Abstract
Thermal management systems and methods of operation include a phase-change element including a phase-change material configured to change in phase state as the phase-change material absorbs heat and a plurality of active particles arranged within the phase-change material, with the plurality of active particles configured to induce a motion of the phase-change material when subjected to an applied electromagnetic field.
Claims20
A thermal management system comprising:
- a phase-change element comprising a phase-change material configured to change in phase state as the phase-change material absorbs heat;
- and
- a plurality of active particles arranged within the phase-change material, the plurality of active particles configured to induce a motion of the phase-change material when subjected to an applied electromagnetic field.
A method of removing heat from a heat load, the method comprising:
- arranging a phase-change element in thermal contact with a heat load, wherein the phase-change element comprises a phase-change material having a plurality of active particles arranged within the phase-change material, the plurality of active particles configured to induce a motion of the phase-change material when subjected to an applied electromagnetic field;
- and
- applying an electromagnetic field to the phase-change element to induce a motion of the plurality of active particles and cause motion of the phase-change material.
