Abstract
Parallel micro-channel heat sinks linked with a joint are investigated in this paper. Channels are analyzed for laminar flow (water) under constant heat flux. The considered channels with same hydraulic diameter (776 ) are investigated for two different dimensional variations of connecting link with parallel flow and the comparison of parallel and counter flow in the channels. It is found that the varying dimension of joining link has a little influence on the over-all thermal hydraulic performance. Performance index decreases in the cases of either increasing the height (J) or width (W) of the joint at higher Reynolds number (1000 and 1200). Convective heat transfer (Nu) marginally improves with the increasing J. Inter-linked micro-channels with counter flow has given improved convective heat transfer but with an increase in frictional factor. The Nu with counter flow is found almost 15% higher than that with parallel flow at Re = 1200. The design can be further explored based on present calculations for a positive addition of designing micro-channel heat sinks.
