    摘要: Some engine applications place spatial constraints on heat exchangers, such as oil coolers. In such a case, a heat exchanger having an oblong rather than a circular cross section can satisfy spatial constraints, and with certain internal geometry, may permit improved heat rejection performance while potentially enabling a cost reduction through a reduction in materials. The heat exchanger has a housing which defines a heat exchanging cavity within which a tube bundle is positioned. The tube bundle is made up of a plurality of tubes in a hexagonal packing pattern that are supported by a plurality of baffles. The tube bundle and the housing define a serpentine flow path between an inlet and an outlet. The serpentine flow path includes a plurality of segments that are generally perpendicular to the tubes, and these segments are separated by flow direction changing windows. The tube bundle has a gap distance at the windows that is relatively large, and a gap distance away from the windows that is relatively small. In addition, each of the tubes of the tube bundle is adjacent to at least three other tubes, such that the perimeter set of tubes creates a hexagonal shape.

    摘要: A wellhead housing has a telescoping casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing. The transfer of casing and pressure loads occurs even in conditions where the telescoping casing hanger may be set in a high position in the wellhead housing on a load shoulder. The transfer of casing and pressure loads also occurs in conditions where the telescoping casing hanger may be set in an earlier installed casing hanger in the wellhead housing for a larger diameter casing string.

    摘要: Disclosed herein is an aerogenerator having a rotation support unit for facilitating rotation of a rotational body. The aerogenerator includes a support pillar, a rotational body, vanes, a rotating force transmission unit, a generating unit and a rotation support unit. The support pillar has a hollow space therein and has a support extension on the upper end thereof. The rotational body is provided on the upper end of the support pillar so as to be rotatable using the rotation support unit. The vanes are provided on opposite ends of the rotational body. The rotating force transmission unit transmits rotating force of the vanes to the generating unit. In the present invention, the rotation support unit comprises a rotating plate which is provided between the rotational body and the support pillar, and first rollers which are provided in the rotating plate and are in contact with the rotational body and the support extension. The rotation support unit further comprises second rollers which are provided under the rotating plate and are in contact with the inner surface of the hollow space of the support pillar. Therefore, the rotational body can easily rotate on the upper end of the support pillar by the first rollers, and the rotational plate can be prevented from being separated from the upper end of the support pillar by the second rollers.

    摘要: A device and a method for creating and/or maintaining an obstruction free upper airway. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.
