    • A thermal conduction module for cooling one or more integrated circuit chips mounted on a substrate is described. At least one shim is disposed between the base plate and the cover plate of the module to establish a predetermined dimension between the cover plate and the integrated circuit chips mounted on the substrate for insertion of a thermal paste. The shims may be metal, engineered plastic, or thermally and electrically conductive or nonconductive creep resistant materials able to withstand the stress and load within the module over time. The shim may be a plurality of shims having the same thickness or a plurality of shims having a multiplicity of thicknesses. Most preferably, the shim conforms to the periphery of the cover plate or base plate. A method of determining the proper shim thickness is also described wherein an initial reading of the thickness of the cover plate and base plate of the module is obtained. A second reading of the thickness of the module is obtained after the substrate, mounted with at least one integrated circuit chip, is placed onto the base plate followed by a temporary spacer and the cover plate. One or more shims are selected which are equal to the difference between the initial reading and the second reading. The cover plate is removed and the spacer is replaced with the appropriate shim. The cover plate is then fastened to the base plate. Also described is a kit for fixing the thermal paste gap dimension in electronic modules comprising a base plate, cover plate, and a plurality of shims having a multiplicity of thicknesses.

    • The present invention provides a thermal conduction module assembly kit comprising a base being substantially planar in shape and adapted to receive on a top surface a substrate adapted to receive at least one integrated circuit having top and bottom surfaces. A cover is substantially rectangular, having top and bottom surfaces and an outer edge surface. The cover is designed to mate with the substrate such that the integrated circuit is positioned between the bottom surface of the cover and the top surface of the substrate. A removable shim member is planar in shape and has a definable vertical dimension positioned between the bottom surface of the cover and the top surface of the integrated circuit to provide a specified dimension between the top surface of the integrated circuit and the bottom surface of the cover. A positioning member has top, bottom, and inner surfaces, and is substantially circular. The inner surface of the positioning member is positioned to circumscribe and movably mate with the outside surface of the cover. The inner surface of the positioning member is affixable to the outer edge surface of the cover, and the bottom surface of the positioning member is contactable with the top surface of the substrate. The affixable inner surface of the spacer, and the bottom surface of the affixable positioning member, are capable of maintaining the vertical dimension between the bottom surface of the cover and the top surface of the integrated circuit defined by the specified vertical dimension of the shim member, and define a gap of the same specified vertical dimension after the removable shim member is removed. The gap substantially receives a thermally conductive medium.

    • An apparatus for cooling an array of integrated circuit chips mounted on a substrate comprises a thermally conductive cooling plate which has a plurality of integral, substantially parallel, closed-end channels. A cover which may be made of plastic is adapted to seal the periphery of the cooling member and is spaced from the channel-containing surface. The cover has a plurality of integral baffles extending toward the cooling member into and along the length of the channels. The baffles and the channels are spaced from each other to permit passage of a coolant between and through the channels in a flow direction normal to the channels. An inlet and outlet for the coolant are provided on opposite ends of the apparatus, and may be located in the cover. In an alternate embodiment, the cooling plate contains at least two sets of the channels, each set of channels receiving a separate flow of coolant, either in parallel or in series with each other.

    • A cooling device having a common cooling distribution unit with multiple compliant cooling elements. Mechanisms are built in to ensure the cooling elements are in good thermal contact with heat generating semiconductor chips of different heights and sizes on a common carrier. The cooling distribution unit has protection structures to prevent the leakage of coolant from the unit. Further reduction of the risk of accidental coolant leakage is provided with the onboard storage of coolant absorbent materials in the coolant distribution unit. The cooling elements have serpentine coolant channels to enhanced the cooling capacity. The compliance of the cooling elements can also be achieved by using concentric tubing to connect the coolant distribution unit to cooling heads on the cooling elements.
