Abstract

An impingement cooling system includes a porous heat spreader and a nozzle configured to direct a fluid as a jet and/or as a spray impinging upon the porous heat spreader. The porous heat spreader is made of a thermally-conductive material such as a metal, metal alloy, carbon/graphite, or ceramic, and is in thermal contact with a heat source. The nozzle may be configured to direct the fluid as a jet comprising a single component liquid or gas (including air) or a liquid mixture such as water-glycol or other coolants. The nozzle may be configured to direct the fluid as a spray comprising a single component liquid or gas (including air) or a liquid mixture such as water-glycol or other coolants. The cooling system may include one or more nozzles, which may direct the cooling fluid orthogonally or at an oblique angle to an impingement plate.
