Abstract
This numerical study applies Constructal Design to find the shape of a finned assembly that provides the most effective heat removal by means of convection. Here a rectangular heat generating medium is cooled by five finned assemblies with 3, 5, 7, 9 and 15 number of rectangular fins. Both, the assembly of fins and the heat-generating medium, are made of cooper and the numerical solution assumes a perfect thermal contact between them. In order to find the configuration that reduces most the overall thermal resistance of the whole system a numerical code based on finite elements and developed in MATLAB environment is used to solve the temperature field in the domain for all geometrical configurations studied. In this context, the area of the heat-generating medium and the total area of the system, as well as the thermal conductivities are kept constant.
