GENERATORS WITH OPEN LOOP ACTIVE COOLING

摘要

A rotor body for a high-speed generator includes a rotor body with interior and exterior surfaces, a coolant inlet and outlet, and a rotor cooling path for actively cooling the rotor body. The coolant inlet and outlet extend between the interior and exterior surfaces. An interior segment of the rotor cooling path fluidly couples the coolant inlet and coolant outlet and is bounded by the rotor body interior surface. An exterior segment of the cooling path is bounded by the rotor body exterior surface and fluidly couples the coolant outlet an environment external to the rotor body.

1. A rotor for a high-speed generator, comprising:
a rotor body defining:
an interior surface and opposed exterior surface; anda coolant inlet and outlet extending between the interior and exterior surfaces; and a rotor cooling path including (i) an interior cooling path segment bounded by the rotor body interior surface and fluidly coupling the coolant inlet to the coolant outlet, and (ii) an exterior cooling path segment bounded by the rotor body exterior surface and fluidly coupling the coolant outlet to an external environment for open loop cooling the rotor body.
