Abstract
The optimization of industrial processes for maximum utilization of available energy has been a line of scientific research quite widespread recently. Many industrial applications require the use of heat exchangers with piped fittings, whether or not finned, operating in air-conditioning, refrigeration, heating, radiator and other engineering applications. The present work carried out a numerical analysis of the temperature gradient on the fins of a heat exchanger, in which the fins have straight rectangular or rectangular pine geometry. This analysis was performed employing the finite difference and finite element methods in a code designed on the MATLAB platform by manipulating the data provided from a heat exchanger to the classical boundary conditions on an extended surface. Finally, the results obtained show that the pin of rectangular profile presents greater efficiency when compared to the straight rectangular fin and that finite element method converges to the analytical solution with greater accuracy than the method of finite differences.
