  • Publication number: 20180054856
    Abstract: An irradiation device for introducing infrared radiation into a vacuum processing chamber has an infrared emitter capped on one end and including an emitter casing tube in the form of a round glass tube, of which a closed end projects into the vacuum processing chamber. A vacuum feedthrough holds the emitter casing tube and leads it in a gas-tight manner through an opening of the vacuum processing chamber. A heating filament and a current return are arranged in the emitter casing tube, wherein the heating conductor has, in the section of the emitter casing tube surrounded by the vacuum feedthrough, a connection element that is led out from the emitter casing tube. The connection element of the heating conductor is guided through a tube section and the return conductor has, in the section of the emitter casing tube surrounded by the vacuum feedthrough, a means for compensating for thermal expansion.

  • Publication number: 20040217111
    Abstract: The invention relates to an infrared radiation source having at least one electrical heat conductor situated in a long, two-ended casing tube made of quartz glass, the casing tube having at least one elevation made of quartz glass on its wall which faces the at least one heat conductor, which locally reduces the inner diameter of the casing tube. At least one heat conductor is designed as a heating coil. The casing tube has a constant outer diameter in the region of the heating coil, the elevation has a convex shape on its surface facing the heating coil, and the heating coil contacts the elevation only at the highest point of the elevation.

  • Patent number: 6765339
    Abstract: An infrared lamp with a closed-off enveloping tube which encloses an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of a long axis of the enveloping tube, determines an irradiation length of the infrared lamp in the sense of a higher irradiation output. The carbon ribbon has a length which is larger than the irradiation length by a factor of at least 1.5. With a procedure for heating a material to be processed using the infrared lamp, which makes possible short processing times in connection with a simultaneous high degree of energy efficiency, the infrared lamp may be operated such that its maximum emission lies within a wavelength range from 1.8 &mgr;m to 2.9 &mgr;m, and such that its power output comes to at least 15 Watts per cm3 of the volume enclosed by the enveloping tube over the irradiation length.

  • Patent number: 6591062
    Abstract: The invention relates to an infrared radiator with a heating element containing carbon fibers disposed in a quartz glass tube, with its ends connected to contact elements running through the wall of the quartz glass tube. The known radiators are improved by the fact that the heating element is spaced away from the wall of the quartz glass tube and it is centered on the axis of the quartz glass tube by means of spacers. The invention furthermore relates to a method by which the infrared radiator is operated at heating element temperatures greater than 1000° C.

  • Patent number: 6577816
    Abstract: A radiation system has at least two elongated envelope tubes permeable to light and infrared radiation which are joined together and sealed from the ambient atmosphere, a first envelope tube of which contains an incandescent coil which is electrically connected through sealed tube ends and external contacts to an external power supply and emits infrared radiation in the near IR range; furthermore, at least a second envelope tube is provided which has an elongated carbon strip as an infrared radiator for radiation in the medium IR range, which is likewise connected through sealed ends and external contacts with the external power supply or with an additional external power supply. Preferably a carbon strip is used as the radiator strip, which is configured either as an elongated coil or forms an elongated strip.

  • Patent number: 6464918
    Abstract: In the production of spiral-shaped heating elements, a device winds an oblong base material onto a mandrel while forming a spiral with the base material and equips the ends of the spiral with contacts for electrical connection. The device includes a feeding device for supplying the mandrel, onto whose casing surface the base material is wound in a spiral shape, with the oblong base material. In order to carry out a method for the production of a spiral-shaped heating element made of material containing carbon fibers, the method is as follows: utilize a base material that comprises carbon fibers which have been embedded into IBM a thermoplastic embedding compound, heat the base material to a temperature at which the embedding compound softens, wind the softened base material onto the mandrel while forming the spiral, and set the spiral shape by removing the embedding compound.
