Abstract:
1. An article for cooling a heat-dissipating component comprising: a substrate; an expansion chamber comprising at least one sidewall substantially impermeable to fluid, said sidewall defining an enclosed volume that is expandable between a first volume and a second volume, said sidewall comprising a proximal terminal end affixed to and contacting said substrate, a distal terminal end opposite said proximal end and not contacting said substrate, an inner surface proximate said enclosed volume, and an outer surface opposite said inner surface, wherein said sidewall extends between said proximal terminal end and said distal terminal end; and a quantity of heat transfer fluid disposed within said enclosed volume; wherein said distal terminal end moves from a first position proximate said substrate to a second position away from said substrate as said enclosed volume expands from said first volume to said second volume.
