Abstract: All engineering systems under operations generates heat. If this heat is not removed periodically the system will fail due to overheating of components. Hence, extended surface or fin are used to remove the heat from the system. In this paper experimental study on aluminium rectangular fins with triangular, rectangular and circular perforated fins are made under forced convection mode with different voltages, air velocities and fin spacing of 8 mm. Results are compared with solid fins with perforated fins of same spacings. Results shows significant increase in heat transfer rate for perforated fins compard with solid fins under some conditions also there is a weight reduction up to 23.6% compared to solid fins.
Keywords: Fins, Forced Convection, Heat Transfer co-Efficient, Perforated Fns.
