Abstract:
Multi-port tube structures are fabricated in a process in which a web of metallic material has a pattern of features formed therein by a rotary die forming process carried out on a continuous basis. The web of material is cut into strips which are folded so as to define a closed tubular structure having internal features defining longitudinal fluid flow channels.
