Abstract
A power-module assembly includes a plurality of power modules each including a power stage having a substrate and a transistor-based switching arrangement supported on the substrate. The power modules are arranged in a stack that defines coolant chambers interleaved with the power stages and defines a pair of coolant-supply manifolds disposed on opposing sides of the stack and extending along a length of the stack. For each power module, the substrate defines a network of cooling channels connecting the supply manifolds to a corresponding one of the chambers. The network includes first channels each configured to receive coolant from the pair of coolant-supply manifolds, second channels substantially parallel to the first channels and each opening into the corresponding one of the chambers, and third channels crisscrossing the first and second channels to connect the first and second channels in fluid communication.
