Abstract: A fluid manifold includes an inlet comprising an opening into an interior of the fluid manifold, an outlet end that is positioned opposite the inlet and that is in fluid communication with the inlet, a shroud extending between the inlet and the outlet end and surrounding a flow path of the fluid manifold, and a first flow distributor positioned within the interior of the fluid manifold. The first flow distributor includes a hollow body including a first surface at a downstream side of the first flow distributor and a second surface at an upstream side of the first flow distributor, a central cavity defined by the second surface of the hollow body, and openings extending from the first surface to the second surface such that a fluid can pass from the central cavity through the openings. The first flow distributor and the fluid manifold are integrally formed.

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 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 method of manufacturing a pump inlet housing and filter for a pump assembly, wherein the pump inlet housing and filter are monolithic, the method has the steps of: defining a pump inlet housing as a housing tubular shape with an inlet aperture boundary at a housing top end, and an outlet aperture boundary at a housing bottom end; defining a lattice filter between the inlet and outlet aperture boundaries; and performing an additive manufacturing (AM) process to additively manufacture the pump inlet housing and the lattice filter such that the lattice filter is integral with the pump inlet housing.

Abstract: A heat exchanger and a method of assembling the heat exchanger involve a monolithic main body extending along an axis from a first end to a second end. The heat exchanger includes a plurality of flow channels to channel a first material from an inlet to an outlet. Each of the plurality of flow channels traverse a spiral flow path from the inlet at a center of the main body to the outlet at an exterior surface of the main body, and the plurality of flow paths are aligned along the axis. The heat exchanger also includes a plurality of passages to hold a second material, each passage extending along the axis from the first end to the second end. A first side and a second side, opposite the first side, of each of the passages is defined by the spiral flow path of the plurality of flow channels.
