  • Operating a wind turbine generator cooling system
    Patent number: 11146143
    Abstract: Provided is a method for removing moisture from a cooling air filter installed for filtering first cooling air for cooling a generator from a first end, the method including: pressurizing second cooling air cooling the generator from a second end; allowing the second cooling air having received heat from the generator to pass through the cooling air filter, in order to absorb and thereby reduce moisture from the cooling air filter.
    Type: Grant

  • Cooling arrangement for a wind turbine
    Patent number: 11009011
    Abstract: A nacelle for a wind turbine extends along a longitudinal axis between a front side where a wind rotor is rotatably attachable to the nacelle for rotating about the longitudinal axis and a longitudinally opposite rear side is provided. The nacelle includes an outer surface delimiting an inner volume of the nacelle, a cooling path for circulating a cooling flow in the inner volume. The nacelle further includes a pressure source for generating an overpressure inside the inner volume of the nacelle, the pressure source including an inlet at the outer surface for receiving the cooling flow and an outlet for delivering the cooling flow in the inner volume, at least one heat exchanger provided in the outer surface for receiving the cooling flow from the inner volume.
