Finite Element Analysis of Radiator Fins to increase the Convection Efficiency of Radiator by using Al Alloy, Cu and Brass Material

摘要

Radiator is a device which is used as cooling system in combustion engine by convection heat transfer method, in radiator the temperature of the water at entry of the tube is high when compared to the exit, so we predict the radiation in every sq mm by ANSYS and select the suitable alloy of brass to increase the radiation efficiency by force convection and free convection. Cooling performance is compared between automobile and aircraft radiator. This paper reports a study carried out using 3-D modeling and finite element analysis for radiator. Pro-E was used for 3-D modeling then by neutral file format the model was imported in to ANSYS. Here the solid model was converted in to finite element model Boundary conditions such as maximum temperature of the cylinder, convective heat transfer coefficient, ambient temperature and material properties such as thermal conductivity are used as set of parameters for the program. Heat flux and temperature profiles were used to measure the efficiency.
