Summary

AN ANALYSIS IS MADE OF HEAT TRANSFER FROM A PLATE FIN, WHICH IS COOLED BY FORCED OR NATURAL CONVECTION. APPROXIMATE EXPRESSIONS ARE USED TO RELATE CONVECTIVE HEAT FLUX AND TEMPERATURE IN THE CASE OF LAMINAR AND TURBULENT BOUNDARY LAYER IN FORCED FLOW AND IN THE CASE OF NATURAL CONVECTION IN A VERTICAL FIN. A SIMPLE SOLUTION PROCEDURE IS PRESENTED TO SOLVE CONJUGATED HEAT TRANSFER COMPOSED OF CONDUCTION IN A FIN AND CONVECTION FROM IT. MEANINGFUL HEAT TRANSFER RESULTS ARE OBTAINED WHEN HEAT TRANSFER OF AN ACTUAL FIN IS COMPARED WITH AN IDEAL ISOTHERMAL FIN. IT WAS FOUND THAT ONE CURVE IS ENOUGH TO PRESENT HEAT TRANSFER RESULTS WITHOUT PARAMETERS.
