A lamellar arrangement for shielding radiation acting on a fluid which flows through an interior of a device, comprises two or more lamellae aligned substantially parallel to one another and respectively defining an intermediate space between them, wherein at least one subset of the lamellae is respectively subdivided into at least three lamella sections comprising a first lamella section, a second lamella section next to the first lamella section and a third lamella section next to the second lamella section. The first lamella section and the second lamella section in this case enclose a first angle between them, and the second lamella section and the third lamella section enclose a second angle between them. The first angle has a magnitude in a range of from 20° to 45° and the second angle has a magnitude in a range of from 20° to 45°.

Lamellar arrangement and device for sterilizing a fluid by means of UV radiation comprising such a lamellar arrangement

Disclosed herein is a cooling device, comprising a cooling plate and a cooling cap, for cooling a heat source, mounted to an outer interface surface of the cooling plate, by means of a cooling fluid. Several spiral-shaped fins are integrated into the cooling plate to form a structure in the shape of a multi-spiral. The fins are arranged next to each other in a mutual distance to form spiral-shaped flow channels for a cooling fluid. An inlet for inflowing the cooling fluid at the center of the multi-spiral fins structure is integrated into the cooling cap. The cooling cap is configured and arranged on the cooling plate so that the inlet is positioned above the center of the multi-spiral fins structure.

Cooling device for cooling by means of a cooling fluid

A lighting device that illuminates textiles by optical waveguides includes a body that receives the optical waveguide; a clamping device for the received optical waveguide; and a lighting module, wherein the lighting module is arranged within the body to enable light emitted by the lighting module during operation to be coupled into the optical waveguide, and the clamping device is adapted to repeatedly clamp and release the optical waveguide.
