    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: 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.

    Abstract: A heat exchanger includes a plurality of mini-channel tubes. The mini-channel tubes extends for an axial length defined between two manifolds. The mini-channel tubes include a plurality of generally rectangular flow passages. The generally rectangular flow passages are aligned adjacent to each other to define a lateral dimension. A first lateral width of the generally rectangular passages is defined with a ratio of the axial length to the first lateral width being between 201.3 and 215.3. An aircraft system is also disclosed.

    Abstract: A heat exchanger includes a plurality of first and second fluid passages. The first fluid passages are defined by a pair of opposing first fluid passage walls and a plurality of first fluid diverters disposed between the first fluid passages walls. The second fluid passages are defined by a pair of opposing second fluid passage walls and a plurality of second fluid diverters disposed between the second fluid passage walls. The second fluid diverters include a body portion and a leading edge portion. The first fluid passage walls form a first fluid leading edge that extends upstream of the leading edge portion of the second fluid diverters. The second fluid passages extend in a direction perpendicular to the direction of the first fluid passages.

    Abstract: An embodiment of a heat exchanger according to the disclosure includes a core configured to receive and place a plurality of mediums in at least one heat exchange relationship, and a first manifold connected to and in fluid communication with the core at a first manifold/core interface. The first manifold includes a first end distal from the core with at least one port adapted to receive or discharge a first medium of the plurality of mediums, and a second end joined to the core at the first manifold/core interface adapted to transfer the first medium to or from a plurality of first heat exchange passages in the core. A plurality of first guide vanes in the manifold defining individual layers for the first medium, and a plurality of second guide vanes divide ones of the individual layers into a plurality of first discrete manifold flow passages extending at least part of a distance from the first end to the second end of the first manifold.
