  • Radiator units of this type are used, for example, as individual radiators or as individual elements for infrared surface radiators, which are used for heating, drying or curing large-area material or goods which move past the surface radiator in a continuous process.
  • radiator units which have medium-wave quartz glass infrared radiators in the form of so-called twin tubes, the ends of the twin tubes being open at the front and open on both sides by means of their end faces attacking, at the same time serving as an end plate holding bases are fixed on a mounting surface.
  • Each holding base is designed in the form of an angle, one leg of which has a slot running parallel to the underside of the leg, and the upper side of the leg of the other leg has an elongated recess.
  • the holding bases are plugged on opposite ends of the mounting plate on both sides and thereby form together with this a holding frame for the infrared radiators, these being held between two holding bases and being received with their end faces by the elongated recesses of the holding base.
  • the mounting frames are provided with retaining screws, on which the mounting base is fastened by means of a wing nut and a spring that is resistant to high temperatures, from the back of the mounting frame facing away from the heated material, and which are to be detached for mounting and removing the individual infrared radiators.
  • the electrical connections for the heating coil of the individual infrared heaters are led out in the form of two insulated cables on a common end face of the twin tube, bent through 90 ° in the direction of the mounting frame and threaded through two grooves in the holding base, which correspond to the corresponding holes in the holding frame, and to the rear of the Mounting frame led out from where they are connected to the power supply.
  • the electrical connections must be removed and relocated when the new infrared heater is installed.
  • a plurality of infrared radiators running parallel to one another and having a length adapted to the dimensions of the mounting frame can optionally be attached to a mounting frame.
  • surface emitters can be built whose radiation surfaces are adapted to the material to be irradiated.

  • these standard radiator units it is possible in the sense of a modular system to change the geometry of surface radiators and adapt them to the heating material, although the smallest possible geometry change is determined by the dimensions of the smaller mounting frame.
  • the mounting frame together with the infrared radiators must be detached from one another and reassembled in the desired arrangement.
  • the wall thickness of the holding base seen in the direction of the longitudinal axis of the infrared radiator, is relatively large, since on the one hand a certain insulating distance is required to avoid flashovers between adjacent current-carrying parts, and on the other hand the bending of the electrical connections within the holding base must not be less than a minimum radius of curvature , otherwise the connection wires would kink.
  • relatively long unheated zones are formed on the end faces of the infrared radiators in the known radiator units, which are particularly noticeable when the radiator units are joined together in the form of a straight joint at the joints, in the sense of an inhomogeneous temperature profile at these points.
  • the present invention is therefore based on the object of specifying an inexpensive and reliable radiator unit which allows simple assembly and disassembly and a variable arrangement of the infrared radiator and which can be used to produce flat radiators with the shortest possible unheated zones.
  • the receiving elements are designed as continuous mounting holes and are arranged in the form of a grid which is formed from a basic pattern with at least three-fold symmetry in that the bases have at least one mounting element, that is designed as a perpendicular to the plane of the mounting plate, continuous mounting hole for receiving a fastening element anchored in a mounting hole for the base, that the base associated with the one end piece has at least one connection hole, which is designed as a through hole and in relation to the at least one mounting element is arranged so that it is compatible with this as well as together with the at least one mounting element of the base assigned to the other end piece with the grid, that the end pieces are detachably connected to the respective assigned base, and that the electrical connections in the form of two Connection pins are led out of the at least one end piece, the free ends of which protrude at right angles to the longitudinal axis of the quartz glass tube and form an electrical contact with a power supply in the at least one connection hole of the respective one extend end piece associated with the base.

  • compatible should be understood to mean that with a certain arrangement of the base or the two bases assigned to the end pieces of an infrared radiator on the mounting plate, all mounting elements and connection bores can be brought into register with one another with mounting bores of the mounting plate.
  • This configuration of the mounting plate and base enables the arrangement of an infrared radiator held on the bases to be adapted in a simple and flexible manner to the material to be heated or other requirements. An assembly or disassembly of the mounting plate is not necessary for this.

  • Mounting plates on which the mounting holes have the same diameter and in the form of a grid have proven to be particularly advantageous are arranged with a square basic pattern.
  • This basic pattern enables the base mounted on the mounting plate to be rotated by 90 ° or an integral multiple thereof.

  • a radiator unit has proven to be particularly simple and inexpensive to manufacture and can be used variably, in which the base is provided with four through holes arranged in a square to one another, two adjacent holes each of which are designed as connecting holes and two adjacent holes are each formed as fastening holes.
