Power-Module Assembly

摘要

A method of forming a power-module assembly includes arranging power stages in a cavity of a container such that the power stages are spaced apart from walls of the container. The method further includes inserting a core between each of the power stages, and installing a manifold on top of the power stages. The method also includes putting resin into the cavity to form a housing of the power-module assembly, and removing the core to reveal coolant chambers between each of the power stages.

主权项

1. A method of forming a power-module assembly for an automotive power inverter comprising:
arranging a plurality of power stages in a mold cavity of a container such that the power stages are in a linear array with spacing between each of the power stages, and such that the power stages are spaced apart from walls of the container; inserting a core into the cavity such that fingers of the core are disposed in the spacing between the power stages; inserting a manifold into the cavity such that the manifold is disposed on a top of each of the power stages; pouring resin into the cavity to form at least a portion of a housing of the power-module assembly; and removing the core to reveal a plurality of chambers between each of the power stages.
