Heatpipes are generally sealed copper tubes with a state change material in them (often and alcohol?) that boils at a low temperature at one end, and the vapor carries the heat to the other end. When it transfers the heat the other end of the heatpipe, it recondenses to a liquid and then it flows or wicks back to the other end. These are used in computer heatsinks and in solar heat collectors. They are very efficient at moving heat.
