Abstract: A flexible manifold adapted for use on a plate-fin heat exchanger core, the flexible manifold including a plurality of individual layers configured to be metallurgically joined to respective ones of a plurality of layers of the plate-fin heat exchanger core, and further including a first end with at least one port adapted to receive or discharge a medium, a second end distal from the first end, adapted to transfer the medium to or from the plurality of individual layers, a plurality of horizontal guide vanes defining the plurality of individual layers, and a plurality vertical members positioned within each of the individual layers. The flexible manifold is configured to be mechanically and thermally compliant, and can be metallurgically joined to the heat exchanger core by brazing or welding.

Abstract: A heat exchanger is provided. The heat exchanger includes a core that receives a plurality of mediums. The heat exchanger includes a manifold. The manifold includes a first end that receives a first medium of the plurality of mediums. The manifold includes a second end that intersects the core at a manifold/core interface. The manifold includes a plurality of individual layers that provide gradual transitions for the first medium from the first end to the second end to reduce or eliminate discontinuities at the manifold/core interface that cause stress to the heat exchanger.

Abstract: A heat exchanger core consists of first and second fluid channels, each configured to direct flow of respective fluids through the heat exchanger core. Each first fluid channel includes first fluid flow assemblies having inner channels formed by inner channel walls that contain the first fluid, each inner channel surrounded by a barrier channel having a barrier channel wall that isolates the barrier channel from the second fluid. One or more barrier channel vanes support the inner channel within the barrier channel. Each barrier channel provides a void space between the inner channel wall and the barrier channel wall, thereby fluidly separating the first fluid from the second fluid. Each barrier channel can receive the first or second fluid in the event of a breach of the inner channel wall or the barrier channel wall, thereby preventing intra-fluid contamination.

Abstract: A heat exchanger includes a stack of flow conduits. Each flow conduit is configured to conduct a fluid. Parting sheets separate adjacent flow conduits in the stack, providing heat transfer between them. Each of the flow conduits includes vanes extending along a vane path and between top and bottom parting sheets. The vanes are separated from one another, thereby creating flow channels. Each flow conduit also includes a plurality of flow modifiers, each adjacent to a corresponding leading edge of a corresponding vane, so as to cause a disrupted portion of a fluid flow to be incident upon the corresponding leading edge. Each of the flow modifiers includes an aerodynamic portion and a gap portion. The aerodynamic portion extends from at least one of the top and bottom parting sheets. The aerodynamic portion does not connect the top and bottom parting sheets due to the gap portion.

Abstract: An additively manufactured heat exchanger configured to transfer heat between a first fluid and a second fluid includes a first channel with a first wall configured to port flow of a first fluid and a second channel with a second wall configured to port flow of a second fluid. The heat exchanger also includes a barrier channel containing unprocessed build powder provided by the additive manufacturing process and is located between the first wall and the second wall. The barrier channel is configured to prevent mixing of the first fluid and the second fluid when one of the first wall and the second wall ruptures.

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.
