[0008] In some embodiments, the water receiving tray further includes a second sidewall connected to the bottom wall and located downstream of the air outlet side. The projection of the second sidewall on the plane of the air outlet side does not exceed the highest position of the projection of the second heat exchange tube on the plane of the air outlet side.

[0012] In some embodiments, the water receiving tray is configured to form a low water level and a high water level, the low water level intersecting the first sidewall and the bottom wall respectively, and the high water level intersecting the first sidewall and the second sidewall respectively.

[0013] In some embodiments, the distance between the highest and lowest points of the first sidewall is greater than H / 2, and / or the distance between the highest and lowest points of the second sidewall is greater than H / 2; wherein H is the distance between the lowest point of the bottom wall and the highest point of the second sidewall.

[0014] In some embodiments, the angle α formed between the first sidewall and the bottom wall is in the range of 130°-150°.

[0015] In some embodiments, the angle b formed between the second sidewall and the bottom wall ranges from 100° to 140°.

[0016] In some embodiments, a draining component is further included, which is disposed at the end of the water receiving tray and has a drain groove that communicates with the water receiving tray.

[0017] In some embodiments, the drainage component includes an end plate disposed at the end of the drainage channel and downstream of the second sidewall, wherein the projection of the end plate on the plane of the air outlet side does not exceed the highest position of the projection of the second heat exchange tube on the plane of the air outlet side.

[0018] In some embodiments, the drainage element includes a first baffle and a second baffle, with the drainage groove formed between the first baffle and the second baffle. The drainage groove extends obliquely downward toward the water receiving tray, with the upstream end of the first baffle located on the upstream side of the first sidewall and the upstream end of the second baffle located on the upstream side of the second sidewall.

[0024] In some embodiments, the projection of the first sidewall of the water receiving tray onto the plane of the air inlet side of the first heat exchanger does not exceed the highest position of the projection of the first heat exchange tube onto the plane of the air inlet side. Therefore, the first sidewall can minimize the obstruction of the airflow to the first heat exchange tube. Since the first heat exchange tube is at the lowest position, the corresponding first sidewall will not obstruct the airflow to other heat exchange tubes, enabling the first heat exchanger to achieve heat exchange smoothly and improving the heat exchange performance of the first heat exchanger. Furthermore, the first sidewall of the water receiving tray is located upstream of the air inlet side of the first heat exchanger and has a certain height, which can prevent the condensate in the water receiving tray from splashing to other positions and reduce the risk of water splashing.

[0050] The height direction involved in this embodiment is parallel to the vertical direction of the air conditioner in its normal placement state.

[0051] refer to Figures 1 to 3 In some embodiments, the heat exchange assembly includes a first heat exchanger 1 and a water receiving tray 3.

[0052] refer to Figures 1 to 3 The first heat exchanger 1 has an air inlet side 101 and an air outlet side 102, and the first heat exchanger 1 includes a plurality of heat exchange tubes 103.

[0053] refer to Figure 4 and Figure 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 region 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 of the air inlet side 101 does not exceed the highest position of the projection of the first heat exchange tube 11 on the plane of the air inlet side 101. The first heat exchange tube 11 is the lowest heat exchange tube on the air inlet side 101 among the multiple heat exchange tubes 103.

[0054] It should be noted that the heat exchange efficiency of a heat exchanger is mainly related to the heat exchange efficiency of the heat exchange tubes.

[0055] In the above embodiment, the bottom wall 33 of the water receiving tray 3 is located below the lowest region 104 of the first heat exchanger 1, and is used to receive the condensate generated by the first heat exchanger 1 to prevent the condensate generated by the first heat exchanger 1 from dripping onto other components and causing adverse effects on them; the first side wall 31 is located upstream of the air inlet side 101 and has a certain height, which can prevent the condensate in the water receiving tray 3 from splashing to other positions, reduce the risk of water splashing, and improve the heat exchange and dehumidification performance of the heat exchange component; and the projection of the first side wall 31 on the plane of the air inlet side 101 The first sidewall 31 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 sidewall 31 can minimize the obstruction of the airflow to the first heat exchange tube 11. Since the first heat exchange tube 11 is at the lowest position, the first sidewall 31 will not obstruct 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 obstructed, and heat exchange can be achieved smoothly. This maximizes the heat exchange efficiency of the first heat exchanger and improves the heat exchange efficiency and performance of the first heat exchanger 1.

[0056] In some embodiments, the side of the first sidewall 31 away from the bottom wall 33 does not exceed the first tangent A; the first tangent A is the upper tangent of the two tangents of the first heat exchange tube 11 that are perpendicular to the first sidewall 31.

[0057] In the above embodiment, among the tangents through the first heat exchange tube 11, there are two parallel tangents perpendicular to the first sidewall 31. The air passes through the first heat exchange tube 11 and is tangent to it. The upper tangent among the two tangents perpendicular to the first sidewall 31 is selected as the first tangent A. This ensures that the side of the first sidewall 31 away from the bottom wall 33 does not exceed the first tangent A. This allows the first sidewall 31 to avoid the first heat exchange tube 11 as much as possible along the wind direction while meeting the requirement of avoiding splashing of condensate in the water receiving pan 3. Among the multiple heat exchange tubes 103 of the first heat exchanger 1, the first heat exchange tube 11 is the lowest. Correspondingly, the first sidewall 31 will not block other heat exchange tubes, allowing more air to enter the first heat exchanger 1 to achieve heat exchange smoothly, thereby improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0058] In some embodiments, the water receiving tray 3 further includes a second sidewall 32, which is connected to the bottom wall 33 and located downstream of the air outlet side 102. The projection of the second sidewall 32 on the plane of the air outlet side 102 does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane of the air outlet side 102. The second heat exchange tube 12 is the heat exchange tube among the plurality of heat exchange tubes 103 that is not located on the air inlet side 101 and has the lowest position.

[0059] In the above embodiment, the second sidewall 32 is located downstream of the air outlet side 102 and has a certain height to prevent condensate in the water receiving pan 3 from splashing to other locations, reducing the risk of water splashing. Furthermore, the projection of the second sidewall 32 on the plane of the air outlet side 102 does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane of the air outlet side 102. The second sidewall 32 will not obstruct the second heat exchange tube 12. 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 sidewall 32 will not obstruct other heat exchange tubes, allowing the air that has completed heat exchange in the first heat exchanger 1 to flow smoothly out through the air outlet side 102, enabling the first heat exchanger to achieve heat exchange smoothly and improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0060] In some embodiments, the side of the second sidewall 32 away from the bottom wall 33 does not exceed the second tangent B; the second tangent B is the lower of the two tangents of the second heat exchange tube 12 that are perpendicular to the second sidewall 32.

[0061] In the above embodiment, among the tangents of the second heat exchange tube 12, there are two parallel tangents perpendicular to the second sidewall 32. The air passes through the second heat exchange tube 12 and is tangent to it. The lower tangent among the two tangents perpendicular to the second sidewall 32 is selected as the second tangent B, so that the side of the second sidewall 32 away from the bottom wall 33 does not exceed the second tangent B. This allows the second sidewall 32 to avoid the second heat exchange tube 12 as the air flows upward. 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. Accordingly, the second sidewall 32 will not block other heat exchange tubes. Therefore, the air that has completed heat exchange in the first heat exchanger 1 can flow out smoothly through the air outlet side 102, improving the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0062] In some embodiments, the bottom wall 33 is inclined.

[0063] In the above embodiment, the bottom wall 33 is located below the lowest region 104 of the first heat exchanger 1 and is used to receive the condensate generated by the first heat exchanger 1. The bottom wall 33 is inclined so that the condensate can be diverted to the lower part of the bottom wall 33, which can better contain the condensate and prevent the condensate from splashing to other places, thus reducing the risk of water blowing.

[0064] In some embodiments, the first heat exchanger 1 is inclined, the highest point of the air inlet side 101 of the first heat exchanger 1 is located 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.

[0065] In some embodiments, the lower side 333 of the bottom wall 33 is connected to the first side wall 31, and the higher side 334 of the bottom wall 33 is connected to the second side wall 32.

[0066] In the above embodiment, since the bottom wall 33 is inclined, the lower side 333 of the bottom wall 33 is connected to the first side wall 31, and the higher side 334 of the bottom wall 33 is connected to the second side wall 32. Therefore, the water receiving tray 3 is inclined. Due to gravity, condensate flows from high to low, so the condensate in the water receiving tray 3 will flow to the lower side 333 of the bottom wall 33, so that the water receiving tray 3 can better accommodate the condensate and prevent the condensate from splashing to other places, reducing the risk of water blowing. Moreover, the windward side of the water receiving tray 3 is low, and the air outlet side is high. The inclination direction of the water receiving tray 3 is roughly the same as the inclination direction of the first heat exchanger 1, and the inner side of the water receiving tray 3, that is, the side closer to the fan, is the lower side of the water receiving tray 3, which is conducive to smoothly guiding the condensate of the first heat exchanger 1 to the water receiving tray 3.

[0067] refer to Figure 6 and Figure 7 In some embodiments, the water receiving tray 3 is configured to form a low water level 331 and a high water level 332, with the low water level 331 intersecting the first side wall 31 and the bottom wall 33 respectively, and the high water level 332 intersecting the first side wall 31 and the second side wall 32 respectively.

[0068] In the above embodiment, when the first heat exchanger 1 generates condensate during normal operation, the condensate drips into the water receiving pan 3 due to its own gravity. The water receiving pan 3 has a water storage function, so the condensate can be stored and retained within it. Since the water receiving pan 3 is inclined, and its windward side is its lower side, when the amount of water in the water receiving pan 3 is low, the low water level 331 formed by the condensate intersects with the first sidewall 31 and the bottom wall 33 respectively (see reference). Figure 6 When the water level in the drip tray 3 is high, the high water level 332 formed by the condensate intersects with the first side wall 31 and the second side wall 32 respectively (see reference). Figure 7 The above-mentioned settings of the water receiving tray 3 can be applied to both large and small water volumes, making it highly adaptable.

[0069] In some embodiments, the distance between the highest and lowest points of the first sidewall 31 is greater than the distance between the highest and lowest points of the second sidewall 32.

[0070] In the above embodiment, since the water receiving tray 3 is inclined 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, the distance between the highest point and the lowest point of the first side wall 31 is greater than the distance between the highest point and the lowest point of the second side wall 32, the first side wall 31 has a relatively higher height dimension relative to the second side wall 32, which enables the first side wall 31 to more effectively prevent condensate from overflowing and ensure the water storage function of the water receiving tray 3.

[0071] refer to Figure 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 condensate in the water receiving tray 3 from overflowing and ensure the water storage function of the water receiving tray 3.

[0072] refer to Figure 5 In some embodiments, the distance between the highest and lowest points of the first sidewall 31 is greater than H / 2.

[0073] In some embodiments, the distance between the highest and lowest points of the second sidewall 32 is greater than H / 2.

[0074] Where 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.

[0075] In the above embodiment, since the condensate entering the water receiving pan will cause splashing, the height of the first side wall 31 and the second side wall 32 of the water receiving pan 3 is greater than H / 2, which can control the splashing phenomenon inside the water receiving pan 3 and prevent the condensate from splashing onto other components and sheet metal parts, thus preventing the risk of condensation; it can also prevent the condensate from splashing into the dehumidifying evaporator and affecting the dehumidifying efficiency of the dehumidifying evaporator.

[0076] refer to Figure 4 In some embodiments, the angle α formed between the first sidewall 31 and the bottom wall 33 is in the range of 130°-150°.

[0077] In the above embodiment, the angle α formed between the first sidewall 31 and the bottom wall 33 is limited to 130°-150°, which allows the first sidewall 31 to have an appropriate gap with the air inlet side 101 of the first heat exchanger 1. This avoids the phenomenon that the gap is too small due to production and assembly errors, which would prevent the condensate from flowing smoothly into the water receiving pan 3. In addition, the first sidewall 31 is inclined, which has a guiding effect, allowing the condensate to enter the water receiving pan 3 smoothly and preventing the condensate in the water receiving pan 3 from splashing.

[0078] Optionally, the angle α formed between the first sidewall 31 and the bottom wall 33 is 132°.

[0079] In some embodiments, the angle b formed between the second sidewall 32 and the bottom wall 33 ranges from 100° to 140°.

[0080] Optionally, the angle b formed between the second sidewall 32 and the bottom wall 33 is 138°.

[0081] In the above embodiment, the angle b formed between the second sidewall 32 and the bottom wall 33 is limited to 100°-140°, which allows the second sidewall 32 to have an appropriate gap with the air outlet side 102 of the first heat exchanger 1. This avoids the phenomenon that the gap is too small due to production and assembly errors, which would prevent the condensate from flowing smoothly into the water receiving pan 3. In addition, the second sidewall 32 is inclined, which has a guiding effect, allowing the condensate to enter the water receiving pan 3 smoothly and preventing the condensate in the water receiving pan 3 from splashing.

[0082] refer to Figure 1 , Figure 2 , Figure 9 and Figure 10 In some embodiments, the heat exchange assembly further includes a drain component 4, which is located at the end of the water receiving pan 3. The drain component 4 is provided with a drain groove 41, which is connected to the water receiving pan 3.

[0083] In the above embodiment, the water receiving tray 3 can receive condensate, and the drain groove 41 on the drain component 4 is used to drain the condensate in the water receiving tray 3. In this way, even if the unit produces a lot of condensate, there will be no problem of condensate overflow due to lack of storage space, which will affect the performance of the unit.

[0084] In some embodiments, a drain component 4 is provided at each end of the water receiving pan 3. The two drain components 4 discharge the condensate in the water receiving pan 3 from both ends of the water receiving pan 3. Therefore, even if the unit produces a lot of condensate, there will be no problem of condensate overflow affecting the unit's performance due to lack of storage space.

[0085] In some embodiments, the drainage member 4 includes an end plate 42, which is disposed at the end of the drainage groove 41 and located downstream of the second side wall 32. The projection of the end plate 42 on the plane of the air outlet side 102 does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane of the air outlet side 102.

[0086] In the above embodiment, the end plate 42 is disposed at the end of the drain trough 41, which can prevent condensate from splashing from the end of the drain trough 41. The projection of the end plate 42 on the plane of the air outlet side 102 does not exceed the highest position of the projection of the second heat exchange tube 12 on the plane of the air outlet side 102. The end plate 42 will not obstruct the second heat exchange tube 12. 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 end plate 42 will not obstruct other heat exchange tubes. This allows the air that has completed heat exchange in the first heat exchanger 1 to flow smoothly out through the air outlet side 102, so that the first heat exchanger can smoothly achieve heat exchange and improve the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0087] In some embodiments, the drainage member 4 includes a first baffle 43 and a second baffle 44, with a drainage groove 41 formed between the first baffle 43 and the second baffle 44. The drainage groove 41 extends obliquely downward toward the water receiving tray 3. The upstream end of the first baffle 43 is located on the upstream side of the first sidewall 31, and the upstream end of the second baffle 44 is located on the upstream side of the second sidewall 32.

[0088] In the above embodiment, the upstream end of the first baffle 43 is located on the upstream side of the first sidewall 31, and the upstream end of the second baffle 44 is located on the upstream side of the second sidewall 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 drain trough 41, and the drain trough 41 extends obliquely downwards from the water receiving tray 3. The first baffle 43 and the second baffle 44 extend obliquely downwards from the water receiving tray 3, which can smoothly draw out the condensate in the water receiving tray 3.

[0089] 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 neither the first baffle 43 nor the second baffle 44 is 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.

[0090] In the above embodiment, the bottom of the drainage trough 41 is lower than the bottom wall 33, which can guide the water in the water receiving tray 3 to the drainage trough 41 in a timely manner. The first baffle 43 and the second baffle 44 have a certain height, both higher than the bottom wall 33, which can prevent the condensate in the drainage trough 41 from overflowing and ensure the drainage function of the drainage trough 41. 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 obstruct the second heat exchange tube 12. 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 first baffle 43 and the second baffle 44 will not obstruct other heat exchange tubes, so that the air that has completed heat exchange in the first heat exchanger 1 can flow out smoothly through the air outlet side 102, so that the first heat exchanger 1 can smoothly achieve heat exchange and improve the heat exchange efficiency and heat exchange performance of the first heat exchanger 1.

[0091] In some embodiments, both the first baffle 43 and the second baffle 44 are higher than the bottom wall 33 and neither is higher than the second side wall 32.

[0092] In the above embodiment, the height of the first baffle 43 and the second baffle 44 allows condensate to flow smoothly from the water receiving tray 3 into the drain trough 41 without splashing or overflowing.

[0093] In some embodiments, the two ends of the water receiving tray 3 correspond to the two ends of the first heat exchanger 1 respectively.

[0094] In the above embodiment, the length of the water receiving tray 3 is slightly longer than the length of the first heat exchanger 1, so that all the condensate generated by the first heat exchanger 1 can flow into the water receiving tray 3, preventing the condensate from flowing to other places.

[0096] In some related technologies, both the first heat exchanger 1 and the second heat exchanger 2 are evaporators. When the first heat exchanger 1 is used for dehumidification, the condensate produced by the first heat exchanger 1 drips vertically from its fins onto the fins of the second heat exchanger 2, and then drips into a foam drip tray. This dripping of condensate from the first heat exchanger 1 onto the second heat exchanger 2 affects its heat exchange efficiency.

[0097] Based on this, in the above embodiments provided in this disclosure, a water receiving tray 3 is placed between the first heat exchanger 1 and the second heat exchanger 2. The condensate generated by the first heat exchanger 1 can enter the water receiving tray 3 under the action of gravity, avoiding the condensate from remaining in the first heat exchanger 1 and affecting the dehumidification efficiency of the first heat exchanger 1.

[0100] In some embodiments, the heat exchange assembly further includes a bottom water receiving tray, which is located below the second heat exchanger 2. Each end of the water receiving tray 3 is equipped with a drain trough 41, which is used to drain the condensate stored in the water receiving tray 3 into the bottom water receiving tray.

[0101] Optionally, the bottom drip tray includes a foam drip tray.

[0102] In some embodiments, the heat exchange assembly further includes a side plate 6, which is disposed at the end of the first heat exchanger 1 and is used to fix the first heat exchanger 1. The end of the water receiving tray 3 is fixed to the side plate 6. The drain component 4 is fixed to the side plate 6.

[0103] Optionally, both the water tray 3 and the drain component 4 are fixed to the side plate 6 with screws, making assembly simple.

[0104] In some embodiments, the water receiving tray 3 is fixed to the side plate 6 of the first heat exchanger 1 by two screws.

[0106] The connecting part 34 is a protruding extension structure on the first side wall 31, which is used to connect with the side plate 6 by setting screws. The connecting part 34 only needs to be able to set screws and does not need to be too large. Therefore, it will not have a significant obstruction effect on the first heat exchange tube 11.

[0107] In some embodiments, a drain component 4 is provided at each end of the water receiving tray 3, and the two drain components 4 are fixed to the side plate 6 of the second heat exchanger 2 by screws; the fixing method is reliable and the form is simple and convenient for production operation.

[0108] In some embodiments, the heat exchange assembly further includes a fan 5, which provides air that enters through the air inlet side 101 of the first heat exchanger 1 and flows out through the air outlet side 102 of the first heat exchanger 1.

[0109] Some embodiments of this disclosure also provide an air conditioner that includes the heat exchange component of any of the above embodiments.

[0110] The air conditioner provided in this disclosure includes the heat exchange component in any of the above embodiments, and accordingly has the beneficial effects of the heat exchange component.

[0111] In some embodiments, the heat exchange assembly includes a first heat exchanger 1, a second heat exchanger 2, and a water receiving tray 3. The second heat exchanger 2 is disposed below the first heat exchanger 1, and the water receiving tray 3 is disposed between the first heat exchanger 1 and the second heat exchanger 2.

[0112] In some embodiments, the heat exchange assembly has a symmetrical structure. The water receiving tray 3 is placed between the first heat exchanger 1 and the second heat exchanger 2.

[0113] In some embodiments, the air conditioner includes a temperature-controlled and dehumidifying duct unit.

[0114] In some embodiments, the heat exchange component is the heat exchange component of an indoor air conditioning unit.

[0115] In a specific temperature control and dehumidification mode, the upper first heat exchanger 1 is a dehumidification evaporator, and the lower second heat exchanger 2 is a heat exchange evaporator.

[0116] When the unit is operating in cooling mode, both the upper and lower heat exchangers are cooling heat exchangers. When the unit is operating in heating mode, both the upper and lower heat exchangers are heating heat exchangers.
