Abstract
A turbocharger includes a bearing housing containing a motor within an interior portion of the bearing housing. A liquid-cooled power module is secured to an exterior portion of a bearing housing. The power module contains electrical components that power and control speed of the motor, and has an enclosure that includes sealed first and second volumes separated by a common wall. The first volume is a liquid-cooled compartment for removing heat generated from the electrical components, and the second volume is a liquid-free compartment containing the electrical power components. The electrical power components are fixed to the common wall, which is formed of a heat conductive material, and which may include fins extending into the first volume to optimize heat transfer from the common wall into the liquid-cooled compartment. Finally, the liquid-cooled power module communicates with the motor directly through the bearing housing.
