Abstract: A hollow fiber module is disclosed. The hollow fiber module in various aspects of the present invention may include: a housing, and a hollow fiber bundle mounted in the housing and having a fluid penetration distance ranged from 10 to 200 mm. The fluid penetration distance means the shortest distance from the outmost hollow fiber in a cross-section of the hollow fiber bundle to the hollow fiber existing at the center in the cross-section of the hollow fiber bundle. In accordance with various embodiments of the present invention, the hollow fiber module may maximize the fluid delivery efficiency by improving the flow uniformity of the fluid flowing the outside of the hollow fibers. In addition, the hollow fiber module may minimize the additional usage of the hollow fibers, and thus the cost and the size of the hollow fiber module may be reduced.

Abstract translation: 公开了一种中空纤维模块。 本发明的各个方面的中空纤维组件可以包括：壳体和安装在壳体中的中空纤维束，其流体穿透距离为10-200mm。 流体穿透距离是指在中空纤维束的横截面中最外侧的中空纤维与存在于中空纤维束的截面中心的中空纤维的最短距离。 根据本发明的各种实施例，中空纤维模块可以通过改善流过中空纤维外部的流体的流动均匀性来最大化流体输送效率。 此外，中空纤维模块可以最小化中空纤维的额外使用，因此中空纤维模块的成本和尺寸可能会降低。
