Abstract

In order to simplify the manufacture of flow sections, e.g. for use in the matrix of a heat exchanger or as vanes or blades in turbomachines the following steps are performed during manufacture: a) thickenings (2', 3) are formed at preselected points over the circumference of a tube (1) having a substantially circular, square or polygonal cross-section; b) the tube is deformed so that the thickenings (3) are situated adjacent leading and trailing edges of the flow section (8) and other thickenings (2') form opposed separating webs; c) the opposed webs are then joined, e.g. by welding or brazing, to form at least two separate air ducts (9, 10) in the flow section. <IMAGE>
