What are heat pipes?
A heat pipe is a device has an extremely high thermal conductivity, and is used to transport heat. In order to achieve this, heat pipes take advantage of simple physical effects:
As a liquid evaporates, energy - in the form of heat - must be taken from the environment. Therefore, an evaporating liquid will cool the surrounding area. This is how a heat pipe effectively cools the heat source. However, this doesn't get rid of the heat; heat is just transported with the vapor. At the target side for heat transport, the heat pipe must be cooled, for example using a heatsink. Here, the inverse effect takes place: The liquid condenses, and therefore emits heat.
Using these effects, it is possible to build heat pipes that have a thermal conductivity that is many thousand times higher than a copper piece of the same size. Note that unlike Peltier elements, a heat pipe does not consume energy or produce heat itself. It is also not possible to cool a device below ambient temperature using a heat pipe.
