Title: Heat exchanger core having fin members serving as sacrificial anodes

Abstract: The heat exchanger core comprises a fluid passage member, within which a fluid flows and outside of which another fluid flows and fin members formed on the fluid passage member for promoting heat exchange between the two fluids. The fluid passage member and the fin members are made of different kinds of aluminum alloys. The fin members serve as sacrificial anodes as well for protecting the heat exchanger core from corrosion.
