Maniks Heat Pipe A Very Efficient Way to Transfer Heat

Heat Pipe is a very simple device which is applicable in the energy conservation applications. Maniks is conventional supplier of efficient and cost effective heat pipe to exchange heat from source to desired location with very high thermal conductivity. It is a very important invention by George Grover in early 1960s which is been applicable in many applications. Now a days it is been widely used in the applications from handhold devices to aerospace elements. He has independently developed heat pipe for Los Alamos National Laboratory to avoid waste of heat energy from energy conservation system.

Operating principle

It provides very high thermal conductance when designed properly and it is a passive heat transfer device. The working of heat pipe is base on the principles of both high thermal conductivity and phase transfer. It enables transfer of heat by the action known as “Capillary Action”. There are three major elements in heat pipe responsible to transfer heat namely:

  • Working Fluid

It transfers heat energy from one point to another by the process of evaporation and condensation. The fluid is reticulated inside the vacuum tube by means of the forces known as “Capillary Forces” because of which process of transfer of heat is carried out automatically.


  • 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.
