1. A hollow fiber module of a device for separating fluids, the module comprising: hollow fibers comprising walls that are comprised of partially permeable structures, the hollow fibers positioned parallel to each other;at least one areal fluid-permeable spacer medium comprising a structure that is self-supporting an areal state of the at least one spacer medium;the at least one spacer medium arranged between the hollow fibers such that the at least one spacer medium surrounds at least partially circumferentially a first one of two neighboring hollow fibers at least on a side of said first hollow fiber that is facing the second one of the two neighboring hollow fibers;wherein a first spacer medium of the at least one spacer medium is an air permeable mat of open, flexible material;wherein the mat is corrugated to form a continuous corrugated mat having a plurality of alternating corrugation valleys and corrugation peaks, the corrugation valleys opening at a first side of the corrugated mat and the corrugation peaks opening at an opposing second side of the corrugated mat;wherein a first portion of the hollow fibers are arranged directly on the corrugated mat in corrugation valleys opening at the first side of the corrugated mat;wherein a second portion of the hollow fibers are arranged directly on the corrugated mat in immediately adjacent corrugation peaks opening in the opposing second side of the corrugated mat, such that individual ones of the hollow fibers are arranged alternatingly in the corrugation valleys and corrugation peaks at opposite sides of the corrugated mat to form a hollow fiber layer. 2. The hollow fiber module according to claim 1, further comprising at least one fixation element, wherein the hollow fibers are fixed on the mat by the at least one fixation element. 3. The hollow fiber module according to claim 2, wherein the at least one fixation element is a fixation element strip extending transversely to the corrugations;wherein the fixation element strip is arranged directly on and extending traversely to corrugation peaks, connecting adjacent corrugation peaks across interposed corrugation valleys;wherein the fixation element strip directly contacts hollow fibers arranged in the corrugation valleys between the corrugation peaks to fix the hollow fibers to the spacer medium. 4. The hollow fiber module according to claim 2, wherein several of said hollow fiber layer are arranged in a layered configuration. 5. The hollow fiber module according to claim 4, wherein the mats of said several hollow fiber layers are arranged such that the hollow fibers of a first one of said hollow fiber layers, in a viewing direction perpendicular to a plane defined by longitudinal axes of the hollow fibers of said first hollow fiber layer, are arranged between two hollow fibers, respectively, of a second one of said hollow fiber layers that is neighboring said first hollow fiber layer. 6. The hollow fiber module according to claim 4, further comprising a spacer element arranged at least between two of said hollow fiber layers that are neighboring each other. 7. The hollow fiber module according to claim 1, wherein several of said hollow fiber layer are arranged in a layered configuration. 8. The hollow fiber module according to claim 7, wherein the mats of said several hollow fiber layers are arranged such that the hollow fibers of a first one of said hollow fiber layers, in a viewing direction perpendicular to a plane defined by longitudinal axes of the hollow fibers of said first hollow fiber layer, are arranged between two hollow fibers, respectively, of a second one of said hollow fiber layers that is neighboring said first hollow fiber layer. 9.
