<P>PROBLEM TO BE SOLVED: To provide a wind power generation device capable of efficiently cooling apparatuses inside a nacelle by a fan cooler under the extensive condition of the outside air temperature. <P>SOLUTION: A fan cooler of a wind power generation device for cooling apparatuses arranged inside a nacelle 3 comprises an intake port 11 which is opened in a nacelle outer shell 10 to introduce the outside air into the nacelle, an outlet opening 12 which is formed in the nacelle outer shell 10 to exhaust air inside the nacelle, an exhaust port 14 which is formed at an outlet of a duct 13 to exhaust the air inside the nacelle to the atmosphere, and a ventilation fan 15 which is installed in a vicinity of the outlet opening 12 inside the nacelle to suck the outside air from the intake port 11, and exhaust the air inside the nacelle from the exhaust port 14. A bypass flow passage 16 for returning a part of the air to be exhausted from the exhaust port 14 is provided on the downstream side of the ventilation fan 15. <P>COPYRIGHT: (C)2010,JPO&INPIT |
