Abstract
A heat exchanger of the type for directing air across a core thereof for heat transfer with fluid flowing within the core includes a pair of tubes connected in parallel between an inlet and an outlet. The tubes form a plurality of passes across the face of the heat exchanger with tube bends at the ends of each pass defining a serpentine path. A header channel extends over the bends of the passes. The header channel includes a zinc alloy coating on the interior surface thereof in contact with the bends. The zinc alloy coating provides sacrificial corrosion that prevents corrosion of the bends.
