Definitions

  • the invention relates to a tubular heating element, consisting of a support tube made of metal, which has in its outer surface one or more thread-like grooves with different pitches in individual axial regions, in which flexible provided with at least one Schudraht Maisl Rohrrichpatronen, which form a cartridge spiral, inserted and / or are pressed in, such that their electrical connections protrude from the carrier.
  • WO 2002/096156 A1 discloses a heating element having an outer reflector tube in which a heating element having at least one resistance wire is arranged substantially coaxially, which can be connected to a power source via end connections and which is fastened in a holding section on the inner wall of the reflector tube.
  • the invention has for its object to provide a tubular heating element which can be acted upon in sections with different heat outputs and in which a plurality of independently switchable Schudrahtchtln can be installed in a confined space to provide high heat outputs on a support tube.
  • the heating element consists of a support tube 1 made of brass, copper or the. Like., The lateral surface is provided with thread-like grooves 2 and 3, which respectively begin at the ends 4 and 5 of the support tube 1. How out Fig. 1 It can be seen that the turns of the grooves 2 and 3 in the end regions of the support tube are each guided closely juxtaposed while they have towards the center of the support tube towards greater distances or a greater slope. In these grooves 2 and 3 are each separate Pipe heater cartridges 6 and 7 inserted or pressed, the closed ends 8 and 9 respectively in the initial region of the grooves 2 and 3 and thus also in the vicinity of the carrier pipe ends 4 and 5 are.
  • the two terminal ends 10 and 11 of the two Rohrrichpatronen 6 and 7 are guided radially from the support tube 1 to the outside.
  • the ends 14 and 15 or 16 and 17 are respectively connected to connecting leads 18, 19 or 20 and 21.
  • Fig. 3 are the ends of the Schudrahtwicklitch the two Rohrrichpatronen 6 and 7 within a connection sleeve 12 'according to Fig. 5 interconnected with each other.
  • Fig. 4 How out Fig. 4 can be seen, are in the metal shells 22 and 23 of the two Rohrrichpatronen 6 and 7 respectively in two parallel helical strands 24, 25 and 26, 27 extending Bankdrahtplanetaryln 28 and 29 embedded in a conventional manner in an insulating 30 and in these are pressed.
  • terminals 31, 32 and 33, 34 are not interconnected but each separately connected to a voltage source and also separately switched on and off.
  • each one Wiendrahtende 35 via a Connecting wire 35 'connected to the strand 18 and the Schwarzdrahtende 36 of Walkerdrahtplanetaryl 29 is connected via a connecting wire 36' to the pigtail 21.
  • the other two Schwarzdrahtenden 38 and 39 are connected via connecting wires 40 and 41 by a clamping sleeve 42 with each other.
  • tubular heating cartridges which have two or more heating wire coils instead of just one heating wire coil, it is of course possible to provide more different electrical circuits and controls of the individual heating wire coils in order to meet different performance requirements.
