Claim 4:
5. The wound heat exchanger (1) according to claim 4, wherein said at least one of said plurality of tube layers (22) has in the first section (31) a first number (n1) of windings (23), a first height (h1) extending in the axial direction (a) and a first packing density (p1), wherein the first packing density (p1) is equal to the quotient (n1/h1) of the first number (n1) and the first height (h1), and wherein said at least one of said plurality of tube layers (22) has in the second section (32) a second number (n2) of windings (23), a second height (h2) extending in the axial direction (a) and a second packing density (p2), wherein the second packing density (p2) is equal to the quotient (n2/h2) of the second number (n2) and the second height (h2), and wherein the first packing density (p1) differs from the second packing density (p2).
