Classification: CPC H | IPC H

Claim 7:
8. A heat sink assembly for use with at least one heat-emitting component, comprising:
a first frame including a first number of first chambers configured to hold a first phase change material that changes phase at a first temperature where the first frame has at least a portion conductively coupled to the at least one heat-emitting component;
a second frame including a second number of second chambers configured to hold a second phase change material that changes phase at a second temperature, which is greater than the first temperature, wherein the second number is different from the first number; and
a separate conductive element defining a structural barrier between the first phase change material and the second phase change material and conductively coupling the first phase change material and the second phase change material comprising a plate and a first set of fins cantilevered from the plate extending in a first direction into respective ones of the first chambers, and a second set of fins cantilevered from the plate and extending in a second direction into respective ones of the second chambers, the first direction being opposite the first second direction;
wherein the first phase change material changes phase in response to a conductive transfer of heat from the at least one heat-emitting component and the second phase change material changes phase in response to a conductive transfer of heat from the first phase change material.
