CFD ANALYSIS OF INCLINED JET MICRO CHANNEL IMPINGMENT HEAT SINK

Abstract

In this study inclined jet micro channel impingement heat sink used for electronic cooling application several particles and staggered inclined micro-jet configuration will be used for study. The effectiveness of inclined micro jet configuration will be analyzing at various flow rates for the maximum temperature-rise and pressure drop. The shape optimization of a micro-channel heat sink with a grooved structure has been performed using a multi objective evolutionary algorithm. In the study inclined jet micro channel impingement focus on electronic cooling in micro level. In the study of inclined jet impingements focus on 3D micro channel for fluid flow ansys. The jets used have been placed at an inclination of 300,450,600 from the top of the surface .during this process copper has been used as the solid and water has been used as a fluid. The optimum results were obtained by using the jets at an inclination of 450. This study simulated six basic materials in inclined jet micro channel at 450 at water as a fluid. During study simulation carried out on copper, steel, nickel, silicon, titanium, and aluminum. After the simulation copper show maximum temperature drop through the metal. During the simulation difference in temperature and heat transfer coefficient define maximum heat transfer through the micro channel. In the study using four fluids in micro channel such as water, DIUF- water. HF-7200 and performance fluid (PF- 5060). During analyzing we have obtained optimum result through micro channel. Performance fluid gave maximum temperature drop through micro channel. During the simulation Nusselt number (Nu) show with respect to temperature drop. In the study of incline jet micro channel impingement heat sink all conclusion are made with respect to the fluid flow through in it. Flow define the characteristics of fluid such laminar or turbulent. During the iteration we have justified the solid material such as copper maximum heat transfer from the micro channel. Performance fluid provided maximum temperature drop through micro channel. It is a compactible study through the micro channel. For the best result study on Nano fluid used in micro channel. In the simulations we used Nano fluid mixture of water and Cuo in the volume fraction. During the simulation volume fraction of Cuo and water is 0.1%, 0.5%, and 1.5%. During the simulation we have found maximum temperature drop for 0.5% of Cuo and water mixture.
