  • Patent number: 7646603
    Abstract: A noise-reducing attachment apparatus for a heat exchanger door is provided for facilitating attenuation of noise emanating from an electronics rack. The apparatus includes a frame structure configured to coupled to the heat exchanger door. The door includes in air opening and air-to-liquid heat exchanger, and air passing through the air opening also passes across the heat exchanger. The air opening facilitates passage of external air through the electronics rack. The frame structure defines in part an airflow channel through the apparatus, wherein air passing through the air opening also passes through the airflow channel when the apparatus is operatively coupled to the door. An acoustically absorptive material, which is coupled to the frame structure and at least partially defines the airflow opening through the apparatus, is selected and positioned to attenuate noise emanating from the electronics rack when the apparatus is coupled to the heat exchanger door.

  • Publication number: 20090323281
    Abstract: Controlling an airflow passing into an electronic component cabinet includes passing an airflow into the electronic component cabinet through a first passage having a first filter, sensing a parameter of the airflow passing through the first passage, detecting a change in the parameter of the first airflow associated with a flow restriction at the first filter, and shifting a first flap from a first position allowing the airflow to pass unrestricted through the first passage, to a second position, wherein the first flap creates a flow restriction for the airflow passing though the first passage, and triggers an actuation mechanism based on the change in parameter of the first airflow. Controlling the airflow further includes opening a second flap that exposes a second passage having a second filter based on the triggering of the switch, and passing an airflow into the electronic component cabinet through the second passage.

  • Publication number: 20090290305
    Abstract: An entrainment heatsink system and method using distributed micro jets. Such a system and/or method utilize a pressurized primary flow through arrays of micro nozzles to entrain a much larger secondary flow to carry heat away from the heatsink. The bleed air from an aircraft engine represents an ideal pressurized air source for the primary flow with respect to such a heatsink. As such, the needed high-pressure primary flow is very small and can be delivered via thin air hoses, which has the flexibility to reach constraint spaces. In addition to the entrainment effect, the distributed micro jets also induce a high level of turbulence in the heatsink, significantly enhancing heat transfer and cooling performance.

    Abstract: A notebook computer with a tilting keyboard, which opens a vent when tilted, solves multiple problems and may further materially contribute to countering terrorism. A tilted position of the keyboard allows the vent to open when the notebook lid is open, thereby providing extra cooling capacity during periods of computer use when there is a lessened need for compactness. The vent is it least partially closed when the keyboard is in the stowed position and the lid is closed, thereby reducing the possibility of debris ingestion when air flow needs are reduced and the need for compactness is increased. A security inspection position of the keyboard enables inspection of the inside of the computer, for example as part of a security checkpoint procedure. A negative tilt can reduce wrist strain and repetitive motion injuries for some users. Some embodiments tilt the keyboard automatically in response to the lid opening, and stow the keyboard automatically in response to the lid being closed.

  • Publication number: 20090016016
    Abstract: A chassis and rack system is disclosed in which a chassis separated into two separate enclosures by a central partition. Each of the enclosures is sized to receive a computer system. The partition includes a pair of vertically oriented vents, with each of the vents in fluid communication with one of the enclosures and the computer system contained therein. Heated air is removed from each computer system through the vent in the partition that is associated with the computer system. Multiple chassis may be placed one atop another in a vertical configuration in which each chassis is either directly above or directly below another chassis. In this vertical configuration, the vents form a vertically oriented common plenum that can be used to evacuate air from multiple chassis arranged in a rack.

  • Publication number: 20080316702
    Abstract: An adjustable filler panel assembly, configured for use in an electronic equipment enclosure, includes a first panel and a second panel, each adapted to block airflow. The first panel has pairs of horizontally aligned adjustment openings formed therein, and the second panel has a pair of horizontally aligned attachment members disposed near one end. The first and second panels are connected to one another in an overlapping arrangement to form an air-blocking panel assembly with the attachment members of the second panel being aligned with and connected to a pair of adjustment openings of the first panel. In addition, the first panel and the second panel are telescopically adjustable relative to one another such that a length of the air-blocking panel assembly is selectively adjustable to fill at least a portion of an opening in the electronic equipment enclosure, thereby blocking air from flowing through the opening.

  • Publication number: 20080300725
    Abstract: Systems and methods for detecting and analyzing elevated temperatures at a component rack to identify and characterize air recirculation anomalies. In one embodiment, temperatures are sensed in proximity to an air intake of the component rack. Temperature sensors communicate with a workstation having system management software including a thermal management component for analyzing air intake temperatures. Predefined temperature differentials (PTD) are established, corresponding to expected temperature differentials between the selected locations in the absence of any appreciable recirculation. The PTD provides a threshold for comparing with “actual” temperature differentials (ATD) to identify the presence and/or mode of recirculation. If an ATD exceeds a corresponding PTD for a predefined time interval, a signal is output. The mode of recirculation, such as left-side, right-side, or dual-surface recirculation, may be determined using as few as four temperature sensors positioned at a zone of interest (ZOI).

  • Patent number: 7457113
    Abstract: A heat extraction system is provided for a laptop computer that comprises a system unit that includes a set of heat sources and a video display unit that is movably attached to the system unit. The laptop computer has air inlets and air outlets that allow air to flow into the system unit, over the heat sources forming heated air, and exhaust the heated air. The laptop computer has a set of tubes, which have an inlet and an outlet, located behind a video display in the video display unit and an air connection from the air outlets to each inlet in the tubes. The set of tubes are formed such that heated air passing through a constriction in the set of tubes changes in velocity and pressure in order to satisfy the conservation of flow rate. Thus, heat produced by the heat sources is extracted from the laptop computer.
