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 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: A flow manifold for a heat exchanger core includes a number of fractal flow splitters arranged in a grid pattern of layers each fluidly connected to a corresponding first circuit layer, a flow plenum having a number of flow channels that are fluidly connected to an associated fractal flow splitter, one or more flow dividing vanes located in each flow channel thereby dividing the associated flow channel into two or more sub-channels, and an outer manifold surrounding the fractal flow splitters and configured to direct a first circuit flow into or out of the heat exchanger core. Each fractal flow splitter has an open end and a plenum end, and provides a transition from the open end to the flow plenum.

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.

Abstract: An embodiment of a heat exchanger core includes a plurality of walls defining a plurality of layers in at least one heat exchange relationship. At least one of the layers of the core having a first load-bearing portion aligned with and adjacent to a first mount location on a perimeter of the core, and a first non-load-bearing portion distal from the non-load-bearing portion. A topology of the first load-bearing portion has a load bearing capacity greater than a load bearing capacity of the non-load-bearing portion.

IPC: F16L3/237
Abstract: 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.
