Claims25
A hub cooling apparatus adapted for a wind-power generator, comprising:
- a circulating fan module installed in a nosed end of a hub;
- and
- a wind guiding module installed in a main shaft of a nacelle;
- wherein the circulating fan module is driven by the rotating hub, the wind guiding module is driven by the rotating main shaft.
1 more element
A hub cooling method, adapted to a wind power generator, comprising the steps of:
- enabling a circulating fan module to be driven to operate by a rotating hub while allowing air in the hub to be driven to flow and circulate by the operation of the circulating fan module;
- and
- activating a first fan and a second fan that are both arranged inside a nacelle for drawing hot air inside the hub to flow into the nacelle while forcing cold air inside the nacelle to be flow into the hub.
