Abstract


There are various methods employed to determine the performance of heat pipes and two-phase closed thermosyphons. Perhaps the most common method involves measuring the rate of heat transfer from the evaporator to the condenser section with a water cooled jacket surrounding the latter. This entails higher costs and requires extended testing times. A method is proposed here to obtain comparative performance test data on various heat pipes rapidly and economically. The method does not require fabricating a water jacket. It merely involves measuring and comparing the transient temperature of a pre-heated container of hot water obtained first without the heat pipe and then with the heat pipe immersed into the container. The more efficient system will result in faster cooling of the container. The method is demonstrated using a number of different thermosyphons employing both water jackets and air cooled finned condensers. Their performances are compared in the paper.
