Claim 8:
9. A cooling system comprising:
an expandable vapor chamber comprising:
a condenser side opposite an evaporator side;
a condenser side wick coupled to a condenser side wall;
an evaporator side wick coupled to an evaporator side wall; and
a vapor core positioned between the evaporator side wick and the condenser side wick, wherein the condenser side wall comprises a thermal shape-memory polymer having a transition temperature such that:
when the thermal shape-memory polymer comprises a temperature below the transition temperature, the evaporator side wall is in a retracted position and the vapor core comprises a first volume; and
when the thermal shape-memory polymer comprises a temperature above the transition temperature, the evaporator side wall is in an expanded position and the vapor core comprises a second volume that is greater than the first volume.
