Abstract: In this paper we have used second law of thermodynamics. Fourier law and Newton’s law of cooling, fin equations is used to solve a variety of steady heat conduction problem. The Problem is solved computationally using ANSYS Software. Analytical results were obtained for cooling fin. Convection is found to be along with all the boundaries of the assembly except the lower most, which is fixed to the steel block. The film coefficient is taken to be 50 W/m2K and the Bulk (ambient) Temperature is taken as 293 K. The block will be containing a copper/aluminium heating element that releases heat, totaling to 27.2 W. The other boundaries of the steel block are insulated to prevent the loss of heat energy. Due to temperature difference heat will flow from higher temperature to lower temperature. Fins were used to increase heat transfer rate. Result obtain were nodal temperature distribution and maximum value temperature in the component. we will also see how temperature varies with different thermal conductivity of material. With the help of MATLAB graph has been plotted to make it more understandable.
