Abstract :
In this paper, the cooling performance of water-cooled heat sinks for heat
dissipation from electronic components is investigated numerically. Computational Fluid Dynamics
(CFD) simulations are carried out to study the rectangular and circular cross-sectional shaped heat
sinks.The sectional geometry of channels affects the flow and heat transfer characteristics
of minichannel heat sinks. The three-dimensional governing equations in steady state and laminar flow
are solved using Finite Volume Method (FVM) with the SIMPLE algorithm. The results show that
the numerical simulation is in good agreement with the experimental data. The thermal and
hydrodynamic characteristics of the heat sinks including Nusselt number, friction factor, thermal
resistance and pumping power for various geometries of heat sinks are discussed in details.
The results indicate that the heat sink with rectangular cross-section has a better heat transfer rate
and the circular channel heat sink has the lower pumping power.
