Abstract
An air valve may include a sheet on a panel that serves as a portion of one wall of an air-cooled enclosure. The panel has a first aperture, having a first radius. The sheet may be deformable and resilient, and have a conductive film on one surface and a second aperture. A plurality of leaves lie in a plane parallel to the panel and extend inwardly a particular distance from a perimeter define the second aperture. The perimeter has a second radius equal to the first radius. The particular distance is less than the second radius. The leaves may deform in response to airflow. The second aperture has a first diameter and first depth in an un-deformed state, and a second diameter and second depth in a deformed state. The second diameter and second depth are greater than the first diameter and first depth.
