HUMIDIFYING DEVICE HAVING CHANNEL PLATES AND CHANNEL PLATE FOR HUMIDIFYING DEVICE

A humidifying device has a plate stack with channel plates stacked in stacking direction in the plate stack. The channel plates have a longitudinal axis perpendicular to the stacking direction. One or more channel plates have a first and a second channel partial plate arranged on each other in stacking direction, and each provided with a circumferentially extending frame and stays arranged between oppositely positioned sides of the frame. The stays are slanted to the longitudinal axis. The stays of the first and second channel partial plates cross each other, viewed in the stacking direction. Semipermeable layers separate a first group of flow channels and a second group of flow channels from each other in the plate stack. Flow channels of the first group alternate with flow channels of the second group in the stacking direction. The first or second group of flow channels extends along the longitudinal axis.
