<p>The heat exchanger has exchanger plates (1) connected in stack and sealingly soldered with each other. A main channel of a fluid e.g. engine oil of a lubricant loop of an internal combustion engine, extends in a stack direction, and is formed by aligned through-holes (8) of the individual plates. A cover plate (4) is soldered with an upwardly curved outer edge of the top exchanger plate, and is soldered with an edge of the main channel in a fluid sealing manner. A reinforcement plate (5) is externally fixed on the cover plate by soldering, and is arranged in a region of a main channel.</p> |
