Abstract

A heatsink or cold plate is provided with which power electronic components mounted to a surface of the cold plate can be cooled with a cooling fluid flowing through the cold plate. The cold plate generally consists of a relatively planar structure through which one or more passages are formed for directing the cooling fluid through the cold plate. The passages direct the cooling fluid to recesses in the surface of the cold plate which are enclosed by the power electronic components. As such, cooling of the power electronic components is achieved by directly impinging the cooling fluid at their lower surfaces, preferably at an acute angle, such that enhanced heat transfer characteristics result.
