Process for the production of a heat exchanger and apparatus for

A heat exchanger includes exchanger tubes which are narrow in flow direction of an outer exchanger medium. Always two adjacent exchanger tubes are connected to each other by fins which are either U-shaped individual or are components of a meander-like fin strip. The tube sides are connected to bases of the individual fins or to contact portions of the fin strips by welding, particularly by fusion welding on the inner surfaces of the tube sides. The exchanger tubes are formed by two tube shells which are welded together at the longitudinal edges thereof after two adjacent tube shells have been connected to each other by the fins. The ends of the tubes are placed in tube plates. The resulting heat exchanger is completely galvanized and does not require support structures.
