Provided is a wind turbine generator in which the intake air temperature of an air-cooled heat exchanger disposed in a nacelle is decreased to allow efficient heat exchange. A wind turbine generator that generates electric power in such a manner that a rotor head that rotates when receiving wind power drives a generator installed inside a nacelle, the nacelle being installed at the upper end of a tower that is vertically erected on a foundation, and the wind turbine generator including a closed-circuit lubricating-oil circulation system in which lubricating oil circulates through devices installed inside the nacelle, wherein an air-cooled heat exchanger installed in the lubricating-oil circulation system to cool the lubricating oil by heat exchange with air is provided in a region separate from nacelle air.

Wind turbine generator including air-cooled heat exchanger

A wind power generating apparatus provided with heat exhausting measures for an in-rotor-head device is provided. In a wind power generating apparatus in which a rotor head that rotates upon receiving wind power on a wind turbine blade drives a generator that is installed inside a nacelle and thereby generates electric power, the nacelle is installed on an upper end portion of a tower that is erected on a foundation, and a hub control panel is installed inside the rotor head, a ventilating fan that forms a flow inside and outside of an enclosure of the hub control panel is provided in the enclosure.
