Abstract (en)
[origin: EP0726441A2] The profile tube components (2-4) comprises at least one fluid channel (13) and at least one side provided with ribs (12). The at least one fluid channel has a slot-type cross-section, the width of which amounts to a max. of 5 mm. The length of the slot-type cross-section is at least five times as long as its width. The profile tube components has a flat side of a structured surface. At least one side of the profile tube components provided with ribs has at least one slightly acute-angled end rib (14,15), which on the angle inner side has a convex surface (16,17), in order to be connectable via a slotted casing (18) with a further end rib.
