Abstract (en)
[origin: WO9946548A1] This convectional heat exchanger is structured of tube (1) inside which there is an inner medium. There are two ends of the tube operating as an inlet and an outlet of the inner medium, if that medium is forced to flow. This tube is bent into a spiral shape at the same time with its heat exchanging element (2) which is formed of at least one flat (5) and two corrugated (3 and 4) strips occuring alternatively. The outer band (7) being an extension of the flat strip ensures permanent reciprocal contact in the tangent places of the tube and the strips.
