Patent number: 11631869Abstract: A flow plate for a humidifier, having flow fields on both mutually opposite flat sides of the flow plate is described. The flow plate proposed here has a multiplicity of through-openings, wherein the through-openings are designed such that a perpendicular projection of the through openings onto a plane oriented parallel to the plane of the flat surface of the flow plate has a non-vanishing area, so that gas passing through the through-openings effects, at least in part, mixing of a gas guided in the flow fields perpendicular to the plane of the flat surface of the flow plate. The through-openings improve the power of the humidifier, thus permitting a lower number of flow plates and therefore a more lightweight and more compact design.Type: GrantFiled: September 22, 2017Date of Patent: April 18, 2023Assignee: REINZ-DICHTUNGS-GMBHInventors: Rainer Glueck, Andre Speidel
