Title: FLOW PLATE FOR A HUMIDIFIER
Abstract:
The invention relates to a flow plate (22; 47; 52) for a humidifier (1), having flow fields (28, 29) on both mutually opposite flat sides (21, 27) of the flow plate (22; 47; 52). Humidifiers of this kind are used in particular for humidifying process gas for an electrochemical system or in HVAC applications. Conventional humidifiers have lower power since an exchange of humidity usually takes place only between the layers immediately adjacent to the water exchange membranes. The flow plate proposed here has a multiplicity of through-openings (40, 48), wherein the through-openings (40, 48) are designed such that a perpendicular projection of the through-openings (40, 48) onto a plane oriented parallel to the plane of the flat surface of the flow plate (22; 47; 52) has a non-vanishing area, so that gas passing through the through-openings (40, 48) effects, at least in part, mixing of gas guided in the flow fields (28, 29) perpendicular to the plane of the flat surface of the flow plate (22; 47; 52). The through-openings (40, 48) improve the power of the humidifier, thus permitting a lower number of flow plates and therefore a more lightweight and more compact design.
