Analytical Comparison of Constant Area, Adiabatic Tip, Standard Fins, and Heat Pipe Fins

An expression is derived for a constant area, adiabatic end condition, heat pipe fin efficiency. The expression is used to compare the performance of a heat pipe fin with a standard fin. An analytical expression for the heat pipe fin temperature distribution and efficiency were obtained. The results...

Zusammenfassung:An expression is derived for a constant area, adiabatic end condition, heat pipe fin efficiency. The expression is used to compare the performance of a heat pipe fin with a standard fin. An analytical expression for the heat pipe fin temperature distribution and efficiency were obtained. The results show that heat pipe fins may not always be more efficient than standard fins, but they usually are. (AIAA)
