Abstract

Official abstract text for this publication.

A heat exchanger includes a body, a plurality of first flow channels defined in the body; and a plurality of second flow channels defined in the body. The second flow channels are fluidly isolated from the first flow channels. The first flow channels and second flow channels are arranged in a checkerboard pattern.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of manufacturing a heat exchanger, comprising; forming a body having a first end and a second end, and a constant total cross sectional area between the first end and the second end, the body comprising: a plurality of first flow channels defined in the body between the first end and the second end; and a plurality of second flow channels defined in the body between the first end and the second end, wherein the first flow channels and the second flow channels are fluidly isolated from one another, and are arranged in a checkerboard pattern; and wherein the first and second flow channels include a changing cross-sectional shape along a length of the body, the first flow channels at a first end thereof, having a first cross-sectional shape, the first flow channels at a second end thereof, having a second cross-sectional shape, the first cross-sectional shape being different than the second cross-sectional shape, the second flow channels at a first end thereof, having the second cross-sectional shape, the second flow channels at a second end thereof, having the first cross-sectional shape, the first and second flow channels remaining flush against one another between the first and second ends of the body. 2. The method of claim 1 , wherein forming the heat exchanger includes additively manufacturing the heat exchanger. 3. The method of claim 2 , wherein additively manufacturing the heat exchanger includes monolithically forming a header transition portion in fluid communication with the flow channels. 4. The method of claim 3 , wherein forming the header transition portion includes modifying the checkerboard pattern to transition into an aligned pattern to fluidly connect to a header within the header transition portion. 5. The method of claim 4 , wherein additively manufacturing the heat exchanger includes monolithically forming the header in fluid communication with the header transition portion.
