摘要： An orifice insert is provided and includes a center plug and a ring feature. The center plug has first and second ends and an exterior surface extending between the first and second ends. The exterior surface defines multiple inflow channels that extend from the first end toward the second end and terminate at termination points midway between the first and second ends. The ring feature is disposed about the center plug and the multiple inflow channels to define, with the center plug, a plenum with which the termination points of the multiple inflow channels are fluidly communicative.

摘要： An inclined heat exchanger for use in a motor vehicle. The heat exchanger contains at least two flat tubes and at least two corrugated fins. The flat tubes and the corrugated fins are stacked alternately one above the other in a height direction (HR) to form a stack. The corrugated fins include a rhombic cross-section. A corrugated fin is also provided for use in the heat exchanger, as well as a method for manufacturing the corrugated fin.

摘要： A counter-flow heat exchanger comprising a heat exchanger core including an inner wall and an outer wall radially outward and spaced apart from the inner wall. A first flow path is defined within the inner wall and a second flow path is defined between the inner wall and the outer wall. The heat exchanger core includes a primary flow inlet, a primary flow outlet and a middle portion therebetween. The inner and outer walls are concentric at the primary flow inlet of the heat exchanger core. The inner wall defines a first set of channels extending axially from the primary flow inlet to the middle portion of the heat exchanger core diverging away from a radial center of the heat exchanger core. The inner wall and the outer wall define a second set of channels extending axially from the primary flow inlet to the middle portion of the heat exchanger core converging toward the radial center of the heat exchanger core.

摘要： A cross-flow heat exchanger for gas turbine engines which may be utilized to transfer heat from one fluid flow 46 to a second independent fluid flow wherein one of the fluid flows has a high differential inlet pressure and temperature. The heat exchanger has robust construction to inhibit mixing of the fluid flows during a single burst duct event.

摘要： A double tube includes an inner tube having a corrugated petal shape in a wave form in an outer tube. The double tube is manufactured by a method including: inserting the inner tube into the outer tube and coaxially disposing the inner tube and the outer tube; inserting a plurality of petal forming bars into a space between the outer tube and the inner tube and arranging the petal forming bars along a circumferential direction at predetermined intervals; disposing an assembly of the outer tube, the inner tube, and the petal forming bars in a mold of a hydroforming machine; supplying a fluid in the inner tube while applying a pressure to the inner tube in an axial direction to expand the inner tube; and separating the petal forming bars from the space between the outer tube and the inner tube.

摘要： A counter-flow heat exchanger core includes a first wall defining a longitudinal axis. The first flow path is defined within the first wall. The first flow path includes a primary flow inlet and a primary flow outlet downstream from the primary flow inlet. The heat exchanger core includes at least two hollow vanes circumferentially spaced apart and extending in a radially inward direction from the first wall. Each of the at least two hollow vanes includes a first vane wall and a second vane wall. The heat exchanger core includes a second flow path defined within the at least two hollow vanes between the first vane wall and second vane wall of each of the at least two hollow vanes. The heat exchanger core includes at least one fin extending between two of the at least two circumferentially spaced apart vanes.

摘要： A counter-flow heat exchanger is provided that includes: a first fluid path having a first supply tube connected to a first transition area separating the first fluid path into a first array of first passageways, with the first array of first passageways merging at a first converging area into a first discharge tube; and a second fluid path having a second supply tube connected to a second transition area separating the second fluid path into a second array of second passageways, with the second array of second passageways merge at a second converging area into a second discharge tube. The first passageways and the second passageways have a substantially helical path around the centerline of the counter-flow heat exchanger. Additionally, the first array and the second array are arranged together such that each first passageway is adjacent to at least one second passageway.

摘要： A round metal pipe 1 including a bend portion 10 is configured such that on an axial direction cross-section of the bend portion 10, an outer half portion 11b of a peripheral wall portion 11 of the bend portion 10 has an outwardly projecting, non-circular arc shape in which a central portion in a y direction, which is orthogonal to a bend radius direction x of the bend portion 10, forms an outermost peripheral portion 13, and a distance Lb from respective intermediate portions 15 between the outermost peripheral portion 13 and a pair of proximal end portions 14 of the outer half portion 11b to a pipe center O is shorter than a distance La from the outermost peripheral portion 13 to the pipe center O. Thus, advantages such as suppressing reductions in the sectional area and minimum inside width of the bend portion 10 and reducing flow path resistance can be obtained, and the round metal pipe 1 can be manufactured easily and appropriately.
