Verfahren zur Herstellung eines Rohrbündelwärmetauschers.

摘要

The invention relates to a heat exchanger comprising a bundle formed by a multiplicity of parallel tubes (10), arranged in at least one row and in which each tube (10) has a body (12) ending with an extremity (16) received in a hole (18) of a collector plate (20). …The cross-section (S2) of the extremity (16) of the tube has a perimeter which is smaller than the perimeter of the cross-section (S1) of the body (12) of the tube. …The invention thus makes it possible to optimise the value of the distance (ER) between the tube axes and to reduce the overall size of the heat exchanger. ……
