Problems solved by technology

These losses cause the motor to release a lot of heat during operation, and this heat will not only cause a certain impact on the motor itself and its insulation structure, resulting in shortened insulation life or even insulation failure, but also lead to a continuous decline in the output power of the motor

Abstract

The invention relates to an air cooling system, a wind power generation unit and a cooling method thereof. The air cooling system is arranged between a cabin of the wind power generation unit and an air inlet of a power generator and comprises more than two subsystems which independently run; each subsystem comprises a dehumidifying device and drive equipment; each dehumidification device is arranged on the wall part of the cabin and communicates with the cabin; and each drive equipment is arranged in the cabin, so that external cooling air is introduced into the cabin through the corresponding dehumidification device to be mixed with a part of high-temperature air discharged from an air outlet of the power generator and performs heat exchange with a heating component of the cabin and / or the power generator, wherein the drive equipment of the more than two subsystems runs at the same time to realize a first function and alternately runs for a predetermined time to realize a second function. The air cooling system extends the functionality of the air cooling system.

Description

technical field [0001] The invention relates to the technical field of cooling, in particular to an air cooling system, a wind power generating set and a cooling method thereof. Background technique [0002] Wind power is one of the renewable energy technologies closest to commercialization and is the focus of renewable energy development. The motor in the wind turbine has heat loss during operation, which mainly includes: electromagnetic loss, that is, Joule heat generated by ohmic impedance in the winding, that is, copper loss; hysteresis loss and eddy current loss in the iron core, that is, iron loss. loss; and unavoidable stray loss; if it is a permanent magnet motor, it also includes magnet loss. These losses cause the motor to release a lot of heat during operation, and this heat will not only cause a certain impact on the motor itself and its insulation structure, resulting in shortened insulation life or even insulation failure, but also lead to a continuous decline...
