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 includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold comprises a inlet header, a outlet header, and a multi-helical core section. The inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed laterally across a plane normal to the first fluid axis. The outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The multi-helical core section fluidly connects the inlet header to the outlet header via a plurality of laterally distributed helical tubes, each helical tube corresponding to one of the plurality of first fluid branches and oriented parallel to all others of the plurality of helical tubes at each axial location along the first fluid axis.

IPC: F16K47/02
Abstract: A check valve has a valve seat defining an aperture and a seating surface. A stop is fixed in position relative to the valve seat and has a solid portion formed as a single homogeneous component. At least one cavity is sealed within the solid portion and is at least partially filed with a particulate material. The solid portion defines a contact surface. A flapper is moveable between a closed position in which the flapper is sealingly engaged with the sealing surface and an open position in which a contact surface of the flapper is in contact with the stop. A method is also disclosed.

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.
