[0032] In this embodiment, the outer surface of the water tank 31 is connected to a drainage pipe 37 , and one end of the drainage pipe 37 away from the water tank 31 passes through the box body 1 and extends to the outside of the box body 1 .

[0033] In this embodiment, an electric-controlled valve 38 is installed on the outer surface of the drainage pipe 37 , and four support columns 6 are installed on the upper surface of the box body 1 . The top end of each support column 6 is connected to the bottom surface of the mounting plate 7 .

[0035] The working principle and use process of the present invention are as follows: when in use, first, the box body 1 is placed on the designated use site through the support pad 2 to ensure the stability of the equipment, and the water storage tank 31 is filled with water as a condensing medium, and is connected to the process material pipeline through the material feed pipe 24 to prepare for conveying the material to be cooled, and is connected to the cooling medium circulation system through the cooling discharge pipe 21 and the cooling feed pipe 20 to establish a circulation path for the cooling medium, and the material is conveyed to the inside of the heat exchange coil 22 through the material feed pipe 24 for heat exchange, and the shower pump 11 is started to draw water from the inside of the water storage tank 31, and is conveyed to the diversion pipe 17 and the shower head 18 through the filter box 13 and the conveying pipe 16 for spraying. At the same time, the cooling medium is conveyed to the inside of the cooling pipe 19 through the cooling discharge pipe 21, and circulates in the cooling pipe 19 to cool the water sprayed by the shower head 18. The cooled spray water covers the surface of the heat exchange coil 22, quickly takes away the heat, and cools the material. In the process of cooling, the water will evaporate into large The amount of water vapor is removed, and the unevaporated water flows back to the water storage tank 31 for recycling. The cooled material is discharged through the material discharge pipe 23 to complete the heat exchange process. The fan 36 is started to extract cold air from the outside through the ventilation hole 5. The extracted cold air contacts the water vapor evaporated from the heat exchange coil 22, so that part of the steam condenses into water droplets and falls back to the water storage tank 31 for collection. When the cold air passes through the heat exchange coil 22, it takes away the surface temperature to increase the cooling effect. The air carrying water vapor is transported to the inside of the drainage pipe 33, the collecting pipe 34 and the condensing pipe 35 through the fan 36. The refrigerator 32 is started to cool the water in the water storage tank 31, and the temperature of the drainage pipe 33, the collecting pipe 34 and the condensing pipe 35 is quickly reduced. The water vapor condenses into water droplets when passing through the low-temperature drainage pipe 33 and the condensing pipe 35, and the condensed water flows into the collecting pipe 34. Finally, the collected condensed water flows back to the water cycle inside the box body 1 through the reflux pipe 10 to achieve efficient use of water.
