Thermal ground planes (TGPs) are passive thermal management devices that utilize the phase-change of a working fluid to achieve high conductivity and low resistance. TGPs flat, two-dimensional heat pipes—similar vapor chambers—in which liquid is held within capillary wick, in sealed layer. Heat absorbed at an evaporator region, causing evaporate. The heated core carried via convection condenser region where it condenses as expelled from TGP external sink. condensed then pulled back forces...
Searching for new materials with extra low thermal conductivities is significant in numerous fields like barrier coatings and thermoelectric devices.
