Claim 10:
11. A method for producing a wound heat exchanger (1) according to claim 1, comprising winding the tubes (20) around the core tube (21) in such a way that tube layers (22) adjacent to one another in the radial direction (r) have different radial distances (D) from one another in a cross-sectional plane perpendicular to the longitudinal axis (L), and the radial distances (D) of the adjacent tube layers (22) increase monotonically in the radial direction (r), in at least a section of the tube bundle (2), and
providing the plurality of webs (6) so that they extend in the axial direction (a), and function as spacers between adjacent tube layers (22) in the radial direction of the webs (6), and the webs each form a distance in the radial direction (r) between two respective adjacent tube layers (22), and
wherein (a) at least two of said plurality of webs (6) have different thicknesses (d) in the radial direction (r), and/or (b) the thickness (d) of at least one of the webs (6) varies along the axial direction (r) such that adjacent windings (23) of at least one of said plurality of tube layers (22) are spaced at different distances from the longitudinal axis.
