Wind power generator cooling system

The utility model provides a novel wind power generator cooling system. The novel wind power generator cooling system includes a wind cooling system used for cooling a wind power generator in an operation process, a cool capacity storage and release system used for storing and releasing cool capacity, a cooling system used for providing cool capacity for the cool capacity storage and release system and a heat-extraction system used for discharging heat energy produced by the cooling system. The heat-extraction system is connected with the cooling system. The wind cooling system is connected with the wind power generator. The cool capacity storage and release system is connected with the wind cooling system and the cooling system respectively. The novel wind power generator cooling system provided by the utility model can produce and store cool capacity in off-peak electricity time periods with comparatively low power grid load and can release stored cool capacity to the wind power generator for cooling in a c
