摘要:
An airflow control apparatus includes a controllable airflow resistance aligned with an airflow path of a plurality of airflow paths, a sensor capable of detecting an airflow condition in at least one of the plurality of airflow paths, and a controller. The controller is coupled to the controllable airflow resistance and to the sensor, and can control the controllable airflow resistance to manage airflow recirculation based on the airflow condition detected by the sensor.

A printed circuit board connector engagement apparatus includes a four-bar linkage capable of coupling to an electronics system housing and is configured to accept and enable a printed circuit board to travel in a first direction until a connector on the printed circuit board and a corresponding connector coupled to the housing are aligned. The four-bar linkage further enables the printed circuit board to travel essentially orthogonal to the first direction to engage the printed circuit board and housing connectors.

A fan rotor system for cooling an electronic system includes a rotor body configured to be rotated by a fan motor and at least one collapsible fan blade mounted on the rotor body for moving cooling air through the electronic system. The at least one collapsible fan blade has a first air driving position, wherein the fan blade moves cooling air in a desired direction for cooling the electronic system, and a second air passage position, wherein the at least one collapsible fan blade is collapsed to allow cooling air to pass the at least one collapsible fan blade with less drag than when the at least one collapsible fan blade is in the first air driving position. The at least one collapsible fan blade is movable between the first air driving position when the rotor body is rotating and the second air passage position when the rotor body is not rotating.
摘要:
A mechanism for use in insertion and extraction of a first printed circuit board (PCB) to and from a second PCB so as to engage and disengage an electrical connector of the first PCB to and from a corresponding electrical connector of the second PCB. The insertion and extraction mechanism includes a stiffener bar and a mounting block. The stiffener bar is affixed to the first PCB immediately adjacent to the electrical connector for stiffening the first PCB in the vicinity of the electrical connector. The mounting block is affixed to the second PCB immediately adjacent to the corresponding electrical connector. A threaded fastener is carried by the stiffener bar and is engageable with the mounting block. Rotation of the fastener in a first direction causes the first PCB to be inserted to the second PCB which causes the electrical connector to be engaged with the corresponding electrical connector. Rotation of the fastener in a second direction causes the first PCB to be extracted from the second PCB which causes the electrical connector to be disengaged from the corresponding electrical connector. An alignment pin of the stiffener bar is engageable with an alignment opening in the mounting block to insure that the electrical connector and the corresponding electrical connector are properly aligned during insertion and extraction of the first PCB to and from the second PCB.

An airflow management apparatus is used in an electronic system and includes a flexible air baffle that mounts on a chassis of an electronic device in an arrangement and obstructs air flow between an air inlet vent and an air exhaust vent of the electronic device. The flexible air baffle has a thickness that extends across a gap to contact an adjacent vertically-stacked electronic device.
