PROBLEM TO BE SOLVED: To improve heat radiation within a tower top of a wind force power generation device and make a small-sized tower top.SOLUTION: This invention relates to a wind force power generation device 1 comprising a tower top 3 arranged at the upper end part of a tower 2 and a power generator 4 arranged at a side end part of the tower top 3. A power conversion unit panel 6 (heat generation part) and a cooling device 7 are stored in the tower top 3. The cooling device 7 comprises cooling liquid circulation passages 8, 9 for circulating cooling liquid to the power conversion panel 6; a radiator 10 for cooling the cooling liquid; and a cooling fan 11. The rotating shaft of the power generator 4 is provided with a rotational power transmission shaft 5, and the end part of the rotational power transmission shaft 5 opposing against the radiator 10 is provided with the cooling fan 11. The rotational power transmission shaft 5 is rotated in response to a power generating action of the power generator 4 so as to drive the cooling fan 11. |
