Numerical Investigation of Conjugate Heat Transfer in a Computer Chassis

摘要

The present work investigates a numerical simulation of conjugate heat transfer effects inside a computerchassis which is cooled by fans forcing heat convection. The cooling schemes selected for the current studywere three, based on the available commercial applications. The temperature distribution on the heat sourcesand the air pathlines were investigated in order to get a clear picture about which case fully satisfies theoperating conditions. The simulation was conducted by the commercial CFD software (FLUENT). The solutionis based on the Navier-Stokes equations applying into a three dimensional model. The turbulence model usedin this paper was well validated by corresponding experimental data consisting mainly of velocity profilesand temperature distribution provided in the literature review. The study introduced ways that could bebeneficial, when cooling of electronic components is needed. In addition, through CFD process, theproblematic areas are revealed in order to consider improvements.
