Definitions

  • the present invention relates to a radiator module, in particular an infrared radiator module, with a box-shaped housing which has a rear wall and flat side walls running perpendicular to the rear wall and which is constructed in each case mirror-symmetrically to each of two planes perpendicular to the rear wall and perpendicular to one another, wherein a preferably trough-shaped reflector part is inserted into the housing from the open housing side opposite the rear wall, the reflector part having at least two opposite edges of the reflector edge parts bent outwards, the edge parts of the side walls assigned to these edge parts and directed towards the inside of the housing, rest, one or more emitters being arranged in front of the reflector trough as seen from the open housing side, and the housing having connecting elements by means of which it can be fixed in place.
  • radiator modules are, for example, from the product information "Medium-wave tripod and hand-held infrared heaters INFRADRY from Heraeus Quarzschmelze GmbH (QD 1/146, 5C 5.85 / N Ku) and the product information Medium-wave kit infrared heaters MBS from Heraeus Quarzschmelze GmbH (PIR-B 12, 1C 4.88 / VN Ku) known in this product information
  • the spotlights described are spotlight modules that can be assembled into spotlights of any size in any position.
  • the individual radiator modules are attached with their rear wall to very stable support frames.
  • the rear wall of the housing or a rear wall plate is simultaneously designed as a reflector. So that the radiator modules can be joined together without a gap, the side walls of the housing, if present, are arranged perpendicular to the rear wall; Adjacent, adjacent side walls thus lie flat against one another. Since these radiator modules do not have a separate reflector, the screw elements on the rear wall are easily accessible in order to attach or detach the radiator modules to the carrier unit. Even in a large radiator unit, individual modules can be removed, for example if the reflector is damaged.
  • the radiator modules shown in the second-mentioned product information have a very complex, but extremely stable housing, which is composed of a large number of parts. These radiator modules are assembled into small units if necessary, e.g. B. in pairs, which can be articulated to each other to be able to irradiate curved surface parts, such as the fender of a motor vehicle, for drying a paint at the same distance.
  • radiator modules are used with a box-shaped housing, a rear wall and side walls running perpendicular to the rear wall, in which two opposite edges of the side walls are chamfered inward approximately parallel to the surface of the side wall with a remaining space, so that a guide groove on these two side edges is formed.
  • a trough-shaped reflector is inserted into this guide groove from an open side wall of the housing, the reflector part having edge parts that are supported from the inside of the housing in these grooves.
  • the individual emitter tubes are located in front of the trough-shaped reflector part.
  • a defective radiator module has to be removed from such a unit, the unit must be disassembled starting from one side up to the defective radiator module, since the guidance of the reflector parts in the grooves, as described above, gives access to the connecting elements located behind the reflector part is not possible because such reflectors can only be removed from the side of the emitter module.
  • the present invention is based on the object of specifying a radiator module, in particular an infrared radiator module, which can be assembled and disassembled in a simple manner with regard to the housing and the reflector part, in which the reflector part is kept centered in the housing and which is so in terms of the connecting elements, with which it is assembled into a radiator module unit, it is constructed that individual radiator modules can be removed from an entire radiator unit and reinserted without great assembly effort.
  • a radiator module in particular an infrared radiator module
  • the two edge parts of the reflector part can be bent to the actual reflector in such a way that the bending line lies directly against the free edge of the side wall edge parts.
  • the edge parts do not protrude from the outside of the housing, so that adjacent radiator modules can be joined together flatly with the side walls to form a large radiator unit.
  • intermediate parts can be used between radiator modules, so that these edge parts must not protrude beyond the outside of the intermediate parts.
  • the reflector part can be removed from the open housing side in this embodiment. Then the connecting elements, which are designed as bores in the side walls, are accessible, it being possible, for example, to use screwed connecting elements through these bores.
  • radiator module units By connecting such radiator modules via the holes in the side walls, with correspondingly stable or reinforced side walls, self-supporting radiator module units can be assembled without the need for heavy and massive support frames. Since the unit has a closed box profile when assembled, it is not only rigid, but also has high torsional rigidity. In this way, even extensive structures can be designed to be self-supporting.
  • fastening elements are provided with which the reflector part is screwed to the rear wall. These fasteners can be released from the outside of the reflector.
  • the side wall edge parts preferably run at right angles to the side walls, the opening width of the open housing side being somewhat reduced by these bent edge parts. Depending on the size of the radiator module, the width of these side wall edge parts is approximately 10 mm to 20 mm. In this embodiment of the side wall edge parts, a good contact of the reflector edge parts is made possible.
  • the reflector edge parts are seen in cross-section in the direction of the side wall surface assigned to the respective edge parts with a rounded profile, which for example can be bent directly from the reflector sheet, the opening of such a profiled edge in the direction of the rear wall of the Housing points.
  • the reflector edge parts adjoin the inwardly angled side wall edge parts in each case a surface section which runs parallel to the associated side wall and extends into the rounded, open profile of the corresponding reflector edge part. In this embodiment, a particularly good centering of the reflector part on the housing is achieved.
  • the recessed area of the side wall of the housing delimited by the surface section is designed to have a width which corresponds at least to the thickness of the part of the reflector edge part adjoining this area. Since the reflector sheets used can be very thin, a width of a few millimeters is sufficient for the recessed area.
  • the side wall edge parts can also have a rounded, curved profile, such a profile, corresponding to such a profile on the reflector edge parts, also having the opening in the direction of the rear wall. If such rounded profiles of the side wall edge parts are used in connection with rounded profiles on the reflector edge parts, the profiles should be matched in their curvature so that they lie flat on one another with a view to a good hold and exact centering. The rear of the housing does not have to be accessible to remove or replace the reflector.
  • the space between the rear wall of the housing and the reflector base can be equipped with suitable air baffles and ventilated for cooling.
  • connecting elements are attached to the rear wall of the housing, into which the locking parts or screws engage and which fix the reflector base at a distance from the rear wall of the housing.
  • Reinforcement profiles can be used in this space, for example, in order to reinforce a very thin housing, in particular in the area of the connecting elements, on the side walls.
  • L-profiles are preferably used for this purpose, or node elements which are formed from three sheets which are at right angles to one another and which rest in the corner regions of the housing and the base surface.
  • a plurality of the radiator module parts described above are preferably combined to form a radiator unit, adjacent radiator modules being connected to one another via the connecting elements in the side walls. So that a radiator module unit can be constructed, it is necessary for the individual radiator modules to have a geometry in their housing base surface which enables the individual radiators to be assembled seamlessly into a radiator field.
  • Such basic housing shapes are, for example, rectangular, square or hexagonal in the form of a honeycomb.
  • the radiator module 1 has a box-shaped housing 2 with four flat side walls 3 which run perpendicular to the bottom surface 4 of the housing 2.
  • the radiator module 1 has a square shape in plan view, ie in its base area.
  • the housing is open opposite the bottom surface 4, a trough-shaped reflector part 5 being inserted into this open side.
  • This reflector part has a reflector rear wall 6 which runs at a distance from the bottom surface 4 of the housing 2, forming an intermediate space 7.
  • These reflector edge parts 10 run parallel to the reflector rear wall 6 and to the bottom surface 4 and at right angles to the associated side walls 3 of the box-shaped housing 2.
  • the reflector part 5 is folded from a one-piece sheet metal.
  • In the space between the trough-shaped reflector part 5 and the upper edges of the Housing 2 has a plurality of radiation tubes 11 arranged with their axes 12 parallel to the reflector rear wall 6.
  • the direction of radiation of the radiator module is indicated in FIG. 2 by arrow 13.
  • the reflector edge parts 10 rest on side wall edge parts 14 on opposite side walls 3 of the housing 2.
  • the edge parts as in the embodiment of the radiator module 1 in Figures 1 and 2, extend at right angles to the side walls 3 to the inside of the housing 2, so that the clear opening width of the housing 2 in the interior between the opposite side walls 3 is reduced.
  • the trough-shaped reflector part 5 lies with its reflector edge parts 10 flat on the side wall edge parts 14 on the outside thereof, ie on the side facing away from the bottom surface 4.
  • the reflector part 5 is fastened to the bottom surface 4 of the housing 2 with fastening elements 15.
  • These fastening elements 15 consist of spacers 16 which are fastened on the one hand to the bottom surface 4 and against which the underside of the reflector rear wall 6 abuts.
  • the reflector rear wall 6 is screwed from the outside with screws 17, as shown in detail in FIG. 3. These screws 17 engage in an internal thread of the spacer parts 16 and fix the reflector part 5 in the housing, in the direction or against the direction of the radiation arrow 13. Threaded rods can also be used as spacers 16.
  • the reflector part 5 is centered in the housing 2 via the superimposed reflector edge parts 10 and side wall edge parts 14. After loosening the screws 17 on the connecting elements 16, the reflector part 5 can be removed from the housing 2 in the direction of arrow 13.
  • the reflector part 5 of a radiator module 1 is usually held with four such fastening elements 15.
  • FIGS. 1 to 3 also show, four bores 18 leading through the side walls 3 are provided in the side walls 3 of the housing 2, via which, as shown in FIG. 3, adjacent radiator modules 1 also have Connecting elements 19 are screwed, the side walls lying flat on one another.
  • the connecting elements 19 each consist of a connecting screw 20 which engages in a connecting nut 21.
  • the side walls 3 of adjacent radiator modules screwed together lie flat on one another.
  • the housing 2 can be backed with L-profiles 22 or node elements in the area in which the bores 18 are located.
  • the node elements reinforce the housing in the area of mechanical connections or the connection between adjacent radiator modules and increase the torsional rigidity when disassembled.
  • L-profiles 22 one leg rests on the corresponding side wall 3, while the other leg rests on the bottom surface 4, in which further connecting elements 24 can be located.
  • these L-shaped profiles 22 can each abut in the corner area of adjoining side walls 3 and the holes 18 present there, as is shown schematically in FIG. 7 in the broken area of four adjoining radiator modules 1. The holes 18 lead through these profiles. If gusset plates are used, corresponding to FIG. 8, the surfaces of these plates lie both on the two side walls 3 and on the rear wall 4 in the corner region of the housing 2.
  • FIG. 4 shows an embodiment which has already been described with reference to FIGS. 1 and 2.
  • Figure 5 shows an embodiment, at which, compared to FIG. 4, adjoins a recessed surface section 23 on the side wall edge parts 14, the surface of which extends parallel to the surface of the assigned side wall 3. The length of this surface section 23 is approximately 20 mm.
  • the edge part 10 of the reflector of the reflector part 5 assigned to this side wall edge part 14 or to the surface section 23 has a rounded profile in cross section with the opening pointing towards the bottom surface 4 of the housing 2, the bottom of the opening or the bottom of the channel thus formed countering the outer free end face of the surface section 23 abuts.
  • the reflector edge part 10 lies flat against the outside of the surface section 23.
  • the offset of the surface section 23 to the inside of the housing 2 is chosen so that the reflector edge part 10 does not protrude beyond the outside of the associated side wall 3.
  • both the side wall edge part 14, which also extends to the inside of the housing 2, and the reflector edge part 10 are curved as profiles with a rounded cross-section with mutually adapted radii of curvature, so that the two edge parts 10, 14 lie flat on top of one another and thus ensure exact centering of the reflector part 5 in the box-shaped housing 2.
  • the configuration of the edge parts 10, 14 according to FIG. 3 corresponds to the schematic illustration according to FIG. 6.
  • the radiator module unit according to FIG. 7 can be composed of individual radiator modules 1, as described with reference to FIGS. 1 to 6, the side walls of adjacent radiator modules 1 being screwed to one another via connecting elements 19.
  • the radiator module unit In order to remove an individual radiator module 1 from the radiator module unit, only the reflector part 5 on the fastening elements 15 is detached and taken out in the radiation direction to the front, the radiation tubes 11 of course not having to be removed beforehand. Then you can Connecting screws 20 are released from engagement with the connecting nuts 21 of the connecting elements 19. Instead of the connecting nut 21, threads can also be cut into the L-profiles 22 or node elements, as shown in FIG. 8, which then replace the connecting nut 21. If such connecting nuts 21 are each arranged on the inside of the side walls, for example welded or soldered, the connecting screw 20 can be screwed through the adjacent side walls 3 without the opposite connecting nut 21 having to be held.
  • FIG. 8 shows a node element which, as already mentioned above, can be used for reinforcement in the corner region of the housing 1.
  • the bores can be seen which are in register with the bores 18 of the side walls 3 of the housing 1 (two each); the lower part of the node element has an additional hole for a possible fastening hole in the bottom of the housing 1.
