Heat Transfer of a Double Layer Microchannel Heat Sink

Applied Mechanics and Materials, 2013
A numerical study is conducted to predict the effects of physical parameters of a double layer microchannel heat sink on heat transfer. The physical parameters investigated are the channel height and channel width for different flow orientation at the upper and lower channels.

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), 2018
The 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, 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

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.

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

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, 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.
