Abstract: A heat exchanger is provided. The heat exchanger includes a core that receives a plurality of mediums. The heat exchanger includes a manifold. The manifold includes a first end that receives a first medium of the plurality of mediums. The manifold includes a second end that intersects the core at a manifold/core interface. The manifold includes a plurality of individual layers that provide gradual transitions for the first medium from the first end to the second end to reduce or eliminate discontinuities at the manifold/core interface that cause stress to the heat exchanger.

Abstract: A vibration damping component for a vehicle includes a housing, and a mounting lug attached to the housing. The mounting lug includes an outer shell with a top, a bottom, and sides. The mounting lug also includes a bore through the outer shell from the top to the bottom. The mounting lug also includes a cavity, an interior lattice, and a damping media. The outer shell and the bore enclose the cavity. The interior lattice is within the cavity and stiffens the mounting lug. The damping media is enclosed in the cavity and between solid portions of the interior lattice.

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: 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.

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.
