SET
The present invention belongs to the technical field of wind power generation, specifically, to a cooling device for wind turbine and a wind power generator set.
The wind turbine is a device that converts wind energy into electricity, which mainly consists of blades, generator, mechanical components and electrical parts. The wind turbine is mainly divided into two types of horizontal axis wind driven generator and vertical axis wind driven generator according to the rotating shafts. Right now, most of the wind turbine industry is dominated by the horizontal axis wind driven generator. It is necessary to install a cooling box to assist the cooling of the electrical parts inside the cabin of the generator.
During operation, the wind power generator set will generate a lot of heat, which is fine in spring or winter when the temperature is relatively low. However, in summer, the temperature is high, and the hot weather often can cause poor cooling of the wind power generator set. Usually, the fault rate of the wind power generator set is increased in summer. In severe cases, a fire may be triggered, causing unforeseeable security incidents and economic loss. There's no good solutions for this inn the prior art. Because the space inside the cabin is quite large, it's hard to achieve good cooling effects in hot weather by using common air blowing equipment, such as fan or exhaust blower; it's also impossible to achieve cooling in a short period of time by using refrigeration equipment, for example an air conditioner. Moreover, the cooling cost will be too high by directly using air conditioners or other refrigeration equipment to cool the cabin.
Therefore, how to provide a cooling device for wind turbine and a wind power generator set that can dissipate heat rapidly is a problem to be solved by the technicians in this field.
The purpose of the present invention is to provide a cooling device for wind turbine and a wind power generator set that can achieve cooling rapidly. The present invention can achieve rapid cooling of the wind turbine and the cooling cost is reduced by using a multi-stage cooling method.
