Abstract (en)
[origin: JPH031092A] PURPOSE: To obtain a heat exchanger in which current velocity can be varied while sustaining simpleness of single step cooler by a structure wherein each bundle of tubes has two tube sections of different diameter coupled through a cone and the tube section having larger diameter is located at the end of the tube bundle on the gas outlet side. CONSTITUTION: The heat exchanger has a large number of tube bundles 1 having opposite ends secured to bottom plates 2, 3 which are connected with a jacket 4 while surrounding the tube bundles 1. The tube bundles 1 interconnect gas inlet and outlet chambers 7, 8. Each tube bundle 1 has two tube sections 10, 11 coupled through a cone 12. Diameter of the tube section 10 on the side facing the gas inlet chamber 7 is set smaller than that of the tube section 11 on the side facing the gas outlet chamber 8.

Ein Wärmetauscher zum Kühlen von Spaltgas ist mit einem Bündel von Wärmetauscherrohren (1) versehen. Jedes Wärmetauscherrohr (1) weist zwei Rohrabschnitte (10, 11) unterschiedlichen Durchmessers auf, die über einen Konus (12) ineinander übergehen. Der Rohrabschnitt (11) mit dem größeren Durchmesser ist am gasaustrittsseitigen Ende des Wärmetauscherrohres (1) vorgesehen.
