In this study, forced cooling of heat sinks mounted on CPU’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.

CFD analyses of heat sinks for CPU cooling Öztürk, Emre; Tarı, İlker; Department of Mechanical Engineering (2004) In this study, forced cooling of heat sinks mounted on CPU̕s 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.

CFD MODELING OF FORCED COOLING OF COMPUTER CHASSIS OZTURK, Emre; Tarı, İlker (2007-12-01) In this study, Computational Fluid Dynamics, which has taken its position in the thermal design of electronic packages, was used in order to draw a CFD road map for forced cooling conjugate heat transfer analyses in heat generating electronic systems. The main sources of error in CM analyses arise from inappropriate numerical models including turbulence models, radiation modeling and discretization schemes, insufficient grid resolution, and lack of convergence. A complete computer chassis model with heat si...
Numerical Investigation on Cooling of Small form Factor Computer Cases ORHAN, OMER EMRE; Tarı, İlker (2008-11-01) In this study, cooling of small form factor computers is numerically investigated. The problem is a conjugate heat transfer problem in which ambient air is the final heat transfer medium. In modeling the problem, heat transfer using heat pipes running from the CPU to the heat exchanger in the back end of the chassis, forced convection inside the chassis, ventilation of the chassis air, conduction paths inside the chassis, and natural convection from the chassis walls to the ambient air are considered. The n...
Modeling of multidimensional heat transfer in a rectangular grooved heat pipe / Odabaşı, Gülnihal; Dursunkaya, Zafer; Department of Mechanical Engineering (2014) Heat pipes are generally preferred for electronics cooling application due to large heat transfer capacity in spite of small size. Micro heat pipes use small channels, whose dimension is on the order of micrometers, to generate necessary capillary action maintaining fluid flow for heat pipe operation. In the present study a flat micro heat pipe with rectangular cross section is analyzed numerically. A simplified axial fluid flow model is utilized to find liquid-vapor interface shape variation along the heat...
Experimental Spray Cooling Studies with FC-72 and FC-84 to Comprehend the Validity of Volumetric Flux Model (VFM) Balıkcı, Çağrı; Tarı, İlker (null; 2017-09-29) Spray cooling for electronics cooling applications offers superior performance due to the atomization and two-phase flow abilities. Need for spray cooling in thermal applications is on the rise due to increasing heat fluxes and demanding reliability specifications. Unfortunately, it is a very laborious task to predict Critical Heat Fluxes (CHF) for spray cooling by means of Computational Fluid Dynamics (CFD). Therefore, thermal engineers generally prefer using empirical correlations to determine capabilitie...
