Abstract:
1. A thermal management system for an electronic device being liquid spray cooled by thin film evaporative spray cooling, the thermal management system comprising: a recipient base comprising: a front surface comprised of a plurality of radially inward raised impingement surfaces and a plurality of radially outward raised impingement surfaces, with each of the raised impingement surfaces being oriented to directly receive droplets of atomized cooling fluid from a common atomizer which sprays the liquid the cooling fluid at an approximate angle of ninety degrees wherein the plurality of radially inward raised impingement surfaces being at an angle to the recipient base less than the plurality of radially outward raised impingement surfaces to manage heat transfer; a plurality of drainage passages among the plurality of raised impingement surfaces, each disposed to receive a flow of cooling fluid flow of the cooling fluid from the plurality of raised impingement surfaces and further disposed to facilitate the flow of the cooling fluid generally away from the common atomizer; and further wherein the plurality of raised impingement surfaces are configured to normalize an impact angle of liquid coolant on the substantial area of the plurality of raised impingement surfaces.
