Abstract (en)

The stacked plate oil cooler has a first plate 1 and a second plate 2. Both the first plate 1 and the second plate 2 are made of a three-layered aluminum alloy clad sheet. The second plate 2 is folded at an outer rim to place the brazing material layer 35 on both sides of the second plate 2. The first and second plates 1 and 2 are stacked alternately and brazed to define a water passage 21 between sacrificial layers 32 and 36, and to define an oil passage 22 between brazing material layers 33 and 35. The first plate 1 is folded at an outer rim to place the sacrificial layer 32 on a lateral outside of a core assembly to decrease exposure of the brazing material layer to the lateral outside.
