A front water cooling section and a rear water cooling section are set along the paper sheet movement direction, and a heat dissipation air blower is set between the front and rear cold water sections. In its structure, a heat dissipation roller, a water tank, a heat dissipation air blower, and a temperature detector are symmetrically arranged up and down along the paper sheet, so that the cooling speeds on both sides of the paper sheet are consistent and balanced, and the internal structure of the paper sheet is not damaged. A temperature detector is set between the rear water cooling section and the air cooling section to control the rotation speed of the variable frequency speed regulating water pump in the rear water cooling section, thereby controlling the water flow rate of the water circulation water body, further ensuring consistent double-sided cooling, sufficient cooling, and avoiding energy waste.

[0004] When producing cardboard, a heat dissipation device is used to cool down the equipment for producing cardboard, and the heat dissipation device for cardboard production equipment is one of them.
