Abstract:
1. An apparatus for adjusting airflow in an enclosure for an electronic module, comprising: a frame having an airflow opening configured to direct airflow in an airflow direction; a gate positioned within the airflow opening and pivotable about a first axis parallel to a top edge of the frame, the gate including side pins positioned within ramps of the frame; a pinion coupled to the gate and rotatable about a second axis, the second axis being perpendicular to the airflow direction and the first axis; and an actuator having an actuator plate slidable with respect to the frame in the airflow direction and defining a contact surface configured to engage the electronic module and be pushed towards the frame in the airflow direction, the actuator supported on the top edge of the frame and comprising a rack meshed with the pinion such that movement of the actuator causes the side pins of the gate to travel along the ramps and the gate to pivot about the first axis coaxial with the side pins of the gate between open and closed positions, wherein the open and closed positions allow, respectively, maximum and minimum airflow through the airflow opening.
