Patent Images
1. A power electronics module comprising:
- a housing forming a cold plate;
a heat generating electronic first component;
a heat generating electronic second component having a bus-bar connected to the first component, the second component having a housing forming a side which faces the cold plate, the bus-bar exiting from a central portion of said side of the second component and being positioned adjacent to the cold plate, the bus-bar forming a flat plate which extends from said central portion to and past an edge of said side; and
the cold plate forming a cooling passage which underlies the first component and the bus-bar.

Abstract
A power electronics inverter includes a housing which forms a cold plate with coolant passages. The housing encloses an insulated gate bipolar transistor (IGBT), and a DC Link capacitor. The capacitor comprises a bus-bar which exits from a bottom side of the capacitor, and the bus-bar is positioned adjacent to the cold plate. The cold plate forms a cooling passage which underlies the IGBT and the capacitor bus-bar. Thermally conductive gap pads are located between the capacitor bus-bar and the cold plate.
