Abstract:
1. A cooling apparatus comprising: a fluid inlet channel; a jet orifice surface comprising one or more jet orifices fluidly coupled to the fluid inlet channel such that coolant fluid within the fluid inlet channel flows through the one or more jet orifices as one or more impingement jets; a target surface, wherein the target surface and the jet orifice surface define an impingement chamber, the one or more impingement jets impinge the target surface at an impingement region, and at least some of the coolant fluid changes to a vapor; and a plurality of sloped vapor outlet channels fluidly coupled to the impingement chamber, wherein each sloped vapor outlet channel slopes in a direction that is both away from the jet orifice surface and opposite from a direction of the one or more impingement jets, and the coolant fluid in the form of one or more of vapor flows and fluid flows through the plurality of sloped vapor outlet channels after impinging the target surface.
