Definitions

  • the invention relates to a radiant heater with a heating tube element.
  • the heating tube element has a heating tube that is transparent or semi-transparent to infrared rays.
  • the heating tube is arranged in a focus area of a reflector having at least one focusing curvature.
  • the at least one heating tube element is arranged in a housing with at least one front side that is open or transparent or semitransparent to infrared rays.
  • Such a radiant heater is from the publication DE 39 03 540 A1 known.
  • the reflector is used to align the thermal radiation to an open front side of the housing.
  • the heating tubes used in the known radiant heaters are not described in more detail in the above publication and can have a heating element made of carbon fibers as the infrared radiator, as described in the document EP 1 168 418 B1 is known.
  • the known heating element made of carbon fibers is arranged in a quartz tube, the carbon fibers having the shape of a helix of a carbon ribbon.
  • Such a helix of a carbon ribbon made of carbon fibers has the disadvantage that it shadows the reflector over a broad band, so that the shaded area of the reflector cannot contribute to the reflection of the infrared rays in the direction of the open or infrared-transparent or infrared-semitransparent front side of the radiant heater.
  • the object of the invention is to create an improved radiant heater that makes better use of the infrared radiation from carbon fibers.
  • One embodiment of the invention has a radiant heater with a heating tube element.
  • the heating tube element has a heating tube that is transparent or semi-transparent to infrared rays.
  • the heating tube is arranged in a focus area of a reflector having at least one focusing curvature.
  • the at least one heating tube element is arranged in a housing with at least one front side that is open or transparent or semitransparent to infrared rays.
  • the housing has edges and rear sides that shield infrared rays.
  • the at least one heating tube element has a multiplicity of carbon fibers within the heating tube, which form a dimensionally stable infrared heating coil of a carbon cord, the reflector being an infrared reflector adapted to the infrared spectrum of the heating tube element.
  • This radiant heater has the advantage over a radiant heater with a heating tube element that has a carbon ribbon that the infrared reflector is less shaded, since the carbon fibers form a dimensionally stable infrared spiral of a carbon cord.
  • a carbon cord does not shade the infrared reflector in a broadband manner, since the cross-section of the carbon cord is round or circular and a spiral of a carbon cord allows larger reflective spaces between the turns of the spiral than a spiral of a carbon ribbon shading the infrared reflector over a broadband.
  • the carbon cord of the infrared heating coil can have laid, knitted, plaited, knitted or woven carbon fibers or another form of the connections between the carbon fibers.
  • the braided connection of the carbon fibers is of particular advantage, as it connects the carbon fibers to one another in a very small space and thus ensures the dimensional stability of an infrared heating coil made of a braided carbon cord reliably and for a long time.
  • the infrared heating coil in one operating state, has infrared radiation of an infrared wavelength with a maximum in a transition area between an IR-A and an IR-B.
  • a transition range is to be understood as an infrared wavelength ⁇ R between 1.2 ⁇ m ⁇ ⁇ R ⁇ 2.4 ⁇ m, so that the border of 1.4 ⁇ m between the short-wave infrared range IR-A and the medium-wave infrared range IR- B, which is indicated by the absorption line of the infrared spectrum for water molecules, is included in the transition region.
  • the position of the maximum of the infrared radiation of the infrared heating coil is ensured in this transition area because the carbon fibers of the infrared heating coil have an operating temperature T B between 1400 ° C T B 1800 ° C, preferably between 1500 ° C ⁇ T B 17 1750 ° C and more preferably between 1580 ° C T B 1620 ° C. This is explained in detail with the diagram in the appended Figure 1 explained in more detail.
  • end regions of the infrared heating coil are enclosed by metal transition elements, preferably made of nickel.
  • the metal transition elements merge into molybdenum strips, which in turn are electrically connected to through-contacts at the ends of the heating tube closed in a gas-tight manner.
  • a corresponding supply voltage of usually 100 V to 230 V can be applied to the infrared heating coil made of carbon fibers via the vias, which has the advantage over strip-shaped carbon fibers (flake) that the upstream voltage regulation, as is the case with heating elements with strip-shaped carbon fibers (flake) and Power control as required for halogen radiant heaters can be omitted.
  • the operating temperature is reached in a few seconds, preferably between 1 to 3 seconds, which is why the above-mentioned transition range of the infrared radiation according to the invention also partially protrudes into the broader range of the fast infrared medium waves of the IR-B spectrum, like it too Figure 1 made clear.
  • the heating tube has quartz glass which is transparent to infrared rays in the transition region from IR-A to IR-B and has a transparency coefficient T r of at least T r 0.99. This also means that the sum of the reflection coefficient and the absorption coefficient of the transparent quartz glass in the infrared ray transition range from IR-A to IR-B ⁇ 0.01.
  • the heating tube for infrared rays in the transition area from IR-A to IR-B has a semitransparent quartz glass with a frosted or with a particle-blasted opaque outer surface.
  • the visible part of the infrared heating coil will appear diffuse, so that the visual light component of the infrared heating coil outside the heating pipe is reduced and glare of the eyes, as is common with halogen heating elements, is prevented.
  • the absorption coefficient of the quartz tube increases slightly so that the transmission coefficient can drop to 0.90.
  • a reflective and curved surface of the infrared reflector facing the infrared spiral has reflective layers made of metal oxides, preferably Al 2 O 3 with a reflection coefficient R between 0.85 R 0.98, preferably between 0.92 R 0.98 for infrared rays with an infrared wavelength ⁇ R between 1.2 ⁇ m ⁇ R 2.4 ⁇ m in the transition region from IR-A to IR-B and up to IR-C.
  • the reflection coefficient R falls both in front of the preferred infrared wavelength range, but in the entire infrared transition wave range of interest up to the long-wave range that is used according to the invention, this high reflection coefficient R, which is adapted to the transition wave range, as it does attached diagram of the Figure 3 shows.
  • the curvature of the infrared reflector has embossed segment strips in the edge regions of the cross section, which are pressed step-by-step into a sheet of aluminum alloy with an infrared-reflecting coating.
  • embossed longitudinal beads are created between the segment strips, which generate increased dimensional stability over the entire length of the infrared reflector.
  • the segment strips support the alignment of the reflection and, on the other hand, alignment of the edge areas with the open or infrared-transparent or infrared-semitransparent front side of the housing of the radiant heater is intensified.
  • the infrared reflector is arranged directly on the heating tube and has oxide ceramic layers.
  • an oxide ceramic layer MgO, SiO 2 , Al 2 O 3 is preferably arranged on the heating tube made of quartz glass, the reflection coefficient R being in the above-mentioned range for the infrared wavelength transition range between IR-A to IR-B and up to IR-C.

  • This air convection channel advantageously ensures, on the one hand, that the housing, which partially surrounds the radiant heater or the protective tube, is cooled and, on the other hand, enables the absorbed energy of the air and moisture molecules to be released to the area around the radiant heater to be heated.
  • an air convection channel is arranged between the infrared reflector and a surrounding housing, which has openings to the surrounding air, which have different geodetic heights in mounting arrangements of the heater, over which a cooling air convection is along a curved outer surface of the infrared reflector and an inner surface of the housing spaced apart from the outer surface.
