Abstract:
An integrated circuit chip cooling structure comprising:a top plate member, said top pate member having an edge lip that bounds a top surface and a bottom surface of the top plate member; a bottom plate member, said bottom plate member having an edge lip that bounds a top surface and a bottom surface of the bottom plate member, the edge lips of said top and bottom plate members being bonded together so as to define a vapor chamber between said top and bottom plate members; wherein said top plate member and said bottom plate member each have at least one through hole, the at least one through hole of said top plate member and the at least one through hole of said bottom plate member being respectively vertically aligned; at least one connecting member extending between said top plate member and said bottom plate member, said connecting member having a top end sealed to a periphery of the through hole of said top plate member and a bottom end sealed to a periphery of the through hole of said bottom plate member, said at least one connecting member having a through hole extending through the connecting member from the top end to the bottom end for receiving a fastener; at least one heat sink, said at least one heat sink having a bottom surface attached to the top surface of said top plate member and at least one mounting hole respectively connected to the through hole of said at least one connecting member, said fastener extending through said through holes of said top plate member, said bottom plate member, and said connecting member, and through said mounting hole of said at least one heat sink, to secure said heat sink to said top and bottom plate members; and an internally sintered metal capillary wick provided within said vapor chamber.
