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...

Experiments were conducted to investigate flow boiling heat transfer to a dielectric fluid in a silicon chip-integrated microchannel heat sink. Twenty-four microchannels, each 389 m  389 m in crosssection, were fabricated into the 12.7 mm  12.7 mm silicon substrate. High-speed visualizations (at 12,500 frames per second) were performed simultaneously with heat transfer and pressure drop mea...

The effect of flow instabilities on flow boiling heat transfer in microchannels is investigated using water as the working fluid. The experimental test section has six parallel rectangular microchannels with each having a cross sectional area of 1054 × 197 microns. Flow restrictors are introduced at the inlet of each microchannel to stabilize the flow boiling process and avoid the backflow phen...

Jet impingement two-phase cooling is often used to handle the high heat fluxes of high-performance electronics. While much literature focuses on thermal–hydraulic performance, effects fin geometry transfer and pressure drop have not been thoroughly investigated. This study was undertaken examine those factors more closely. The performance a sink studied for three different configurations: micro...
