Abstract: A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold comprises a inlet header, a outlet header, and a multi-helical core section. The inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed laterally across a plane normal to the first fluid axis. The outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The multi-helical core section fluidly connects the inlet header to the outlet header via a plurality of laterally distributed helical tubes, each helical tube corresponding to one of the plurality of first fluid branches and oriented parallel to all others of the plurality of helical tubes at each axial location along the first fluid axis.

Abstract: A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold includes a first fluid inlet header, a first fluid outlet header, and a nested helical core section. The first fluid inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed circumferentially and radially about the first fluid axis. The first fluid outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The nested helical core section fluidly connects the first fluid inlet header to the first fluid outlet header via a plurality of nested helical tubes, and includes radially inner and outer groups of circumferentially distributed helical tubes.

Abstract: A check valve housing for a check valve is provided and includes check valve housing body. First and second hinge supports extend from the check valve housing body. A stop is coupled to the first and second hinge supports. The first hinge support includes a first hinge pin interface having a first hinge pin hole to receive a hinge pin. A ratio of a diameter of the first hinge pin hole to a thickness of the first hinge pin interface is between 2.44 and 2.66.
