Definitions

  • the invention relates to an infrared radiator with an elongated, gas-tight cladding tube Quartz glass and arranged in the cladding heating element made of carbon, wherein the heating conductor electrically connected to at least two electrical contacts outside the cladding tube and wherein the heating conductor by at least one spacer made of carbon spaced from the cladding tube and centered therein, the heating conductor being elongated Band is formed.
  • the invention further relates to the use of such Infrared radiator and a method for its production.
  • Infrared radiators of the type mentioned are known from US 6,057,532.
  • the heating element is in a cladding tube made of quartz glass by means of spacers Carbon fiber centered and spaced from the wall of the cladding tube.
  • a spacer On the one hand, a yoke is used, which on nubs, which on the inner wall of the cladding tube are molded, is fixed. The preparation of the yoke itself and the molding of the Nubs on the inner wall of the cladding tube is very expensive and therefore expensive.
  • spacers are used in the form of a splint, which by the band-shaped heating element inserted and fixed again in the cladding tube by means of knobs.
  • the at least one spacer is formed as a disc, wherein the disc has an opening for the passage of the heating element, wherein the disc at least partially fills the open cross section between the heating conductor and the cladding tube.
  • Such spacers are easy to manufacture and mount in the cladding tube. A perforation of the heating element itself is not required and a structuring of the inner wall of the cladding tube before introducing the spacer in the pipe cross section is no longer required.
  • the disc is formed of carbon fiber reinforced carbon (CFC).
  • CFC carbon fiber reinforced carbon
  • the opening comprises part of the circumference of the disc.
  • the heating element has to be threaded through the pane be, which means a higher installation time.
  • the disc has a thickness in the range of 0.5 to 5 mm.
  • the heating conductor material used is graphite, graphite foil or carbonized, graphitized CFC material preferred for use.
  • heating element is glued in the opening, allowing a hiking of the Heating conductor is prevented in the disc. After bonding of heating conductor and disc takes place a heating of volatiles from the adhesive used.
  • the cladding tube is an oval perpendicular to its longitudinal axis Cross section has.
  • a cladding tube which is perpendicular to its longitudinal axis a circular cross-section has, it is advantageous if in the region of at least one spacer the cladding tube is deformed. A change in the wall thickness of the cladding tube is thereby substantially not generated.
  • an infrared radiator which has a cladding tube with a circular cross-section, is made such that the heating element is pushed together with the at least one spacer in the cladding tube and then the cladding tube is deformed by the cladding tube in Temperature is applied to the region of the at least one spacer and the heated cladding tube is deformed such that the at least one spacer fills the open cross section between the heating conductor and the cladding tube.
  • Such a method is simple, fast and inexpensive to perform, with a weakening of the cladding does not occur. Only an exposure of the cladding tube with temperature leads to a collapse of the cladding tube inner diameter and an adaptation to the at least one spacer.
  • the heated quartz glass can also be deformed via possibly heated dies.
  • Figure 1a shows a spacer 1, which is formed as a disc, wherein the disc has an opening 2 for carrying out a heat conductor.
  • the disc is made of carbon fiber reinforced Carbon (CFC) is formed.
  • FIG. 1b shows the spacer 1 from FIG. 1a in a side view. It is through the opening 2, visible in Figure 1a, a heating element 3 out.
  • FIG. 1 a time a further spacer 1 made of carbon fiber reinforced carbon (CFC), at the opening 2 is a part of the circumference of the disc designed as a spacer. 1 includes.
  • CFC carbon fiber reinforced carbon
  • Figure 2b shows the spacer 1 of Figure 2a in the side view, wherein in the opening of the second a heating conductor 3 is arranged.
  • FIG. 3 shows the cross section through an infrared radiator with a cladding tube 4 serving as a twin tube is designed with oval cross-section and consists of quartz glass.
  • a heat conductor 3 is arranged, which by disk-shaped spacers 1 is centered and held.
  • the heating element 3 are located in the openings 2 of the spacers 1.
  • Figure 4a shows a longitudinal section through an infrared radiator with a cladding tube 4, which has a circular cross-section.
  • a heating element 3 is arranged, the is centered and held by spacers 1 in the cladding tube 4.
  • the ends of the cladding tube 4 are sealed gas-tight and have current feedthroughs 5a, 5b.
  • the heating element 3 is over tensioned a tension spring 6, so that prevents heating of a sagging of the heating element becomes.
  • FIG. 4b shows the infrared radiator from FIG. 4a in a further longitudinal section, which is rotated 90 ° is made to represent in Figure 4a.
  • FIG. 5 shows a cross section through an infrared radiator with a cladding tube 4, which has a having circular cross-section.
  • a heating element 3 is arranged, which by spacers 1 is centered and held in the cladding tube 4. In this case, the heating element 3 through an opening 2 out in the spacer 1.
  • the spacer 1 is designed as a non-circular disk, the velvet heating 3 is introduced into the cladding tube. Only then is the cladding tube 4 in Area of the spacer 1 is heated and deformed, so that a local adjustment of the inner contour of the cladding tube 4 and the spacer 1 in the areas 4a, 4b of the cladding tube 4 is generated. As a result, a rotation of the heating element 3 in the cladding tube 4 is effective prevented and the cladding tube 4 not weakened.
