Abstract

The overall performance of microchannel heat sink (MCHS) as a system is affected by the inlet and outlet manifold arrangements in addition to array of microcannel. In the present study the CFD analysis is performed w.r.t the heat transfer coefficient, and Nusselt number for three different manifold arrangements. In the present work three different arrangements: Rectangular (R), Rectangle with Semi-Circular (RSC) and Divergent Convergent (DC) of the inlet and outlet manifolds are selected. The result shows MCHS within the Reynolds number ranging from 342-857, the DC type manifold has highest heat transfer coefficient (9%-10%) in comparison to RCS and R type manifold being the lowest.
