A heat pipe is an extremely efficient thermal conductor. Typically, a heat pipe consists of a sealed container (usually aluminum or copper), a wicking structure and a small amount of working fluid under its own pressure. Applying heat anywhere along the surface of the heat pipe causes the liquid at that point to boil and enter a vapor state. When that happens, the liquid picks up the latent heat of vaporization. The gas, which then has a higher pressure, moves inside the heat pipe to the colder location where it condenses. The condensed fluid travels back along the wick and repeats the process [continuously as long as there is heat at the evaporator end]. Far more conductive than copper of the same weight, heat pipes conduct large volumes of thermal energy away from the heat source.
