摘要：Multi-port tube structures are fabricated in a process in which a web of metallicmaterial 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 todefine a closed tubular structure having internal features defining longitudinal fluid flowchannels.
