Abstract:
1. A power electronics assembly comprising: a housing defining at least one cavity and having a fluid passageway extending through the cavity, the fluid passageway having first and second portions extending through respective first and second opposing sides of the at least one cavity, wherein the housing comprises first and second side walls each comprising inner surfaces and outer surfaces, the inner surfaces having a recessed formed thereon, the first and second portions of the fluid passageway being formed within the respective first and second side walls; and a plurality of inductors housed within the at least one cavity of the housing such that the first and second portions of the fluid passageway are on first and second opposing sides of each of the plurality of inductors, wherein the fluid passageway also extends around the plurality of inductors within the cavity, wherein each of the plurality of inductors comprises a conductive winding arranged such that when current flows through the conductive winding, heat generated therein is conducted from the first side of the respective inductor to the first portion of the fluid passageway and from the second side of the respective inductor to the second portion of the fluid passageway, wherein each of the plurality of inductors comprises a ferromagnetic core and the conductive winding of each of the plurality of inductors is wrapped around the respective ferromagnetic core, and wherein the conductive winding of each of the plurality of inductors is at least partially located within the recesses on the inner surfaces of the first and second side walls.
