The vaporized fluid then condenses back to liquid (cold-end) and the heat is dissipated into the air from the metal cooling fins. The working fluid returns to the hot end via capillary action thru an internal wicking structure (sintered metal coating, fine wire mesh, or grooves) so the heat pipe does not have to rely on gravity to recycle the working fluid. The key to a heat pipe's high efficiency is the latent heat of vaporization.
OK... now I understand....
but still.... do heatpipes really able to transfer a lot of thermal energy that fast?
All the heat traped by the liquid will be brought to a cooler place to dissipate the heat by cappilary action or convection or depressurization ......Hence less time .
While , Metal as Stationary phase need more time to overcome thermal resistance to transfer by conducting heat from Hot area to cold area ..
The time make the diffrence , Liquid Heatpipe have faster inner heat transfer ....
