Abstract
A heat exchanger core includes a first hollow cylinder extending circumferentially around a center axis and extending axially along the center axis. The first hollow cylinder includes a first passage disposed radially within the first hollow cylinder and extending axially through the first hollow cylinder. A second hollow cylinder extends circumferentially around the center axis and extends axially along the center axis. The first hollow cylinder is disposed radially within the second hollow cylinder. The second hollow cylinder includes a second passage disposed radially between the first hollow cylinder and the second hollow cylinder and extending axially between the first hollow cylinder and the second hollow cylinder. The first hollow cylinder fluidically separates the first passage from the second passage. The first and second hollow cylinders and the first and second passages are spaced from one another in a sinusoidal relationship.
