Heat pipes are closed systems in which a fluid is evaporated in one section where heat is absorbed and recondensed in another section, where it is given up again. Water, because of its high latent heat of evaporation, can be used to produce heat pipes with high heat conductance but its use is limited at low temperatures by freezing. This can be overcome by the use of antifreeze additives such as alcohol, fluorocarbons, inorganic salts or silicone oils. The principle is claimed for all working fluids. The devices find application in space travel, cryogenics and for semiconductor elements. |
