摘要： Cooling systems and methods are provided for an integrated electric motor-inverter, where the integrated electric motor-inverter includes a housing, a motor, and an inverter, the motor and the inverter are disposed within the housing, and the motor includes a stator. The system includes a cooling jacket, a first coolant, a condenser, a spray head, and a second coolant. The cooling jacket is disposed concentric to the stator and includes an inner wall and an outer wall. The inner wall is in direct contact with the stator. The first coolant is disposed between the cooling jacket inner and outer walls. The condenser is disposed concentric to the cooling jacket. The spray head is disposed adjacent the inverter. The second coolant is in flow communication with the spray head.
