Development of an osmotic heat pipe
Abstract
The osmotic heat pipe differs from a conventional heat pipe in that a semipermeable membrane, instead of a capillary wick, is used to pump liquid from the condenser to the evaporator. Basic performance characteristics, membrane materials and some problem areas in the design of these new devices are described in detail. An experimental apparatus has been designed and built to measure solvent permeation rates as well as membrane semipermeability. Test results are presented for two membrane samples using an aqueous sucrose solution.
