The current primary NASA target application for the proposed space-rated flexible 2-phase thermal strap technology is future CubeSat and SmallSat spacecraft. In particular, the proposed thermal strap will enable efficient heat transfer by dissipating a wide range of heat loads in widely varying environments. Further, the thin, flexible construction of the thermal strap will use less of the limited spacecraft mass and volume. Beyond NASA applications, the proposed thermal strap technology could see use in other military and commercial applications where thermal management is also a considerable need. Terrestrial-based applications include military and commercial aviation, military and consumer electronics (e.g., computers, cell phones, etc.) among several others.
