Abstract
A humidifying module that includes a plurality of hollow fiber membranes grouped together to form a hollow fiber membrane bundle. A moisture exchange is performed through a thickness of each hollow fiber membrane between fluid streaming within an interior of each hollow fiber membrane and along an exterior of each hollow fiber membrane. An inner flow passage is inserted within the hollow fiber membrane bundle and along a longitudinal axis thereof, wherein a total longitudinal length which the inner flow passage is inserted within the hollow fiber membrane bundle is shorter than a longitudinal length of the hollow fiber membrane bundle. The inner flow passage includes an inlet and an outlet through which the fluid passes. An end wall is located proximate the outlet. A protrusion is disposed at the end wall and opposite a flow direction of the fluid streaming within the inner flow passage.
