The invention relates to a wound heat exchanger having a core tube extending along a longitudinal axis in an axial direction and having a tube bundle, which has a plurality of tubes for conducting a first fluid, wherein the tubes are wound about the core tube in a plurality of windings, the tubes being arranged in a radial direction perpendicular to the axial direction in a plurality of tube layers, adjacent windings of at least one tube layer having different axial distances in the axial direction and/or tube layers adjacent in the radial direction having different radial distances from each other in a cross-sectional plane perpendicular to the longitudinal axis. The invention further relates to a method for producing a wound heat exchanger and to a method for transferring heat between a first fluid and a second fluid by means of the heat exchanger.

Wound heat exchanger, method for producing a wound heat exchanger and method for exchanging heat between a first fluid and a second fluid

A heat exchanger includes a core tube extending in a shell space, several tubes wound around the core tube, and a liquid distributor. The liquid distributor is arranged above the tubes in the shell space and applies a liquid phase of a first medium to the tubes. The liquid distributor has distributor arms projecting in the radial direction from the core tube, an annular channel extending above the distributor arms in a circumferential direction of the shell and a collector tank formed by the core tube. The annular channel and the collector tank are each designed to collect the first medium. The distributor arms form at least one first container and at least one second container separated from the first container.

Controllable liquid distributor of a coiled-tube heat exchanger for realizing different liquid loadings

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.
