Abstract: The invention relates to a heat exchanger for indirect heat exchange between a first medium and a second medium, comprising a shell surrounding a shell space which extends along a longitudinal axis. The shell space serves for accommodating the first medium. A tube bundle is arranged in the shell space having multiple tubes for accommodating the second medium. The tubes are helically coiled in multiple tube layers onto a core tube. The tube bundle has a multiplicity of inner tube layers, surrounding the core tube, and a multiplicity of outer tube layers, surrounding the inner tube layers. The heat exchanger discharges a part of a gaseous phase out of the shell space from the region of the inner tube layers via a gas discharge device, and/or supplies a gaseous phase into the shell space in the region of the outer tube layers via a gas supply device.

Abstract: A heat storage device for transferring heat indirectly between a fluid and a heat storing medium, and for storing transferred heat, includes a container that surrounds an interior of the container, the heat storing medium being located in this interior. A plurality of vertical tubes are arranged in the interior of the container, each of these tubes being fluidically connected to a vertical header tube by means of a lower end section. Each of the tubes has a plurality of heat transfer fins that contact the heat storing medium.

Abstract: A method for adhesively bonding a first component to a second component, the two components being bonded, for preliminary fixing, with a first adhesive to form a first adhesive bond, and the two components being bonded, for producing an elastic second adhesive bond, with a second adhesive. The first adhesive bond after the second adhesive bond has been cured is stressed in such a way that it is destroyed so the second adhesive bond is elastically deformable unhindered by the first adhesive bond. An assembly produced in such a way is also described.
