AbstractWith the advancements of technology employment of micro electronic devices isincreasing everyday Because of extreme compaction these devices encounter hightemperatures Increase of temperature results in the decrease of durability Therefore cooling is an important issue Many approaches are presented in order to solve thisproblem One of the most effective alternatives is using micro channels that are mountedon these devices The channels are constituted by solids with high conductivity throughwhich coolant is flown Obviously many parameters are involved in the design and performance of micro heatexchangers Consequently experiments and analyses of one of them is costly and timeconsuming Hence one appropriate way is numerical simulation In this work rectangular micro channels are simulated and analyzed Subsequently temperature distribution distribution of thermal flux pressure gradient and the temperatureof micro electronic devices in single and multi layered micro channels are analyzed andtheir thermal resistances are compared The results show better performance of thisapproach compared with single layered one Finally the effects of the number of layers pump strength the coolant inlet velocity Reynolds number the aspect ratio and the massflow inlet are analyzed on the thermal resistances of rectangular micro channels Somesuggestions are made to improve the introduced system
