Characteristics of flow-field inside a production computer chassis
Experimental and numerical techniques were used to quantify the flow field inside a production computer chassis. The flow field was characterized for both original and alternative chassis configuration. The alternative chassis configuration consisted in blocking any possible air vents except for the main and secondary intakes. The smoke-wire flow visualization technique generates fine smoke lines inside the enclosure that follow the airflow created by the fan-induced forced convection heat transfer process. The smoke-wire images were taken at a back, center and front planes within the enclosure. The back plane images suggest that the air enters through the main intake for the alternative configuration, whereas very little flow comes through for the original configuration. The center plane shows very little movement. The front section in the original configuration shows that the flow is being pulled through the main intake. The alternative configuration shows that air is not drawn in through the main intake in this plane. (Abstract shortened by UMI.)^
