Beschreibung
Zusammenfassung:	1. Flame pipe of a condensing heat exchanger features pairs of longitudinal dents (2) shaped coaxially with respect to the axis of the pipe (1), where the dents are trapezoid in longitudinal section, positioned opposite each other, pointing towards the centre of the pipe (1) and forming a section, and the distance between the dents (2) in the section measured inside the pipe (1 ) is 0.5 mm or less, and the adjacent dent sections are positioned at an angle of 90° to one another, where the ratio of the pipe length (L) to the inner diameter (S) of the pipe (1) measured in the cylindrical part devoid of dents falls within the range from 26 to 29.
