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 numerical model is analyzed using a commercial finite volume computational fluid dynamics software package. The effects of grid selection, discretization schemes and turbulence model selection on simulation results are discussed. In addition, recirculation and relaminarization are addressed briefly as examples of physical phenomena affecting cooling. For a comparison with the computational fluid dynamics results, an experiment is conducted and some temperature measurements are obtained from critical locations inside the chassis. The computational results were found to be in good agreement with the experimental ones.

Numerical investigation on cooling of small form factor computer cases Orhan, Ömer Emre; Tarı, İlker; Department of Mechanical Engineering (2007) In this study, cooling of small form factor computer is numerically investigated. The numerical model is analyzed using a commercial computational fluid dynamics software Icepak™ . The effects of grid selection, discretization schemes and turbulence models are discussed and presented. In addition, physical phenomena like recirculation and relaminarization are addressed briefly. For a comparison with the computational fluid dynamics results, an experiment is conducted and some temperature measurements are ob...
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...
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...
Passive Cooling Assembly for Flat Panel Displays with Integrated High Power Components Tarı, İlker (2009-08-01) Passive cooling of flat panel display designs with integrated high power components is investigated with the help of recently available semi-emprical and CFD based heat transfer correlations. A heat-spreader-heat-sink assembly is proposed for effective external natural convection cooling of the display panel. A flat vertical surface and plate finned heat sinks with various fin heights are considered as heat sinks in the assembly. Heat dissipation limits for both types of heat sinks are determined for variou...
Heat transfer and pressure drop experiments on CMOS compatible microchannel heat sinks for monolithic chip cooling applications Koyuncuoglu, Aziz; Jafari, Rahim; Okutucu-Ozyurt, Tuba; Külah, Haluk (2012-06-01) Novel CMOS compatible microchannel heat sinks are designed, fabricated and tested for monolithic liquid cooling of integrated circuits. The proposed heat sink is fabricated by low temperature surface micromachining processes and requires no design change of the electronic circuitry underneath, hence, can be produced by adding a few more steps to the standard CMOS fabrication flow. The microchannel heat sinks were tested successfully under various heat flux and coolant flow rate conditions. The cooling tests...
