  • Publication number: 20140124168
    Abstract: A cooling system for a high performance computing system includes a closed-loop cooling cell having two compute racks and a cooling tower between the compute racks. Each compute rack includes at least one blade enclosure, and the cooling tower includes at least one water-cooled heat exchanger and one or more blowers configured to draw warm air from a side of the compute racks towards a back, across the water-cooled heat exchanger, and to circulate cooled air to a side of the compute racks towards a front. The cooling cell further includes a housing enclosing the compute racks and the cooling tower to provide a closed-loop air flow within the cooling cell. The cooling system further includes cooling plate(s) configured to be disposed between two computing boards within the computing blade, and a fluid connection coupled to the cooling plate and in fluid communication with the blade enclosure.

  • Patent number: 7466561
    Abstract: The system includes a chassis and a printed circuit board (e.g., a motherboard) that is attached to the chassis. The system further includes an actuator that is slidably engaged with the chassis and a cam plate that is rotatably engaged with the chassis. The actuator engages the cam plate such that maneuvering the actuator rotates the cam plate. The system further includes a blade (e.g., an electronic module) which is slidably engaged with the chassis such that the blade slides in a first direction within the chassis as the blade is inserted into the chassis. The blade is inserted into the chassis until the blade engages the cam plate. The cam plate engages the blade such that rotation of the cam plate causes the blade to continue to move in the first direction and engage the printed circuit board.

  • Patent number: 6672878
    Abstract: A system assembly for a computer includes a motherboard situated on a printed circuit board, and a daughterboard situated on a printed circuit board. In the system assembly the daughterboard is positioned parallel to the motherboard. The daughterboard is connected to the motherboard using a connector system. The connector system has a first portion affixed to either the motherboard or the daughterboard which includes a first capture feature and has an opening therein. A second portion has a second capture feature which mates with the first capture feature. A third portion is attached to the second portion of the connector system. A cam moves the third portion with respect to the second portion. A flexible circuit electrically connects the first end and the second end of the connector system. The flexible circuit is of a length to form a curve when the first end and the second end are connected between the first electrical component and the second electrical component.

  • Patent number: 6483024
    Abstract: A device for reducing electromagnetic interference (EMI) leakage through an opening in a housing. The device accepts a printed circuit board or dummy board. Various openings may be provided in the device. The device includes a faceplate, a gasket having a plurality of fingers, and a supporter. The supporter protects the leading edge of the fingers and augments the forces exerted by the fingers in opposition to the opening in the housing.

  • Patent number: 5131859
    Abstract: A circuit board module for a supercomputer includes quick connections for power, ground, coolant quick connects, and circuit quick connects. The quick connections provide for insertion of modules with substantial savings in time and effort. The electrical power and ground connections and the liquid coolant connections engage and disengage automatically upon insertion and removal of the modules. The circuit quick connects require only insertion of a camming tool for connection and disconnection. The modules require no bolting or unbolting of clamps or hoses for the various connections.
