Beschreibung
Zusammenfassung:	A heat exchanger is disclosed. The heat exchanger includes a hollow tube extending from a tube inlet to a tube outlet. The hollow tube includes a wall that includes a core of a first aluminum alloy, and a cladding over the core of a second aluminum alloy. The second aluminum alloy is less noble than the first aluminum alloy and includes an alloying element selected from tin, indium, or gallium, or combinations thereof. A first fluid flow path is disposed along an inner surface of the wall from the tube inlet to the tube outlet, and a second fluid flow path is disposed across an outer surface of the wall.
