Wick Capillary structure
This wick capillary structure is responsible for the circulating the liquid
from condensation to evaporator end with the help of capillary forces.
Vacuum Sealed tube
It is also called as heat pipe envelope which provides a leak tight
pressure vessel for working liquid. This structure can be made up of
aluminum, copper, titanium, stainless steel, tungsten etc. most
common tubes of Heat pipe is made from the copper.

How it Works?
The one end of heat pipe is placed in the heat generation section, when one
end of the pipe is heated temperature of the liquid inside the heat pipe will
also increases gradually and after large temperature increase it vaporizes.
These vapors travel towards the colder end and carries latent heat
associated heat with it. At colder end vapor dissipates all the latent heat and
turns back into liquid form this liquid then travels back to heated end. The
capillary wick structure helps liquid to travel back to the evaporator end with
the help of centrifugal forces. This process is carried out continuously and
the heat transfer takes place through a very safe effortless way.
Phase-change processes and the two-phase flow circulation in the heat pipe
will continue as long as there is a large enough temperature difference
between the evaporator and condenser sections. The fluid stops moving if
the overall temperature is uniform, but starts back up again as soon as a
temperature difference exists. No power source (other than heat) is needed.
In some cases, when the heated section is below the cooled section, gravity
is used to return the liquid to the evaporator. A wick structure is required
when the evaporator is above the condenser on earth. A wick is also used
for liquid return if there is no gravity, such as in NASA’s micro-gravity
applications.
