Abstract: A plate for a heat exchanger wherein the plate is an at least two-layer flat laminate having a rigid, nonplanar, and three-dimensional support that consists of a broken-through and plastically deformable material and a flat membrane layer that transfers enthalpy between two fluid streams separated by the plate. A flat surface connection between the membrane layer and the support layer ensures that the support provides the plate with a predetermined mechanical strength and a three-dimensional shape.

Abstract: A rotary heat exchanger through which a first fluid flow—an outside air or inlet air flow, for example—and a second fluid flow—an exit air or outgoing air flow, for example—can flow in a counterflow configuration, has a rotatably mounted rotor (5) that has a first flow sector for the first fluid flow and a second flow sector for the second fluid flow through which the rotor (5) passes during a rotation, a frame in which the rotor (5) is rotatably supported, and a sealing assembly (9) by means of which an inflow side of the first fluid flow and an outflow side of the second fluid flow can be separated from the outflow side of the first fluid flow and from an inflow side of the second fluid flow, respectively.

Abstract: The invention relates to a cross-flow plate heat and/or moisture exchanger having plates which are arranged above, below or next to one another, and form alternating flow passages for a first and a second fluid. According to the invention, for a cross-flow plate heat and/or moisture exchanger of this type, in order to achieve an improved transfer performance and an increased pressure stability in relation to differential pressures between the two fluids, each plate (2) has a first cross-flow region (4), a following counter flow region (6) in the flow direction of the first cross-flow region (4), and a following second cross-flow region (10) in the flow direction of the counter flow region (6).

Abstract: A plate element (1) for a heat exchanger is designed as an at least two-layered laminate assembly (1). Said laminate assembly (1) includes a membrane layer (2) which allows enthalpy between two fluid flows separated by the plate element (1) to be transferred, and at least one support layer (3, 4) which is made of a broken-through, deformable material and which allows the plate element (1) to be provided with a given mechanical rigidity and three-dimensional structure and maintain said rigidity and structure.

Abstract: The invention relates to a heat and/or moisture exchange element, such as a heat and/or moisture exchange plate for plate heat and/or moisture exchangers, a storage mass layer for rotation heat and/or moisture exchangers and the like, wherein a greater and more precisely adjustable efficiency in transferring thermal energy and/or moisture is enabled without noticeable increase to the technical design complexity for production. According to the invention, the heat and/or moisture exchange element is designed from a structure penetrated by a plurality of hollow points and designed to be selectively permeable to water and water vapor and/or capable of storage.
