The micro channel heat sinks play a very important role in the functioning of the micro-electronic components. In this paper the focus is on the convective heat transfer performance of the micro channels with different geometric configurations. The heat transfer performance is a function of surface area available for the heat transfer and the heat transfer coefficient of the heat carrying medium. An experimental heat transfer analysis is carried out with different configurations of micro channels. Micro channels with four different configurations are fabricated using Photo Chemical Machining Process. The performance analysis is done in the Reynolds Number range of 15 to 50, with different inlet flow velocities and the experimental analysis emphasis the fact that the geometrical configuration of the channel has a considerable effect on the micro channel heat transfer performance and in turn on the performance of the micro-electronic components.
