TWO-PHASE ELECTRIC MOTOR COOLER

摘要

An electric motor system includes a motor housing and a stator core disposed within the motor housing. The stator core includes a back iron heat exchanger for passing fluid therethrough. A fluid inlet is disposed at a first portion of the back iron heat exchanger that is at least partially in fluid communication with a liquid coolant source and is configured to accept a cooling mixture. A fluid outlet is disposed at a second portion of the back iron heat exchanger for outletting a gas coolant from the back iron heat exchanger such that liquid coolant is convertible to the gas coolant in the back iron heat exchanger by receiving energy from the stator core allowing the gas coolant exit through the outlet and thereby removing heat from the stator core.
