WIND POWER GENERATOR

摘要

A wind power generator provided with a wind turbine rotating in a wind tunnel body, capable of generating high output power by efficiently accelerating a wind flow. The wind power generator comprises a cylindrical wind tunnel body (1) expanding toward a flowing direction of wind and a wind turbine (3) for generating electricity arranged adjacent to an inlet (2a) for wind of the wind tunnel body (1), wherein an angle of inclination phi of a side wall portion of the wind tunnel body (1) relative to an axis of the wind tunnel body (1) is in a range from 5 to 25 degrees, the inlet (2a) of the wind tunnel body (1) has a curved surface (5) expanding smoothly toward an outside of the wind tunnel body (1), and a collar-shaped brim having a width B is formed on an outside of an opening edge of an outlet (2b) for wind of the wind tunnel body (1). Wind flowing in from the inlet (2a) for wind of the wind tunnel body (1) sharply accelerates immediately after passing through the inlet (2a) and efficiently rotates the wind turbine (3) arranged adjacent to the inlet (2a), thereby generate high output power. <IMAGE>
