Tube sheet for apparatus for transferring heat and/or mass, use thereof and process for its production |
摘要 |
In an injection-molded tube sheet of thermoplastic material for apparatus for transferring heat and/or mass with at least 25 through-holes for taking up tube ends, the holes have a hydraulic diameter of at most 3 mm and the minimum web width between neighboring holes is at most 0.4 mm. The thickness of the tube sheet ranges from 3 to 10 mm. Such a tube sheet is particularly suitable for the compact arrangement of tube ends and is therefore used for producing apparatus for transferring heat and/or mass. It is fabricated by an injection-molding process in which the melt is first distributed in the injection mold over the cross-sectional area before being pressed into the region of the tube sheet proper.
