- ) having a first side wall (40) and a second side wall (50) being arranged substantially parallel to each other, whereby the one or more finned tubing elements (10, 10′
) form a substantially overall cylindrical structure having a central longitudinal axis (X) and that the one or more finned tubing elements (10, 10′
) are curved around the central longitudinal axis (X),whereby the one or more finned tubing elements (10, 10′
) have a plurality of fins (60, 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, 60′
) are angled and not perpendicular with respect to lengths of the one or more finned tubing elements (10, 10′
) to direct flow across the sidewalls (40, 50), connection walls (45, 55) on both sides between the first side wall (40) and the second side wall (50),wherein the fins (60, 60′
) are angled with respect to the finned tubing element by two defining angles (γ
, δ
), wherein one angle (γ
) of the two defining angles is an angle of the fins (60, 60′
) with respect to the connection walls (45, 55) of the finned tubing element, wherein another angle (δ
) of the two defining angles is an angle of the fins (60,60′
) with respect to the outer surfaces (42, 52) of the first side wall (40) or the second side wall (50),wherein the fins are covered by a covering wall (70, 80), whereby the one or more finned tubing elements (10, 10′
) are at least partially tilted, sloped, and helically wound and twisted so as to form at least a part of a helical structure, whereby the helical structure has an overall cylindrical structure and that the helical structure is formed in a cylindrical shape, wherein each of the fins is twisted between opposite endpoints of each fin and curved by an offset of a center part of a middle section of each fin with respect to the endpoints of each fin.

Abstract
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.
