Abstract:
A component-level cooling system for cooling components in a chassis includes a fan in a housing positioned on a circuit board. The housing has a fan inlet on a side, a first fan outlet on one end and a second fan outlet on a second end opposite the first end. The first fan outlet may direct a first airflow in a first direction to a vent on a first panel of the chassis. The second fan outlet may direct a second airflow in a second direction opposite the first direction. A duct comprises a duct inlet for receiving the second airflow, an elbow for redirecting the second airflow in a third direction to avoid the second airflow from colliding with a main airflow to reduce acoustic noise, and a duct outlet located to avoid heated air exiting the duct from re-entering the fan inlet.
