Summary:The paper analyzes heat transfer in a longitudinal rectangular composite fin. Temperature-dependent thermal conductivity is carried out for forced convections with the aid of pin-fin apparatus. The fins used are electroplated and the base material is covered with a coating of another metal (say, copper coating on aluminum by hydrolysis) which has higher thermal conductivity than the base metal. The rate of electroplating by which the metal deposition takes place is 0.25 micrometers/min (approx.). The sulphates and nitrates of corresponding metals to be deposited are used in performing electroplating. Then the composite rectangular fin is analyzed on different parameters. The results are further validated using ANSYS.
