Patent ID: 7905106

Claim:
A liquid submersion-cooled server computer array, comprising: a plurality of server computer cases arranged in an array, each case including: a plurality of walls including a lid defining a liquid-tight interior space; a server logic board disposed in the interior space; a plurality of heat generating computer components disposed on the server logic board; a plenum housing within the interior space; the plenum housing includes an inside space, a cooling liquid inlet port in communication with the inside space, and a cooling liquid exit opening in communication with the inside space, and the plenum housing is disposed over one of the heat generating computer components disposed on the server logic board, wherein the plenum housing contains a flow of cooling liquid that is introduced through the cooling liquid inlet port as the cooling liquid flows over the one heat generating computer component toward the cooling liquid exit opening to increase the cooling effectiveness on the one heat generating computer component; a dielectric cooling liquid disposed within the interior space and submerging the plurality of heat generating computer components disposed on the server logic board; a liquid inlet in one of the walls enabling dielectric cooling liquid to enter the case; a liquid outlet in one of the walls enabling dielectric cooling liquid to exit the case; a manifold within the interior space and fluidly connected to the liquid inlet; a tube within the interior space fluidly connected to the manifold and to the cooling liquid inlet port of the plenum housing to direct flow of the dielectric cooling liquid from the manifold into the plenum housing; and a liquid and gas-tight sealed electrical connector extending through one of the walls and electrically connected to the computer components on the server logic board; and a rack system, the plurality of server computer cases of the array are arranged on the rack system.
