Abstract

The invention provides a wind generating set. The wind generating set comprises a heat dissipation system arranged in a cabin. The heat dissipation system comprises an air inlet formed in the side wall of the cabin and used for introducing outside air into the cabin; the air outlet is formed in the bottom wall of the cabin; one end of the first exhaust pipeline is communicated with the interior of the generator; an inlet of the cooling fan is communicated with the other end of the first exhaust pipeline; and one end of the second exhaust pipeline is communicated with an outlet of the cooling fan, and the other end of the second exhaust pipeline is communicated with the air outlet. According to the wind generating set, heat can be effectively dissipated, the length of the cabin cover can be shortened, the weight of the cabin can be reduced, the load and the cost of the set can be controlled, and the reliability of the set can be ensured by adopting a side air inlet and bottom air outlet mode.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more particularly, to a wind power generator set. Background technique [0002] As the power of the wind turbine increases, the calorific value of the generator increases. Therefore, the cooling system of the generator needs to effectively dissipate heat to ensure the operating efficiency of the generator and the service life of each component. The air outlet pipes used in the generator cooling system of the prior art are generally relatively long, which affects the cooling effect of the generator. [0003] In addition, in order to improve the heat dissipation effect, it is necessary to select a cooling fan with a higher air volume, but such a cooling fan will generate more noise. At present, there are international requirements for the noise control of the unit, and the domestic unit also needs to be controlled according to the use environment. noise. With the use of ...
