Abstract
A heat exchanger is disclosed. The heat exchanger includes a hollow tube including a first aluminum alloy extending along an axis from a tube inlet to tube outlet. A first plurality of fins including a second aluminum alloy extends outwardly from an outer surface of the tube. A second plurality of fins including a third aluminum alloy extends outwardly from the outer surface of the tube, interspersed along the axis with the fins including the second aluminum alloy. The third aluminum alloy is less noble than each of the first aluminum alloy and the second aluminum alloy, and includes an alloying element selected from tin, indium, gallium, or combinations thereof. A first fluid flow path is disposed through hollow tube from the tube inlet to the tube outlet. A second fluid flow path is disposed across an outer surface of the hollow tube through spaces between adjacent fins.
