摘要

In certain applications geometric constraints may make it impractical to use a straight thermosyphon. This paper aims to characterize the performance of a counter-flow thermosyphon with varying bend angles in the adiabatic section and a range of fluid loadings. The results of this study demonstrate that adequate levels of heat transfer can be achieved with bends in the adiabatic section connecting the evaporator and condenser sections. In general the effects of bend angle and fluid loading had relatively little effect on total thermal resistance. Finally, the failure limit of each thermosyphon was characterized. It was clear from the results obtained that further work is necessary to expand the range of testing parameters to fully understand their influence on the performance of the thermosyphon.
