Abstract

Insbesondere zum Einsatz in Brennwert-Heizkesseln wird ein Wärmetauscherrohr geschaffen, das zwischen seinen Anschlußquerschnitten (1) einen als flachen Kanal (2) gestalteten Rohrteil aufweist, dessen Querschnitt an das Volumen der innen durchströmenden Heizgase angepaßt ist. Durch Prägungen, Sicken (7), Riefen und/oder Beschichtungen an der Rohrwand entsteht eine turbulente Grenzschicht ohne nennenswerte Kernströmung auf der Heizgasseite mit günstigem Wärmeübergang.

In particular for use in condensing boilers, a heat exchanger tube is created which, between its connection cross sections (1), has a tube part designed as a flat channel (2), the cross section of which is adapted to the volume of the heating gases flowing through it. Embossing, beads (7), scoring and / or coatings on the pipe wall create a turbulent boundary layer without any noteworthy core flow on the hot gas side with favorable heat transfer.
