Aluminum heat exchanger with soldered connecting area has core area comprising several pairs of first and second plates laminated and soldered with one another, each first and second plate being formed by core component
The aluminum heat exchanger with a soldered connecting area has a core area comprising several pairs of first and second plates (1,2) laminated and soldered with one another. Each first and second plate is formed by a core component consisting of a solder filling metal layer formed on the surface of the core component. A corrosion-proof layer is formed on the other surface of the core component. For formation of a pair from the first and second plates, the first plate is formed with a convex area with an opening area. An edging area of the second plate is inserted in the opening area and is so plastically deformed that the corrosion-proof layer of the second plate, the solder filling metal layer of the first plate are i close contact. The first and second plates are then soldered to each other.
