Abstract

The invention relates to the technical field of wind power generator cooling equipment, in particular to a cooling device for a wind power generating unit and the wind power generating unit. The cooling device for the wind power generating unit is provided and comprises an outer radiator, a drive mechanism and at least one heat exchange element, the heat exchange element and the outer radiator arein communication through a pipeline to form a cooling loop, the cooling loop is internally provided with liquid metal, and the drive mechanism drives the liquid metal to circularly move in the cooling loop. According to the cooling device for the wind power generating unit and the wind power generating unit, the liquid metal is introduced for the first time to serve as a cooling medium of the wind power generating unit, and due to the fact that the liquid metal combines high heat conductivity of the metal medium and fluidity of fluid, efficient heat transportation and extreme heat dissipationcapability is achieved, and the cooling efficiency is improved. Meanwhile, the liquid metal is stable in physical and chemical property and easy to recycle, and safe and efficient running of the cooling device can be guaranteed. In addition, the provided cooling device is simple in structure, low in manufacturing cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of cooling equipment for wind power generators, in particular to a cooling device for wind power generators and a wind power generator, in particular to a cooling device for wind power generators with high cooling efficiency, stable and reliable operation, and easy recycling. devices and wind turbines. Background technique [0002] The main heat-generating components of wind turbines are gearboxes, generators and control frequency converters. Most of the faults that occur during the operation of the fan are due to the excessive temperature of the gearbox oil, the overload of the oil pump, and the excessive temperature rise of the generator winding caused by heat accumulation. Therefore, in order to ensure long-term stable, high-efficiency and stable operation of the generator set, it is necessary to effectively cool the above components. The early wind turbines had low power, so they did not generate much ...
