摘要：A new system for removing heat energy from the rotor of a rotating electricalmachine is disclosed. Rotating electrical machines include electric motors, electricgenerators and the like. The cooling system includes the prior art components of anintegral heat pipe rotor shaft, that is, a hollow rotor shaft in which an inner cavity is filledwith a suitable working fluid to make an integral heat pipe for removing heat from therotor. The heat pipe includes an evaporator section inside the rotor and a condensersection extending outside the rotor and the electrical machine housing. The presentinvention adds a spray chamber surrounding the condenser section. The spray chamber isintegrated with the electrical machine housing. Liquid coolant enters the spray chamberand is sprayed through nozzles onto the condenser section to remove the heattransferred from the rotor. The liquid coolant may be routed through a preheaterbefore entering the spray chamber.
