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.
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.
摘要:
An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension. Each tier is a 1U modular computer system having a computer chassis configured for mounting in the multi-tiered support, and computer components that need cooling within the computer chassis. An evaporator is in thermal communication with at least one of the computer components, and vaporizes a coolant to cool that component. A condenser dissipates heat from the coolant vapor, and provides liquid coolant back to the evaporator. The condenser directs liquid coolant gravitationally downward, making the condenser and evaporator gravity driven. An air mover within the chassis cools the condenser, blows air across other components needing cooling, and removes heated air from the chassis.
摘要:
A bulkhead plate member for providing an attenuating barrier for electromagnetic interference (EMI) noise in a computer system housing. The bulkhead plate member includes a rectangular shaped main portion having a material thickness. The main portion has a plurality of edge walls defining an opening for receiving a peripheral component connector affixed to a printed circuit board (PCB). The edge walls are adapted to contact side walls of the peripheral component connector to provide contact regions substantially perpendicular to the main portion and greater than the material thickness of the main portion, such that EMI noise is conducted through the bulkhead plate member, at the edge walls of the opening, to a bulkhead wall of the computer system housing thereby suppressing the EMI noise. The edge walls of the opening provides increased surface area contact between the bulkhead plate member and the peripheral component connector to maximize the attenuation of EMI noise around the connector.

A liquid loop cooling system, a tubing encloses an interior lumen within which a cooling fluid can circulate. A plurality of heat exchangers is coupled to the tubing and is configured within in a constrained space in conformance to space availability.
摘要:
An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension. Each tier is a 1U modular computer system having a computer chassis configured for mounting in the multi-tiered support, and computer components that need cooling within the computer chassis. A cold plate is in thermal communication with at least one of the computer components, and convectively removes heat from that component using a liquid coolant. A heat exchanger dissipates heat from the liquid coolant, and provides liquid coolant back to the cold plate. An air mover within the chassis cools the heat exchanger, blows air across other components needing cooling, and removes heated air from the chassis. The air mover may extend substantially across the chassis, or it may blow crosswise from an outlet-ventilating direction.

In a liquid loop cooling device, a heat exchanger includes a tube arranged in a multiple-pass configuration including a plurality of substantially parallel tube segments. The heat exchanger further includes a plurality of fins coupled to the tube segments. The fins for adjacent tube segments are separated by a gap.

An information technology (IT) equipment positioning system comprises a plurality of wireless transponders distributed in multiple locations in the data center and a controller. The controller is adapted to operate the transponders using triangulation to identify and detect positioning according to three-dimensional coordinates for wireless-tagged IT equipment located in the data center.
