The present invention improves the construction of a cooling ventilation flue for the coil end portion of the stator of a rotary electric machine so as to enhance the cooling effect. That is, the invention provides a cooling device for a rotary electric machine characterized by comprising a ventilation guide which is disposed at the coil end portion of the stator of the rotary electric machine, which divides the stator coil end portion in an axial direction of the rotor of the rotary electric machine into a first ventilating section for advancing cooling air onto an inner peripheral side of the coil end portion and a second ventilating section for advancing the cooling air, having passed through the first ventilating section, onto an outer peripheral side of the coil end portion and which guides the cooling air, having passed through the second ventilating section, into a space surrounding the stator. |
