ABSTRACT:
A water-cooled oil cooler includes a laminated body formed by alternately piling up formed plates having cooling water passage openings and oil passage openings in the direction of plate thickness, and fin plates having cooling water passage openings and oil passage openings in the direction of plate thickness. A protrusion is projected from a passage wall of the cooling water passage opening of the fin plate into a cooling water passage. By setting the protrusion baser than the other part of the fin plate, the protrusion is made to serve as a sacrificial corrosion section to prevent the contact section from being precedently corroded.
