Abstract

782,525. Making heat exchangers; soldering. ESCHER WYSS AKT.-GES. Feb. 21, 1955 [Feb. 20, 1954], No. 5187/55. Classes 83 (2) and 83 (4). [Also in Group XIII] For a heat exchanger comprising a plurality of flattened tubes each lined by corrugated strips of metal which are in turn connected to plane, covering strips of metal (see Group XIII), the following method is employed for connecting together the corrugated strips and plane covering strips. Referring to Fig. 4, strips of metal 11 are unwound from the roll 12 and passed through a corrugating device 13, the corrugated strips thus formed being positioned on the covering strip 8 by means of toothed wheels 18, the number of toothed wheel equalling the number of metal strips 11. The corrugated strips and plane strip of metal, together with soldering foil 17, are then passed through an induction coil 19 so as to heat the whole and connect the corrugated strips to the plane strip, the united strips then being cooled by passing through a cooling device 20 and finally being wound on to a drum 21.
