In this case, not only is there a short-circuit flow of radially flowing blood, which is able to flow directly from the inside of the cylinder to its inner wall without substantially entering into interactive mass transport with hollow fibers; moreover, in this configuration Significant wall effects between the hollow fiber mat and the inner wall of the cylinder can also sometimes occur in the mold, thereby greatly reducing the desired mass transport

Embodiment Construction
[0048] In the following description, the same reference numerals are used for the same components or components having the same effect.
[0049] figure 1 A schematic cross-sectional view of a first embodiment of a hollow fiber bundle 1 according to the invention is shown, comprising a total of three different sets of hollow fiber strands 10a, 10b and 10c, the respective preferential directions V1, V2 and V3 are independent of each other. The preferential directions are specifically arranged such that the first set of hollow fiber strands 10a has a preferential direction V1, the second set of hollow fiber strands 10b has a preferential direction V2, and the third set of hollow fiber strands 10c has a preferential direction V3. For a clearer depiction, only two hollow fiber strands 10a (each of which is formed by two hollow fibers 11 ) and only two hollow fiber strands 10b (each of which is similarly formed by two hollow fibers 11 ) are illustrated form). The two hollow fiber...

The invention relates to a hollow fiber bundle (1) for accommodation in a mass transport device, said hollow fiber bundle comprising a plurality of hollow fiber strands (10a, 10b, 10c) for heat transport and / or mass transport, The plurality of hollow fiber strands (10a, 10b, 10c) are at least locally aligned substantially along a preferential direction and arranged relative to each other with respect to their local preferential direction such that at least one hollow fiber strand of the first group is substantially aligned along a first preferential direction (V1), at least one second group of hollow fiber strands directed substantially in a second preferential direction (V2), and at least one third group of hollow fiber strands directed substantially in a third preferential direction (V3), said three preferential directions independent of each other.
Description
technical field [0001] The invention relates to a hollow fiber bundle for accommodation in a mass transport device, to a mass transport device for accommodation of at least one such hollow fiber bundle and to a method for producing a hollow fiber bundle for accommodation in a mass transport device. Background technique [0002] The fields of use of substance transport devices range from general industrial applications in chemistry or physics to applications in medical technology. A substance transport device according to the invention involves the transport of a substance, which may be present in a gas phase or even a liquid phase, between a first phase and a second phase which is connected to the first phase by a permeable membrane. isolation. In this case, species transport is ensured due to the concentration or pressure gradient between the first and second phases. Depending on the substances exchanged and accordingly the phases these substances assume, the configuratio...
