Due to the high performance of electronic components, the heat generated is increasing dramatically and cooling system for such components becomes one of the most important issues to dissipate heat that generated in electronic component. In the present analysis, a microchannel heat sink configuration is simulated by modelling the stacked microchannel heat sinks in macroscopic scale as if it is ...

Energy is one of the primary foundations supporting evolutionary changes. Heat transfer improved by increasing surface area density and/or changing base fluid characteristics. Because its small size and heat properties, nanofluid cooled microchannel sinks (MCHS) have lately become a popular choice for electronics thermal applications. The influence employing nanofluids cooling chip was investig...

Convective heat transfer of MgO-water nanofluid in a microchannel heat sink is experimentally investigated in various concentrations of 0.01, 0.05, 0.1, and 0.6 wt%. The microchannel consisted of 48 parallel rectangular cross section channels with the height of 800 µm, width of 524 µm and length of 52 mm. A well stability duration (ca. 1 month) was resulted by a 180 min ultra-sonication of the ...

Thermal management has become a critical issue for high heat flux electronics and energy systems. Integrated two-phase microchannel liquid-cooling technology has been envisioned as a promising solution, but with great challenges in flow instability. In this work, silicon nanowires were synthesized in situ in parallel silicon microchannel arrays for the first time to suppress the flow instabilit...

An experimental facility is developed to investigate critical heat flux (CHF) of saturated flow boiling of Refrigerant-123 (R-123) in microchannels. Six parallel Microchannels with cross sectional area of 0.2 mm × 0.2 mm are fabricated on a copper block, and a Polyvinyl Chloride (PVC) cover is then placed on top of the copper block to serve as a transparent cover through which flow patterns and...

The flow distribution in a silicon microchannel heat sink was studied using Infrared MicroParticle Image Velocimetry (IR PIV). The microchannel test piece consisted of seventy-six 110 m wide  371 m deep channels etched into a silicon substrate. Inlet and outlet manifolds, also etched into the substrate, were fed by 1.4 mm inner-diameter tubing ports. An image processing algorithm was develo...

With the recent advance in technologies, thermal transport from different electronic and electrical devices is most vital concern. The microchannel heat sink (MCHS) of liquid cooling a useful device to remove over load. Ionanofluid brand new super potential fluid for its ionic conductivity, non-flammability, negligible volatility, high-level stability. In this research, ionanofluid's velocity f...

The present work experimentally investigates the thermal effects of a synthetic jet actuator on the heat transfer performance of single-phase flow confined in a microchannel heat sink. The heat sink consisted of a single rectangular microchannel 500 μm wide, 300 μm deep and 26 mm long. Deionized water was employed as the cooling fluid. A synthetic jet actuator with a 100 μm diameter orifice was...

In this study the performances of various non-circular microchannel heat sinks (normalized with circular shape) have been comparatively analyzed for CuO-water nanofluid and baseline pure water flow. Nusselt number and Poiseuille number for each microchannel and thermo-physical properties of CuO-water nanofluid (viz., thermal conductivity, viscosity, specific heat and density) have been designed...
