Abstract

This invention eliminates impact of hydrodynamic resistance of wicking material(s) while preserving high efficiency of capillary suction achievable by very harrow capillaries in design of heat transporting devices such as a heat pipe. It utilizes micro- or nano- porous membranes, in place of traditional wicks, placed across (normal to the vector of speed) the transport direction of the liquid. Elimination of the resistance is achieved by positioning the membrane on surface of the liquid that forms an interface between the liquid and the vapor allowing vapor to condense on liquid surface creating extensive capillary pressure.
