Abstract (en)
[origin: EP0864830A1] The heat exchanger, with U-shaped pipes, has the inner and outer legs of the U-pipes (2) located on two concentric arcs. The inner legs surround the axis of a central pipe (11) of the heat exchanger, connected to the inlets (5) and open to the interior of the heat exchanger, to extend from one end of the heat exchanger to a point near the pipe base (3) at the other end of the heat exchanger. A dividing mantle (12) is between the inner and outer legs of the U-pipes (2), connected to the pipe base (3). The guide mantle (13) is tightly bonded to the central pipe (11) at one end, with its open end reaching almost to the pipe base (3). The outlet fitting (7), from the ring zone (14) between the guide (13) and pressure (1) mantles, is at the end of the heat exchanger away from the open end of the guide mantle (13).
