Classification: CPC F  B | IPC B  F

Claim 0:
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.
