Abstract (en)

[origin: EP2299223A2] The pipe has metal strips comprising a fold at a longitudinal direction (L) of the pipe so that long side walls (1, 2) of the pipe are formed by sections (1a-1e, 2a-2d) of a cross section line of the metal strips. The sections are alternatively tracked in a course of the cross section line. A separate section is formed between sections of the long side walls. Chambers of the pipe are separated from each other by the separate section. The metal strips consist of a soldered plate with aluminum base and stainless steel base. Short side walls (3, 4) exhibit a double layer of the metal strips. An independent claim is also included for a heat exchanger comprising a flat pipe and ribs.
