Abstract
A vent for a computer enclosure is envisioned. The vent system has a fan, operable to draw a flow of air from within the enclosure and direct it out through an outlet vent disposed in a wall of the enclosure. The outlet vent is made of an outlet path. The outlet path is defined by a first and a second side member. The first and second side members are attached to the enclosure and form an environmental seal. The outlet vent also has an outlet face oriented at a first angle relative to the wall. A plurality of slats are rotatably coupled to the outlet face. The plurality of slats maintain a first position when the fan is not operating. When the fan goes into an operational mode and produces an airflow, the plurality of slats swing radially outward to a second position. The plurality of slats return to the first position when the airflow is not present. The angle of the slats in the first position is nearer to parallel to the first angle than when in the second position.
