Essay On Heat Pipe

Abstract— Heat pipe is the apparatus which is very much in talk as a heat transfer device in the recent scenario of heat transmission efficiently. Heat pipe applies the principle of evaporation and condensation of fluid to transfer heat. Heat pipe has wide range of applications in aerospace, electronics packaging, building thermal management, material processing, nuclear, thermo-electro-mechanical device, heat pipe, heat exchanger and thermo siphon designers and manufacturers; mechanical, electrical and civil engineering students. This review highlights the importance of heat pipes in the current market.

Keywords— Evaporation and condensation, electronics packaging, building thermal management

I. INTRODUCTION

The heat pipe was originated by Grover in Los Alamos for use in thermionic direct conversion devices. Isothermalization is its main feature as it is possible to control the temperature of operation of the pipe by introducing a controlled pressure of inert gas, such as helium or argon. A heat pipe is a two phase device with very high conductivity

They can easily be implemented as heat exchangers inside sorption and vapour-compression heat pumps, refrigerators and other types of heat transfer devices. Their heat transfer coefficient in the evaporator and condenser zones is 103−105 W/m2K, heal pipe thermal resistance is 0.01−0.03 K/W, therefore lead to smaller area and mass of heat exchangers. Miniature and micro heat pipes are welcomed for the electronic components cooling and space two-phase thermal control systems. Loop heat pipes, pulsating heat pipes and sorption heal pipes are the novelty for the modern heat exchangers. Heat pipe air pre-heaters are used in thermal power plants to preheat the secondary/primary air required for combustion of fuel in the boiler using the energy available in exhaust Hue gases. Heal pipe solar collector’s arc promising for the domestic
