Claim 13:
14. The method for exchanging heat according to claim 12, wherein in a first section (31) of the tube bundle (2) in which turbulence or a pressure loss of the second fluid provided in the shell space (M) influences the heat exchange between the first fluid and the second fluid, the windings (23) of at least one tube layer (22) have a radial distance (D) from the longitudinal axis (L) that differs from a radial distance (D) of the windings (23) of the respective tube layer (22) from the longitudinal axis (L) in a second section (32) of the tube bundle (2) adjacent to the first section (31) in the axial direction (a), wherein in the second section (32), the turbulence or pressure loss of the second fluid causes a reduced influence on the heat exchange between the first fluid and the second fluid, wherein the radial distance (D) of the windings (23) of said tube layer (22) from the longitudinal axis (L) in the first section (31) of the tube bundle (2) is smaller than the radial distance (D) of the windings (23) of said tube layer (22) from the longitudinal axis (L) in the second section (32) of the tube bundle (2).
