    Abstract: To provide enhanced operation of data storage devices and systems, various systems, apparatuses, and methods are provided herein. In a first example, a backflow assembly includes a backflow stopper comprising a frame configured to structurally support a fin array when coupled to a fan, the fin array comprising 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. An acoustic barrier assembly is positioned adjacently to the backflow stopper and configured to attenuate acoustic waves emanating from the fan.

    Abstract: Apparatuses and methods are provided for locking an air-moving assembly within a chassis when in operational state. The apparatus includes a locking louver assembly having a louver(s) and locking mechanism. The louver(s) is disposed at an air inlet or outlet of the air-moving assembly, and pivots between operational and quiesced orientations, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The locking mechanism includes a keying element(s) affixed to the louver(s) to pivot therewith, which includes an elongated key(s) oriented in a first direction when the louver(s) is in operational orientation, and a second direction when in quiesced orientation. A key-receiving element(s) is associated with the chassis and includes a key opening(s) which receives and accommodates movement of the elongated key(s) between the first and second directions, and prevents removal of the air-moving assembly from the chassis with the key(s) oriented in the first direction.

    Abstract: A backflow prevention device includes a plurality of flaps that are connected pivotally to a casing of a fan. When a blade unit of the fan rotates to generate an airflow entering the casing via an airflow inlet and exiting the casing via an airflow outlet, the flaps are driven to pivot away from the blade unit to open positions, where the flaps serve as stator blades for the fan. When rotation of the blade unit is stopped, the flaps are driven by a reverse flow directed toward the airflow outlet and the blade unit to pivot toward the blade unit to closed positions, where the flaps close the airflow outlet to prevent air from entering the casing via the airflow outlet.
