The numerical study on the effect of heat transfer and flow distribution in I path micro channel (IPMC), U path micro channel (UPMC), Z path micro channel (ZPMC) heat sinks using nano fluids for inlet velocity of fluid range of 2-12 m/s. In this work, micro channel using Cu-Gnp and Fe3O4 water based nano fluids with constant volume fraction 1 % was used in coolant in micro channel. Governing equations are discredited using finite volume method in laminar fluid flow conditions. Results indicated increase in heat transfer coefficient due to decrease in thermal resistance of the micro channel by increasing inlet velocity at constant heat flux. They also indicated increase in pumping power due to decrease in friction power of the micro channel by increasing inlet velocity. Under constant heat flux conditions, cooling effect of micro channel enhanced further by adding Cu-Gnp and Fe3O4 Nano particles to the base fluid water. Pressure drop of water based Nano fluids across the IPMC, UPMC, and ZPMC increased slightly compared to water cooled micro channel.
