[0032] By providing the spiral tube 400 and the exhaust hole 401 , the air injected by the blower 402 can be discharged from the spiral tube 400 in layers, thereby cooling down the hot air on the top of the cooling tank 100 .

[0033] The present solution has the following working process: when cooling the hot air, first start the motor 500, the motor 500 rotates to drive the first gear 501 to rotate, the first gear 501 rotates to drive the second gear 502 to rotate, the second gear 502 rotates to drive the butt joint pipe 102 connected thereto, and then drives the top cooling network pipe 101 to rotate, and drives the bottom cooling network pipe 101 to rotate through the transmission of the pulley 600 and the belt 601, starts the water pump 700, and the water pump 700 pumps the water in the water tank 703 into the connecting pipe 104, and then enters the two cooling network pipes 101 respectively, and then discharges from the second installation pipe 702 into the water tank 703, starts the hot air exhaust device, and the hot air exhaust device discharges the hot air into the intake pipe 205, and then enters the first distribution pipe 206. The hot air is finally discharged from the space between the air pipe, the second air branch pipe, the third air branch pipe and the fourth air branch pipe and passes through the two cooling mesh pipes 101 in sequence. The hot air contacts the cooling mesh pipe 101, which cools the hot air so that the hot air condenses to form water droplets attached to the surface of the cooling mesh pipe 101. The cooling mesh pipe 101 rotates so that both sides of the cooling mesh pipe 101 can contact the hot air. At the same time, the water droplets on the surface of the cooling mesh pipe 101 are thrown onto the inner wall of the cooling tank 100 under the action of centrifugal force and finally discharged from the drainage hole 301. The hot air discharge device is started and the blower 402 is started at the same time. The blower 402 injects air into the spiral tube 400, which is finally discharged from the exhaust hole 401 in layers to cool the small amount of hot air at the top of the cooling tank 100.

[0034] According to the above working process, it can be known that: by setting up the cooling network pipe 101, the hot air can be cooled when passing through the cooling network pipe 101, thereby improving the cooling effect; by setting up the first connecting pipe 103, the second connecting pipe 106, the motor 500, the first gear 501, the second gear 502, the pulley 600 and the belt 601, the two cooling network pipes 101 can be rotated, so that both sides of the cooling network pipe 101 can contact with the hot air, further improving the cooling effect of the hot air, thereby increasing the contact area between the hot air and the cooling network pipe 101, thereby improving the cooling effect of the hot air.

[0035] By setting the spiral tube 400 and the exhaust hole 401, after the blower 402 injects air into the spiral tube 400, the air can be discharged from the exhaust hole 401 in layers to the top position of the cooling tank 100, so that a small amount of hot air at the top of the cooling tank 100 can be cooled, further improving the cooling effect of the hot air.

Pulleys 600 are respectively fixed to the outer walls of the docking tube 102 on the other side of the top and the bottom, and a belt 601 is rotatably connected between the two pulleys 600.

[0040] The two cooling network pipes 101 can rotate synchronously by means of the provided pulley 600 and the belt 601 , and the top cooling network pipe 101 can rotate by means of the provided motor 500 , the first gear 501 and the second gear 502 .

[0041] Further as Figure 4 As shown, a bottom cover 300 is fixed to the bottom surface of the cooling tank 100 , and a plurality of circumferentially distributed drainage holes 301 are opened on the bottom surface of the bottom cover 300 . An air intake pipe 205 is fixed to the bottom surface of the first air distribution cover 200 , and the air intake pipe 205 passes through the bottom cover 300 .

[0044] By means of the water pump 700 , the water in the water tank 703 can be pumped into the top and bottom cooling network pipes 101 respectively, thereby cooling the hot air entering the cooling tank 100 .

[0045] In summary, when the hot air is cooled, the motor 500 is first started. The rotation of the motor 500 drives the first gear 501 to rotate. The rotation of the first gear 501 drives the second gear 502 to rotate. The rotation of the second gear 502 drives the butt joint pipe 102 connected thereto, thereby driving the top cooling mesh pipe 101 to rotate.

The water pump 700 pumps the water in the water tank 703 into the connecting pipe 104, and then respectively enters the two cooling mesh pipes 101, and then is discharged from the second installation pipe 702 into the water tank 703. The hot air exhaust device is started. The hot air exhaust device discharges the hot air into the air inlet pipe 205, and then enters the first air distribution pipe, the second air distribution pipe, and the second air distribution pipe. The hot air is finally discharged from the space between the second air branch pipe, the third air branch pipe and the fourth air branch pipe and passes through the two cooling network pipes 101 in sequence. The hot air contacts the cooling network pipe 101, which cools the hot air so that the hot air condenses to form water droplets attached to the surface of the cooling network pipe 101. The cooling network pipe 101 rotates so that both sides of the cooling network pipe 101 can contact the hot air. At the same time, the water droplets on the surface of the cooling network pipe 101 are thrown onto the inner wall of the cooling tank 100 under the action of centrifugal force and finally discharged from the drainage hole 301. The hot air discharge device is started and the blower 402 is started at the same time. The blower 402 injects air into the spiral tube 400, which is finally discharged from the exhaust hole 401 in layers to cool the small amount of hot air at the top of the cooling tank 100.
