The method of producing heat exchanger elements involves heat-transfer surfaces (1), pipes (2)conveying cooling or heating medium, and curved tubular parts (3). An extruded aluminum section is produced with a flat arm as heat-transfer surface and an enclosed tubular part containing the heating or cooling medium. The arm is removed in the area (4) between the heat transfer surfaces. The remaining part of the pipe is bent between the heat transfer surfaces. |
