  • Patent number: 11071229
    Abstract: An air shroud includes a main portion, an extension portion, and a first adjustable air baffle. The main portion is in physical communication with one or more cooling fans of an information handling system. The extension portion extends from the main portion. The first adjustable air baffle is in physical communication with the extension portion. The first adjustable air baffle is biased toward an extended position. When a first memory module is located within a first memory slot of an information handling system while the main portion is in physical communication with the one or more cooling fans, the first adjustable air baffle transitions from the extended position to a collapsed position in response to a force being exerted on the first adjustable air baffle by the first memory module.

  • Patent number: 9777736
    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.
