| 20090126909 | SYSTEM AND METHOD FOR FACILITATING COOLING OF A LIQUID-COOLED ELECTRONICS RACK - Systems and methods are provided for cooling an electronics rack, which includes a heat-generating electronics subsystem across which air flows from an air inlet to an air outlet side of the rack. First and second modular cooling units (MCUs) are associated with the rack and configured to provide system coolant to the electronics subsystem for cooling thereof. System coolant supply and return manifolds are in fluid communication with the MCUs for facilitating providing of system coolant to the electronics subsystem, and to an air-to-liquid heat exchanger associated with the rack for cooling air passing through the rack. A controller monitors the system coolant and automatically shuts off flow of system coolant through the heat exchanger, using at least one isolation valve, upon detection of failure at one of the MCUs, while allowing the remaining operational MCU to provide system coolant to the electronics subsystem for liquid cooling thereof. | 05-21-2009 |
| 20090129000 | INTER-RACK AIRFLOW ARRESTING APPARATUS AND METHOD FOR FACILITATING COOLING OF AN ELECTRONICS RACK OF A DATA CENTER - An airflow arrester is provided and configured to reside between electronics racks disposed in a row within a data center. The airflow arrester includes a panel, which when operatively disposed, has a first vertical end, a second vertical end, and a central vertical hinge located intermediate the first and second vertical ends. The airflow arrester further includes an attachment mechanism at the first vertical end and at the second vertical end, and when operatively disposed between a first and second structures, the airflow arrester has a single V-shaped configuration, and is sized and constructed to block airflow from passing therebetween. The single V-shaped configuration provides operational stability to the airflow arrester by translating net twisting forces applied to the airflow arrester to normal forces applied to the first and second structures at the attachment points of the airflow arrester to the first and second structures. | 05-21-2009 |
| 20090129016 | AIRFLOW ARRESTING APPARATUS AND METHOD FOR FACILITATING COOLING OF AN ELECTRONICS RACK OF A DATA CENTER - An airflow arresting apparatus is provided configured to reside above an electronics rack within a data center. The apparatus includes an airflow arrester and a track mechanism. The airflow arrester includes a collapsible panel sized and configured to reside above the electronics rack, and when operatively positioned above the electronics rack, to extend vertically above the electronics rack and at least partially block airflow from passing over the electronics rack between the air outlet and air inlet sides of the rack. The track mechanism is sized and configured to reside above the electronics rack, and the airflow arrester is slidably engaged with the track mechanism. Positioning of the airflow arrester at a desired location above the electronics rack is facilitated by the airflow arrester slidably engaging the track mechanism. | 05-21-2009 |
| 20090255598 | DOUBLE POPPET QUICK CONNECT - Two independent poppets/valves that open and close independently as a quick connect coupling is mated and unmated are employed as part of a cooling system for high end data processing systems. More particularly, the present invention comprises a quick connect poppet valve having two internal, independently functioning sealing seats therein disposed within a serially connected flow path to prevent leakage and to minimize the effects of debris. | 10-15-2009 |
| 20090256351 | Spray Shielding And Thermal Isolation Method And Apparatus For Quick Connects Used In A Computing System Environment - A method and associated apparatus for providing an insulating housing and a protective sleeve for quick connect fittings and couplings of a computer system environment. In one embodiment, the insulative housing has a hollow center to be placed around the couplings and further comprises an insulative sleeve having a plurality of complementary parts that fit together around the coupling as a singular unit and a fastener to open and close the sleeve such that the coupling is at least partially exposed. In an alternate embodiment, a protective sleeve with a hollow center is provided that once disposed around the quick connect fittings will protect against leakage of liquids flowing into quick connect fittings during mating and unmating of them. The sleeve comprises an actuation collar area that extends over unmated portion of the quick connect fitting and a flare area disposed over the actuation collar to provide an additional gripping area for actuating the quick connect fitting. | 10-15-2009 |
