Comparison of standard and heat-pipe fins with specified tip temperature condition

Analytical expressions for heat-pipe fin temperature distribution and effic iency were obtained for a fin with uniform cross-sectional area, convection , thermal conductivity, and where the fin-tip temperature is specified. The results were compared to a standard (solid conductor) fin. It was observed that under most conditions, the heat-pipe fin would have a higher efficien cy than a geometrically similar standard fin. The important parameters need ed to compare the two types of fins are presented.
