Dual Redundant Cooling System For A Container
A dual redundant cooling system for a container is provided. The dual redundant cooling system includes a first cooling unit and a second cooling unit. The first cooling unit is positioned in a first cabinet attached to the container. The first cooling unit includes a first controller operating a first cooling loop to cool an interior of the container. The second cooling unit is positioned in a second cabinet attached to the container and adjacent the first cabinet. The second cooling unit includes a second controller operating a second cooling loop to cool the interior of the container. The first cooling unit and the first cooling loop are separate from the second cooling unit and the second cooling loop. The first controller and the second controller communicate a switch signal between each other so that either the first cooling unit is a primary cooling unit operating the first cooling loop or the second cooling unit is the primary cooling unit operating the second cooling loop. The switch signal switching the primary cooling unit.
FAN FAILURE COMPENSATION
A system of fans ventilates heated air from within an IHS (Information Handling System), such as a rack-mounted server, when operated during normal conditions at a rated fan speed. A controller detects a failure of a fan of this fan system and identifies the functioning fans of the system. One or more of the functioning fans are selected for boosting by operation of a fan failure compensation circuit that has been configured for delivery of additional power to the selected boost fans. The fan failure compensation circuit delivers an output voltage that boost the airflow output of the system to compensate for the failed fan. By increasing the output voltage by approximately twenty percent, the boosted fans operate at approximately fifteen percent above rated speeds, which has been demonstrated to compensate for a failed fan while avoiding further failures during the expected lifespan of the fan system.
Implementing electronic enclosure cooling containment for concurrent maintenance actions
Methods and structures are provided for implementing electronic enclosure cooling containment for concurrent maintenance actions with a top cover of the electronic enclosure removed. The structure includes a moveable airflow baffle being attached to the associated electronic enclosure. During concurrent maintenance actions, the moveable airflow baffle is moved to an open position over at least a partial length of a replaceable component, without being detached or removed from the associated electronic enclosure. During normal operations, the moveable airflow baffle hangs down over at least a partial length of a replaceable component.

COVER FOR SOCKET OF FAN WALL
A cover for covering an opening of a socket formed by a housing comprises a body; one or more bosses extending from the body, a first locking mechanism, a second locking mechanism, and a release tab. The bosses movably couple the body to the housing such that the body is movable between first and second positions. The first locking mechanism releasably attaches to the housing to secure the body in the first position. The second locking mechanism releasably attaches to the housing to secure the body in the second position. The release tab aids in detaching the first locking mechanism from the first wall and the second locking mechanism from the second wall. When the body is in the first position, the body allows access to the socket through the opening. When the body is in the second position, the body prevents access to the socket through the opening.

ESTIMATING THE REMAINING USEFUL LIFE FOR COOLING FANS BASED ON A WEAR-OUT INDEX ANALYSIS
The disclosed embodiments provide a system that estimates a remaining useful life (RUL) for a fan. During operation, the system receives telemetry data associated with the fan during operation of the critical asset, wherein the telemetry data includes a fan-speed signal. Next, the system uses the telemetry data to construct a historical fan-speed profile, which indicates a cumulative time that the fan has operated in specific ranges of fan speeds. The system then computes an RUL for the fan based on the historical fan-speed profile and empirical time-to-failure (TTF) data, which indicates a TTF for the same type of fan as a function of fan speed. Finally, when the RUL falls below a threshold, the system generates a notification indicating that the fan needs to be replaced.
CONTROLLER WITH FAN MONITORING AND CONTROL
An industrial automation controller includes a housing with a forced convection chamber. First and second fans are releasably connected to the housing and are adapted to induce airflow through the forced convection chamber. The first and second fans are each connected to the housing by respective first and second latch systems that each include a primary latch and a secondary latch. The secondary latch imposes a time delay during removal and replacement of a fan to facilitate hot swapping of the fan with a replacement fan. A make-last/break-first contact system is provided for each fan such that the fan is shutdown in a controlled manner prior to removal of the fan from the housing. The controller monitors internal temperature and fan speed. The controller initiates, logs, and reports fault conditions based upon the monitored temperature and/or fan speed. The controller is shut down if the monitored temperature exceeds a select temperature level.

Electronic device
An electronic device includes a main body, a case, and an airbag. The main body includes an accommodation space and an opening, and a fan is disposed in the accommodation space. The case is disposed on the opening and one side of the case is connected to one side wall of the main body surrounding the opening. The airbag is disposed in the accommodation space below the orthographic projection of the case and communicates with the fan. When the airbag is not yet inflated, the case horizontally covers the opening. When the fan rotates at a speed greater than a critical speed, the airbag is inflated by the fan to lift another side of the case, so that the case is tilted on the main body to expose the opening.
