Heat pipes are devices used for heat transfer that combine two principles: phase transition and thermal conductivity. These principles are combined in order to manage the transfer of heat that takes place between two solid interfaces. Where a liquid comes in contact with the hot heatpipe, this liquid turns into a vapor, which travels along the heat pipe until it reaches the cold interface where it condenses back into a liquid; this relseases the latent heat. The process repeats when the liquid then returns to the hot interface of the heatpipe again via capillary action or centrifugal force or gravity.
Heatpipes are very effective thermal conductors, though the specific thermal conductivity varies from heat pipe to heatpipe according to the length. Heat pipes typically are composed of a sealed pipe made of a material appropriate for the fluid that is being used. For example, copper is typical for water heatpipes, while aluminum is usually used for ammonia heat pipes. A vacuum pump is used to remove air from the empty heatpipe before a working fluid partially fills the heat pipe prior to sealing. Within the temperature range of the operating heat pipe, the heatpipe should contain both liquid and vapor.
Heatpipes date back to the advent of steam technology during the steam age, along with the “Perkins Tube” which was used widely in working ovens and train boilers. The term “heatpipe” wasn’t coined until 1963, when George Grover independently developed the technology at Los Alamos National Laboratory.
