Abstract

A finned heat exchange tube (10) includes a metal cylindrical central tube (11) having an outer surface (13) and a metal fin (12) helically disposed on and in thermally conductive contact with the outer surface (13) of the tube (10). The cross-section of the fin (12) is trapezoidal in shape, with a longer (B1) and a shorter base (B2), the longer base (B1) being in contact with the outer surface (13) of the tube (10). Alternatively, the fin (21) can have a cross-section substantially rectangular in shape, having rounded corners and sides of longer and shorter dimensions perpendicular to one another, a side of the shorter dimension being in contact with the outer surface (13) of the tube (20). A process for forming a heat exchanger tube (1) comprises helically winding and securing a metal fin (12) on an outer surface (13) of a metal cylindrical central tube (11). The fin (12,21), which is in thermally conductive contact with the central tubE (11), has a cross-section that can be trapezoidal or substantially rectangular in shape.
