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.

Heat exchanger with build powder in barrier channels

An embodiment of a heat exchanger assembly includes a first manifold adapted for receiving a first medium, a core adapted for receiving and placing a plurality of mediums, including the first medium, in at least one heat exchange relationship, and a core meeting the first manifold at a first core/manifold interface; The mounting structure supports a heat exchanger, and is metallurgically joined to at least one heat exchanger assembly component at a first joint integrally formed with the mounting structure.

Integral heat exchanger mounts

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.

Heat exchanger with barrier passages

A heat exchanging arrangement includes a first flow circuit for a first fluid to be cooled, which has a first inlet, a first outlet, and a second outlet. The heat exchanging arrangement includes a second flow circuit for a second fluid, which is in thermal communication with the first flow circuit. The heat exchanging arrangement includes a third flow circuit configured to port a portion of the first fluid from a first location of the first flow circuit to a second location of the first flow circuit, the first location being downstream of the second location.

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.

Heat exchanger with integral anti-icing

A method of forming an integral drain for a heat exchanger is provided. The method includes forming a plurality of passage walls to define a plurality of passages with an additive manufacturing process, each of the passage walls having a non-linear portion. The method also includes integrally forming a drain wall with at least one of the passage walls with the additive manufacturing process to define a drain for each of the plurality of passages, the drain wall located proximate the non-linear portion of each of the plurality of passage walls.

A water extractor includes an inlet, an outlet a body, outer wall, inner wall, helical wall, plurality of catchment areas, and scuppers. The body extends between the inlet and the outlet. The inner wall is disposed radially inward from the outer wall and forms a main flow channel through a portion of the body. The helical wall extends between and is connected to the outer wall and the inner wall and forms a helical passageway fluidly connected to the inlet and the outlet. The helical passageway includes a plurality of turns along a bottom of the body. One of the catchment areas is disposed in each turn of the helical passageway. The scuppers are disposed in the catchment areas and are connected to and extend radially inward from the outer wall.

Method of extracting water

A clamp assembly includes a first arm, a second arm, a hinge, and a fastening arrangement. The first arm and the second arm each include a hinge end, a free end, a web between the hinge end and the free end, a curved portion between the hinge end and the web, and a curved portion between the free end and the web. The hinge pivotably connects the hinge ends. The fastening arrangement is configured to connect the free ends when the clamp assembly is in a closed position. The curved portions are configured to encircle a first structure and a second structure when the clamp assembly is in the closed position.

Clamp assembly and method of clamping

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.
