Abstract (en)
[origin: EP0035078A2] In a finned heat exchanger, preferably of aluminium, the feed of the fins (1) are secured to tubular passages (3, 3a, 3b) formed from plates (2) that have been rolled together and then expanded. The bond between the fins (1) and the plates (2) may be an adhesive bond, as by welding or a cohesive bond, as by tight pressing together.
