WIND TURBINE GENERATOR, WIND TURBINE GENERATING METHOD AND WIND TUNNEL MEMBER USED FOR WIND TURBINE GENERATOR

摘要

PROBLEM TO BE SOLVED: To improve a rotary force of a wind force fan, amplifying a wind force by minimizing the wind resistance in the wind tunnel. SOLUTION: Wind intakes 7 for taking in the wind are formed in a side wall 4a of the wind tunnel 4 by communicating the inside and the outside of the wind tunnel. The wind intakes 7 are set at four positions with an interval of approximately 90 degrees about a center shaft in the longitudinal direction of the wind tunnel 4 so that the wind can be taken in from the periphery of the side face 4a of the wind tunnel 4 regardless of a wind direction. The wind intakes 7 are provided with a hood 7a for expanding a diameter from the side face 4a of the wind tunnel 4. In the hood 7a, an opening 7b for communicating to an opening 4b of the wind tunnel 4 formed at the side face 4a of the wind tunnel 4 opened downward is formed. COPYRIGHT: (C)2004,JPO&NCIPI
