A heat exchanger apparatus is provided and includes a motor controller housing, supportively disposed with a turbofan within an aircraft engine nacelle, in which motor controller components are mounted, a fuel cooled cold plate, forming a surface of the housing, which forms a heat transfer path by which motor controller component generated heat is dissipated during first conditions and an air cooled cold plate, disposed in thermal communication with the fuel cooled cold plate, which extends into a flow path of nacelle air generated by the turbofan to form an extended heat transfer path by which the motor controller component generated heat is dissipated during second conditions.
