Planar Bridging-Droplet Thermal Diodes
Abstract
Traditional thermal diodes are limited by an inherently 1D form factor (e.g. liquid-trap heat pipes) or by gravitational dependence (e.g. thermos-syphons). Exploratory work demonstrated a thermal diode with jumping-droplet liquid return by utilizing a nanostructured super-hydrophobic condenser, but these condensers are not durable under sustained operation. The PI proposed to develop a fundamentally new type of thermally adaptive material system called a planar bridging-droplet thermal diode, which should be at least 100 times more thermally conductive in one direction compared to the reverse direction and operate independently of gravity and inertia.
