The surface of the rotating shaft 20 is provided with a thread, and the rotating shaft 20 is arranged horizontally. One end of the rotating shaft 20 is movably arranged on the side wall of the heat exchange device 1, and the other end passes through the side wall of the heat exchange device 1 and is connected to the motor 21 at the end. The auxiliary shaft 22 is arranged parallel to the rotating shaft 20. The two ends of roller 22 are fixed on the two inner walls of heat exchange device 1, the first movable block 230 and the second movable block 231 are respectively arranged at the two ends of roller 23, the first movable block 230 is connected to the rotating shaft 20 by setting a threaded hole, the second movable block 231 is connected to the auxiliary shaft 22 by setting a through hole, a plurality of grooves 232 are evenly arranged on the surface of roller 23 along the axial direction, the brush plate 24 is detachably arranged in the groove 232, one end of the brush plate 24 can contact the bottom wall of heat exchange device 1, a water inlet 300 is arranged on the top of collecting component 3, the heat exchange device 1 and collecting component 3 are connected with the water inlet 300 through the first drain port 100.

[0041] The motor 21 drives the rotating shaft 20 to rotate in the heat exchange device 1, and then drives the first moving block 230 to move on the rotating shaft 20. The brush plate 24 drives the roller 23 to rotate while contacting the bottom surface of the heat exchange device 1, which can drain the bottom water in the heat exchange device 1 to the first drain port 100. The main function of the brush plate 24 rotating in the heat exchange device 1 is to prevent impurities in the accumulated water from condensing and sinking to the bottom, making it difficult to clean.

[0042] In this embodiment, a first connecting flange 110 is provided at the lower edge of the first drain outlet 100, and a second connecting flange 301 is provided at the upper edge of the water inlet 300. The heat exchange device 1 and the collecting component 3 are connected via the first connecting flange 110 and the second connecting flange 301, thereby increasing the sealing performance of the connection between the collecting component 3 and the heat exchange device 1.

[0043] In this embodiment, the collecting assembly 3 includes: a collecting box 30, a filter screen 31, and a water inlet pipe 32. A water inlet 300 is arranged on the top of the collecting box 30, a second drain port 302 is arranged on the bottom of the collecting box 30, and a third drain port 303 is arranged on the side wall of the collecting box 30 near the upper end.

The umbrella-shaped baffle 321 enables the water in the water inlet pipe 32 to flow evenly into the collection box 30. The impurities in the accumulated water are precipitated in the collection box 30. When the water flow in the collection box 30 gradually increases, the water in the collection box 30 can pass through the filter mesh plate 31 and enter the upper layer of the filter mesh plate 31 and be discharged from the third drain port 303.
