The invention discloses a heat dissipation device for
power equipment, and relates to the technical field of
power equipment. The heat dissipation device comprises a heat dissipation box, a water tankis mounted at the top of the heat dissipation tank and is connected with a water outlet
pipe, and the water outlet
pipe is connected with a pressure water pump. The pressure water pump is connected with a gasification
pipe, the gasification pipe is connected with a
liquefaction device, and the liquefying device is connected with a
branch pipeline. The
branch pipeline is connected with a refrigerator, the refrigerator is connected with an annular
water pipe, and the annular
water pipe is connected with a water return pipe. The water return pipe is connected with a
water supply pump, the watersupply pump is connected with the water tank, a suction fan is mounted on the surface of the right side wall of the heat dissipation box, and an
air cooling device is mounted on the left side wall ofthe heat dissipation box. The water tank, the water outlet pipe, the pressure water pump, the annular
water pipe, the
water supply pump and the water return pipe are arranged to form a
water circulation system, and the suction fan, an air exhaust adjusting box and the fan are arranged to form an air circulation
system, so that the air in the heat dissipation box can fully flow. Through the mutual combination of the
water circulation and the air circulation, the
power equipment in the heat dissipation box are cooled.
