Description

Technical Field

The other end of the first pipe 8 is connected to a water pump 9, and the first pipe 8 is connected to the water inlet of the water pump 9. The coolant in the cooling water tank 7 enters the water pump 9 through the first pipe 8. The other end of the water pump 9 is connected to a second pipe 10, and the second pipe 10 is connected to the water outlet of the water pump 9. The water pump 9 pumps the coolant entering therein into the second pipe 10. A heat dissipation component 12 is fixedly installed at the bottom of the mounting groove 6, and one end of the second pipe 10 away from the water pump 9 is connected to the heat dissipation component 12. A spiral coil 11 is also fixedly installed inside the silencing chamber 4, and both ends of the spiral coil 11 are inserted into the mounting groove 6, and the inserted two ends are respectively connected to the cooling water tank 7 and the heat dissipation component 12. In the process of the coolant passing through the spiral coil 11, the heat generated in the silencing cotton 5 can be taken away by heat exchange.

[0022] Among them, the heat dissipation component 12 includes a water distribution tank 1201 and a water collection tank 1202 fixedly installed at the bottom of the installation groove 6, and a plurality of heat dissipation tubes 1203 are arranged in an array between the opposite sides of the water distribution tank 1201 and the water collection tank 1202. The coolant entering the water collection tank 1202 flows evenly into each heat dissipation tube 1203, so that the heat is evenly distributed. The heat dissipation component 12 also includes heat dissipation plates 1204 arranged in sequence between the water distribution tank 1201 and the water collection tank 1202. The plurality of heat dissipation tubes 1203 all pass through the plurality of heat dissipation plates 1204 in sequence, and the heat dissipation plates 1204 and the heat dissipation tubes 1203 are welded and connected, and the contact area between the heat dissipation tubes 1203 and the air is increased by the heat dissipation plates 1204, thereby improving the heat dissipation efficiency.

[0023] Among them, the second pipe 10 is connected to the water distribution tank 1201, the spiral coil 11 is connected to the water collection tank 1202, and the water pump 9 pumps the coolant with heat into the water distribution tank 1201.

[0027] Specific working principle:

[0028] During the use of the utility model, it is necessary to connect the utility model to an external power supply and a control panel. During the use of the utility model, the noise generated when the generator rotor rotates enters the silencer chamber 4 through the various through holes of the rotor chamber 3, and the noise is weakened by the silencer cotton 5 arranged in the silencer chamber 4, thereby achieving the effect of reducing noise. In this process, the heat energy generated when the silencer cotton 5 weakens the noise is conducted to the coolant through the spiral coil 11. Under the operation of the water pump 9, the coolant continuously delivers heat to the various heat sinks 1204 in the heat sink assembly 12. At the same time, the operation of the heat sink fan 16 can effectively increase the air flow rate near the heat sink 1204, thereby taking away the heat on the heat sink 1204, thereby achieving effective heat dissipation of the heat sink cotton.
