Present work is based on the numerical analysis of pin fin heat sink using splitters. Splitters were provided on fins and the optimum angle is determined using CFD analysis. The splitter with fins arrangement for heat sink are the extended surfaces that are extending from an object to enhance the rate of overall heat transfer within the exposed surfaces by accelerating the rate of convection. Under the present investigation, attempts have been made to maximize the heat removal through heat sink by varying the angle of splitter in a ‘pin fin heat sink with splitter’ and using staggered orientation of fins. The results of numerical investigation prove that maximum heat transfer coefficient is observed at 35° splitter angle. The maximum heat transfer was found out for the configuration of splitters inclined at 35 degree angle with the direction of inlet air with heat transfer coefficient value of 318 W/m2 K using air velocity as 8 m/s.
