The processing part can collect the scale precipitated in the cooling water and facilitate cleaning.

[0019] The second heat exchange tube 5 of the utility model is spiral-shaped, a water injection port is provided on the surface of the water tank 9, and cooling water is provided inside the first heat exchange tube 2, the second heat exchange tube 5 and the water tank 9.

[0020] The fan blades 8 of the utility model correspond to the water tank 9 , and a plurality of heat dissipation fins are arranged on the surface of the water tank 9 , and the plurality of heat dissipation fins are linearly distributed on the surface of the water tank 9 .

[0021] The filter screen of the utility model is tilted from high to low from the side close to the mounting sleeve 22 to the side away from the mounting sleeve 22. The connecting rod 20 and the paddle 23 are respectively located on both sides of the mounting sleeve 22.

[0025] Working principle: Figure 1 As shown, the first water pump 15 allows the cooling water to circulate in the first heat exchange tube 2 and the second heat exchange tube 5. When the cooling water is in the first heat exchange tube 2, it exchanges heat with the equipment body 1 to cool it. When the cooling water is in the second heat exchange tube 5, it exchanges heat with the cooling water in the heat exchange box 4 to cool it down. The second water pump 14 allows the cooling water to circulate in the water tank 9, the water outlet pipe 6, the heat exchange box 4, and the water inlet pipe. When the cooling water is in the heat exchange box 4, it exchanges heat with the cooling water in the second heat exchange tube 5. When the cooling water is in the water tank 9, it exchanges heat with the air. At the same time, the second water pump 14 drives the first sprocket to rotate, the first sprocket drives the second sprocket to rotate through the chain 13, and the second sprocket drives the fan blade 8 to rotate through the second rotating shaft 11, thereby accelerating the air flow around the water tank 9 and improving the heat exchange efficiency. Figure 2 As shown, when the cooling water enters the treatment box 3, the scale will be blocked by the first filter 19 and enter the storage box 25 along the first filter 19 through the outlet and the first opening until it is blocked by the second filter 24, while the cooling water passes through the second filter 24 and returns to the treatment box 3 through the inlet. At the same time, the cooling water drives the paddle 23 to move, causing the first rotating shaft 21 to rotate, and the first rotating shaft 21 drives the connecting rod 20 to rotate, and the connecting rod 20 drives the ball to intermittently move the first filter 19 to prevent scale from accumulating on the surface of the first filter 19. When it is necessary to clean the scale, pull the limit rod 17 to the right to disengage it from the storage box 25, and lift the storage box 25 horizontally. The scale stays in the storage box 25 due to the obstruction of the slope 16, and the scale can be taken out. The storage box 25 is rotated clockwise so that the scale rolls out of the storage box 25 from the first opening under the action of gravity, thereby achieving scale cleaning.
