Abstract

Heat exchanger including progressively angled or over their length slightly spirally wound tubes (1, 2) extending between two tube plates (4). The tubes (1 and 2) are arranged in two concentric circles and the tubes of the different circles are given differing progression so that the same tube length can be used in the different concentric circles of the tubes. The tubes (1, 2) are corrugated over their length and the rings of tubes are in close contact with each other. In the end of the tubes the tube plates (4) are achieved by widening the ends of the pipe so that they come in contact with each other, whereafter the ends are soldered to each other. The tube bundle is surrounded by a tight fitting shell (3) and wide surrounding connections (5, 6) allowing the heat exchanger to be easily coupled in series parallel etc. <IMAGE>
