Abstract

Numerical investigation is conducted to study the thermal performance of a double layer microchannel heat sink (DLMCHS) with the feature of interrupted flow in the bottom layer. The bottom layer has two transverse microchambers in which staggered triangular ribs are added to provide flow disruption. The width of the triangular ribs was varied to understand the effects of fluid flow and heat transfer. The thermal performance of the DLMCHS is evaluated relative to the plain non-interrupted DLMCHS using a dimensionless ratios of average Nusselt number. It is found that the heat transfer rate can be increased with the larger width of front triangular ribs as well as larger width of back triangular ribs, potentially yielding up to 41% enhancement relative to the plain non-interrupted MCHS. The results show that the staggered arrangement of triangular ribs in microchamber can be designed to play a role to divert and converge the flow to achieve better mixing in addition to the advantage of higher heat transfer surface area.
