| 摘要 |
Heat exchanger (100) has one or several substantially flat and rigid elongated tubing elements (10), whereby the tubing elements (10) tilted while being helically wound, forming a substantially overall cylindrical structure having a central longitudinal axis (X). Tubing elements (10) are tilted spirally curved around the central longitudinal axis (X). Several elements are interleaved in a structure. The tubing elements (10) have a plurality of fins (60) on at least one of the outer surfaces (42, 52) of first (40) and/or second (50) side wall. Fins (60) are at least partially covered by a covering wall (70, 80). 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, an overall cylindrical structure and/or a cylindrical shape. |

1. Heat exchanger apparatus (100) comprising one or more 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) form a substantially overall cylindrical structure having a central longitudinal axis (X) and that the tubing elements (10) are tilted and spirally curved around the central longitudinal axis (X), whereby the tubing elements (10) have a plurality of fins (60) on at least one of outer surfaces (42, 52) of a first side wall (40) and/or of a second side wall (50) and whereby the fins (60) are angled and not perpendicular to lengths of the tubing elements 10 or to flow across the sidewalls (50, 60) 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 the helical structure has an overall cylindrical structure and/or that the helical structure is formed in a cylindrical shape.
