  • Turbogenerator cooling method
    Patent number: 6720685
    Abstract: A turbogenerator cooling system is disclosed that has a cylindrical heat sink with generally axially extending fins on both the outside and inside of a hoop section. The hoop section is solid except for holes adjacent to the rear end thereof. The generator stator is press-fitted into the heat sink in contact with the internal fins. The generator rotor is fitted with a small fan for directing heated air away from the inlet of the engine. Cooling air passes along the external fins to the rear of the generator, flows through the holes in the hoop section passes forward between the inside of the hoop section and the external surface of the stator to cool the stator and along an alternate path to cool the rotor hollow sleeve and permanent magnetic shafts as well as the stator.
