Microchannel Heat Sink with Enhanced Heat Transfer Performance by Laser Process
2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018The heat transfer performance of microchannel heat sink which is fabricated by Nanosecond laser machining (NLM) is investigated. The experiment data suggest that the heat transfer performance of microchannel heat sink (MHS) processed by NLM is superior to that by Deep Reactive Ion Etching (DRIE).

Convective Heat Transfer of Al2O3-water Nanofluids in a Microchannel Heat Sink
Current Nanoscience, 2012The research presents an experimental study on the heat transfer and pressure drop characteristics of Al2O3-water nanofluids flowing through a microchannel heat sink (MCHS). The effects of Reynolds number and particle concentrations on the heat transfer and flow behavior are investigated. Comparison of the heat

Flow Boiling Oscillations in Microchannel Heat Sinks
9th AIAA/ASME Joint Thermophysics and Heat Transfer Conference, 2006*† The following presents flow boiling oscillation characteristics in two silicon microchannel heat sink configurations aimed at micro/nano- spacecraft thermal management. One is a conventional heat sink with 45 parallel channels, whereas the second is similar except with cross-links at 3 locations along the channels.

Cooling Performance of Nanofluids in a Microchannel Heat Sink
ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 1, 2009This paper describes an experimental study on microchannel heat sink performance where ZnO nanoparticle suspended fluids are used as coolant. The microchannel heat sink has 65 parallel microchannels branched out from an inlet reservoir and then collected into an outlet reservoir.

Investigation of Flow Distribution in Microchannels Heat Sinks
Heat Transfer Engineering, 2009The thermal efficiency of microchannel-based heat sinks relies on uniform fluid flow distribution between channels. Maldistribution, whether caused by poor manifold design or blockage of individual microchannels, can lead to hotspots and consequent thermal damage.

Manifold microchannel heat sinks: isothermal analysis
InterSociety Conference on Thermal Phenomena in Electronic Systems, I-THERM V, 1997Numerical analyses of manifold microchannel (MMC) heat sinks were performed. The MMC differs from a traditional microchannel heat sink in that the flow length is greatly reduced to a small fraction of the total length of the heat sink. Alternating inlet and outlet channels guide the coolant to and from the microchannels.

Analysis and optimization of electrokinetic microchannel heat sink
International Journal of Heat and Mass Transfer, 2009A mixed (electroosmotic and pressure-driven) flow microchannel heat sink has been studied and optimized with the help of three-dimensional numerical analysis, surrogate methods, and the multi-objective evolutionary algorithm. Two design variables; the ratio of the microchannel width-to-depth and the ratio of fin width-to-depth of the microchannel are ...
