Zusammenfassung:A heat exchanger includes a plurality of longitudinally-extending first channels (12, 26) and a plurality of second channels (14, 28) fluidly isolated from the plurality of first channels. Each first channels includes a plurality of spiraling internal fins (16, 30) and a plurality of external fins (18, 20, 32). The internal fins extend from and are integrally formed with the internal walls (22, 34) of the first channel. The external fins connect extend from and are integrally formed with the external walls (24, 36) of the first channels, connecting channels together. The plurality of second channels is defined in part by external walls of the plurality of first channels and the plurality of external fins.
