Abstract
An electric rotating machine includes a machine housing having a mixed condensation chamber, a rotor accommodated in the machine housing, and a stator accommodated in the machine housing in adjacent relationship to the mixed condensation chamber. A cooling device includes a first assembly to expose at least a part of the stator and/or the rotor to a vaporization coolant which vaporizes when contacting the part so as to effect a vaporization cooling, and a second assembly to dispense a liquid condensation coolant into the mixed condensation chamber for contacting the vaporization coolant so as to effect a mixed condensation of the vaporized vaporization coolant with the liquid condensation coolant in the mixed condensation chamber.
