Tube heat exchanger for hot and cold fluids respectively with large differences respectively temperature and pressure.

摘要

The invention relates to a heat exchanger CASING CYLINDER (1) containing PIPES STRAIGHT fluid passage (6) and fixed, at its opposite ends, respectively to two tubular plates (5) being connected to at least one of these a flexible coupling (7). BETWEEN THE FLEXIBLE COUPLING (7) and the adjacent end of the housing (1) interposes an annular rigid coaxial connector (8) respectively connected to the housing (1) AND FLEXIBLE COUPLING (7) radially inner OVERHANG AND SECTION SUFFICIENT TO LIMIT INCREASE THE mAXIMUM dIAMETER OF HOUSING AND fIXING POINT SLIDING COUPLING FLEXIBLE ON UNDER THE INFLUENCE annular internal pressure. The invention is applicable in heat exchangers PLATES THIN TUBES AND PIPES OVERLENGTH.
