| 摘要 |
The present invention relates to heat exchanger means (100) comprising several substantially flat and rigid elongated tubing elements (10) having a first side wall (40) and a second side wall (50) being arranged substantially parallel to each other, whereby the tubing elements (10) are forming a substantially overall cylindrical structure having a central longitudinal axis (X) and that the tubing elements (10) are spirally curved around the central longitudinal axis (X) and interleaved in the structure, whereby the tubing elements (10) have a plurality of fins (60) on at least one of the outer surfaces (42, 52) of the first side wall (40) and/or of the second side wall (50) and whereby the fins (60) are at least partially covered by a covering wall (70, 80), whereby the tubing elements (10) are at least partially tilted or at least partially tilted and sloped and at least partially helically wound and/or twisted so as to form at least a part of a helical structure, whereby preferably the helical structure has an overall cylindrical structure and/or that the helical structure is formed in a cylindrical shape. |
