Stack plate, stack plate device and humidifier

Abstract

A stack plate of a stack plate device of a humidifier includes inlay parts extending along two opposing front and/or two opposing longitudinal ends of the stack plate, a semi-permeable layer disposed on and supported by the inlay parts, and a frame disposed on the semi-permeable layer supported by the inlay parts, the frame circumferentially enclosing a through-opening in the stack plate. A remaining portion of the semi-permeable layer covers the through-opening. An outer circumferential section of the semi-permeable layer and the inlay parts are embedded within an over-molded portion of the frame. Opposing front ends of the frame define inflow and outflow regions, respectively, on a first side of the frame for a second fluid, and opposing longitudinal ends of the frame define inflow and outflow regions, respectively, on a second side of the frame for a first fluid.
