Abstract:
1. A bottom fixation type integrated circuit chip cooling structure comprising: a top plate member, said top plate member having an edge lip that bounds a top surface and a bottom surface; a bottom plate member, said bottom plate member having an edge lip that bounds a top surface and a bottom surface, 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 bottom plate member has at least one through hole; at least one internally threaded connecting member provided between said top plate member and said bottom plate member corresponding to said at least one through hole, said at least one internally threaded connecting member having a bottom end inserted downwardly through one of said at least one through hole and peripherally sealed to the periphery of the corresponding through hole for mounting; said at least one internally threaded connecting member each has a top end thereof bonded to the bottom surface of said top plate member, so that said internally threaded connecting member extends through the bottom plate member; the bottom end of said at least one connecting member is configured to attach to a circuit board; a heat sink bonded to the top surface of said top plate member; and an internally sintered metal capillary wick provided within said vapor chamber.
