Preferably: and the temperature sensor and the water pump are respectively and electrically connected with the industrial personal computer.

Preferably: the radiating fins are copper sheets or aluminum sheets.

Preferably: and a plurality of heat dissipation holes are formed in the side wall, far away from the cooling chamber, of the heat dissipation cover.

The beneficial effect of adopting above technical scheme is:

when the temperature sensed by the temperature sensor is higher than a set value, cold water in the water tank is filled into the cooling chamber by the water pump, the cold water moves in a snake shape in the cooling chamber and flows out of the water outlet pipe to cool the radiating fins, and the radiating fins continuously absorb heat of the shell of the silencer, so that the radiating purpose is realized;

the purpose of natural heat dissipation can be achieved through the heat dissipation holes.
