Gas exchange unit comprising an inlet that is acentrically slanted, and a method for producing a gas exchange unit.

Gas exchange unit

The invention relates to a method for producing a device for material exchange between two mediums, in which at least one mat of semipermeable hollow fibres () is wound onto a winding core (), which has at least one core opening () in its outer surface for a first in- or out-flowing medium, and the winding core () is arranged in an axially extending housing () having at least one housing opening () for the first in- or out-flowing medium, and the axial end regions of the housing () are sealed by an adhesive () arranged around the hollow fibres (), wherein at least one chamber region () surrounding the hollow fibres () is formed via the adhesion between the axial end regions () of the housing () and between the winding core () and the housing (), through which chamber region the first medium can flow via the core opening () and the housing opening (), wherein the axial distance between the core opening () and the housing opening () is adjusted to a desired value of multiple possible values via the axial shifting of the winding core () relative to the hollow fibre winding () arranged around the winding core () and relative to the housing (), and the hollow fibres () are adhered to the side of the housing () near to the housing opening () in a region between the axial end surface of the housing and the housing opening (), and the hollow fibres () are adhered to the side of the housing () near to the core opening () in a region between the axial end surface of the housing and the core opening (). The invention also relates to a number of multiple devices for material exchange between two mediums, wherein all devices comprise at least identical housings () and winding cores () that are identical at least in regions.
