Abstract
A wet cavity electric machine includes a stator core having stator poles formed by a post and a wire wound about the post to form a stator winding, with the stator winding having end turns, a rotor having two rotor poles and configured to rotate relative to the stator and a channel for liquid coolant to flow through the rotor to at least one nozzle, and liquid coolant sprays from the at least one nozzle at least a portion of the stator windings.
Claims20
A method of assembling a stator core, comprising:
- closing one end of at least one oscillating heat pipe;
- filling the at least one oscillating heat pipe with a working fluid in alternating phases to a predetermined ratio of fluid volume to total volume;
- closing another end of the at least one oscillating heat pipe;
- inserting the filled at least one oscillating heat pipe into a stator core;
- and
- wiring a set of windings into the stator core in a two-pole configuration wherein the set of windings surrounds only an evaporator portion of the at least one oscillating heat pipe, leaving a condenser portion exposed to a nozzle in a rotor.

A method of operating a power generation system, comprising:
- rotating a rotor having at least one nozzle relative to a stator core wound with a set of stator windings having at least one oscillating heat pipe received within the set of stator windings, the at least one oscillating heat pipe having an evaporator portion extending through the stator core and a condenser portion extending axially past the stator core proximate to the at least one nozzle, and wherein the evaporator portion and the condenser portion are positioned between sealed opposing ends of the at least one oscillating heat pipe;
- and
- thermally exposing the condenser portion of the at least one oscillating heat pipe to a liquid coolant passing through the at least one nozzle;
- wherein the exposure of the condenser portion to the liquid coolant will extract enough heat from the power generation system to enable the power generation system to operate within a set of predetermined parameters free of a cooling system external to the power generation system.
