Type of article: Article

Summary

The profile of the least-weight longitudinal cooling fin is obtained considering temperature dependence of thermophysical properties. A power-law-type wall heat flux is assumed on the lateral and tip surfaces of the fin. Uniform temperature is imposed at the fin base, whereas two kinds of boundary conditions at the fin tip are considered. Special cases of negligible heat transfer from the fin tip and zero tip temperature are investigated. The temperature distributions and profiles of the optimum fins are calculated for various single heat transfer modes.
