ABSTRACT:
Airflow bypass dampers made from a resilient material and systems including the resilient dampers. The dampers are secured in a chassis and extend into a deployed position to obstruct airflow through a component bay of a chassis in the absence of a component, such as a sever blade, within the selected bay. The airflow bypass damper bends into a retracted position in response to installing a component into the bay. It returns to its original shape and position when the component is removed. An air moving device moves air through a component installed in the chassis. A plurality of the resilient airflow bypass dampers may be secured in a plurality of bays of a chassis, each resilient damper moving independently of the others. The resilient material bends without permanent deformation. For example, the resilient material may include, without limitation, natural polymers, synthetic polymers and metals. A preferred damper has a curved cross-sectional shape.
