The main objective of this study is to enhance the thermal efficiency of rectangular Micro-channel heat sink (MCHS) by creating the interruption in the flow path using three identical trapezoidal ribs along the channel length. There was a several, thorough research on heat transfer performance and flow characteristics through Micro-channel heat sink for the different kind of ribs shapes and other parametrical configurations. In this study trapezoidal ribs are aligned from each other at an offset of 2.5mm while taking one rib at the Centre of the channel. The Reynolds number is used within the range of 200-1000, aiming to identify the best operating conditions for maximizing heat transfer efficiency. The study also scrutinized the relationship between fluid flow characteristics, specifically inlet velocities, and resulting heat transfer rates by determining the Nusselt number at various fluid inlet velocities. This indicates that the microchannels with trapezoidal ribs proved more efficient heat transfer enhancement and better thermal performance compared to the previous VR-MC model. The higher Nusselt numbers suggest improved cooling efficiency and enhanced heat transfer in practical applications utilizing microchannels with trapezoidal ribs.
