Abstract: A heat exchanger includes a first fluid pathway enclosed in a heat exchanger body to convey a first fluid through the heat exchanger body and a second fluid pathway enclosed in the heat exchanger body to convey a second fluid through the heat exchanger body and facilitate thermal energy exchange between the first fluid and the second fluid. The first fluid pathway and the second fluid pathway together are arranged in a spiral arrangement extending along a central axis of the heat exchanger.

Abstract: A plug that can seal an aperture in a body includes a base, a main plug portion extending outward from the base, a groove body portion extending from a distal end of the main plug portion and having an outer diameter and a cap receiving portion extending from a distal end of the groove body portion and having a smaller outer diameter than the outer diameter of the groove body portion. The plug also includes a cap installed on the cap receiving portion and a radial sealing element disposed between the cap and the distal end of the main plug portion, the radial sealing element having an inner diameter that is larger than the outer diameter of the cap receiving portion. In operation, the cap is installed onto the cap receiving portion after the radial sealing element has been attached.

Abstract: A heat exchanger includes first fluid passages that each have a first inlet that communicates into a first core passage and then a first outlet. The first inlet has a first inlet cross-sectional perimeter. The first core passage has a first core cross-sectional perimeter. Second fluid passages are interleaved with the first fluid passages. Each of the second passages have a second inlet that communicates into a second core passage and then a second outlet. The second inlet has a second inlet cross-sectional perimeter. The second core passage has a second core cross-sectional perimeter. The first and second core cross-sectional perimeters are larger than their respective first and second inlet cross-sectional perimeters. The first and second core passages are undivided from their respective first and second inlets to their respective first and second outlets.

Abstract: A heat exchanger includes a first fluid inlet, a first fluid outlet, a second fluid inlet, a second fluid outlet, and a core section. The core section includes a plurality of first fluid passages through which a first fluid is flowed, and a plurality of second fluid passages through which a second fluid is flowed to exchange thermal energy with the first fluid. The first fluid passages and the second fluid passages extend non-linearly along a length of the first fluid passages and the second fluid passages between a first core end and a second core end opposite the first core end. A manifold is operably connected to the plurality of first fluid passages. The manifold includes a plurality of lateral passages intersecting the plurality of first fluid passages. The plurality of lateral passages vary in length depending on distance from a fluidly upstream end of the core section.

Abstract: A monolithic open cell structure apparatus including an open cell structure housing including a first side, a second side opposite the first side, a first opening located at the first side, and a second opening located opposite the first opening at a second side. The monolithic open cell structure apparatus also including a filtration portion extending from the first side to the second side within the open cell structure housing. The monolithic open cell structure apparatus further including a retaining partition that at least partially encloses the filtration portion within the open cell structure housing. The monolithic open cell structure apparatus is a single piece including a unitary structure.

Abstract: Systems and methods to control fabrication of an assembly involve a first end sheet having an interior surface and an exterior surface, opposite the interior surface. A system includes interior sheets, the interior sheets including a first interior sheet at one end of a stack of the interior sheets and including a last interior sheet at an opposite end of the stack of the two or more interior sheets, the first interior sheet being adjacent to the interior surface of the first end sheet, and a second end sheet having an interior surface and an exterior surface, opposite the interior surface. The last interior sheet is adjacent to the interior surface of the last end sheet, and the interior surface of the first end sheet or the second end sheet includes venting features, the venting features including holes or slots to channel heat, gas, or vapor during a brazing process.

Abstract: A mating assembly is provided and includes a first mating component, a second mating component, a bolt to bolt first and second mating components together and an alignment pin. The alignment pin aligns the first and second mating components so that the first and second mating components can be bolted together. The alignment pin is configured to yield upon an application of a specified load thereto. A magnitude of the specified load is less than magnitudes of loads expected to be transferred between the first and second mating components through the bolt once bolting is complete.

Abstract: A core section of a heat exchanger includes a plurality of first fluid passages through which a first fluid is flowed, and a plurality of second fluid passages through which a second fluid is flowed to exchange thermal energy with the first fluid. The plurality of first fluid passages and the plurality of second fluid passages extend non-linearly along a length of the first fluid passages and the second fluid passages between a first core end and a second core end opposite the first core end. The first fluid passages and the second fluid passages have geometry formed to maximize primary heat transfer area.
