Wind power generator system and fluid transportation apparatus

Abstract

The invention provides a wind power generator system. According to the wind power generator system, multi-phase flows entering the generator can be separated to reduce moisture and impurities entering the generator so as to improve the insulating performance of the generator while a cooling effect is achieved, and to reduce abrasion for a heat exchanging surface of the internal cavity of the generator. The wind power generator system comprises the generator with a motor cavity and blades connected with the rotor of the generator; the wind power generator system also comprises a separating apparatus used for performing multi-phase flow separation for flows from a windward direction; the air inlet of the separating apparatus is used for introducing flows from the windward direction; the air outlet is communicated with the motor cavity; and the motor cavity is communicated with an exhaust fan for discharging hot air flows. The invention also provides a fluid transportation apparatus, wherein the fluid transportation apparatus comprises power equipment with an overheat cavity; the fluid transportation apparatus also comprises the separating apparatus used for performing multi-phase flow separation for flows from the windward direction; the air inlet of the separating apparatus is used for introducing flows from the windward direction; the air outlet is communicated with the overheat cavity; and the overheat cavity is also communicated with the exhaust fan for discharging hot air flows.

Description

technical field [0001] The invention relates to the field of air cooling technology, in particular to a wind power generator system and a fluid transport device. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, mainly including components such as generators and blades. In the prior art, a permanent magnet synchronous motor is usually used as a wind power generator. Since the wind power generator is used outdoors and the natural environment is harsh, the temperature resistance of the permanent magnet of the generator is not high, and the cooling problem is particularly prominent. In order to achieve cooling of the generator while saving costs, air cooling is generally used in the prior art, that is, air in the natural environment is introduced into the air gap between the stator and the rotor of the generator for heat exchange to achieve cooling. [0003] However, the air in the natural environment is often mixed with...
