plate segment 22 and the middle straight plate segment 21 is less than or equal to 170°; and the second plate segment angle β between the lower straight plate segment 23 and the middle straight plate segment 21 is less than or equal to 170°.

[0064] Specifically, the first plate segment angle α between the upper straight plate segment 22 and the middle straight plate segment 21 can be set according to the height of the installation cavity. For example, the first plate segment angle α can be 170°, 160°, 150°, 140° or 130°. In this way, the height of the upper straight plate segment 22 as a whole can be reduced while ensuring the heat exchange area of the upper straight plate segment 22. Similarly, the second plate segment angle β can be 170°, 160°, 150°, 140° or 130° to reduce the height of the lower straight plate segment 23.

[0065] In the above embodiments, the height of the upper straight plate section 22 refers to the distance between the horizontal plane where the upper end surface of the upper straight plate section 22 is located and the horizontal plane where the lower end surface is located, and the height of the lower straight plate section 23 refers to the distance between the horizontal plane where the upper end surface of the lower straight plate section 23 is located and the horizontal plane where the lower end surface is located.

[0066] As shown in Figure 5 Optionally, the side edge of the first cross section close to the fan 14 constitutes an upper windward line 221, and the side edge of the third cross section close to the fan 14 constitutes a lower windward line 231. The midpoint of the connecting line segment of the upper end point of the upper windward line 221 and the lower end point of the lower windward line 231 constitutes a reference point F. The first connection included angle e1 between the reference point F and the connecting line of the upper end point and the lower end point of the upper windward line 221 is greater than or equal to 30° and less than or equal to 160°.

[0067] Specifically, the included angle between the reference point F and the connecting line of the upper end point and the lower end point of the upper windward line 221 is the first connection included angle e1. The first connection included angle e1 can be 30°, 60°, 90°, 120° or 160°. In this way, the inclination and length of the upper windward line 221 can be better adapted to the wind speed at the upper straight plate section 22. It can be understood that the side edge of the first cross section away from the fan 14 constitutes an upper leeward line 222. Since the first cross section is a parallelogram, the upper leeward line 222 is parallel to the upper windward line 221, that is, the inclination and length of the upper leeward line 222 are the same as those of the upper windward line 221.

[0068] As shown in Figure 5 Optionally, the second connection included angle e2 between the reference point F and the connecting line of the upper end point and the lower end point of the lower windward line 231 is greater than or equal to 30° and less than or equal to 160°.

[0069] Specifically, the included angle between the reference point F and the connecting line of the upper end point and the lower end point of the lower windward line 231 is the second connection included angle e2. The second connection included angle e2 can be 30°, 60°, 90°, 120° or 160°. In this way, the inclination and length of the lower windward line 231 can be better adapted to the wind speed at the lower straight plate section 23. It can be understood that the side edge of the third cross section away from the fan 14 constitutes a lower leeward line 232. Since the third cross section is a parallelogram, the lower leeward line 232 is parallel to the lower windward line 231, that is, the inclination and length of the lower leeward line 232 are the same as those of the lower windward line 231.

[0070] As shown in Figure 5 Optionally, the side edge of the second cross section close to the fan 14 constitutes a middle windward line 211. The third connection included angle e3 between the reference point F and the connecting line of the upper end point and the lower end point of the middle windward line 211 is greater than or equal to 30° and less than or equal to 160°.

[0071] Specifically, the included angle between the reference point F and the connecting line of the upper end point and the lower end point of the middle windward line 211 is a third connecting included angle e3. The third connecting included angle e3 can be 30°, 60°, 90°, 120° or 160°. In this way, the inclination and length of the middle windward line 211 can be better adapted to the wind speed at the middle straight plate section 21. It can be understood that the side of the second cross section away from the fan 14 constitutes a middle leeward line 212, and since the second cross section is rectangular, the length of the middle leeward line 212 is the same as that of the middle windward line 211.

[0072] As shown in Figures 1 to 8 The air conditioner provided by the present application not only can adapt to the wind speed at different positions of the windward surface, but also can avoid the risk of poor drainage of the surface of the heat exchanger 20, and the user experience is better.

[0073] Specifically, the heat exchanger 20 can be clamped in the installation cavity through the clamping member, or the heat exchanger 20 can be fastened in the installation cavity through the fastening member.

[0074] The air conditioner provided by the present application not only can adapt to the wind speed at different positions of the windward surface, but also can avoid the risk of poor drainage of the surface of the heat exchanger 20, and the user experience is better.

[0075] As shown in Figure 1 In some embodiments, the air conditioner further comprises a fan 14. The fan 14 is arranged in the installation 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 arranged to be inclined towards the fan 14.

[0076] Specifically, the fan 14 is arranged in the air duct, and the fan 14 is located on the side of the heat exchanger 20 close to the air inlet 12. The air outlet end of the fan 14 is communicated with the heat exchanger 20 through the air duct, and the flow direction of the air blown to the heat exchanger 20 is perpendicular to the heat exchanger 20, so as to increase the heat exchange efficiency of the heat exchanger 20 and the air.

[0077] As shown in Figure 6 In some embodiments, the side wall surface of the heat exchanger 20 close to the fan 14 is configured as a windward side wall surface 201, and the side wall surface of the heat exchanger 20 away from the fan 14 is configured as a leeward side wall surface 202; in the case that the size and shape of the windward side wall surface 201 correspond to the size and shape of the leeward side wall surface 202, the air conditioner comprises a plurality of heat exchangers 20; wherein the windward side wall surface 201 and the leeward side wall surface 202 of adjacent heat exchangers 20 are arranged to be in close contact with each other.

[0078] Specifically, the air conditioner is provided with multiple heat exchangers 20, and the multiple heat exchangers 20 are stacked along the air outlet direction of the fan 14, that is, the multiple heat exchangers 20 are uniformly arranged along the horizontal direction, so that the overall heat exchange efficiency of the heat exchangers 20 can be further improved. At the same time, the structure of stacking multiple heat exchangers 20 can reduce the size of a single heat exchanger 20, and is more convenient for processing the heat exchanger 20.

[0079] The foregoing description and drawings suffice to fully enable one skilled in the art to practice the embodiments of the present disclosure.
