INTRODUCTION
The idea of heat pipes was first suggested by R.S.Gaugler in 1942.In 1963, G.M.Grover invented its remarkable properties & serious development began.
A heat pipe is a device that efficiently transports thermal energy from its one point to the other. It utilizes the latent heat of the vaporized working fluid instead of the sensible heat. As a result, the effective thermal conductivity may be several orders of magnitudes higher than that of the Good solid conductor
A heat pipe consists of a sealed container, a wick structure, a small amount of working fluid that is just sufficient to saturate the wick and it is in equilibrium with its own vapor. The operating pressure inside the heat pipe is the vapor pressure of its working fluid. The length of the heat pipe can be divided into three parts viz. evaporator section, adiabatic section and condenser section. In a standard heat pipe, the inside of the container is lined with a wicking material. Space for the vapor travel is provided inside the container
CONSTRUCTION
It consists of a sealed hollow tube using thermo conductive metal such as such as copper or aluminum.. On the internal side of the tube's side-walls a wick structure exerts a capillary force. It is similar to a thermosyphon. The pipe Consists of a small amount of coolant and the rest of the pipe is filled coolant and the pipe with vapor phases of the working fluid.
Heat Pipe is thermal transfer devices that are capable of transferring heat seal hundred times faster than conventional methods.
Heat Pipe Structure: A traditional heat pipe is a hollow cylinder filled with a vaporizable liquid.
A. Heat is absorbed in the evaporating section.
B. Fluid boils to vapor phase.
C. Heat is released from the upper part of cylinder to the environment; vapor condenses to liquid phase
D. Liquid returns by gravity to the lower part of cylinder (evaporating section)
