Abstract
The invention provides a wind turbine generating apparatus capable of controlling a temperature in a rotor head. In a wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, an air circulation guide is provided for allowing air to circulate between an inside of the rotor head and an inside of the nacelle via a communication path formed between the rotor head and the nacelle.
Claims10
A wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, the apparatus comprising
- an air flow forming means for allowing air to circulate between an inside of the rotor head and an inside of the nacelle via a communication path formed between the rotor head and the nacelle.
A wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, the apparatus comprising:
- an outside air introducing path allowing an outside of the rotor head and an inside of the hub to communicate with each other and having a louver;
- and
- an outside air circulating path where outside air, which is introduced from an inlet of the outside air introducing path into the hub, passes through an outflow hole opened in the hub and a communication path formed between the rotor head and the nacelle, so as to flow to the outside.
A wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, the apparatus comprising
- a heat dissipating means provided to at least one of the rotor head and the hub.
