The invention relates to a device () for use in the production of a tube bundle () of a wound heat exchanger (), wherein tubes () are wound in a plurality of tube layers () onto a core tube () running in an axial direction (z), webs () which run in the axial direction (z) being arranged between the tube layers (). The invention further relates to a method for producing a tube bundle using said device ().

Directed decoupling between bundle and core tube in wound heat exchangers

A heat exchanger, providing indirect heat transfer between a first fluid and at least one second fluid, comprises a jacket enclosing a jacket space for accommodating the first fluid and a tube bundle arranged in the jacket space and having a plurality of tubes for accommodating the at least one second fluid. The tubes form multiple tube layers. A shroud arranged in the jacket space encloses an outermost tube layer of the tube bundle. Spacers extending along the longitudinal axis are arranged between the shroud and the outermost tube layer. An interspace is present between any two spacers adjacent in the circumferential direction of the shroud, and between the shroud and the uppermost tube layer. A flow obstruction is arranged in the respective interspace and is designed to prevent or suppress a flow of the first fluid in the respective interspace, at least over a part section thereof.
