EXPERIMENTAL ANALYSIS OF HEAT PIPE

EXPERIMENTAL ANALYSIS OF HEAT PIPE

ABSTRACT:

The world today is standing forward for the ways and means of quickly and efficient transfer of heat from one point to another. Richard S. Gaugler first suggested a device for this purpose in 1942. Then G.M.Groover invented it in 1962, which he named as ‘Heat Pipe‘.
A heat pipe acts like a conductor. It is a simple device that can quickly transfer heat from one point to another. The basic heat pipe is a closed container consisting of a capillary wick structure and a small amount of vaporizable fluid. The heat pipe employs an evaporating condensing cycle, which accepts heat from an external source, uses this heat to evaporate the liquid (Latent Heat) and then releases latent heat by reverse transformation (Condensation) at a heat sink region. This process is repeated continuously by a return feed mechanism of the condensed fluid back to the heat zone by means of wick material.
The heat pipe has a single structure, very high effective thermal conductance and heat transfer capacity, and can work in hostile high temperature environments. In this paper, the performance characteristics of heat pipes are investigated and its performance is discussed from the experimental results and graphs.
