Abstract
Abstract A thermal conduction module for removing heat from one or more chips (12) located therein consists of a housing (18) made of heat conductive materials forming a cap over the chips. The housing contains one or more openings (22), one opposite each of the chips. More than one heat conductive element (26) is included in each of the openings and are free to move independently lengthwise within the opening. The heat conductive elements are spring loaded (27) so that the end of each element contacts the associated chip. Side springs (29) are located between the sides of adjacent heat conductive elements forcing them mutually away from one another and into contact with the wall of the opening (22).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
A thermal conduction module for conducting heat from a plurality of integrated circuit chips located therein, the module comprising a substrate (14) on which the chips (12) are mounted, a housing (18) made of heat conductive material sealed to the substrate and forming a cap over the chips, a plurality of elongated openings (22) in the inner surface of the housing each facing a respective chip, the longitudinal axis of each opening being at least approximately perpendicular to the respective chip, a respective heat conductive element (26) disposed in each of the openings and movable longitudinally thereof, and spring means (27) biassing the heat conductive elements into contact with the respective chips, characterised in that each opening (22) contains a plurality of independently movable heat conductive elements (26) each spring biassed into contact with the respective chip (12), and in that further spring means (29) are located between the heat conductive elements in each opening forcing them mutually away from one another and into contact with the wall of the opening.
Claim 2
Dependent Claim
171 words
A thermal conduction module for conducting heat from a plurality of integrated circuit chips located therein, the module comprising a substrate (14) on which the chips (12) are mounted, a housing (18) made of heat conductive material sealed to the substrate and forming a cap over the chips, a plurality of elongated openings (22) in the inner surface of the housing each facing a respective chip, the longitudinal axis of each opening being at least approximately perpendicular to the respective chip, a respective heat conductive element (26) disposed in each of the openings and movable longitudinally thereof, and spring means (27) biassing the heat conductive elements into contact with the respective chips, characterised in that each opening (22) contains a plurality of independently movable heat conductive elements (26) each spring biassed into contact with the respective chip (12), and in that further spring means (29) are located between the heat conductive elements in each opening forcing them mutually away from one another and into contact with the wall of the opening.
Claim 3
Dependent Claim
40 words
