Peristaltic Pump for Power Electronics Assembly

Abstract

A power electronics assembly may include a power electronics device, a packaging assembly, a thermal management system, and an emitter. The packaging assembly supports power electronics device. The thermal management system supports the packaging assembly and includes a thermal plate to deliver coolant for thermally communicating with the device. The thermal plate defines a channel with a wall. The emitter is arranged with the wall to form a peristaltic pump to adjust a cross-sectional area of the channel to control a flow of coolant therethrough. A membrane may be partially secured to the wall and include one of dielectric particles or magnetic particles. The emitter may selectively output one of a voltage, an electric field, or a magnetic field to impart a force on the particles to move the membrane and adjust the cross-sectional area of the channel to control a flow of coolant therethrough.
