Thermal Analysis of Fin: Comparative Thermal Analysis

Abstract

The fins are extended surfaces that are made to increase the rate of heat transfer through the equipment/components. Generally, they are used for faster cooling of the equipment/components. The comparative thermal analysis of rectangular fin and porous fin is done in the paper. Both the fins are subjected to the same conditions i.e., both the fins have the same room temperature, have the same dimensions, and are exposed to the same surrounding conditions i.e., the flow of air over the fins, the ambient temperature of the fins, etc. Of course, for calculations, some assumptions are made. The heat transfer rate from both fins is calculated and compared. The efficiency of fins and effectiveness are calculated and compared. The temperature distribution graph for the rectangular fin is plotted in Excel. The modeling software Solidworks is used to model rectangular non-porous fin and rectangular porous fins. The thermal analysis of both the fins is done in the software called Simscale.
