Cooling apparatus, cooled electronic module and methods of fabrication thereof employing an integrated manifold and a plurality of thermally conductive fins

摘要

A cooling apparatus and method of fabrication are provided for facilitating removal of heat from a heat generating electronic device. The cooling apparatus includes a plurality of thermally conductive fins coupled to and projecting away from a surface to be cooled. The fins facilitate transfer of heat from the surface to be cooled. The apparatus further includes an integrated manifold having a plurality of inlet orifices for injecting coolant onto the surface to be cooled, and a plurality of outlet openings for exhausting coolant after impinging on the surface to be cooled. The inlet orifices and the outlet openings are interspersed in a common surface of the integrated manifold. Further, the integrated manifold and the surface to be cooled are disposed with the common surface of the manifold and the surface to be cooled in spaced, opposing relation, and with the plurality of thermally conductive fins disposed therebetween.
