[0037] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0038] In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure.

[0039] Some embodiments of the present disclosure provide a heat exchange assembly and an air conditioner, which are used to alleviate the problem of affected heat exchange performance of a heat exchanger.

[0040] The height direction involved in the embodiment of the present disclosure is parallel to the up-down direction of the air conditioner in a normal placement state.

[0041] 1 to 3 , in some embodiments, the heat exchange assembly includes a first heat exchanger 1 and a water receiving tray 3 .

[0042] 1 to 3 , the first heat exchanger 1 has an air inlet side 101 and an air outlet side 102 , and includes a plurality of heat exchange tubes 103 .

[0043] 4 and 5 , the water receiving tray 3 includes a bottom wall 33 and a first side wall 31. The bottom wall 33 is located below the lowest area 104 of the first heat exchanger 1. The first side wall 31 is connected to the bottom wall 33 and is located upstream of the air inlet side 101. The projection of the first side wall 31 on the plane where the air inlet side 101 is located does not exceed the highest position of the projection of the first heat exchange tube 11 on the plane where the air inlet side 101 is located. The first heat exchange tube 11 is the heat exchange tube located on the air inlet side 101 and is the lowest heat exchange tube among the multiple heat exchange tubes 103.

[0044] It should be noted that the heat transfer efficiency of the heat exchanger is mainly related to the heat transfer efficiency of the heat exchange tubes.

[0045] In the above embodiment, the bottom wall 33 of the water receiving tray 3 is located below the lowest area 104 of the first heat exchanger 1, and is used to receive the condensed water generated by the first heat exchanger 1 to prevent the condensed water generated by the first heat exchanger 1 from dripping onto other components and causing adverse effects on other components; the first side wall 31 is located upstream of the air inlet side 101 and has a certain height, which can prevent the condensed water in the water receiving tray 3 from splashing to other locations, reducing the risk of water blowing and improving the heat exchange and dehumidification performance of the heat exchange component; and the projection of the first side wall 31 on the plane where the air inlet side 101 is located The first side wall 31 does not block the airflow to the first heat exchange tube 11 as much as possible, and the first heat exchange tube 11 is at the lowest position. Accordingly, the first side wall 31 will not block the airflow to other heat exchange tubes. When the air blown out by the fan passes through the first heat exchanger 1, the heat exchange tubes in the first heat exchanger 1 are not blocked, and heat exchange can be smoothly achieved, so that the first heat exchanger can achieve the most efficient heat exchange work as much as possible, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0046] In some embodiments, the side of the first side wall 31 away from the bottom wall 33 does not exceed the first tangent line A; the first tangent line A is the upper tangent line of the first heat exchange tube 11 between the two tangent lines perpendicular to the first side wall 31 .

[0047] In the above embodiment, among the tangents passing through the first heat exchange tube 11, there are two parallel tangents perpendicular to the first side wall 31. The wind passes through the first heat exchange tube 11 and is tangent to the first heat exchange tube 11. The tangent located above the two tangents perpendicular to the first side wall 31 is selected as the first tangent A, so that the side of the first side wall 31 away from the bottom wall 33 does not exceed the first tangent A. This allows the first side wall 31 to avoid the first heat exchange tube 11 as much as possible in the wind direction while meeting the requirement of avoiding splashing of condensed water in the water receiving tray 3. The first heat exchange tube 11 is located at the lowest position among the multiple heat exchange tubes 103 of the first heat exchanger 1, and the corresponding first side wall 31 will not block other heat exchange tubes, so that more wind can enter the first heat exchanger 1 to smoothly realize heat exchange, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0048] In some embodiments, the water receiving tray 3 also includes a second side wall 32, which is connected to the bottom wall 33 and is located downstream of the air outlet side 102. The projection of the second side wall 32 on the plane where the air outlet side 102 is located does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane where the air outlet side 102 is located; the second heat exchange tube 12 is the heat exchange tube that is not located on the air inlet side 101 and is located at the lowest position among the multiple heat exchange tubes 103.

[0049] In the above embodiment, the second side wall 32 is located downstream of the air outlet side 102 and has a certain height, which is used to prevent the condensed water in the water receiving tray 3 from splashing to other locations, reducing the risk of water blowing, and the projection of the second side wall 32 on the plane where the air outlet side 102 is located does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane where the air outlet side 102 is located. The second side wall 32 will not block the second heat exchange tube 12, and the second heat exchange tube 12 is the lowest heat exchange tube among the multiple heat exchange tubes 103 that is not located on the air inlet side 101. Therefore, the second side wall 32 will not block other heat exchange tubes, and can enable the wind that completes heat exchange in the first heat exchanger 1 to flow out smoothly through the air outlet side 102, so that the first heat exchanger can smoothly realize heat exchange, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0050] In some embodiments, the side of the second side wall 32 away from the bottom wall 33 does not exceed the second tangent line B; the second tangent line B is the lower tangent line of the second heat exchange tube 12 between the two tangent lines perpendicular to the second side wall 32 .

[0051] In the above embodiment, among the tangents passing through the second heat exchange tube 12, there will be two parallel tangents perpendicular to the second side wall 32. The wind passes through the second heat exchange tube 12 and is tangent to the second heat exchange tube 12. The tangent located below the two tangents perpendicular to the second side wall 32 is selected as the second tangent B, so that the side of the second side wall 32 away from the bottom wall 33 does not exceed the second tangent B, which can enable the second side wall 32 to avoid the second heat exchange tube 12 in the wind direction. The second heat exchange tube 12 is the heat exchange tube that is not located on the air inlet side 101 and is at the lowest position among the multiple heat exchange tubes 103. The corresponding second side wall 32 will not block other heat exchange tubes. Therefore, the wind that completes heat exchange in the first heat exchanger 1 can smoothly flow out through the air outlet side 102, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0052] In some embodiments, the bottom wall 33 is inclined.

[0053] In the above embodiment, the bottom wall 33 is located below the lowest area 104 of the first heat exchanger 1 and is used to receive the condensed water generated by the first heat exchanger 1. The bottom wall 33 is inclined to drain the condensed water so that the condensed water flows to the lower position of the bottom wall 33, thereby better accommodating the condensed water, preventing the condensed water from splashing to other locations, and reducing the risk of water blowing.

[0054] In some embodiments, the first heat exchanger 1 is tilted, the highest point of the air inlet side 101 of the first heat exchanger 1 is upstream of the lowest point, and the angle between the air inlet side 101 of the first heat exchanger 1 and the horizontal plane is greater than zero and less than 90 degrees.

[0055] In some embodiments, the lower side 333 of the bottom wall 33 is connected to the first side wall 31 , and the upper side 334 of the bottom wall 33 is connected to the second side wall 32 .

[0056] In the above embodiment, because the bottom wall 33 is tilted, the low side 333 of the bottom wall 33 is connected to the first side wall 31, and the high side 334 of the bottom wall 33 is connected to the second side wall 32. Therefore, the water receiving pan 3 is tilted. Due to the effect of gravity, condensed water flows from a high point to a low point. Therefore, the condensed water in the water receiving pan 3 will flow to the low side 333 of the bottom wall 33, so that the water receiving pan 3 can better contain the condensed water, prevent the condensed water from splashing to other locations, and reduce the risk of water splashing. In addition, the windward side of the water receiving pan 3 is positioned low, and the windward side is positioned high. The tilt direction of the water receiving pan 3 is generally consistent with the tilt direction of the first heat exchanger 1. The inner side of the water receiving pan 3, that is, the side closest to the fan, is the low side of the water receiving pan 3, which facilitates the smooth guidance of condensed water from the first heat exchanger 1 to the water receiving pan 3.

[0057] 6 and 7 , in some embodiments, the water tray 3 is configured to form a low water level 331 and a high water level 332 therein, wherein the low water level 331 intersects the first side wall 31 and the bottom wall 33 respectively, and the high water level 332 intersects the first side wall 31 and the second side wall 32 respectively.

[0058] In the above embodiment, when the first heat exchanger 1 operates normally and produces condensed water, the condensed water drips into the water receiving pan 3 due to its own gravity, and the water receiving pan 3 has a water storage function, so the condensed water can be stored and stayed in the water receiving pan 3. Since the water receiving pan 3 is arranged at an angle, and the windward side of the water receiving pan 3 is the low side of the water receiving pan 3, when the amount of water in the water receiving pan 3 is small, the low water level 331 formed by the condensed water intersects with the first side wall 31 and the bottom wall 33 respectively (refer to Figure 6). When the amount of water in the water receiving pan 3 is large, the high water level 332 formed by the condensed water intersects with the first side wall 31 and the second side wall 32 respectively (refer to Figure 7). The above-mentioned setting of the water receiving pan 3 can be applied to situations with large and small amounts of water, and has strong applicability.

[0059] In some embodiments, the distance between the highest point and the lowest point of the first sidewall 31 is greater than the distance between the highest point and the lowest point of the second sidewall 32 .

[0060] In the above embodiment, since the water receiving tray 3 is arranged at an angle, and the windward side of the water receiving tray 3 is the low side of the water receiving tray 3, the first side wall 31 is connected to the low side 333 of the bottom wall 33, and the distance between the highest point to the lowest point of the first side wall 31 is greater than the distance between the highest point to the lowest point of the second side wall 32. The first side wall 31 has a relatively high height dimension relative to the second side wall 32, which can enable the first side wall 31 to more effectively prevent condensation water from overflowing, thereby ensuring the water storage function of the water receiving tray 3.

[0061] 8 , the water receiving tray 3 includes a bottom wall 33, and a first side wall 31 and a second side wall 32 connected to the bottom wall 33. The first side wall 31 and the second side wall 32 have a certain height, which can effectively prevent the condensed water in the water receiving tray 3 from overflowing, thereby ensuring the water storage function of the water receiving tray 3.

[0062] 5 , in some embodiments, the distance between the highest point and the lowest point of the first sidewall 31 is greater than 1 / 2H.

[0063] In some embodiments, the distance between the highest point and the lowest point of the second sidewall 32 is greater than 1 / 2H.

[0064] Here, H is the distance between the lowest point C of the bottom wall 33 and the highest point D of the second side wall 32 .

[0065] In the above embodiment, since condensed water will splash when it enters the water receiving tray, the height of the first side wall 31 and the second side wall 32 of the water receiving tray 3 is greater than 1 / 2H, which can control the splashing phenomenon inside the water receiving tray 3 and prevent the condensed water from splashing onto other components and sheet metal parts to cause condensation risk; it can also prevent the condensed water from splashing into the dehumidification evaporator and affecting the dehumidification efficiency of the dehumidification evaporator.

[0066] 4 , in some embodiments, the angle a formed between the first side wall 31 and the bottom wall 33 is in the range of 130°-150°.

[0067] In the above embodiment, the angle range of the angle a formed between the first side wall 31 and the bottom wall 33 is limited to 130°-150°, which can ensure that the first side wall 31 and the air inlet side 101 of the first heat exchanger 1 have an appropriate gap, thereby avoiding the phenomenon that the gap is too small due to production and assembly errors, thereby preventing the condensed water from flowing smoothly into the water receiving tray 3. The first side wall 31 is inclined and has a drainage effect, which can enable the condensed water to enter the water receiving tray 3 smoothly and prevent the condensed water in the water receiving tray 3 from splashing.

[0068] Optionally, the angle a formed between the first side wall 31 and the bottom wall 33 is 132°.

[0069] In some embodiments, the angle b formed between the second side wall 32 and the bottom wall 33 is in the range of 100°-140°.

[0070] Optionally, the angle b formed between the second side wall 32 and the bottom wall 33 is 138°.

[0071] In the above embodiment, the angle range of the angle b formed between the second side wall 32 and the bottom wall 33 is limited to 100°-140°, which can ensure that the second side wall 32 and the air outlet side 102 of the first heat exchanger 1 have an appropriate gap, thereby avoiding the phenomenon that the gap is too small due to production and assembly errors, thereby preventing the condensed water from flowing smoothly into the water receiving tray 3. The second side wall 32 is arranged at an angle and has a drainage effect, which can enable the condensed water to enter the water receiving tray 3 smoothly and prevent the condensed water in the water receiving tray 3 from splashing.

[0072] 1 , 2 , 9 and 10 , in some embodiments, the heat exchange assembly further includes a drain member 4 , which is disposed at the end of the water receiving tray 3 . The drain member 4 is provided with a drain groove 41 , which is connected to the water receiving tray 3 .

[0073] In the above embodiment, the water receiving tray 3 can receive condensed water, and the drainage groove 41 on the drainage member 4 is used to drain the condensed water in the water receiving tray 3. In this way, even if the unit produces more condensed water, there will be no problem of condensed water overflowing due to lack of storage space, affecting the performance of the unit.

[0074] In some embodiments, a drainage member 4 is provided at each end of the water receiving tray 3. The two drainage members 4 discharge the condensed water in the water receiving tray 3 from both ends of the water receiving tray 3 respectively. Therefore, even if the unit generates more condensed water, there will be no problem of condensed water overflowing due to lack of storage space, affecting the performance of the unit.

[0075] In some embodiments, the drainage member 4 includes an end plate 42, which is arranged at the end of the drainage groove 41 and is located downstream of the second side wall 32. The projection of the end plate 42 on the plane where the air outlet side 102 is located does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane where the air outlet side 102 is located.

[0076] In the above embodiment, the end plate 42 is arranged at the end of the drainage groove 41, which can prevent condensed water from splashing from the end of the drainage groove 41, and the projection of the end plate 42 on the plane where the air outlet side 102 is located does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane where the air outlet side 102 is located. The end plate 42 will not block the second heat exchange tube 12, and the second heat exchange tube 12 is the heat exchange tube that is not located on the air inlet side 101 and is at the lowest position among the multiple heat exchange tubes 103. Therefore, the end plate 42 will not block other heat exchange tubes, and can enable the wind that completes heat exchange in the first heat exchanger 1 to flow out smoothly through the air outlet side 102, so that the first heat exchanger can smoothly realize heat exchange, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0077] In some embodiments, the drainage member 4 includes a first baffle 43 and a second baffle 44, and a drainage groove 41 is formed between the first baffle 43 and the second baffle 44. The drainage groove 41 extends obliquely downward of the water receiving tray 3. The upstream end of the first baffle 43 is located on the upstream side of the first side wall 31, and the upstream end of the second baffle 44 is located on the upstream side of the second side wall 32.

[0078] In the above embodiment, the upstream end of the first baffle 43 is located on the upstream side of the first side wall 31, and the upstream end of the second baffle 44 is located on the upstream side of the second side wall 32. A gap 45 is formed between the upstream ends of the first baffle 43 and the second baffle 44. The gap 45 connects the water receiving tray 3 and the drainage groove 41, and the drainage groove 41 extends obliquely downward of the water receiving tray 3. The first baffle 43 and the second baffle 44 extend obliquely downward of the water receiving tray 3, which can smoothly draw out the condensed water in the water receiving tray 3.

[0079] In some embodiments, the bottom of the drainage trough 41 is lower than the bottom wall 33, the first baffle 43 and the second baffle 44 are both higher than the bottom wall 33, and the first baffle 43 and the second baffle 44 are both not higher than the highest position of the projection of the second heat exchange tube 12 on the plane where the air outlet side 102 is located.

[0080] In the above embodiment, the bottom of the drainage trough 41 is lower than the bottom wall 33, which can promptly guide the water in the water receiving tray 3 to the drainage trough 41, and the first baffle 43 and the second baffle 44 have a certain height, both higher than the bottom wall 33, which can prevent the condensed water in the drainage trough 41 from overflowing, thereby ensuring the drainage function of the drainage trough 1, and the first baffle 43 and the second baffle 44 are not higher than the highest position of the projection of the second heat exchange tube 12 on the plane where the air inlet side 101 is located, and will not block the second heat exchange tube 12. The second heat exchange tube 12 is the heat exchange tube that is not located on the air inlet side 101 and is at the lowest position among the multiple heat exchange tubes 103. Therefore, the first baffle 43 and the second baffle 44 will not block other heat exchange tubes, and can enable the wind that completes heat exchange in the first heat exchanger 1 to flow out smoothly through the air outlet side 102, so that the first heat exchanger 1 can smoothly realize heat exchange, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0081] In some embodiments, the first baffle 43 and the second baffle 44 are both higher than the bottom wall 33 , and are not higher than the second side wall 32 .

[0082] In the above embodiment, the heights of the first baffle 43 and the second baffle 44 enable the condensed water to flow smoothly from the water receiving tray 3 into the drain groove 41 without splashing or overflowing.

[0083] In some embodiments, both ends of the water receiving tray 3 correspond to and exceed both ends of the first heat exchanger 1 .

[0084] In the above embodiment, the length of the water receiving pan 3 is slightly longer than that of the first heat exchanger 1 , so that all the condensed water generated by the first heat exchanger 1 can flow into the water receiving pan 3 and prevent the condensed water from flowing to other places.

[0085] In some embodiments, the heat exchange assembly further includes a second heat exchanger 2 , which is disposed below the first heat exchanger 1 , and the bottom wall 33 of the water receiving tray 3 is higher than the highest area 201 of the second heat exchanger 2 .

[0086] In some related technologies, when both first heat exchanger 1 and second heat exchanger 2 are evaporators and first heat exchanger 1 is used for dehumidification, condensed water generated by first heat exchanger 1 will drip vertically along the fins of first heat exchanger 1 onto the fins of second heat exchanger 2. The condensed water will then drip into the foam water receiving pan along the fins of second heat exchanger 2. This condensed water generated by first heat exchanger 1 dripping onto second heat exchanger 2 will affect the heat exchange performance of second heat exchanger 2.

[0087] Based on this, in the above embodiment provided in the present disclosure, a water receiving tray 3 is placed between the first heat exchanger 1 and the second heat exchanger 2.
