EXPERIMENTAL STUDY OF HIGH HEAT REMOVAL BY ALUMINUM PIN FIN HEAT SINK USING MULTI-JET AIR IMPINGEMENT

This Experimental Study utilizes the multi-jet impingement technique to investigate the thermal performance of pin fin heat sink under unconfined and semi confined conditions. In the present Experimental investigates the effect of Aluminum Heat sink, nozzle jet exit Velocity, the jet to jet spacing and the nozzle plate to Flat plate heat sink or pin fin base plate Separation distance(Z/D) in a 3×3Square Multi-jet impinging array on average Nusselts number. Thermal Performance of Pin fin heat sink of 60×60×6mm for the Reynolds numbers range 6000 to 12000 is studied. The thermal performance of 4×4array circular Pin fin heat sink is studied with the thermal Parameters like Average Nusselts number, total thermal resistance, Average base temperature, Reynolds numbers.
