CFD ANALYSIS OF INCLINED JET IMPINGEMENT MICRO-CHANNEL HEAT SINK USING NANOFLUIDS

Abstract

In this study, the inclined jet impingement micro-channel heat sink is used for electronic cooling applications. This study focuses on analysis of 3D micro-channel heat sink. Different types of nanofluids were used for the study. The fluid flow and heat transfer characteristics has been simulated using computational fluid dynamics in rectangular micro-jet impingement. The bulk mean temperature of nanofluid at the outlet and the average interface temperature have been analyzed. The geometry of the micro-jet impingement heat sink was constructed using SOLID WORKS design software and the simulation was performed on ANSYS FLUENT solver. In the present study, focus is put on increasing the heat transfer using the nanofluid. The jets used were placed at an inclination of 45 degree from the top surface of the impingement heat sink. The study is simulated using 6, 10, 14, 18 jets with diameters i.e. 0.1 mm. Copper was used as the solid material and nanofluid(water as base fluid) was used as a cooling fluid (working fluid). The results obtained were compared with the results of base fluid. The results showed that 1% TiO2 in water gave maximum bulk mean temperature at outlet which denoted that it had the maximum temperature change.
