Abstract

This invention encompasses a water-to-water heat-pipe heat exchanger having vessel, at least one partition dividing said vessel into at least two compartments, at least one of said compartments further having a fresh water input means and a fresh water output means, and a different compartment having a hot waste water input means and a hot waste water output means, and a plurality of heat exchange pipes for transferring heat between said compartments. The invention is generally in heat exchangers, and for dissipating heat in any system by transferring heat from a hot to a cool substance. Such a system may be used to alleviate the excessive heat generated during thermonuclear reactions, wherein cool water is exposed to a vessel containing hot waste water to cool the temperature of the waste water, such that no mixing or interchange of hot and cool water occurs. Alternatively, the heat exchanger described herein may be used to conserve heat generated in a system whereby one or more components utilized therein must be heated prior to chemical reaction. For example, wherever a hot solvent system is used to extract or purify a contaminant or other compound, the heat contained in the was…
