Heat transfer analysis on different pin fin types using Solid Works

Abstract

A fin is an extended part of an object whose purpose is to raise the rate of heat transfer mainly by convection. The heat flow in any object depends on the surface area, temperature difference, and convection coefficient. As convection coefficient cannot vary after a certain limit and temperature difference depends on the process, the way to increase the rate of heat transfer is to increase surface area which was done by adding fins. In this study, steady-state thermal analysis is performed on different types of fins and fins of different heights by using Solid works simulation. Different materials of fins are also used to verify results as the rate of heat transfer is independent of material. Aluminum 6061 and Copper is used as material for rectangular and cylindrical pin fins. In comparison, rectangular pin fin has a high rate of heat transfer as compared to copper pin fin, and also the rate of heat transfer is directly proportional to the height of the fins irrespective of the profile.
