[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind is a pollution-free energy source. Using wind power for power generation is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. Wind power generation devices are often protected by covers during use.
[0003] Among them, the "wind turbine generator set with adjustable cabin temperature" disclosed in the application number "CN202223284369.9" is also an increasingly mature technology, which "comprises a tower, a cabin cover is connected to the tower, one end of the cabin cover is connected to a hub, blades are connected to the hub, a gearbox and a generator are installed in the cabin cover, and the hub, gearbox and generator are connected in sequence; a gearbox radiator is installed on the gearbox, and a gearbox heat dissipation duct is connected to the gearbox radiator; a generator radiator is installed on the generator, and a generator heat dissipation duct is connected to the generator radiator. The utility model provides a wind turbine generator set with adjustable cabin temperature", the application number is "CN202223284369.9". The "nacelle cover of a wind turbine generator set and a wind turbine generator set" disclosed in the patent application number "CN201420785536.4" solves the technical drawbacks of "the existing heat dissipation method, whose power device consumes a lot of electric energy and generates heat itself, so its heat dissipation efficiency cannot meet the requirements, especially for wind turbines located in tropical areas or in the hot summer season, under continuous full-power conditions, the generator, electrical components, yaw, brakes, bearings and the power system of the heat exchange device itself will generate a lot of heat. At this time, the heat exchange capacity is insufficient, which may cause the unit to alarm and shut down". However, the above two public technologies still have the following defects during use:
[0004] The wind turbine generator set covers in the above two disclosed devices are not provided with a heat insulation structure. Since the wind turbine generator set covers are often exposed to the outside for use, the heat energy absorbed by them under the action of solar radiation for a long time is conducted to the inside of the unit through the cover, causing the temperature of the air inside the unit to rise, so that the heat of the main components inside the unit (such as the generator, gearbox, pitch system, etc.) is difficult to dissipate quickly and effectively.

Then, the second water pump switch on the surface of the switch panel 15 is turned on, and the pumping end of the second water pump 45 guides the water source carrying heat into the return pipe 46, and then guides the water source back to the cooling chamber 3 through the water outlet end of the second water pump 45.
