[0001] The present application relates to the technical field of household appliances, for example to a heat exchanger for an air conditioner and an air conditioner. BACKGROUND
[0002] With the development of society, the popularity of air conditioners is also increasing. In the air conditioner, a finned tube heat exchanger is arranged to exchange heat with the air flowing therethrough to achieve cooling or heating of the indoor. The conventional heat exchanger is mostly a split heat exchanger or a straight plate heat exchanger, so if the wind speed on the windward surface of the heat exchanger is not uniform, the heat exchange efficiency will be reduced.

The cross section of the lower straight plate section comprises a lower windward line on the windward side and a lower leeward line on the leeward side. The extension line of the upper leeward line and the extension line of the lower leeward line are compared to a first intersection point M1.

The first included angle θ1 between the first reference line X1 and the second reference line X2 is greater than or equal to 80° and less than or equal to 140°.
[0012] In some embodiments, the middle straight plate section further comprises a middle windward line on the windward side. The midpoint of the middle windward line is a second midpoint N2. The straight line formed by the first midpoint N1 and the second midpoint N2 forms a third reference line X3.

[0015] In some embodiments, the fifth included angle θ5 between the upper windward line and the lower windward line is greater than or equal to 60° and less than or equal to 120°.
[0016] The air conditioner provided by the embodiment of the present disclosure comprises a shell and the heat exchanger for the air conditioner. The shell is provided with a mounting cavity, and the heat exchanger for the air conditioner is mounted in the mounting cavity.
[0017] In some embodiments, the air conditioner further comprises a fan. The fan is arranged in the mounting cavity, and the fan is located at one side of the heat exchanger. The upper straight plate section and the lower straight plate section of the heat exchanger are arranged to be inclined towards the fan.
[0018] In some embodiments, the side wall surface of the heat exchanger on the side close to the fan is configured as a windward side wall surface, and the side wall surface of the heat exchanger on the side away from the fan is configured as a leeward side wall surface. In the case where the size and shape of the windward side wall surface correspond to the size and shape of the leeward side wall surface, the air conditioner comprises a plurality of heat exchangers. The windward side wall surface and the leeward side wall surface of adjacent heat exchangers are arranged to be in close contact with each other.
[0019] The heat exchanger for the air conditioner and the air conditioner provided by the embodiment of the present disclosure can achieve the following technical effects:
[0020] The heat exchanger for the air conditioner provided by the embodiment of the present disclosure comprises a middle straight plate section, an upper straight plate section and a lower straight plate section. The middle straight plate section is arranged in the air conditioner. The upper straight plate section is connected to the upper side of the middle straight plate section by bending. The upper straight plate section is arranged to be inclined towards the windward side, and the cross section of the upper straight plate section comprises an upper windward line on the windward side and an upper leeward line on the leeward side. The lower straight plate section is connected to the lower side of the middle straight plate section by bending. The lower straight plate section is arranged to be inclined towards the windward side, and the cross section of the lower straight plate section comprises a lower windward line on the windward side and a lower leeward line on the leeward side. The extension line of the upper leeward line and the extension line of the lower leeward line are compared with the first intersection point M1, the extension line of the upper windward line and the extension line of the lower windward line are compared with the second intersection point M2, and the first intersection point M1 and the second intersection point M2 are on the same horizontal line. In this way, when the fan blows air, the upper straight plate section, the middle straight plate section and the lower straight plate section can respectively adapt to the wind speed on their windward sides, so as to ensure the heat exchange efficiency of the heat exchanger. At the same time, since the side wall surface of the middle straight plate section is a vertical plane, the area of the inclined plane of the heat exchanger as a whole can be reduced. In this way, the heat exchanger can not only 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, and the user experience is better.

[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 Figures 1 to 8 shown, the embodiments of the present disclosure provide a heat exchanger 20 for an air conditioner and 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 Figures 1 to 8 shown, the heat exchanger 20 for the air conditioner provided by the embodiment of the present disclosure 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 in the air conditioner; the upper straight plate section 22 is connected to the upper side of the middle straight plate section 21 in a bent manner, the upper straight plate section 22 is arranged in an inclined manner towards the windward side, and the cross section of the upper straight plate section 22 comprises an upper windward line 221 located on the windward side and an upper leeward line 222 located on the leeward side; the lower straight plate section 23 is connected to the lower side of the middle straight plate section 21 in a bent manner, the lower straight plate section 23 is arranged in an inclined manner towards the windward side, and the cross section of the lower straight plate section 23 comprises a lower windward line 231 located on the windward side and a lower leeward line 232 located on the leeward side; wherein the extension line of the upper leeward line 222 and the extension line of the lower leeward line 232 are compared to the first intersection point M1, the extension line of the upper windward line 221 and the extension line of the lower windward line 231 are compared to the second intersection point M2, and the first intersection point M1 and the second intersection point M2 are on the same horizontal line.
[0044] Specifically, the air conditioner comprises a shell. The side wall surface of the shell 10 is provided with an air inlet 12 and an air outlet 13, and the mounting cavity 11 of the shell 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 as from the air inlet 12 to the air outlet 13. The heat exchanger 20 is configured as an integrated plate structure, and the heat exchanger 20 is arranged in the vertical direction as a whole. The heat exchanger 20 comprises 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 arranged in an inclined manner towards 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 arranged in an inclined manner towards the direction close to the air inlet 12. In this way, the heat exchanger 20 as a whole constitutes a arch-shaped structure. It can be understood that the air in the air duct is blown to the heat exchanger 20 at different speeds at different positions. Therefore, arranging the heat exchanger 20 as a whole in an arch-shaped structure is more conducive to adapting the wind speed at different positions of the windward surface of the heat exchanger 20, 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 type heat exchanger 20 needs to be arranged in an inclined manner, which results in that the heat exchanger 20 as a whole occupies more space in the horizontal direction. Therefore, arranging the heat exchanger 20 as a whole in 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 rates in the upper, middle and lower parts of the general air duct are different, so that the first intersection M1 and the second intersection M2 are on the same horizontal line, which can make the upper windward line 221 and the upper leeward line 222 more suitable for the air flow rate in the upper part of the air duct, and make the lower windward line 231 and the lower leeward line 232 more suitable for the air flow rate in the lower part of the air duct, thereby improving the heat exchange efficiency.
[0046] In the above embodiment, since the side wall surface 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. At the same time, the first plate section angle a between the upper straight plate section 22 and the middle straight plate section 21 can be set according to the size of the cabinet 10, for example, the first plate section angle a between the upper straight plate section 22 and the middle straight plate section 21 can be 100°, 110°, 120°, 130° or 140°. It can be understood that during the operation of the air conditioner, the heat exchanger 20 will generate condensate water. Therefore, making the first plate section angle a 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 second plate section 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 cabinet 10, for example, the second plate section 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 actual application, the existing part of the heat exchanger 20 is also configured as a split structure to match the wind speed of different parts. However, the multiple split parts of the split heat exchanger 20 increase the waste rate of the heat exchanger 20 as a whole during production and processing, thereby increasing the production cost. At the same time, the multiple split parts of the split heat exchanger 20 need to be installed separately, thereby increasing the installation difficulty of the heat exchanger 20. Therefore, the heat exchanger 20 is set as an integrated arch-shaped structure, which can not only match the wind speed of different parts, but also reduce the waste rate of the heat exchanger 20 during production and processing, and reduce the installation difficulty of the heat exchanger 20.
[0048] As shown in FIGS. Figure 2 and Figure 3 In some embodiments, the cross section of the middle straight plate section 21 includes a middle leeward line 212 located at the leeward side, and the middle point of the middle leeward line 212 is a first middle point N1; wherein the first middle point N1, the first intersection M1 and the second intersection M2 are on the same horizontal line, and the first middle point N1 is located between the first intersection M1 and the second intersection M2.
[0049] Specifically, the first midpoint N1 is on the same horizontal line with the first intersection M1 and the second intersection M2, which can make the length and shape of the upper straight plate segment 22, the middle straight plate segment 21 and the lower straight plate segment 23 more suitable for the air flow rate at the corresponding position in the air duct. Meanwhile, the first midpoint N1 is between the first intersection M1 and the second intersection M2, which can make the included angle between the upper straight plate segment 22 and the middle straight plate segment 21, and the included angle between the lower straight plate segment 23 and the middle straight plate segment 21 more suitable for the air flow rate at the corresponding position.
[0050] As shown in Figure 2 and Figure 3 , in some embodiments, the upper end point of the upper leeward line 222 is a first end point G1, and the line segment between the first end point G1 and the first midpoint N1 constitutes a first reference line X1; the lower end point of the lower leeward line 232 is a second end point G2; the line segment between the second end point G2 and the first midpoint N1 constitutes a second reference line X2; wherein the first included angle θ1 between the first reference line X1 and the second reference line X2 is greater than or equal to 80° and less than or equal to 140°.
[0051] Specifically, by adjusting the first included angle θ1 between the first reference line X1 and the second reference line X2, the angle and distance between the upper end point of the upper leeward line 222 and the lower end point of the lower leeward line 232 are adjusted, and then the height of the heat exchanger 20 as a whole is adjusted. For example, the first included angle θ1 can be 80°, 90°, 100°, 110°, 120°, 130° or 140°.
[0052] As shown in Figure 2 and Figure 3 , in some embodiments, the middle straight plate segment 21 further includes a middle windward line 211 on the windward side, and the midpoint of the middle windward line 211 is a second midpoint N2; the straight line formed by connecting the first midpoint N1 and the second midpoint N2 constitutes a third reference line X3; wherein the second included angle θ2 between the third reference line X3 and the upper windward line 221 is greater than or equal to 20° and less than or equal to 80°.
[0053] Specifically, by adjusting the second included angle θ2 between the upper windward line 221 and the third reference line X3, the angle of the upper straight plate segment 22 tilting to the windward side can be adjusted, and then the width and height of the upper half of the heat exchanger 20 are adjusted. For example, the second included angle θ2 can be 20°, 30°, 40°, 50°, 60°, 70° or 80°.
[0054] As shown in Figure 2 and Figure 3 , in some embodiments, the third included angle θ3 between the third reference line X3 and the lower windward line 231 is greater than or equal to 20° and less than or equal to 65°.
[0055] Specifically, by adjusting the third included angle θ3 between the lower windward line 231 and the third reference line X3, the angle of the lower straight plate segment 23 being inclined to the windward side can be adjusted, and further the width and height of the lower half of the heat exchanger 20 can be adjusted. For example, the third included angle θ3 can be 20°, 30°, 40°, 50°, 60°, or 65°.
[0056] In practical applications, the second included angle θ2 and the third included angle θ3 can be the same or different, and the user can determine the second included angle θ2 and the third included angle θ3 according to actual needs. For example, when the second included angle θ2 is 20°, the third included angle θ3 can be 20° or 65°; similarly, when the second included angle θ2 is 80°, the third included angle θ3 can be 20° or 65°.
[0057] As shown in Figure 2 and Figure 3 In some embodiments, the fourth included angle θ4 between the upper leeward line 222 and the lower leeward line 232 is greater than or equal to 60° and less than or equal to 120°.
[0058] Specifically, the fourth included angle θ4 between the extension line of the upper leeward line 222 and the extension line of the lower leeward line 232 is greater than or equal to 60° and less than or equal to 120° compared to the first intersection point M1. For example, the fourth included angle θ4 can be 60°, 70°, 80°, 90°, 100°, 110°, or 120°. In this way, by adjusting the fourth included angle θ4, the inclination angle of the upper leeward line 222 and the lower leeward line 232 can be adjusted, and further the maximum height and width of the heat exchanger 20 can be adjusted.
[0059] As shown in Figure 2 and Figure 3 In some embodiments, the fifth included angle θ5 between the upper windward line 221 and the lower windward line 231 is greater than or equal to 60° and less than or equal to 120°.
[0060] Specifically, the fifth included angle θ5 between the extension line of the upper windward line 221 and the extension line of the lower windward line 231 is greater than or equal to 60° and less than or equal to 120° compared to the second intersection point M2. For example, the fifth included angle θ5 can be 60°, 70°, 80°, 90°, 100°, 110°, or 120°. In this way, by adjusting the fifth included angle θ5, the inclination angle of the upper windward line 221 and the lower windward line 231 can be adjusted, and further the spacing between the upper straight plate segment 22 and the lower straight plate segment 23 can be adjusted.
[0061] In the above embodiment, the user can also adjust the fourth included angle θ4 and the fifth included angle θ5, and further adjust the contour shape of the upper straight plate segment 22 and the lower straight plate segment 23, to further adapt to the air flow rate at different positions in the air duct.
[0062] 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.
[0063] Specifically, the thickness of the middle straight plate segment 21 is a first thickness A1, the thickness of the upper straight plate segment 22 is a second thickness A2, and the thickness of the lower straight plate segment 23 is a third thickness A3. 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.
[0064] It can be understood that when the fan 14 supplies air to the heat exchanger 20, the air speed at the position of the middle straight plate segment 21 is the largest, and the air 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 thickness of the lower straight plate segment 23 can make the middle straight plate segment 21 sufficiently heat-exchanged, and ensure that the air speed after flowing through the heat exchanger 20 is more uniform.
[0065] As shown in Figure 4 Optionally, the first plate segment included 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 included angle β between the lower straight plate segment 23 and the middle straight plate segment 21 is less than or equal to 170°.
[0066] Specifically, the first plate segment included 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 included 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 included angle β can be 170°, 160°, 150°, 140°, or 130°, to reduce the height of the lower straight plate segment 23.
[0067] In the above embodiment, the height of the upper straight plate segment 22 refers to the distance between the horizontal plane where the upper end surface of the upper straight plate segment 22 is located and the horizontal plane where the lower end surface is located, and the height of the lower straight plate segment 23 refers to the distance between the horizontal plane where the upper end surface of the lower straight plate segment 23 is located and the horizontal plane where the lower end surface is located.
[0068] As shown in Figure 5As shown, optionally, the side of the first cross section near the fan 14 forms the upper windward line 221, and the side of the third cross section near the fan 14 forms the lower windward line 231. The midpoint of the line segment connecting the upper endpoint of the upper windward line 221 and the lower endpoint of the lower windward line 231 forms the reference F. The first connection angle e1 between the reference point F and the line connecting the upper endpoint and the lower endpoint of the upper windward line 221 is greater than or equal to 30° and less than or equal to 160°.
[0069] Specifically, the angle between the reference point F and the line connecting the upper and lower endpoints of the upper windward line 221 is the first connecting angle e1. The first connecting angle e1 can be 30°, 60°, 90°, 120°, or 160°. This allows the inclination and length of the upper windward line 221 to better match the wind speed at the upper straight section 22. It can be understood that the side of the first cross-section away from the fan 14 forms the 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.
[0070] like Figure 5 As shown, optionally, the second connection angle e2 between the reference point F and the line connecting the upper and lower endpoints of the lower windward line 231 is greater than or equal to 30° and less than or equal to 160°.
[0071] Specifically, the angle between the reference point F and the line connecting the upper and lower endpoints of the lower windward line 231 is the second connecting angle e2. The second connecting angle e2 can be 30°, 60°, 90°, 120°, or 160°. This allows the inclination and length of the lower windward line 231 to better match the wind speed at the lower straight section 23. It can be understood that the side of the third cross-section away from the fan 14 forms the 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.
[0072] like Figure 5 As shown, optionally, the side of the second cross section near the fan 14 forms the central windward line 211; wherein, the third connection angle e3 between the reference point F and the connecting lines of the upper and lower endpoints of the central windward line 211 is greater than or equal to 30° and less than or equal to 160°.
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] As shown in Figure 1 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.
[0078] 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.
[0079] 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.
[0080] 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.
