Thermal Modelling and Numerical Investigations on a Double Layered Microchannel HeatSink

Abstract
1-D thermal model is developed in the present study to find the complicated relationship between the overall thermal performance of a DL-MCHS with counter flow configuration, different geometrical parameters and flow conditions. Numerical investigationsarealso carried out to analyse the thermal resistance, pumping power and temperature distribution in the substrate of a DL-MCHS. The results of the present study show a good agreement of the developed 1-D thermal resistance model of a DL-MCHS with the existing literatures and present numerical results. It is observed that the thermal resistance is decreased by 6.01% and temperature uniformity is increased by 42.57% for counter flow DL-MCHS as compared to SL-MCHS with similar geometric and flow configurations.
