Abstract
A heat exchange component includes a part configured for exchanging thermal energy, the part is formed of at least one solid state Martensitic transformation phase change material which is configured to readily undergo a solid-solid martensitic transformation from one crystalline structure to another different crystalline structure during a change in temperature in the normal and/or anticipated operating temperatures of the heat exchange component. In some embodiments, the system further includes a temporally-evolving external temperature/heat source which changes the temperature and resultant phase of the solid-state phase change material. The temporally-evolving external temperature/heat source may involve a solid conducting material or electronic/photonic component, a fluid, a plasma, and/or a radiation source. The heat exchange component may be configured as a flat plate, tube, finned structure, porous structure, graded structure, cold plate, heat exchanger, condenser, evaporator, or any component generally regarded as a thermal energy storage or heat transfer structure in various embodiments.
