[Class 64 (iii)] Tubular heat-exchangers, e.g. radiators for motor-vehicles, are formed of rows of tubes of convexo-concave crosssection threaded through, common corrugated or flat fins and secured at their ends to upper and lower headers. The corresponding tubes of the rows are preferably arranged on a sinuous line, and groups of tubes in each row may be disposed oppositely to the other tubes of the same row.
