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.

A cooling module including a first air inlet, a second air inlet, and an air discharge vent, the module having two check valves, each mounted in register with a respective inlet and arranged to allow air to pass towards the inside of the module and to oppose a flow of air in the opposite direction. An electronic unit including such a box.

A system which provides redundant cooling of heat generating components within an electronic system with a single row of fans out the use of counter-rotational fans or multiple rows of fan by displacing failed fans in orthogonal directions. The system includes a fan track that has an orthogonal portion and at least one parallel portion. A failed or failing fan is moved from the orthogonal portion of the fan track to the parallel portion of the fan track. A bank of fans are each upon the orthogonal portion of the track. Each fan in the bank of fans acts upon air to produce an airflow. The bank of fans includes a moved fan at least partially filling a void upon the orthogonal portion of the fan track that is created when the failed or failing fan was moved from the orthogonal portion of the fan track to the parallel portion of the fan track.

An apparatus including a first section having a first plurality of card slots, a second section having a second plurality of card slots, a middle section disposed between the first section and the second section, and a channel structure in the middle section configured to vent air out of the apparatus.

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.

Disclosed is a turbo fan including a rotor housing and a fan blade structure. The fan blade structure is arranged around the rotor housing and fixed to the periphery of the rotor housing and includes multiple spaced fan blades extending in the same direction. A section of the fan blade is an arc and the length of the arc is - of the circumference of a circle in which the arc is located. The turbo fan sets the fan blade with an arc section, and when the turbo fan rotates in the direction corresponding to a recess of the fan blade, the arc structure of the fan blade can push more air to increase air volume.

A fan failure backup apparatus includes a first fan module and a second fan module. When a second control unit of the second fan module realizes that the first fan module is failed through a first control unit of the first fan module, and the second control unit realizes that the second fan module is not failed, the second control unit controls the second fan module to additionally enhance a pressure-flow characteristic of a second fan unit of the second fan module.

An electronics module includes a housing with: (i) a forced convection chamber including an internal forced convection space; and, (ii) a passive chamber including an internal passive space that is separated from the forced convection space. At least one fan is connected to the housing and adapted to induce forced convection airflow in the forced convection space. A heat sink is connected to the housing and includes: (i) a heat input portion exposed to the passive space; and, (ii) a heat output portion exposed to the forced convection space. A circuit board assembly is located in the passive space and includes at least one electronic component that is thermally engaged with the heat input portion of the heat sink. A clamping plate is secured to the heat sink and captures the circuit board to the heat sink. The circuit board is isolated from the fan-induced forced convection airflow.
