Description

Technical Field

[0001] The utility model relates to the technical field of wind generators, in particular to a heat dissipation structure of a wind generator. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of a wind rotor, a generator (including a device), a stabiliser (tail), a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, converting the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity under the drive of the wind rotor shaft.

[0003] When a wind turbine is continuously rotating, the temperature of the generator inside it will gradually rise, generating more heat. A heat dissipation structure of a wind turbine is now designed, which can remove the heat generated by the generator. Utility Model Content
