Performance Study of Different Types of Heat Pipes

Abstract

Despite the abundant studies on heat pipes over the last fifty years, the development of analytical tools for the design of heat pipes remains challenging, even for conventional technologies. As a result, heat pipes are still the object of more than 250 scientific articles a year. A brief overview of the heat pipe history is given and the different applications are presented. The different types of heat pipes are tested in different conditions that are under forced and free convection to identify the performance of different kinds of heat pipes. In natural convection conditions, heat input is increased from 20 to 35V and surface temperature is observed then by using correlations we try to find out h (heat transfer coefficient), and a comparison is made between analytical and experimental h ( heat transfer coefficient). Similarly in the case of forced convection by varying velocity between 9m/s to 30m/s and keeping heat input constant that is 20V we try to find out heat transfer coefficient experimentally and then compare that heat transfer coefficient with the analytical heat transfer coefficient which we obtain using correlations.
