Abstract:
An IR radiant heater has at least one planar carbon heating element (1) arranged in a housing, which is transparent or at least partially transparent to IR radiation. At least one carbon heating element (1) is a carbon fiber-reinforced carbon (CFC) web arranged in a plane and arranged between two plates (2, 3), of which at least one is transparent or partially transparent.
Abstract:
An infrared device is provided, in particular an infrared radiation heating device having an infrared radiator for the heating of devices exposed to weather. The infrared device includes an emitter, wherein the emitter for radiating the infrared radiation is inserted in a housing, and the emitter is protected on the emitting side by a protection unit for the emitted radiation. The infrared radiator, the inner housing wall, and the unit are arranged such that cooling takes place by natural convection. A method is also provided for operating such a device in a wind turbine.
Abstract:
In a known component having a reflector layer, the surface of a base body of quartz glass is covered at least in part with a reflector layer. Starting from this, to provide a component, particularly for use in lamp and reflector manufacture, which is equipped with an efficient, chemically and thermally resistant and, nevertheless, inexpensive reflector layer, it is suggested according to the invention that an SiO2 cover layer should be provided which acts as a diffuse reflector and consists of at least partly opaque quartz glass.

Starting from this, to provide a component, particularly for use in lamp and reflector manufacture, which is equipped with an efficient, chemically and thermally resistant and, nevertheless, inexpensive reflector layer, it is suggested according to the invention that an SiO2 cover layer should be provided which acts as a diffuse reflector and consists of at least partly opaque quartz glass. The method of the invention for producing such a component is characterized in that a slip which contains amorphous SiO2 particles is produced and applied to the surface of the base body with formation of a slip layer, the slip layer is dried and then vitrified with formation of an SiO2 cover layer.
