Abstract

See full text

A hybrid cooling system of an electric machine is contemplated. The hybrid cooling system comprises a propeller positioned on an exterior of an enclosure, at least one electronic component disposed within the enclosure, and a vapor chamber disposed within the enclosure, wherein the vapor chamber comprises an actuator configured to generate mist from a liquid coolant within the enclosure. In operation, in a first mode, the propeller rotates for generating air that is channeled into the enclosure via fins that are disposed on exterior portions of the enclosure, and in a second mode, the actuator generates mist within the vapor chamber, and the propeller rotates for generating air that is channeled into the enclosure via the fins disposed therein.
