Theoretical Design and Analysis of Gravity Assisted Heat Pipes

Abstract

Gravity assisted heat pipes are heat transfer devices that are extensively used for heat recovery and cooling applications. This paper presents a theoretical approach to the design of gravity assisted heat pipes. The variation of the heat transport limits is plotted for different wick structures, materials, working fluids in the heat pipe and heat pipe dimensions. To obtain the best case for heat transfer in gravity assisted situations, the lowest heat transport limit is compared for different wick structures of the heat pipe.
