Abstract

138,080. Aktiebolaget Ljungstr÷ms Angturbin. Jan. 21, 1919, [Convention date]. Tubes of special section; gills for tubes.-The elements of a heating or cooling apparatus are formed of flattened tubes having projecting ribs 3 arranged on the tubes so that the ribs of adjacent tubes cross one another as shown in Fig. 1. In a modification, the ribs on one side of the tube cross the ribs on the other side. In addition, both sides of the tube may be provided with trough-like depressions 4 in contact at their inner surfaces to prevent the sides from collapsing.
