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.

Performance of a polymeric heat sink with circular microchannels

Applied Thermal Engineering, 2006
Abstract The object of this work is the thermal investigation of a polymeric microchannel heat sink designed for the active cooling of small flat surfaces. Its performance, pressure drop, temperature distribution, and thermal resistance are evaluated.

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

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 ...

On the local thermal equilibrium in microchannel heat sinks

International Journal of Heat and Mass Transfer, 2000
The authors discuss laminar and fully developed (both hydrodynamically and thermally) forced convective flow through a microchannel. Analytical solutions for temperature distribution are obtained using one-equation and two-equation models for heat transfer.

Manifold Microchannel Heat Sinks: Numerical Analysis

Cooling and Thermal Design of Electronic Systems, 1995
Abstract Numerical analyses of fluid flow and heat transfer in manifold microchannels were performed. The manifold microchannel differs from a traditional microchannel in that the flow length is greatly reduced to a small fraction of the total length of the heat sink.
