Abstract:
1. A cooling apparatus for a power electronics system comprising: a jet plate comprising a support plate and an array of jet bodies extending from a surface of the support plate in a first direction, wherein each jet body of the array of jet bodies comprises an impingement jet channel disposed within the jet body, and each jet body is spaced apart from adjacent jet bodies, thereby forming a plurality of fluid collection passageways arranged in a grid pattern; a target plate comprising an array of microchannel cells, each microchannel cell comprising a plurality of wavy-fin microchannels radially extending from an impingement location positioned opposite from an individual impingement jet channel, wherein each impingement location is positioned to receive an impingement jet of coolant fluid introduced into the cooling apparatus; and a fluid outlet that is fluidly coupled to the fluid collection passageways, wherein the plurality of fluid collection passageways and the fluid outlet are arranged such that coolant fluid introduced into the cooling apparatus flows through the plurality of fluid collection passageways toward the fluid outlet in a direction that is orthogonal to the first direction.
