Convective Heat Transfer of Al2O3-water Nanofluids in a Microchannel Heat Sink

Current Nanoscience, 2012
The 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.

Forced convection heat transfer in microchannel heat sinks

International Journal of Heat and Mass Transfer, 2007
Abstract This paper presents an analysis of forced convection heat transfer in microchannel heat sinks for electronic system cooling. In view of the small dimensions of the microstructures, the microchannel is modeled as a fluid-saturated porous medium. Numerical solutions are obtained based on the Forchheimer–Brinkman-extended Darcy equation for the

Cooling Performance of Nanofluids in a Microchannel Heat Sink

ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 1, 2009
This 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, 2009
The 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, 1997
Numerical 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, 2009
A 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 ...
