Abstract
Abstract A low temperature conduction module comprising a cold plate having recesses around the periphery thereof to accommodate memory cubes is disclosed. The recesses accommodating the memory cubes are of such depth and dimension as to enclose the memory cube on all but one side, thereby greatly enhancing the conduction of the heat generated by the memory cube to the cold plate. The memory cube may be surrounded by a material which possesses excellent thermal conductive properties to insure efficient transfer of the heat from the memory cube to the cold plate. The plurality of memory cubes so positioned within the cold plate may be connected by a flexible cable surrounding the cold plate and having branch conductors extending to connect with computer processors enclosed within the same low temperature conduction module.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
A cryogenically coolable thermal conduction module for containing and cooling electronic circuit chips having a plurality of faces, said module comprising: a container having at least a top wall, a bottom wall, and a side wall which define an internal volume; said bottom wall having a planar, thermally conductive plate exposed for engagement with a cryogenically cooled cold head; said bottom wall further having an internal cylindrical portion extending axially from the periphery of said bottom wall and having a thickness in the radial direction in excess of one dimension of at least one face of at least one electronic chip; and at least one recess formed into the exterior of said cylindrical portion which accepts at least one said chip into each said recess and which contacts at least a plurality of said faces of at least one said chip, whereby heat generated within said chip is conducted away from said at least one chip through any of a plurality of said faces, to said plate.
Claim 2
Dependent Claim
167 words
A cryogenically coolable thermal conduction module for containing and cooling electronic circuit chips having a plurality of faces, said module comprising: a container having at least a top wall, a bottom wall, and a side wall which define an internal volume; said bottom wall having a planar, thermally conductive plate exposed for engagement with a cryogenically cooled cold head; said bottom wall further having an internal cylindrical portion extending axially from the periphery of said bottom wall and having a thickness in the radial direction in excess of one dimension of at least one face of at least one electronic chip; and at least one recess formed into the exterior of said cylindrical portion which accepts at least one said chip into each said recess and which contacts at least a plurality of said faces of at least one said chip, whereby heat generated within said chip is conducted away from said at least one chip through any of a plurality of said faces, to said plate.
Claim 3
Dependent Claim
37 words
