Optimum Design of Microchannel Heat Sinks
Microelectromechanical Systems (MEMS), 1996Abstract Analyses have been performed to obtain momentum and thermal characteristics in microchannel heat sinks. The applicability of existing correlations for friction factor and Nusselt number is investigated. The study revealed that existing correlations based on the analytical results can predict the heat sink performance to within ...

In the last few years high-tendency electronic devices have improved to a larger processing capability with smaller physical dimensions. This fact coupled to traditional cooling mechanisms, are not able to dissipate the high heat fluxes generated by these devices (around 200 W/cm2.) Microchannel heat sinks are the new tendency in heat dissipation. Many

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.

Topology Optimization of Manifold Microchannel Heat Sinks
2020 19th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm), 2020The manifold microchannel (MMC) heat sink has been widely studied for liquid-cooling of power-dense electronic components. Conventionally, thermal-fluid performance of an MMC heat sink is analyzed via unit cell simulations and designed by varying the rectangular fin and channel geometries, namely size optimization.

Metallic Nanoemulsion for Microchannel Heat-Sink
ASME 2016 14th International Conference on Nanochannels, Microchannels, and Minichannels, 2016Galinstan is a eutectic alloy of gallium, indium, and tin, of which thermal conductivity is ∼27 times higher than that of water, while the dynamic viscosity is only twice. Thus, heat transfer coefficient can be remarkably enhanced with a small penalty of pumping power.

Heat transfer optimization based on finned microchannel heat sink
International Journal of Thermal Sciences, 2022Abstract The straight microchannel heat sink is relatively low in heat transfer efficiency due to the influence of the thermal boundary layer, and the thermal requirements of which may fail to be met under high heat flux conditions. In this paper, the fins were introduced to form a secondary channel to optimize the heat dissipation effect of the ...

Microchannel Heat Sinking: Analysis and Optimization
2009The present study reviews numerical optimizations of microchannel heat sink with the help of surrogate analysis. The design variables are decided from geometric and shape parameters that influence the performance of the microchannel heat sink. The basic surrogate models are explored with three-dimensional numerical analysis.

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.

Manifold Microchannel Heat Sinks: Numerical Analysis
Cooling and Thermal Design of Electronic Systems, 1995Abstract 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.

Analysis of flexible microchannel heat sink systems
International Journal of Heat and Mass Transfer, 2005Abstract In this work, single layered (SL) and double layered (DL) flexible microchannel heat sinks are analyzed. The deformation of the supporting seals is related to the average internal pressure by theory of elasticity. It is found that sufficient cooling can be achieved using SL flexible microchannel heat sinks at lower pressure drop values for ...
