Abstract
The present invention provides a wind generator which effectively utilizes an opening of a door opening and a shell plate, and in which an outside air-circulation flow path for introducing outside air into a cooling heat exchanger in a tower is formed. In the wind generator, a cooling medium that cools a heating element disposed in the tower circulates through a cooling heat exchanger, and heat is absorbed by exchanging heat with outside air, an outside air-circulation flow path of a closed space having an outside-air inflow opening and an outside-air discharge opening that are in communication with a door opening of a shell plate is formed in an interior space in the tower, and the cooling heat exchanger is disposed in the outside air-circulation flow path.
Claims5
A wind generator in which a rotor head has windmill blades, the rotor head rotates when the windmill blades receive wind power and drives a power generator disposed in a nacelle to generate electricity, the nacelle is disposed on an upper end of a monopole tower that stands on a base, a cooling medium that cools a heating element disposed in the tower circulates through a cooling heat exchanger, and heat is absorbed by exchanging heat with outside air, wherein
- an outside air-circulation flow path of a closed space having an outside-air inflow opening and an outside-air discharge opening that are in communication with an opening of a shell plate is formed in an interior space in the tower, and the cooling heat exchanger is disposed in the outside air-circulation flow path.
The wind generator according to 1, further comprising a partition wall provided around the opening of the shell plate in the tower and the shell plate, wherein the outside air-circulation flow path is constructed of the partition wall and the shell plate.
