<P>PROBLEM TO BE SOLVED: To provide a wind-driven electric power generator which can be adapted to a wide variety of installation environments, independent of outdoor air temperatures and in which the inside of a nacelle can be ventilated and cooled. <P>SOLUTION: In the wind-driven electric power generator, devices E including a drive-electric power generation mechanism are connected to a rotor head 4 on which a windmill blade is mounted, the devices E are received and installed in the nacelle 3, a ventilation fan installed in the nacelle 3 is driven to introduce outside air from a suction opening 31 installed in the front face of the nacelle, the introduced outside air is discharged to the outside of the nacelle 3 from a discharge opening 32 connected to a fan exit, and thereby the inside of the nacelle 3 is ventilated and cooled. A side suction opening 34 is additionally provided in that portion of a nacelle side face 3a at which negative pressure is produced by air flow flowing the outside of the nacelle. <P>COPYRIGHT: (C)2010,JPO&INPIT |
