SEMINAR ON HEAT PIPE HEAT EXCHANGER

HEAT PIPE HEAT EXCHANGER

A heat pipe is a heat transfer mechanism that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two solid interfaces. 

At the hot interface within a heat pipe, which is typically at a very low pressure, a liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing the heat of that surface. The vapor condenses back into a liquid at the cold interface, releasing the latent heat. The liquid then returns to the hot interface through either capillary action or gravity action where it evaporates once more and repeats the cycle. In addition, the internal pressure of the heat pipe can be set or adjusted to facilitate the phase change depending on the demands of the working conditions of the thermally managed system.

n Heat Pipe or heat pin is a heat-transfer device that combines the principles of both thermal conductivity and phase transition to efficiently manage the transfer of heat between two interfaces.

n heat pipe is a vacuum tight device consisting of a working fluid and a wick structure.

nIt consist evaporator section, wick structure and condenser section.

nThe condensed liquid returns to the evaporator through the wick structure by capillary action.
