In this study, forced cooling of heat sinks mounted on CPU&rsquo / s was investigated.
Heat sink effectiveness, effect of turbulence models, effect of radiation heat
transfer and different heat sink geometries were numerically analyzed by
commercially available computational fluid dynamics softwares Icepak and
Fluent. The numerical results were compared with the experimental data and
they were in good agreement. Conjugate heat transfer is simulated for all the
electronic cards and packages by solving Navier-Stokes equations. Grid
independent, well converged and well posed models were run and the results
were compared. The best heat sink geometry is selected and it is modified in
order to have lower maximum temperature distribution in the heat sink.
