[0055] In some embodiments, the drainage groove 54 can be formed by the baffle 545 provided on the bracket 5, and the baffle 545 is provided to form the drainage groove 54 and also serves as a rib plate of the bracket 5 to improve the strength of the bracket 5.

[0056] In some embodiments, the heat exchange assembly further comprises a shell, and the first heat exchanger 1 and the first water pan 3 are both fixed in the shell through the bracket 5. Therefore, the bracket 5 has the functions of fixing and supporting the first heat exchanger 1 and the first water pan 3, and also has the function of draining water.

[0057] Reference Figure 2 In some embodiments, the first heat exchanger 1 comprises a first side plate 11, the first side plate 11 is arranged at the end of the first heat exchanger 1, and the first side plate 11 is connected to the bracket 5.

[0060] In the above-mentioned embodiments, the bracket 5 is used to support the first heat exchanger 1 and the second heat exchanger 2 at the same time, and the bracket 5 is also provided with the drainage groove 54, which can timely drain the condensed water in the first water pan 3, thereby relieving the influence of the condensed water on other components, for example, preventing the condensed water from being retained in the first heat exchanger 1 to affect the dehumidification rate of the first heat exchanger 1, and preventing the condensed water from falling into the second heat exchanger 2 to delay the heat exchange effect of the second heat exchanger 2.

[0061] Reference Figure 2In some embodiments, the second heat exchanger 2 comprises a second side plate 21 arranged at the end of the second heat exchanger 2, and the second side plate 21 is connected to the support 5.

[0062] In some embodiments, the second heat exchanger 2 comprises a plurality of heat exchange pipes.

[0063] In some embodiments, the second heat exchanger 2 is arranged below the first water pan 3, and the first water pan 3 is arranged between the first heat exchanger 1 and the second heat exchanger 2. The drain groove 54 extends from the first water pan 3 to below the second heat exchanger 2.

[0064] In the above embodiments, the first heat exchanger 1 is located at the top, the second heat exchanger 2 is located at the bottom, and the first water pan 3 is placed between the first heat exchanger 1 and the second heat exchanger 2. The first water pan 3 is used to collect and store the condensed water generated by the first heat exchanger 1, and the condensed water in the first water pan 3 is smoothly drained along the drain groove 54 on the support 5; it can prevent the condensed water generated by the first heat exchanger 1 from falling onto the second heat exchanger 2, affecting the heat exchange and dehumidification effect of the second heat exchanger 2.

[0065] In some embodiments, one of the same ends of the first heat exchanger 1 and the second heat exchanger 2 is provided with a support, and the other same end is provided with another support. The first heat exchanger 1 and the second heat exchanger 2 are arranged in an upper and lower manner, and the two ends of the first heat exchanger 1 and the second heat exchanger 2 are respectively provided with a support 5. The first heat exchanger 1 and the second heat exchanger 2 are supported by the supports 5 arranged at the two ends, and are fixed in the shell by the supports 5.

[0066] In some embodiments, the first heat exchanger 1 and the second heat exchanger 2 are arranged symmetrically.

[0067] In some embodiments, along the direction of the wind flowing to the first heat exchanger 1, the drain groove 54 extends first in the downstream direction from the first water pan 3, and then extends in the upstream direction.

[0068] In the above embodiments, the drain groove 54 extends first in the downstream direction from the first water pan 3, which can smoothly guide the condensed water out along the flow direction of the wind. However, if the condensed water continues to extend in the downstream direction, it will be too close to the air outlet part of the heat exchange assembly, causing condensation problems in the air outlet part of the heat exchange assembly. Therefore, the drain groove 54 is arranged in a turning structure, which extends first in the downstream direction from the first water pan 3, and then extends in the upstream direction, away from the air outlet part of the heat exchanger assembly, to avoid being too close to the air outlet part of the heat exchange assembly and causing condensation problems.

[0069] Reference Figure 2In some embodiments, the heat exchange assembly further comprises a second heat exchanger 2 arranged below the first heat exchanger 1, and the end of the second heat exchanger 2 is connected to the support 5, and the starting point C of the water drainage groove 54 extending in the upstream direction is lower than the first heat exchange tube 22 closest to the water drainage groove 54 among the plurality of heat exchange tubes at the lowermost position of the second heat exchanger 2.

The support 5 is also provided with a drainage groove 54 for discharging the condensed water in the first water pan 3, so that it is no longer necessary to additionally arrange a drainage member to guide the drainage, reducing the number of parts, reducing the cost, and improving the production efficiency.

[0084] In the above embodiment, the support 5 arranged at the end of the first heat exchanger 1 and the second heat exchanger 2 is a whole support, which fixes the two heat exchangers and the first water pan 3 at the same time. The support 5 is also provided with a drainage groove 54 for discharging the condensed water in the first water pan 3, so that it is no longer necessary to additionally arrange a drainage member to guide the drainage, reducing the number of parts, reducing the cost, and improving the production efficiency.

[0085] In some embodiments, the third support 53 and the second support 52 are provided with a drain groove 54.

[0086] In the above embodiments, the third support 53 and the second support 52 are provided with the drain groove 54, which can guide the condensed water downward from top to bottom, facilitating the discharge of the condensed water in the first water pan 3.

[0087] In some embodiments, the first heat exchanger 1 and the second heat exchanger 2 are arranged obliquely, the first support 51 is provided with a first inclined edge 511 connected with the first heat exchanger 1 on one side adjacent to the second support 52, and the second support 52 is provided with a second inclined edge 512 connected with the second heat exchanger 2 on one side adjacent to the first heat exchanger 1.

[0089] In some embodiments, the bracket 5 has a drain groove 54 in the middle and lower part.

[0090] Reference Figure 5 and Figure 7 In some embodiments, the bracket 5 includes a support plate 56, the bottom 544 of the drain groove 54 is lower than the plate surface 561 of the support plate 56, and the support plate 56 is provided with two baffles 545, and the drain groove 54 is formed between the two baffles 545.

[0091] In the above embodiments, the bottom 544 of the drain groove 54 is lower than the plate surface 561 of the support plate 56, which facilitates the introduction of the condensed water in the first water pan 3 to the drain groove 54, and the baffles 545 arranged on both sides of the drain groove 54 are used to guide the condensed water and prevent the condensed water from overflowing or splashing out of the drain groove 54.

[0092] In some embodiments, the distance between the bottom 544 of the drain groove 54 and the plate surface 561 of the support plate 56 is greater than or equal to 0.3 mm and less than or equal to 0.45 mm.

[0093] The height difference between the bottom 544 of the drain groove 54 and the plate surface 561 of the support plate 56 can enable the condensed water to flow normally into the drain groove 54 when the height of the baffle 545 is low.

[0094] Reference Figure 4 and Figure 5 In some embodiments, the height of the baffle 545 is higher than the plate surface 561 of the bracket 5 and lower than the maximum thickness D of the bracket 5.

[0095] In the above embodiments, the height of the baffle 545 is higher than the plate surface 561 of the bracket 5, which can form a drainage groove 54, so that the condensed water can flow smoothly into the drainage groove 54, and can also prevent the condensed water from splashing onto other components and sheet metal parts, thereby alleviating the problem of condensation; and the condensed water will not splash onto the second heat exchanger 2 (including the heat exchange pipes), thereby affecting the heat exchange effect of the second heat exchanger 2. The height of the baffle 545 is lower than the maximum thickness D of the bracket 5, which can prevent the baffle 545 from blocking the wind, and can prevent the influence on the pipeline installation position and reduce the difficulty of mold processing.

[0096] Reference Figure 3 、 Figure 4 and Figure 5 In some embodiments, the bracket 5 includes a support plate 56, the edge of the support plate 56 is provided with a side plate 57 which is substantially perpendicular to the support plate 56 and extends away from the support plate 56, the side plate 57 is arranged on the plate surface 561 of the support plate 56, and the plate surface 561 inside the side plate 57 is provided with a rib plate 55 for strengthening the strength of the bracket 5.

[0097] The maximum thickness D of the bracket 5 is substantially equal to the thickness of the support plate 56 and the height of the side plate 57.

[0098] In the embodiments of the present disclosure, the height of the baffle 545 refers to the distance from the side edge of the baffle 545 connected to the support plate 56 to the side edge away from the support plate 56. Similarly, the height of the rib plate 55 refers to the distance from the side edge of the rib plate 55 connected to the support plate 56 to the side edge away from the support plate 56.

[0099] In some embodiments, the drainage groove 54 is arranged on the bracket 5, and baffles 545 are arranged on both sides of the drainage groove 54. The baffles 545 also have the effect of reinforcing ribs, which are used to improve the strength of the bracket 5. Moreover, the baffles 545 of the drainage groove 54 are also connected to multiple rib plates 55, which greatly improves the strength of the drainage groove 54 and prevents the baffles 545 of the drainage groove 54 from breaking.

[0100] In some embodiments, the height of the baffle 545 is higher than the height of the rib plate 55, so that the condensed water flows into the drainage groove 54 more smoothly; and the baffle 545 can also serve as a reinforcing rib to strengthen the strength of the bracket 5.

[0101] In some embodiments, the height of the rib plate 55 is greater than or equal to 3 mm and less than 21 mm.

[0102] Since the height of the rib plate 55 is generally 2 mm, the baffle 545 is at least 1 mm higher than the rib plate 55. The maximum thickness D of the bracket 5 is 21 mm, and the height of the baffle 545 is less than or equal to the maximum thickness D of the bracket 5.

[0103] In some embodiments, the drainage groove 54 adopts a draft + fillet design.

[0104] The entire bracket 5 is an injection molded part. The drainage channel 54 adopts a draft mold design with rounded corners. The draft mold design makes the bracket 5 easier and more convenient to demold, while the rounded corner design makes the drainage channel 54 stronger and prevents it from breaking under stress. Both designs ensure that the bracket 5 and the drainage channel 54 can be machined as a single piece during production, without the need to add other parts to drain water, thus reducing the number of parts, reducing labor costs, and improving production efficiency.

[0105] In some embodiments, both the first heat exchanger 1 and the second heat exchanger 2 can be fixed to the bracket 5 by screws, for example, fixed to... Figure 4 The bracket 5 shown is fixed securely on its first inclined side 511 and second inclined side 521, and the method is simple and easy to use for production operations.

[0106] In some embodiments, the bracket 5 is close to the shell and the second water receiving tray 4, which can simultaneously support the unit structure and play a decisive role in the drop and trampling tests of the unit.

[0107] refer to Figure 8 and Figure 9 The first water receiving tray 3 has a notch 31 at its end, which connects the first water receiving tray 3 and the drain trough 54. The notch 31 at the end of the first water receiving tray 3 allows condensate to flow out smoothly.

[0108] In some embodiments, the first water receiving tray 3 may have a notch 31 at one end and be closed at the other end. Alternatively, both ends of the first water receiving tray 3 may have notches 31.

[0109] If a notch 31 is provided at one end of the first water receiving tray 3, a drainage groove 54 is provided on the bracket 5 at that end of the first water receiving tray 3. Condensate can only be discharged from the end of the first water receiving tray 3 with the notch 31, which is low cost.

[0110] The first water receiving tray 3 has notches 31 at both ends, and drainage grooves 54 are provided on the supports 5 at both ends of the first water receiving tray 3, so that water can be drained from both ends and the drainage rate is high.

[0111] In some embodiments, the first drip tray 3 is an injection molded part.

[0112] In some embodiments, the width of the notch 31 in the first water receiving tray 3 is slightly smaller than the width of the inside of the drain groove 54 of the bracket 5, so as to ensure that all the condensate flows into the drain groove 54 and prevents the condensate from overflowing.

[0113] In some embodiments, the first heat exchanger 1 and the second heat exchanger 2 are symmetrically arranged, the first heat exchanger 1 is above the second heat exchanger 2, the first heat exchanger 1 and the second heat exchanger 2 are both arranged obliquely, the bottom of the first heat exchanger 1 is adjacent to the top of the second heat exchanger 2, and the top of the first heat exchanger 1 and the bottom of the second heat exchanger 2 are both inclined upstream. A first water pan 3 is arranged between the first heat exchanger 1 and the second heat exchanger 2. A second water pan 4 is arranged below the second heat exchanger 2.

[0114] When the first heat exchanger 1 is normally working, the condensed water enters the first water pan 3 along the fins. Since the end of the first water pan 3 is provided with a notch 31, the condensed water can smoothly pass through the notch 31 and enter the drainage groove 54 on the support 5. By using the adsorption characteristics of the condensed water itself, the condensed water will flow along the drainage groove 54 on the support 5 and will not flow through other paths, so as to drain the condensed water. At the same time, by using the gravity effect, the water will naturally flow from high to low, so as to meet the requirement that the condensed water will finally be drained along the drainage groove 54 on the support 5. Finally, the condensed water will flow into the second water pan 4 and be normally drained from the unit along with the work of the liquid level switch-water pump.

[0115] Some embodiments of the present disclosure also provide an air conditioner comprising the heat exchange assembly in any of the above embodiments.

[0116] Since the air conditioner comprises the heat exchange assembly in any of the above embodiments, the air conditioner has the beneficial effects of the heat exchange assembly.

[0117] In some embodiments, the air conditioner comprises a temperature control and dehumidification air pipe machine.

[0118] In some embodiments, the heat exchange assembly is an indoor heat exchange assembly of the air conditioner.

[0119] In some embodiments, the heat exchange assembly comprises the first heat exchanger 1 and the second heat exchanger 2, and the first heat exchanger 1 is arranged above the second heat exchanger 2.

[0120] In the temperature control and dehumidification mode, the first heat exchanger 1 is used for dehumidification, and the second heat exchanger 2 is used for heat exchange.

[0121] When the condensed water generated by the first heat exchanger 1 drops onto the second heat exchanger 2, it will affect the heat exchange effect of the second heat exchanger 2, so the first water pan 3 is arranged to receive the condensed water. The drainage groove 54 is arranged on the support 5, and the condensed water in the first water pan 3 is drained through the support 5, which can reduce the parts of the unit, does not need to fix a drainage device for drainage, completes the miniaturization of the shell design, and reduces the assembly efficiency of production. Finally, the condensed water generated by the first heat exchanger 1 and the second heat exchanger 2 flows into the second water pan 4 together. When the water level in the second water pan 4 exceeds the working height of the liquid level switch, the water in the second water pan 4 is pumped out through the drainage pipe connected with the water pump.

[0122] Based on the above-mentioned embodiments of the present disclosure, the technical features of one of the embodiments can be beneficially combined with one or more of the other embodiments without explicit negation or conflict.
