  • Method of assembling tube arrays
    Patent number: 4896410
    Abstract: A method of assembling a plurality of microtubes rigidly into position so as to facilitate their rapid interference pressing into metallic header tubestrips is disclosed that is particularly well suited for the Microtube-Strip (MTS) gas-gas counterflow heat exchanger design. The technique, utilizing fusible alloys, non-sacrificial fixtures, and a high speed, gas powered machine gun tube insertion device, permits tube alignment, insertion, and welding rates to exceed 1,500,000 pieces per day per production line at greatly reduced costs.
