WebHeat pipes are evacuated vessels, typically circular in cross section, which are back-filled with a small quantity of working fluid. They are totally passive systems, with no moving parts, and transfer heat from a heat source to a heat sink with minimal temperature gradients, or to isothermalize surfaces. How does a heat pipe work? WebThere are three ‘parts’ to a heat pipe that allow it to work: a vacuum sealed enclosure, a wicking structure, and a working fluid. By a large margin, the most common type is a copper enclosure, a sintered copper wick structure that bonds to the interior surface, and de-ionized water as the working fluid.
