Abstract

1,240,749. Making heat exchangers. OLOFSTROM A.B. 2 Dec., 1969 [3 Dec., 1968], No. 58808/69. Heading B3A. A method of making an end plate for a heat exchanger which consists of a distributing and a collecting vessel for heat exchange medium linked by rows of flat tubes having their longer sides facing each other comprises pressing a recess 8 into an end plate 5, the recess being at least as long as a tube row but of less width than the tubes and having opposed pairs of widened portions 9, and drawpunching holes 7, Fig. 5, in the widened portions to produce collared holes for receiving the flat tubes. The width of the recess is preferably 60 to 80% of the width of the tubes and of the same depth as the collar to be produced around the holes. The tubes are secured to the end plates by soldering.
