Abstract

The tube (1) e.g. of a metal such as copper, having an external diameter of some 5 - 20 mm, has a series of lengthwise inner ribs (2) measuring 0.15 - 1.5 mm high and about 1 mm apart. The ribs have an initial asymmetrical triangular cross-section with straight sides, with the tip of each rib offset to one side of its base. The ribs are subsequently curved by passing an olive (3) through the tube, so that the gaps between the tips of adjacent ribs are smaller than the gaps between the ribs' bases. The shaping of the ribs can be carried out at the same time as fins are crimped to the outside of the tube.
