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.

Heat transfer performance study of microchannel heat sink with composite secondary channels

International Communications in Heat and Mass Transfer, 2023
To enhance the performance of microchannel heat sinks, secondary channels or ribs are oftenused separately. However, the synergistic enhancement of heat dissipation by secondary channels and individually composite with different types of ribs and the ...

THERMAL PERFORMANCES OF CROSS-FLOW MICROCHANNEL HEAT SINKS

Proceeding of Proceedings of CHT-21 ICHMT International Symposium on Advances in Computational Heat Transfer, 2021
A numerical investigation is carried out that show how reasonably good thermal performances can be obtained with cross-flow microchannel heat sinks provided that an unequal number of microchannels is used in the two layers and a non-uniform microchannel inlet velocity distribution is produced by properly designed headers.

Comparison Between Traditional Microchannels Heat Sinks and Microchannels Heat Sinks Based on Biomimical Tendencies

Volume 4: Fatigue and Fracture; Fluids Engineering; Heat Transfer; Mechatronics; Micro and Nano Technology; Optical Engineering; Robotics; Systems Engineering; Industrial Applications, 2008
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

Flow Boiling in a Microchannel Heat Sink

Heat Transfer, Part A, 2005
Flow boiling heat transfer in a microchannel heat sink is experimentally investigated. The microchannels considered are 275 μm wide and 636 μm deep, and the experiments are conducted at inlet water temperatures in the range of 66 to 95°C and mass fluxes of 341 to 936 kg/m2s.

Heat sink optimization with application to microchannels

IEEE Transactions on Components, Hybrids, and Manufacturing Technology, 1992
The equations governing the fluid dynamics and combined conduction/convection heat transfer in a heat sink are presented in dimensionless form for both laminar and turbulent flow. A scheme presented for solving these equations permits the determination of heat sink dimensions that display the lowest thermal resistance between the hottest portion of the

Optimum Design of Microchannel Heat Sinks

Microelectromechanical Systems (MEMS), 1996
Abstract 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 ...
