Abstract: A method and apparatus for manufacturing elongate heat-exchanger blanks composed of a basic substrate profile having at least one length of corrugated metal foil strip mechanically bonded thereto. A basic elongate profile string is advanced at a predetermined speed along a fixed path and at least one strip corrugating device is arranged to produce a continuous length of corrugated strip and to feed the strip into the path of the basic profile via a number of corrugated strip cutting and feed means. These latter means operate cyclically to cut the strip at predetermined intervals and to join the cut lengths of strip to the basic profile string in spaced relationship at a frequency corresponding to the intervals.

Abstract: A method and apparatus for producing highly effective heat exchanger elements of the type which comprise corrugated surface enlarging members of strip material fixed to thin-walled substrates. The strip material, which can be either precorrugated or corrugated synchronously with the heat-exchanger element manufacturing process and which has a thickness of from 50-10 Mu m, is advanced concurrently with a substrate material to a station at which the strip is lightly held in firm abutment with the substrate material by means of an impringing stream of gaseous medium and simultaneously metallurgically bonded to the substrate. The composite product is then cut into lengths to form finished heat exchanger elements.
