[0032] Working principle:

[0033] During use, the hot liquid that needs to be cooled is transferred through the hot liquid pipe 15 to the cooling coil 19 inside the wet area of ​​the cooling base box 1. At the same time, the water pump 10 is started to transfer the water accumulated inside the cooling base box 1 to the spray box 4. The water is sprayed through the spray device 16 and spray head 17 inside the spray box 4, thereby spraying and cooling the outer side wall of the cooling coil 19. The cooled liquid inside the cooling coil 19 is transferred to the designated location through the cold liquid pipe 14, thereby completing the cooling operation.

[0034] The liquid sprayed by the spray head 17 is filtered by multiple sets of cleaning components 18 inside the cooling base box 1, thereby effectively filtering the sprayed coolant in multiple layers and avoiding the accumulation of sediment and impurities inside the cooling base box 1, which would prevent effective spraying circulation.

[0035] By cleaning the multiple sets of support partition columns 32 spaced apart on the component 18, it is possible to effectively prevent the two vertically adjacent filter screens 31 from sticking together due to liquid impact, which would prevent the effective conduction of spray liquid.

[0036] By using two sets of vertically arranged fan blades 27 inside the dry zone of the cooling base box 1, the heat generated by the cooling of the wet zone inside the cooling base box 1 can be effectively dissipated, thereby effectively improving the cooling effect of the wet zone inside the cooling base box 1.

[0037] With the fan blades 27 arranged in a double layer, dual airflow guidance is achieved, enabling faster cooling and heat dissipation of the humid area inside the cooling base box 1.

[0038] The internal fan 33 installed inside the auxiliary cooling box 20 dries the liquid on the cooling coil 19, thereby better cooling the cooling coil 19 and improving the cooling efficiency of the cooling coil 19.

[0039] By setting an elastically adjustable liquid-blocking plate 24 inside the heat dissipation holes 23 on the isolation plate 22, the liquid in the wet area inside the cooling base box 1 can be effectively blocked from being conducted to the dry area, thereby improving the dry and wet separation effect inside the cooling base box 1.
