A systematic experimental investigation was conducted to evaluate the heat Transfer characteristics of a copper-nickel multi tube with corrugated copper fins in a cross flow heat exchanger. The heat transfer rate from a tube can be augmented either by increasing the surface area, by number of fins or by creating turbulence in the flow. Experiment was carried out under the copper fin tube type heat exchanger in which no. of fins is mounted along the full length of heat exchanger. The effect of no. of fins on a full length heat exchanger on the heat transfer coefficient was experimentally investigated in case of different mass flow rate of water and air. The performance evaluation of cross flow heat exchanger with copper fins was carried out for water temperature varying from 38°C to 64°C and water velocity 0.07735m/s to 0.271m/s and air velocity 3.194m/s to 14.52m/s. It was found that on the basis of different flow rate of water and air heat transfer coefficient increases constantly on the water and air side respectively.Keywords
