A pin for a heat exchanger. The pin includes: a monolithic top section; a monolithic bottom section; and a middle section comprising a plurality of spaced apart sub-pins extending between the top section and the bottom section, wherein the plurality of sub-pins define one or more windows for allowing fluid flow through the middle section. Also disclosed is a layer of a heat exchanger including the pin, as well as a heat exchanger including the layer, and a method of making a layer for a heat exchanger.

Heat-exchanger pins

A counter-flow heat exchanger core includes a first wall defining a longitudinal axis. The first flow path is defined within the first wall. The first flow path includes a primary flow inlet and a primary flow outlet downstream from the primary flow inlet. The heat exchanger core includes at least two hollow vanes circumferentially spaced apart and extending in a radially inward direction from the first wall. Each of the at least two hollow vanes includes a first vane wall and a second vane wall. The heat exchanger core includes a second flow path defined within the at least two hollow vanes between the first vane wall and second vane wall of each of the at least two hollow vanes. The heat exchanger core includes at least one fin extending between two of the at least two circumferentially spaced apart vanes.

Heat exchangers

A water extractor including: an inlet; an outlet; a body including a helical passageway having an exit proximate the outlet and an entrance; an elbow connector enclosing a fluid passageway that fluidly connects the inlet to the entrance of the helical passageway, the elbow connector being bent at a selected angle and including an inner radius and an outer radius opposite the inner radius; and a baffle extending from proximate the inlet to the entrance and located within the fluid passageway of the elbow connector, the baffle being configured to partition the fluid passageway into a first fluid passageway proximate the inner radius of the elbow connector and a second fluid passageway proximate the outer radius of the elbow connector.
