Description

Technical Field

[0001] The utility model relates to the technical field of wind power brake heat dissipation, and in particular to a brake heat dissipation mechanism. Background Art

[0002] When a wind turbine is running, the rotation of the blades drives the speed increaser and the high-speed shaft to rotate, and then the generator is used to generate electricity. When the blades rotate too fast, the huge weight of the blades will cause the wind turbine to lose stability. Therefore, a brake system is needed to control the rotation speed of the blades. However, during actual braking, a large amount of heat energy will be generated when the brake structure controls the speed of the rotating structure. This part of heat energy needs to be assisted in the heat dissipation by a brake heat dissipation mechanism to prevent the brake mechanism from overheating and affecting the blade speed control of the wind turbine.
