Claims

[Scope of utility model registration request]

A heat exchange casing has a large number of heat exchange pipes arranged in a row, and outside air discharged by an outside air supply fan consisting of a centrifugal fan disposed in a fan chamber is directed through an outside air supply duct to change the direction of each of the heat exchange pipes. In this apparatus, the internal air of the rotating electrical machine is passed through and returned to the arrangement space of the heat exchange pipes to exchange heat, wherein the peripheral wall of the outside air supply duct near the heat exchange casing has an arcuate cross section or The peripheral wall of the heat exchange casing is formed into a polygonal shape, and the peripheral wall of the heat exchange casing is formed to have an arcuate or polygonal cross section that is approximately the same shape as the peripheral wall of the outside air supply duct, and on the outside of the peripheral wall of the heat exchange casing,
A cooling device for a rotating electric machine, characterized in that a road wall body is provided that forms an outside air introduction path for introducing outside air into the fan chamber.
