Abstract

694,039. Making plates for heat exchangers. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. May 23, 1950 [Jan. 13, 1950], No. 12867/50. Classes 83 (ii) and 83 (iv). [Also in Group XIII] Corrugating.-A method in the manufacture of heat-exchange plates (see Group XIII) consists in producing a so-called " waffle pattern " on the surface of the plate by two rolling operations, the plate being first corrugated in one direction and then in another direction, one set of corrugations being of less depth than the other so that crests of the deeper set of corrugations are deformed at spaced intervals. Rolling apparatus for producing the plates comprises rollers so profiled as to produce in combination the desired " waffle pattern," which may be produced by passing the plate in two different directions through a single pair of rolls 74, 76, Fig. 4, these rolls being either undulated transversely to the axis of the roller shafts (as shown) or parallel thereto, or alternatively by passing the plate successively through two sets of spirally undulated rolls 80, 82 and 84, 86, Fig. 5. The required pattern may however be produced by passing the plates through a single pair of rollers in a single pass.
