Patent ID: 8110746

Claim:
A structure, comprising an interposer adapted to be interposed between a heat source and a heat sink and to transfer heat from the heat source to the heat sink, said interposer comprising an enclosure that encloses a cavity, said enclosure being made of a thermally conductive material, said cavity comprising a thermally conductive foam material therein, said foam material comprising pores and comprising at least one serpentine channel, each serpentine channel having a plurality of contiguously connected channel segments, each serpentine channel independently forming a closed loop or an open ended loop, said foam material having a characteristic of being soakable by a liquid filling said pores, each serpentine channel having a characteristic of being partially fillable with a fluid that serves to transfer heat from the heat source to the heat sink, wherein the channel segments of a first serpentine channel of the at least one serpentine channel are disposed at a same planar level within the interposer, and wherein the planar level is perpendicular to a thickness direction of the interposer.
