Heat transfer principle of heat pipes

The heat-pipe process involves removing the internal air before injecting the working fluid and sealing it. Under low pressure, the vaporization temperature of the working fluid drops substantially.
The vaporization zone absorbs heat and vaporizes rapidly. The vapor moves towards the condensing zone and after exchanging heat with the external low temperature environment, it condenses into a liquid state and then flows back to the vaporization zone by gravity or capillary force and pressure difference of the pipe wall, and the cycle continues. The heat transfer coefficient is approximately 50-100 times higher than that of pure aluminum due to the two-phase fluid flow.
The heat pipe is characterized by fast temperature uniformity, being a passive element without the need to electrically drive an active mechanism such as a fan, and its light weight.
