Abstract:

Heat exchanger is one which is used to transfer the heat from to cold one. Traditionally copper is the material which is used as heat transferring medium because of its high conductivity. Whereas gold and silver has more conductivity but they are more expensive. While next to the Copper Aluminium is consider as the heat transferring material. Here both Copper and Aluminium is introduced in heat exchanger and finding their heat transfer rates. Then it is compared to the existing model of Copper heat exchanger and Aluminium heat exchanger. The Heat exchanger is to fabricate is Single shell pass and two tube pass. The Heat transfer rates and effectiveness is been determined by NTU (Number of Transfer Units) method. Whereas LMTD (Logarithmetic Mean Temperature Difference) method is also used. Mass flow rates of Hot fluid  and cold fluid is kept same also hot fluid and cold fluids are been same.
