Abstract (en)
[origin: EP1209434A2] Heat exchanger for indirect heat exchange of two gaseous media consisting of at least one aggressive component containing e.g. sulfuric acid comprises a chamber through which one medium flows and pipes (1) for the other medium passing through the chamber. The ends of the pipes are fixed in a gas- and liquid-tight manner in at least one pipe base (4) separating the media from each other. The pipes are made of plastic with walls forming a zigzag pattern (5). The zigzag patterns on the inner side and the outer side correspond with each other. The sides (6) on the inner side of the zigzag pattern angled downward lie at a smaller angle ( alpha ) to the pipe middle axis (1a) than the sides (7) angled upward. Preferred Features: The angle ( beta ) of the sides angled upward is 1.3-2 times the angle ( alpha ) of the sides angled downward.
