Abstract:
1. A low-pressure drop thermal assembly for thermal management of a semiconductor device comprising: a subassembly comprising a manifold directly attached to a distributor, said manifold having a fluid inlet opening integral with a fluid inlet pipe and isolated from a fluid outlet opening that is integral with a fluid outlet pipe, said distributor having a fluid inlet body intertwined with a fluid outlet body, said fluid inlet body having a fluid inlet microjet array intertwined with and isolated from a fluid outlet microjet array whereby each inlet microjet is adjacent at least three outlet microjets, said manifold being attached to said distributor such that said fluid inlet opening of said manifold communicates with said fluid inlet microjet array of said distributor and said fluid outlet opening of said manifold communicates with said fluid outlet microjet array of said distributor; a substrate surface in communication with said subassembly; a semiconductor device on said substrate surface, said semiconductor device having a first surface orthogonal to an input, output direction flow of a fluid input by said microjet input array and output by said distributed microjet outlet array, and having a second surface with hierarchy thereon connected to said substrate surface; a cavity residing between said subassembly and said substrate surface; a seal of said cavity around said semiconductor device for protecting said hierarchy from said fluid; and a total internal liquid pressure drop below about 10 psig through use of said distributor.
