転電機の冷却装置。[Claims for Utility Model Registration] (1) A frame made of a cylindrical metal material, with a stator core fixed to the inner circumference, and a frame with both open ends closed and a plurality of radially arranged a bracket provided with a wind window; a rotating shaft rotatably supported via a bearing fixed to the bracket;
It consists of a fan that is fixed to a rotating shaft and rotates by the rotational force of this rotating shaft, and a ring-shaped flat plate.
A part of this flat plate material is fixed to the above bracket,
and a fan guide provided such that the ring-shaped inner diameter portion of the flat plate material is located near the fan, and a wind window portion is provided on the flat plate surface near the outer periphery of the fan guide. The rotation is characterized in that the outside air is sucked into the bracket through the wind window on the inner diameter side of the bracket, and is exhausted again from the wind window on the outer peripheral side of the bracket via the wind window on the fan guide. Electrical cooling equipment. (2) Claim No. 1 for Utility Model Registration, characterized in that the wind window of the fan guide has a wind window area that is approximately the same as the area of the exhaust wind window provided on the outer peripheral side of the bracket. A cooling device for a rotating electric machine as described in . (3) The cooling device for a rotating electric machine as set forth in claim 1 or 2 of the utility model registration claim, wherein wind windows are provided in the vicinity of both openings of the frame in the direction of the outer periphery.
