Abstract
A pump assembly and a method for cooling the same are disclosed. The pump assembly includes a pump, a controller, and a driven electric motor. The pump and the electric motor are on opposing axial sides of the controller. The assembly also has a heat conductive plate positioned between the pump and the controller that conducts heat from the controller. A transfer passage is provided for receiving pressurized fluid output from the pump and to direct the fluid along and in contact with the heat conductive plate to conduct heat therefrom into the pressurized fluid. An outlet passage communicates with the assembly outlet to discharge the pressurized fluid.
