: A variety of heat sinks were used in compact electronic circuits under fan impingent flow for good thermal performance. The following study will examine the effect on overall thermal performance associated with different fin geometries, including, rectangular plates as well as square, circular, elliptical, offstrip, centrifugal heat sinks. The results clearly indicate that the preferred fin profile is very dependent on these parameters. In this paper the different geometries of heat sink, flow configuration, cost, and arrangement of pin fin heat sink studied. The present experiment investigate the effect of circular pin fin heat sink, jet velocity, jet to jet spacing, and nozzle plate to heated surface separation distance in 3×3 square multi jet impinging array on the average nusselts number. The jet Reynolds Number is varied in the range of Re=6000-13000.The thermal performance of 4×4 circular array pin fin heat sink studied with thermal parameters like average Nusselts number, total thermal resistance, average base temperature, Reynolds numbers. The multi jet impingement shows average heat transfer coefficient increases with increases in Reynolds number, total thermal resistance decreases with increases in Reynolds number.
