Helically coiled heat exchanger for the indirect exchange of heat between a two-phase first medium and a second medium has a shell surrounding a shell space, which extends along a longitudinal axis, an inlet for the admission of the two-phase first medium into the shell space, a tube bundle arranged in the shell space and having multiple helically coiled tubes for accommodating the second medium and a separating device for separating a gaseous phase from a liquid phase. The separating device has a tray arranged above the tube bundle which serves for collecting the liquid phase. The tray has a plurality of chimneys for separating the two phases. Each chimney projects from the tray from a side of the tray facing away from the tube bundle and is covered by a roof. An opening in the tray between the roof and an upper end of the respective chimney, there is provided an inlet opening via which the gaseous phase can flow into the respective chimney.

Separating device for coiled heat exchangers for separating a gaseous phase from a liquid phase of a two-phase medium conveyed on the jacket side

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.
