摘要： 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.

摘要： A closure bar adapted for use in a heat exchanger core includes a center void region configured to be partially filled with a phase-changing material and sealed, thereby containing the phase-changing material. The phase-changing material is configured to change phase in a forward direction as the flow of hot fluid over the closure bar begins, thereby slowing a rate of a temperature increase by absorbing a latent heat as the phase-changing material changes phase in the forward direction, and change phase in a reverse direction as the flow of hot fluid over the closure bar ceases, thereby slowing a rate of a temperature decrease by liberating the latent heat as the phase-changing material changes phase in the reverse direction. A method of producing and using the closure bar is also disclosed.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A heat exchanger includes a core section defining a plurality of first fluid channels and a plurality of second fluid channels. The heat exchanger also includes a header section defining a plurality of first fluid layers and a plurality of second fluid layers. The heat exchanger further includes a transition region located between the header section and the core section, the transition region fluidly coupling the plurality of first fluid layers to the first fluid channels, each of the first fluid layers routing a first fluid to a respective group of first fluid channels.

摘要： A counter-flow heat exchanger including: a primary flow passageway comprising a primary flow inlet, a primary flow outlet, and a plurality of primary flow subset passageways therebetween; a secondary flow passageway comprising a secondary flow inlet, a secondary flow outlet, and a plurality of secondary flow subset passageways therebetween; and a heat exchanger core comprising portions of the plurality of primary flow subset passageways and the plurality of secondary flow subset passageways, the secondary flow passageway being in thermal communication with the primary flow passageway in the heat exchanger core, wherein the primary flow subset passageways in the heat exchanger core and the secondary flow subset passageways in the heat exchanger core are oriented such that primary fluid flow through the primary flow subset passageways flows opposite secondary fluid flow through the secondary flow subset passageways.
