[0039] The heat exchange assembly includes a unit body 1, a coil 103 located in the unit body 1, an air outlet 101 located on the side of the unit body 1, and a ventilation plate 106 located in the air outlet 101, wherein the ventilation plate 106 has a ventilation hole;

[0040] A cleaning component 4, at least partially located in the air outlet 101, the cleaning component 4 comprises a cleaning brush 401, and the cleaning brush 401 can move along the extension direction of the ventilation plate 106;

[0041] The fan assembly is connected to the end of the unit body 1. The fan assembly and the air outlet 101 are located on opposite sides of the unit body 1. The fan assembly is used to transfer air in the external environment to the heat exchange assembly.

[0042] Specifically, the fan assembly includes at least one fan 2, and the fan 2 in the fan assembly is connected to the unit body 1 in the heat exchange assembly. The fan assembly can transmit the control in the external environment (i.e., outdoor) to the unit body 1 in the heat exchange assembly. The unit body 1 includes a shell and a accommodating cavity surrounded by the shell.

The cleaning component 4 is located in the air outlet 101, and the cleaning brush 401 in the cleaning component 4 is released from the ventilation plate 106, and the cleaning brush 401 can move on the surface of the ventilation plate 106 along the extension direction of the ventilation plate 106, so that the dust accumulated on the ventilation plate 106 (for example, the dust accumulated in the vent in the ventilation plate 106) is removed by brushing with the cleaning brush 401, so as to clean the heat exchange component, reduce the accumulation of dust on the ventilation plate of the heat exchange component, and thus improve the heat exchange effect and air outlet performance of the heat exchange component.

[0043] In some embodiments, the heat exchange assembly also includes a fixed frame 102, a water supply port 104 and a return water port 105 both located in the fixed frame 102, and a condensate tray 201 located below the unit body 1. The fixed frame 102 is at least arranged at the end of the unit body 1 and is fixedly connected to the unit body 1. One end of the coil 103 is connected to the water supply port 104, and the other end is connected to the return water port 105.

[0044] For example, if Figure 1-Figure 3 As shown, the fan assembly is located at the end of the unit body 1 along the first direction D1, and the fixing frame 102 is located at the end of the unit body 1 along the second direction D2, wherein the first direction D1 and the second direction D2 are both horizontal directions, and the first direction D1 intersects with the second direction D2 (for example, vertically intersects or obliquely intersects). Cooling water or hot water enters the coil 103 through the water supply port 104, and after heat exchange with the air in the unit body 1, it flows out from the water return port 105 for recycling. The condensate tray 201 is located below the unit body 1 and is used to collect condensed water generated during the heat exchange process.

[0045] In some embodiments, the cleaning brush 401 includes a bristle surface and a back surface that are relatively distributed along a first direction D1; the cleaning component 4 also includes:

[0046] An arc-shaped sleeve 402 is disposed on the back of the cleaning brush 401, and the inner wall of the arc-shaped sleeve 402 has threads;

[0047] A threaded rod 405, threadedly connected in the arc-shaped sleeve 402, and the threaded rod 405 crosses the air outlet 101 at least along a second direction D2, and the second direction D2 intersects the first direction D1;

[0048] The rotating motor 404 is rotatably connected to the side of the unit body 1 , and the rotating motor 404 is connected to the end of the threaded rod 405 , and the rotating motor 404 can drive the threaded rod 405 to rotate.

[0049] In some embodiments, the air outlet 101 has first rotating holes on the two inner side walls relatively distributed along the second direction D2, the threaded rod 405 is rotatably connected to the two first rotating holes at both ends along the second direction D2, and the rotating motor 404 is connected to one end of the threaded rod 405 extending out of the first rotating hole.

[0050] For example, if Figure 1-Figure 4 As shown, the cleaning component 4 includes a cleaning brush 401, and the cleaning brush 401 includes a bristle surface with bristles and a back surface opposite to the bristle surface along the first direction D1. In one example, the bristles can be long rubber bristles to avoid damaging the ventilation plate 106. The arc sleeve 402 is fixedly connected to the back surface of the cleaning brush 401, and the inner wall of the arc sleeve 402 has a thread. The threaded rod 405 is sleeved in the arc sleeve 402, and the threaded rod 405 is threadedly connected to the arc sleeve 402. The threaded rod 405 extends along the second direction D2 and passes through the air outlet 101 along the second direction D2. The air outlet 101 has first rotating holes on both inner side walls that are relatively distributed along the second direction D2. The two ends of the threaded rod 405 are rotatably connected to the two first rotating holes along the second direction D2. The rotating motor 404 is connected to one end of the threaded rod 405 extending out of one of the first rotating holes. The other end of the threaded rod 405 extending out of the other first rotating hole is connected to a nut to prevent the threaded rod 405 from slipping out of the first rotating hole. The rotating motor 404 is located outside the unit body 1 along the second direction D2, and the rotating motor 404 is connected to the end of the threaded rod 405.

[0051] When the ventilation plate 106 in the heat exchange assembly needs to be cleaned, the threaded rod 405 is driven to rotate by the rotating motor 404. The rotation of the threaded rod 405 drives the arc sleeve 402 sleeved on the threaded rod 405 to translate along the extension direction (i.e., the second direction D2) of the threaded rod 405. The movement of the arc sleeve 402 drives the cleaning brush 401 to move along the second direction, so that dust and other impurities on the surface of the ventilation plate 106 are removed through the contact and friction between the cleaning brush 401 and the ventilation plate 106, so as to clean the ventilation plate 106, thereby improving the air outlet efficiency and heat exchange effect of the heat exchange assembly.

[0052] In some embodiments, the rotating motor 404 and the fixing frame 102 are located on the same side of the unit body 1. In one example, the rotating motor 404 and the fixing frame 102 are both located at the same end of the unit body 1 along the second direction D2, so as to facilitate connecting an external structure (such as a cooling water source or a power source) on the same side of the unit body 1.

[0053] In some embodiments, the cleaning component 4 further includes:

[0054] The limit block 403 is connected to the end of the cleaning brush 401 along the third direction D3, and the limit block 403 is slidably connected to the top of the air outlet 101, and the third direction D3 intersects both the first direction D1 and the second direction D2. By setting the limit block 403 on the top of the cleaning brush 401, and the limit block 403 is slidably connected to the top of the air outlet 101, on the one hand, it is ensured that the cleaning brush 401 slides along the extension direction of the air outlet 101 (i.e., the second direction D2); on the other hand, it can also limit the position of the cleaning brush 401 in the air outlet 101, further ensuring that the cleaning brush 401 can fully contact the ventilation plate 106, thereby further improving the effect of the cleaning brush 401 cleaning the ventilation plate 106. The third direction D3 can be a vertical direction.

[0056] The adjusting component 3 is located in the air outlet 101 , and the adjusting component 3 is arranged on a side of the cleaning component 4 away from the ventilation plate 106 . The adjusting component 3 is used to adjust the air outlet angle of the air outlet 101 .

[0057] In some embodiments, the adjustment component 3 includes:

[0058] An air guide plate 301 is located on a side of the cleaning component 4 away from the ventilation plate 106, and the air guide plate 301 is movably connected to the air outlet 101;

[0059] A rotating rod 304 is fixedly connected to the end of the air guide plate 301 along the first direction D1, and the rotating rod 304 extends along the second direction D2;

[0060] A lifting sleeve 305 is located in the air outlet 101 and connected to the end of the air guide plate 301 along the second direction D2. The inner wall of the lifting sleeve 305 has threads.

[0063] The bevel gear motor 308 is located at the end of the bevel gear rod 307 along the third direction D3, and the bevel gear motor 308 is meshed and transmission-connected with the bevel gear rod 307.

[0064] Specifically, the end of the wind deflector 301 along the first direction D1 is fixedly connected with the rotating rod 304, and the rotating rod 304 extends along the second direction D2. The two lifting sleeves 305 are distributed on opposite sides of the wind deflector 301 along the second direction D2, and each lifting sleeve 305 has the arc plate 306 on the side facing the wind deflector 301. The two pairs of end portions of the rotating rod 304 along the second direction D2 are respectively rotatably connected to the through holes in the arc plates 306 on the sides of the two lifting sleeves 305. The two bevel gear rods 307 are sleeved in the two lifting sleeves 305 one by one. The bevel gear motor 308 located at the top of the bevel gear rod 307 is meshed and connected to the bevel gear rod 307. In an example, the adjustment component 3 includes only one bevel gear motor 308, and the bevel gear motor 308 is meshed and connected to only one bevel gear rod 307. In another example, the adjustment assembly 3 includes two bevel gear motors 308 , and the two bevel gear motors 308 are meshingly connected with the two bevel gear rods 307 one by one, and the two bevel gear motors 308 synchronously drive the two bevel gear rods 307 to rotate in the same direction.

[0065] When the air outlet angle of the air outlet 101 needs to be adjusted, the bevel gear motor 308 drives the bevel gear rod 307 connected to it for transmission meshing to rotate, and the bevel gear rod 307 drives the lifting sleeve 305 to move up and down in the vertical direction (i.e., the third direction D3) through the rotation of the bevel gear rod 307. The lifting and lowering movement of the lifting sleeve 305 drives the rotation of the rotating rod 304 on its side, and the rotation of the rotating rod 304 drives the rotation of the air guide plate 301. The rotation of the air guide plate 301 changes the air outlet angle of the air outlet 101, thereby realizing the adjustment of the air outlet direction of the air outlet 101.

[0070] Specifically, the second rotating holes 107 are provided on the inner side walls of the air outlet 101 on opposite sides along the second direction D2, and the second rotating holes 107 do not penetrate the housing along the second direction D2.
