Abstract:
A method for cooling an integrated circuit chip, comprising the steps of:providing an integrated circuit chip;providing a block of a thermally conductive material having at one end thereof a planar surface;securing said chip to said planar surface in such manner as to allow heat transfer between said chip and said block;providing at least one electrical circuit connection extending along said planar surface between an edge region of said block and said chip;providing a circuit board having an aperture for receiving at least a part of said block therethrough;providing at least one electrical circuit connection on a first side of said circuit board and extending to a connecting region adjacent said aperture;mounting said block to said circuit board with at least part of said block extending through said aperture, with said planar surface on a first side of said board, and with each of said at least one connection at said edge region of said block in contact with a respective one of said at least one connection at said connecting region of said board;providing a seal between said block and said board;providing a supply of flowing coolant; andpartially immersing said block in said flowing coolant so that said planar surface and said chip remain out of contact with said flowing coolant.
