Abstract: A core arrangement for a heat exchanger includes a first core layer disposed along a first plane and having an inlet and outlet oriented along a first axis within the first plane and a first core stage disposed in fluid communication between the inlet and the outlet. The first core stage includes a first upstream fluid intersection downstream of and adjacent the inlet and having a first inlet continuation and a first bifurcation. The first core stage further includes a first downstream fluid intersection upstream of and adjacent the outlet and having a first outlet continuation and a first recombination. A plurality of first core tubes fluidly connect the first bifurcation to the first recombination. The first core layer further includes a second core stage disposed in fluid communication between the first inlet continuation and the first outlet continuation. The second core stage includes a second upstream fluid intersection downstream of the first inlet continuation and having a second bifurcation, and a second downstream fluid intersection upstream of the first outlet continuation and having a second recombination. A plurality of independent second core tubes fluidly connect the second bifurcation to the second recombination.

Abstract: A check valve includes a valve seat defining an aperture and a seating surface. A flapper is a single homogeneous component having a contact surface and a filler portion. The flapper is pivotally movable relative to the valve seat between a valve closed position in which the contact surface is sealably engaged to the seating surface thereby occluding flow through the aperture, and a valve open position in which the contact surface is a distance from the seating surface. The filler portion has a plurality of voids such that a density of the flapper is lower than if the voids were not present. A method is also disclosed.

Abstract: A flexible manifold adapted for use on a plate-fin heat exchanger core, the flexible manifold comprising a plurality of individual layers, each individual layer defining a lower floor, an upper floor, and two side walls. Each of the plurality of individual layers is adapted to channel a flow of a medium therethrough, each of the plurality of individual layers includes a plurality of vertical members, each of the plurality of vertical members extends vertically from the lower floor to the upper floor of the respective individual layer, and each of the plurality of vertical members is configured to provide structural support for the respective individual layer. The vertical members can be vertical guide vanes and/or vertical columns having a round and/or hydrofoil cross-sectional shape.

Abstract: A check valve flapper for a check valve is provided and includes a flapper body and a hinge portion extending from the flapper body. The hinge portion includes a lower ear, a middle ear, and an upper ear. The lower ear, the middle ear, and the upper ear each include a hinge pin hole having a hinge pin hole diameter and an ear outer radius. A ratio of the hinge pin hole diameter to the ear outer radius is between 0.83 and 0.91.

Abstract: A monolithic core for a heat exchanger comprises a plurality of three-dimensional unit cells arranged along three orthogonal axes of the core, the three orthogonal axes comprising a first axis, a second axis, and a third axis. Each of the plurality of unit cells has a first dimension comprising an axial extent along the first axis, a second dimension comprising an axial extent along the second axis, and a third dimension comprising an axial extent along the third axis. For at least one unit cell of the plurality of unit cells, the first dimension is not equal to the second dimension.

Abstract: A heat exchanger header for receiving a first fluid includes a tubular primary fluid channel oriented along a first axis and having a first cross-sectional area. A first branched region adjacent to the primary fluid channel fluidly connects to a plurality of tubular secondary fluid channels, each having a second cross-sectional area, and a second branched region adjacent to each of the secondary fluid channels fluidly connects to a plurality of tubular tertiary fluid channels, each having a third cross-sectional area. The second cross-sectional area is greater than the third cross-sectional area.
