Heat Pipe Solutions

Passive, high-conductivity heat transport — over distance, in any orientation.

A Heatpipe is a "two phase" heat transfer mechanism with extremely high "effective" thermal conductivity. A thin walled pipe with an internal wick structure allows boiling and condensing of the working fluid to occur within the pipe resulting in heat transfer from the hot end to the cooled end. Small volumes of liquid evaporate at the hot end, even at low temperatures due to the vacuum inside the pipe, and condense on reaching the cooled end, giving up its latent heat. The condensed liquid then wicks its way back to the hot end by capillary action and/or gravity and the cycle repeats.
