Abstract

Heat pipes are heat transfer devices which are widely used due to their higher effective thermal conductivity in comparison with conductive metals such as copper and aluminum. Several kinds of heat pipes exist such as pulsating heat pipe, rotating heat pipe, wick heat pipe, vapor chamber and thermosiphons. Heat pipes contain a fluid which evaporates by receiving heat at evaporator and then the vapor is converted into liquid by heat dissipation in the condenser. Different types of heat pipes are classified based on the mechanism of return of condensed fluid from the condenser to the evaporator. Nanotechnology is mainly used in recent years to enhance heat transfer in different mediums as well as heat pipes in the form of nano-fluids or nano-surfaces. This paper gives a comprehensive review on the most recent applications of nanotechnology to enhance the performance of these heat pipes.
