Numerical Studies on the Electronic Gadgets in a Personal Computer Using CFD

The energy conservation of electronic components in computers is a very popular area of research for engineers because the temperature control inside the system unit of a desktop computer plays a vital role in its life and energy consumption. It is essential to study the various factors such as velocity of the inlet air, external temperature, heat generated in various components, heat transfer coefficient at various surfaces and orientation of components to overcome the design issues. In this paper, the three dimensional model of the system unit (SU) has been considered, and the temperature and velocity distribution inside the system unit, for the various operating conditions, have been analyzed using a CFD code ANYSYS-FLUENT 13. An experimental investigation has been carried out to validate the numerical approach.
