Abstract:
A compact back-flow stopper using an elastic flexure mechanism for a cooling fan is shown and described. The backflow stopper assembly comprises a frame configured to structurally support a fin array when coupled to a fan. The fin array comprises a plurality of flexural deformation elements and associated fin elements arrayed in a radial arrangement to establish a pathway for airflow, each of the flexural deformation elements configured to move an attached fin element responsive to airflow impacting the attached fin element. Flex limiter elements are coupled to the frame and configured to limit flexure of the fin elements beyond a predetermined flexure in relation to the frame to stop backflow of air through the fin array. A fan assembly with a backflow stopper is shown and described. Also, a data storage assembly using fan assemblies with backflow stoppers is also shown and described.

Claim (Index 1):
A backflow stopper assembly, comprising:\n a frame configured to structurally support a fin array when coupled to a fan; the fin array comprising a plurality of fin elements arrayed in a radial arrangement to establish a pathway for airflow, each of the fin elements configured to move responsive to airflow impacting the attached fin element; and one or more flex limiter elements coupled to the frame and configured to limit flexure of the fin elements beyond a predetermined flexure in relation to the frame to stop backflow of air through the fin array wherein the fin array is formed from a single piece of flexible material that establishes a default open state of the fin array and a closed state of the fin array when the airflow is in a direction opposite to that provided by the fan.
