Abstract
A method for forming a manifold for use with a heat exchanger is disclosed. The method may involve forming a plurality of vanes. Opposing surfaces of each of the vanes may define a pair of adjacent flow channels for receiving portions of first and second fluids to be flowed through the flow channels. Each of the flow channels may have a changing aspect ratio along its length.

A method for forming a manifold for use with a heat exchanger core, comprising:
- disposing a plurality of vanes proximate to an interface end of a wall structure and within a fluid passageway which is defined by the wall structure, the wall structure includes an inlet end and the interface end,
- wherein the interface end forms an opening to the fluid passageway and is configured to connect with the heat exchanger core,
- wherein each of the plurality of vanes extends transversely across the opening from a respective first end of the vane at a first location of the wall structure to a respective second end of the vane at a second location of the wall structure, wherein opposing surfaces of each of the plurality of vanes define a pair of adjacent flow channels within the fluid passageway for receiving portions of first and second fluids to be flowed simultaneously through the pair of adjacent flow channels, said second fluid being used to cool said first fluid, and
- wherein each of the pair of adjacent flow channels has a changing aspect ratio along its length within the manifold such that each of said pair of adjacent flow channels is twisted to form a spiral flow path along its said length within the manifold.

A method, comprising:
- receiving, with a manifold in fluid flow communication with a heat exchanger core a first fluid to be cooled at the heat exchanger core and a second fluid previously heated at the heat exchanger core, wherein the manifold comprises a wall structure defining a fluid passageway, the wall structure includes an inlet end and an interface end, wherein the interface end forms an opening to the fluid passageway and is configured to connect with the heat exchanger core;
- and
- directing, using a plurality of vanes disposed within the fluid passageway and proximate the interface end, the first fluid to the heat exchanger core through a plurality of first flow channels and the second fluid from the heat exchanger core through a plurality of second flow channels, wherein each of the plurality of vanes extends transversely across the opening from a respective first end of the vane at a first location of the wall structure to a respective second end of the vane at a second location of the wall structure, and the plurality of vanes defines the plurality of first and second flow channels in a parallel arrangement, and such that each of the plurality of first and second flow channels has a changing aspect ratio along its length within the manifold, and the plurality of first flow channels each form a spiral flow path along their lengths within the manifold.
A method, comprising:
- receiving first and second fluids respectively at first and second inlets of first and second manifolds, wherein the first and the second manifolds respectively include first and second wall structures defining respective first and second fluid passageways, the first and the second wall structures respectively include first and second inlet ends and respectively include first and second interface ends, wherein the first and the second interface ends form respective first and second openings to the first and the second passageways, and the first and the second openings are configured to connect with a heat exchanger core;
- directing respectively, with a plurality of first and second vanes respectively disposed within the first and the second fluid passageways proximate to the first and the second interface ends, the first and the second fluids to the heat exchanger core in respective spiral paths through the first and the second manifolds, wherein each of the plurality of first vanes extends transversely across the first opening from a respective first end of the first vane at a first location of the first wall structure to a respective second end of the first vane at a second location of the first wall structure, and each of the plurality of second vanes extends transversely across the second opening from a respective first end of the second vane at a first location of the second wall structure to a respective second end of the second vane at a second location of the second wall structure;
- transferring heat between the first and the second fluids at the heat exchanger core;
- and
- directing, with the plurality of second and first vanes, the first and the second fluids from the heat exchanger core to outlets of the second and the first manifolds.
