<P>PROBLEM TO BE SOLVED: To provide a wind power generator that generates power by making the most of exhaust energy from a duct. <P>SOLUTION: In the wind power generator, a tip part of a duct is formed of a duct body 11 and cylindrical bodies 12, 13 inserted with gaps g1, g2 formed in the tip of the duct body 11, and a wind turbine is provided in the downstream of the cylindrical bodies 12, 13. The cylindrical bodies 12, 13 have an axial cross section in the shape of an aerofoil. Front outer circumferential surfaces 24, 34 continued from a front rim are formed to gradually increase an outer diameter toward the rear. On a rear outer circumferential surface, circular arc surfaces 25, 35 are formed for gradually guiding the air flowing out radially outside along the front outer circumferential surfaces 24, 35 from the gaps g1, g2, radially inward. <P>COPYRIGHT: (C)2013,JPO&INPIT |
