Patent ID: 7042723

Claim:
A cooling arrangement for an integrated circuit which is mounted in a socket on a printed circuit board, comprising, an insulating housing positioned around the integrated circuit and defining an edge near the printed circuit board, said insulating housing including an inlet stub for coolant, an outlet stub for coolant, and a supply pipe for supplying coolant to said inlet stub, a lid positioned against the insulated housing and on said printed circuit so as to define an evaporation cavity within the housing, said lid including a plurality of cooling rods so that coolant flowing through said evaporator cavity will cool said lid and thus said printed circuit board, a sealing material which is impermeable to the transport of fluids circumferentially positioned between the housing and the printed circuit board to prevent air flow therethrough and moisture formation on the printed circuit board, said sealing material being an ethylene-propylene-diene copolymer, and a bottom flange having a bottom fixed below the printed circuit board, and said sealing material is located between the bottom flange and the printed circuit board.
