Abstract

See full text

A heat exchanger includes a first set of fins, a second set of fins, and an exterior wall. The first set of fins extend radially and are coaxial with each other. The first set of fins forms a first set of channels. The second set of fins extend radially and are coaxial with each other. The second set of fins forms a second set of channels. Channels of the first and second sets of channels are disposed in an alternating pattern in a circumferential direction of the heat exchanger. The first and second sets of fins are integrally formed together. A cross-sectional width of a channel of at least one of the first set of channels and the second set of channels increases as a radial distance from a centerline axis of the heat exchanger increases.
