Support of heat exchangers made of wound tubes

A heat exchanger (1), comprising:

• a tube bundle (3) having at least one tube (30) for receiving a fluid medium (M), wherein the at least one tube (30) is wound around a core tube which extends along a longitudinal axis (z), wherein the at least one tube (30) rests with a first tube section (31) against at least one web (10) which extends along the core tube (300), and
• at least one first bracket element (41) for fixing the first tube section (31) on the at least one web (10), wherein the at least one first bracket element (41) rests with a lower face (41a) facing the first tube section (31) against the first tube section (31),
• wherein the at least one first bracket element (41) has at least one first securing region (411), which forms an elevation (400) on an upper face (41b), facing away from the lower face (41a), of the at least one first bracket element (41), and which forms a depression (401) on the lower face (41a) of the at least one first bracket element (41), and
• wherein the at least one first securing region (411, 412, 413, 414) of the at least one first bracket element (41) is welded to an additional bracket element (42, 43) or to an additional web (10) via a welded connection (S).
