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.
