摘要： In a double-pipe heat exchanger for cooling cracked gas, the double pipes are inserted in rows into oval pipe collectors (3), and several oval pipe collectors (3), arranged parallel to each other, are joined into a tight floor (5) which forms the upper cap of the gas entry cone. The floor (5) has a cylindrical flange collar (6) fastened to it, which is connected to a ring flange (9) attached to the gas entry cone. The gas entry cone is provided on the inside with a lining (11) whose inner contour (13) forms a central interior space (12) which widens in the direction of the floor (5). This lining (11) of the gas entry cone continues into the flange collar (6), and the inner contour (13) of the lining (11) continues all the way to the floor (5).
