Cooling device for a wind turbine generator

摘要

A wind turbine generator (1) is provided with: a nacelle (3); a device placed in the nacelle; and a cooling duct (18) comprising a duct inlet (22) and a duct outlet (23) which are provided in a wall surface of the nacelle (3), the cooling duct forming a duct interior space between the duct inlet (22) and the duct outlet (23) independently of an interior space of the nacelle (3). The cooling duct is configured to lead ambient air introduced directly from the duct inlet (22) without a filter to a cooling object part (21) of the device disposed in the duct interior space. The duct inlet (22) is disposed at a lower position than the cooling object part (21).
