  • Publication number: 20240145740
    Abstract: A humidifier has a housing with inlet and outlet for a first fluid and inlet and outlet for a second fluid. A plate stack with channel plates sequentially arranged in a stacking direction is arranged in the housing. The channel plates have flow channels for the first and second fluids, respectively, separated by semipermeable membranes. The plate stack has a first end plate arranged at a first end and a second end plate arranged at a second end, wherein the first and second ends face away from each other in stacking direction. The housing has a receiving device interacting with a counter receiving device at the plate stack for supporting and sealing the plate stack in the housing. The counter receiving device extends in a plane normal to the stacking direction and is arranged at the first or second end plate. A plate stack for the humidifier is provided.

  • Publication number: 20240145741
    Abstract: 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.

  • Patent number: 6805089
    Abstract: An intake device (1) for an internal combustion engine including a main body (2) and cover element (3; 20) which are securely connected to one another. Main body (2) and cover element (3) form intake pipes (4, 5, 6, 7) of in intake manifold. The cover element (3; 20) includes a plurality of individual shells (14, 15, 16, 17; 24, 25, 26, 27), which are connected to one another. Each individual shell (14, 15, 16, 17; 24, 25, 26, 27) forms a wall section of a respective intake pipe (4, 5, 6, 7) of the intake device (1). A flexible connection element (22) is arranged between two successively adjacent individual shells (25, 26) to compensate for tolerances between the cover element (3) and the main body (2).
