Abstract The present study deals with the experimental research of heat transfer and air flow behaviour of pin fin heat sink with and without wings under forced convection. For inline and staggered arrangements of pin fins, the fin pitch ratio (S/D) and the wing size ratio (Lw/D) are varied for the Reynolds number range of 6800–15,100. The heat transfer rate and frictional losses are increased by decreasing the (S/D) and (Lw/D) ratios. The optimum performance corresponds to the the pin fin heat sink with wings having (S/D) ratio of 2 and (Lw/D) ratio of 0.2.
