Abstract

The heat exchanger tubes (1, 2) contain different fluids and are mounted parallel to each other. The fluids are arranged to flow in opposite directions. The metal tubes are joined by a metal fin plate (3) which is continuously welded to the length of the tubes and on both sides. Alternatively the tubes may make contact with each other and the wedge between the tubes may be filled with weld metal. The two tubes have their axes separated by par a distance 'D' which is greater than the sum of their external radii (R1, R2).
