摘要： An apparatus for cooling a memory module installed in a computer system includes a liquid coolant conduit that is connected to a conduit support structure having a form factor selectively securable within a first preconfigured memory module socket of the computer system in order to position the liquid coolant conduit above the first socket. A heat pipe provides direct thermal contact between the liquid conduit and a heat spreader assembly in direct thermal contact with a face of the memory module. The apparatus may include a second heat pipe and second heat spreader assembly for similarly cooling a second memory module. In alternative configurations, the apparatus may cool memory modules on opposing sides of the conduit or memory modules that are both on the same side of the conduit.

摘要： Apparatus and method are provided for facilitating cooling of an electronic component. The apparatus includes a liquid-cooled cold plate and a thermal spreader associated with the cold plate. The cold plate includes multiple coolant-carrying channel sections extending within the cold plate, and a thermal conduction surface with a larger surface area than a surface area of the component to be cooled. The thermal spreader includes one or more heat pipes including multiple heat pipe sections. One or more heat pipe sections are partially aligned to a first region of the cold plate, that is, where aligned to the surface to be cooled, and partially aligned to a second region of the cold plate, which is outside the first region. The one or more heat pipes facilitate distribution of heat from the electronic component to coolant-carrying channel sections of the cold plate located in the second region of the cold plate.

摘要： Embodiments of the present invention include computer-implemented methods for selectively applying remedial actions, according to a predefined order, for reducing the error rate in a computer memory system. In one embodiment, an ordered set of remedial actions are sequentially invoked in response to a single-bit error (SBE) in a DIMM reaching successive error thresholds. For example, in an air-cooled system, the remedial actions may include dynamically increasing a DIMM refresh rate, dynamically increasing a rate of airflow used to cool the DIMMs, and dynamically throttling the DIMMs. The remedial actions may be layered as they are successively invoked, to provide a cumulative remedial effect. At least two of the remedial actions may be simultaneously invoked in response to a multi-bit error rate reaching an associated threshold.

摘要： An air moving apparatus comprises an axial fan and an electrostatic device. The axial fan has a rotatable shaft defining a central axis of the axial fan, a plurality of blades secured to the shaft, and an air inlet opening. The electrostatic device is disposed immediately upstream of the air inlet opening of the axial fan, and includes a collector and an emitter. In one embodiment, the electrostatic device comprises a cylindrical collector coupled to ground and has a central axis aligned with the central axis of the axial fan, wherein the cylindrical collector has an inner diameter that is substantially the same as the diameter of an air inlet opening to the axial fan. The electrostatic device further comprises a plurality of emitter wires coupled to a terminal of a direct current source and extending lengthwise within the cylindrical collector. The axial fan moves air longitudinally through an air inlet opening of the axial fan, and, during operation of the axial fan, the application of an electrical potential between an emitter and a collector causes ionic air movement radially outwardly away from a central axis of the axial fan.

摘要： Embodiments of the present invention include a cooling system and method for cooling a computer rack by circulating liquid coolant through different sections of a rack heat exchanger under separately controlled flow and temperature conditions. In a method according to one embodiment, a first liquid coolant is supplied to a first section of an air-to-liquid heat exchanger. A second liquid coolant is supplied to a second section of the air-to-liquid heat exchanger at a different temperature than the first liquid coolant. Airflow is generated through rack-mounted computer components to the first and second sections of the air-to-liquid heat exchanger. The flow rates of the first and second liquid coolants are independently controlled to enforce a target cooling parameter. The independent operation of the first and second fin tube sections allows for the increased use of un-chilled water without sacrificing heat removal objectives.

摘要： A testing system includes a single air collection box and a laminar flow system for obtain an airflow measurement. The single airflow box has air inlet and outlet ports at opposite ends. The laminar flow element has a laminar flow element inlet in fluid communication with the air collection box and a laminar flow element outlet sealed with the air outlet port of the air collection box. A blower in fluid communication with the laminar flow element outlet draws airflow into the air collection box through a unit under test and out of the air collection box through the laminar flow element. A pressure transducer senses the differential air pressure across the laminar flow element and enables a determination of the airflow rate.
