A heat dissipation structure is installed at the top of the supporting hydraulic cylinder 3, and the heat dissipation structure is located on the generator body 2. The heat dissipation structure can more efficiently perform heat conduction and heat dissipation for the generator body 2, so that the generator body 2 can be cooled down faster and thus can effectively achieve a better heat dissipation effect for the generator body 2 to avoid overheating of the generator body 2; an auxiliary cooling structure is installed at the heat dissipation structure, and the auxiliary cooling structure is connected to the heat dissipation structure. The auxiliary cooling structure can be used to quickly cool down the generator body 2, further achieving a rapid heat conduction and heat dissipation effect, which is suitable for promotion and use.

The heat sink fan 8 is installed on the arc-shaped heat sink 4 . A plurality of heat sink fins 7 are arranged at equal intervals at the top of the arc-shaped heat sink 4 .

[0048] A contact heat sink 5 is provided between the arc-shaped heat sink 4 and the generator body 2 .

[0049] The outer surface of the generator body 2 is coated with thermal conductive silicone grease 6 , and the thermal conductive silicone grease 6 is located between the generator body 2 and the contact heat sink 5 .

[0051] The supporting fixed plate 9 is symmetrically arranged on the bottom plate of the arc-shaped heat dissipation plate 4, and a fixed pipe 10 is connected to the top of the supporting fixed plate 9. A plurality of spray nozzles 11 are arranged at intervals on the fixed pipe 10, and the spray nozzles 11 are connected to the fixed pipe 10 to form water mist and spray it onto the surface of the heat dissipation fins 7; a water tank 12 is arranged on the fixed bottom plate 1, and a liquid inlet pipe 14 is arranged inside the water tank 12, and a delivery pipe 15 is arranged outside the water tank 12, and an input end and an output end of a delivery pump 13 are respectively connected to one end of the liquid inlet pipe 14 and one end of the delivery pipe 15, and the other end of the liquid inlet pipe 14 is connected to the water tank 12, and the other end of the delivery pipe 15 is connected to the fixed pipe 10, and the water in the water tank 12 is transported to the fixed pipe 10 by the delivery pump 13, and water mist is formed by the spray nozzles 11 and sprayed onto the surface of the heat dissipation fins 7.
