Claims

[Scope of utility model registration request]

A cooling device for a rotating electrical machine comprising a blower provided outside a rotating electrical machine main body to be ventilated cooled, and a wind guide device equipped with a cylindrical guide tube that guides cooling air from the blower toward the rotating electrical machine main body. On the outer surface of the guide tube of the guide device, there are guide vanes that guide the cooling air from the blower in one direction, and a spiral guide plate that makes the cooling air swirl along the guide tube and generates a wind velocity of an axial component force. A cooling device for a rotating electric machine, characterized in that it is configured by providing the following.
