    摘要: The invention refers to a component defining a blade or a vane for a rotary machine having a rotor rotatable about an axis. The component includes an inner space forming a passage for a cooling fluid between first and second walls. First ribs project from the fist wall and extend essentially in parallel to each other to form fist channels for the fluid from a leading part of the inner space to a trailing part of the space. The first ribs extend in a first direction forming a first angle of inclination to the axis in the leading part and in a second direction forming a second angle of inclination to the axis in the trailing part. The first angle is greater than the second angle.

    摘要: A method for transpiration cooling of the flow path surface region of an engine component used in a gas turbine engine by channeling a substrate to provide cooling channels through the substrate having a diameter of about 0.005″ to about 0.02″ to allow passage of cooling fluid from a cooling fluid source through the cooling channels. A bond coat of about 0.0005″ to about 0.005″ in thickness is applied to the substrate such that the bond coat partially fills the cooling channels. A porous TBC of at least about 0.003″ to about 0.01″ thick is applied over the bond coat, such that the TBC completely fills the cooling channels. Cooling fluid from a cooling fluid source is passed through the cooling channels and porous TBC. Because the channel exit is filled with TBC, the cooling fluid is transmitted through the porous passageways of the TBC. The porous passageways provide a plurality of tortuous routes to the TBC surface. The present invention further comprises both the cooled flow path surface region formed by the foregoing methods and the turbine component having a porous TBC cooling system connected to a cooling fluid source for cooling the component.

    摘要: A fan drive assembly including a cooling fan (11) and a fluid coupling device (13). The cooling fan includes a fan hub (17), a spider (15), and a plurality of fan blades (19). The coupling device has an output coupling assembly (21) including a body (23) and a cover (25). The body (23) includes preferably only three mounting portions (67), each being disposed immediately adjacent an outer periphery of the body. Each of the mounting portions (67) defines the necessary machining chucking surfaces (73), and a spider mounting surface (75) including a pilot surface (77) engaging the pilot diameter (79) of the spider (15). The body (23) includes cooling fins (61) covering substantially all of the rearward surface (59) of the body not covered by the mounting portions. The fan hub (17) also includes a rearwardly extending air dam portion (81), limiting localized radial air flow. The fan drive is able to improve the radial air flow through the body cooling fins and achieve subatantially greater heat dissipation from the fan drive assembly, thus permitting greater fan speed for a given input speed.

    摘要: A turbocharger including center housing with a thermally decoupling flange is provided. The flange, which extends generally radially outward from a body of the center housing, has a connection portion that can be used to mount the center housing to a turbine housing of the turbocharger. A curved portion of the flange is disposed between the connection portion and the housing body and provides a thermal decouple for reducing the thermal gradient in the connection portion. The curved portion can also increase the flexibility of the flange to reduce the stresses therein that result from temperature variations in the center housing.

    摘要: A blower for flowing cooling air toward a corrugated fin is disposed to face the corrugated fin. The blower is covered with a blower case. Leg portions are integrally formed with and protrude from the blower case to face the corrugated fin at both sides in a corrugated direction of the corrugated fin. The blower case is fixed to a radiation plate by elastic deformation of the leg portions. The leg portions cover the both sides in the corrugated direction of the corrugated fin, so that the corrugated fin is protected from external force.
