Patent ID: 8758892

Claim:
A system comprising a compressible thermally-conductive foam interface pad disposed intermediate a heat generating member and an opposing thermal dissipation member to provide a thermal pathway there between, said interface pad comprising: a cured elastomeric polymer, the elastomeric polymer having a cross-section and two opposing faces; and a thermally-conductive particulate filler loaded in an amount ranging from 20 to 80% by weight of the interface pad, said filler dispersed in the cured elastomeric polymer, said interface pad in the form of a single pad containing a plurality of regularly spaced air-filled voids mechanically formed in the pad, said voids extending completely through the pad from one opposing face to the other, said pad having an open area of between about 5% and 20%, a thermal impedance in the range from 1.0 to 1.6° C.-in 2 /W, and a 50% compression deflection in the range from 25 to 38 lbs.
