Beschreibung
Zusammenfassung:	The tube has fluid circulation channels defined by a primary face of a primary portion and a secondary face of a secondary portion. The primary face comprises longitudinal grooves (18) defining the channels. The primary portion is realized in a primary material coated with a secondary material i.e. soldering material. The primary face is realized in same material of the groove. The secondary portion is formed by folding of parts (34, 36) of plates (30) made of a third material and the groove, where the primary and third materials are steel and aluminum. Independent claims are also included for the following: (1) a heat exchanger comprising a manifold for receiving ends of heat exchanging tubes (2) a method for fabrication of a heat exchanging tube.
