1. A heat exchange component comprising:
a part configured for exchanging thermal energy, said part formed of at least one solid state (SS) Martensitic transformation (MT) phase change material (PCM) 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 and a transition between crystalline structures does not involve or result in physical deformation of the part; and
wherein the part is a heat exchange structure selected from the group consisting of: a heat spreader, a heat sink, a condenser, a radiator, a fin or fins, and a fluidic channel; and wherein the component is configured to exchange thermal energy with a thermal transfer fluid that is internal and/or external to the component.
