Claims13
A wind power installation, comprising:
- a nacelle rotatably mounted for positioning in a wind direction;
- a generator disposed in the nacelle and including a closed primary cooling system;
- a turbine connected to the nacelle and having at least one rotor blade rotated by wind power for driving the generator to produce electric energy, and
- a secondary cooling system connected to the nacelle so as to align in wind direction as the nacelle rotates and being passed by circulating heated air generated by the primary cooling system during cooling of the generator for cooling the heated air from the primary cooling system.
