ABSTRACT:
An integrated cooling system includes a housing and a pumping device disposed within the housing, configured to pressurize a fluid. The cooling system also includes a motor disposed within the housing and operatively coupled to the pumping device. The cooling system further includes a first cooling circuit configured to receive the pressurized fluid and circulate the pressurized fluid through at least one component external to the housing. The cooling system also includes a second cooling circuit in fluid communication with the first cooling circuit, and configured to direct at least a portion of the pressurized fluid through the motor.
