CFD ANALYSIS OF JET IMPINGEMENT TRANSFER OF HEAT IN MICRO CHANNEL

Abstract

This study evaluated a micro-jet impingement heat sink for the cooling of electronic field at micro level devices. In this study, we focused on the 3-D flow of different fluid through the channel and transfer of heat with jet impingement heat sink are simulate numerically using De-Ionized Ultra-Filtered (DIUF) water, water and Performance fluid (PF-5052) , HF-7100 was used as a coolant to flow through the micro-nozzles which is fixed to the channel. For the micro channel heat sink investigated and obtained that the temperature distribution along the flow direction in the solid and fluid regions have linear behavior. In this work we are using six different martial (copper , aluminium , steel , silicon , titanium , nickel ) which is used to make substrate of the micro channel and four fluid (water , De-Ionized Ultra-Filtered (DIUF) water, Performance fluid-5052, HF-7100 ) are used for flowing through the micro channel and heat transfer coefficient and temperature distribution is obtained . It is observed that Copper has the highest value of heat transfer coefficient as compared to the other materials as shown in the table 1. Copper and working fluid De-Ionized Ultra-Filtered (DIUF) water have the highest heat transfer coefficient and Nusselt number value. So that the micro channel which is made by copper with flow of DIUF water in the micro channel are used for better cooling results.
