HEAT PIPE - HIGH PERFORMANCE TECHNOLOGY IN HEAT TRANSFER

Abstract

The basic heat pipe consists of a vacuum chamber from which all non-condensable gases have been discharged and which contains a capillary structure and a certain amount of two-phase fluid. However, a more general definition can be given, as the concept has since become much more comprehensive. Thus, the thermal tube is a device that achieves an efficient heat transfer by combining in a closed cycle the phenomena of vaporization, vapor transport, condensation and condensation return, of a working fluid. At first glance, the operation of the heat pipe seems to be extremely simple. The thermal energy is transported from the evaporator to the condenser through a continuous cycle of mass transfer and phase change of a working fluid.
