Microchannel heat sinks are an efficient cooling method for semiconductor packages. However, to properly cool increasingly complex and thermally dense circuits, microchannel designs should be improved expanded on. In this paper, with secondary channels ribs investigated using computational fluid dynamics coupled a multi-objective optimization algorithm determine propose optimal solutions based ...

The present study investigates the thermo-hydraulic characteristics of a microchannel sink with novel trefoil Shaped ribs. motivation for this form rib shape is taken from design lung alveoli that exchange oxygen and carbon dioxide. This has been conducted numerically by using code commercially available Fluent software. shaped ribs were mounted on centerline different walls in three configurat...

This work explains the simulation-based study to understand thermohydraulic characteristics (thermal resistance and pumping power) of a MEMS heat sink using serpentine microchannels employed for thermal management concentrated photovoltaic cells; planar dimensions both are 1 cm by cm. In this study, water is coolant constructed in silicon. Over Reynolds number varying from 50 1000 concentration...
