Abstract
(DE)
Die Erfindung betrifft ein Flachrohr (1) mit zwei gegenüberliegenden und parallel zueinander angeordneten im Wesentlichen flachen ersten Wandungen (2, 3) und mit zwei die beiden flachen ersten Wandungen (2, 3) verbindenden bogenförmigen zweiten Wandungen (4, 5), mit einem Innenraum (6) zur Durchströmung eines Mediums, wobei in zumindest einer der flachen ersten Wandungen (2, 3) in den Innenraum (6) ragende Vorsprünge (7) vorgesehen sind, wobei in den bogenförmigen zweiten Wandungen (4, 5) in den innenraum (6) ragende Vorsprünge (11) vorgesehen sind.
(EN)
The invention relates to a flat pipe (1), comprising two substantially flat first walls (2, 3) that are opposite each other and arranged parallel to each other, two arcuate second walls (4, 5) that connect the two flat first walls (2, 3), and an interior (6) through which a medium can flow, wherein projections (7) that protrude into the interior (6) are provided in at least one of the flat first walls (2, 3), wherein projections (11) that protrude into the interior (6) are provided in the arcuate second walls (4, 5).
(FR)
L'invention concerne un tube plat (1) comprenant deux premières parois (2, 3) pratiquement plates opposées et disposées parallèlement entre elles et deux deuxièmes parois (4, 5) en forme d'arc reliant les deux premières parois (2, 3) plates, un espace intérieur (6) pour la circulation d'un fluide, des saillies (7) s'avançant dans l'espace intérieur (6) étant prévues dans au moins une des premières parois (2, 3) plates et des saillies (11) s'avançant dans l'espace intérieur (6) étant prévues dans les deuxièmes parois (4, 5) en forme d'arc.
