Abstract
A core for a housingless oil cooler has alternate cooling water passageways and oil passageways, including two sets of aluminum plates coated on one side with a sacrificial corrosion layer and on the other side with a brazing filler metal layer, each plate having a peripheral rim projecting from the outer periphery. The plates of the first and second sets are assembled alternately and arranged so that the brazing filler metal layer coated on each plate of the first set is adjacent to the sacrificial corrosion layer of the next plate of the first set and the plates of the second set have a sacrificial corrosion layer opposed to the sacrificial corrosion layer of the adjacent plate of the first set to define a cooling water passageway therebetween, and the brazing filler metal layer on the outer surface of the peripheral rim of the plates of the second set is bonded to the inner surface of the peripheral rim of the adjacent plate of the first set.
