HEAT PIPE

HEAT PIPE

ABSTRACT

       The transfer of the heat energy by conduction using solid material is essentially limited by thermal conductivity of that material. As the thermal conductivity increases cost of the material also increases hence it become costly. Because of the thermal energy is being transported by evaporation–condensation process rather than conduction. The heat pipe can transfer the heat much more effectively than the solid conductor of the same cross-section in practice conduction of heat by heat pipe may be several hundred (500) times that the best available metal conductor such as copper.
      Heat pipe system provides the maximum effective heat sink surface area with the minimum volume demand. A heat pipe heat sink is a passive cooling device that requires no moving parts, and operates silently and reliably. Additionally, heat pipe technology is emerging as a cost-effective thermal design solution. This paper explains the operation of heat pipes and its various applications.
