Abstract (en)

The circuit, made from two flat tubes (20, 22) for exchanging heat between first and second fluids, has the tubes made with overlapping end sections (200, 220), and lengthwise main sections (203, 223) positioned side by side. The end and main sections lie in the same planes and are joined by connecting sections (201, 221). Both tubes have a constant crosssection and internal partitions forming lengthwise flow channels, and a motor vehicle heat exchanger contains a series of the flat tubes in pairs between manifolds.
