Definitions

  • the invention relates to a special profile for lightweight fan / filter modules to create local clean rooms with defined environmental conditions by generating a decontaminated, low-turbulence displacement flow and for use in clean room ceilings using prefabricated suspended solids filter inserts according to the preamble of patent claim 1.
  • Clean rooms are known in the semiconductor industry, but also clean room techniques are required in other industrial manufacturing and research processes. In many industries, production must be carried out under clean environmental conditions. For example, here are the food industry, environmental technology, pharmacy, precision mechanics, optics and so on.
  • Creating active mini-environments creates a low-turbulence displacement flow. As a rule, there is an active flow through which pure air from the clean room itself can be used. For this filter / fan modules are used.
  • the generic DE 197 09 834 A1 relates to a modular generating unit for purified gases, where there is a special extruded profile is used, which is designed as a hollow profile.
  • the groove should extend to the inside.
  • the object of the invention is achieved by a special profile for lightweight fan / filter modules according to the feature combination according to claim 1, wherein the dependent claims represent at least expedient refinements and developments.
  • the profile forming the side walls of the module has a flat, essentially flat base surface.
  • a first and a second web are designed as outer webs located in the edge region of the longitudinal edges of the base.
  • An inner web closely adjacent the first outer web forms a further component of the profile, with the webs running substantially parallel.
  • the opposite inner sides of the first outer web and the inner web have fastening surfaces or a special fastening structure, specifically for receiving a prefabricated filter insert.
  • outer sides of the outer webs comprise a recess for receiving a seal, in particular a sealing profile, wherein in the second outer web, extending substantially parallel to the longitudinal axis of the flat, flat base, a narrow groove for driving screws or the like fastening means is provided.
  • the recess for receiving the seal in the second outer land is, starting from the surface plane behind the groove for the drive screws, i. arranged in the direction of the end of the bridge.
  • the recesses for the seals may have a rectangular or similar cross section and preferably run parallel to one another and with their broad side substantially perpendicular to the base surface plane.
  • the second outer bridge protrudes in height from the first outer bridge.
  • An outer edge of the second outer web is designed as a stop for a module cover plate, wherein this module cover plate can be fastened by means of the drive screws on profile.
  • the narrow groove may have in one embodiment of the invention in its Nutö Stamms Symposium Series a conical cross-section or a one- or two-sided chamfer, so that the fastening means can be safely guided and introduced even with unavoidable tolerances without undue effort.
  • the mounting structure for receiving the prefabricated filter insert can be formed as a profile groove, in particular T-profile groove.
  • the module cover plate comprises air inlet openings, wherein the fans of the module are fastened to the cover plate.
  • the distance between the first outer web and the inner web is approximately in the range between one third to one quarter of the total profile width.
  • the total profile width in turn is in the range between 150mm to 250mm, preferably at substantially 200mm, the profile width basically determines the height of the module.
  • the prefabricated filter insert forms part of the module outer housing, wherein further housing parts represent the profile itself and the cover plate.
  • fans / filter modules of different width and length dimensions but also of different shape, eg as cuboid, rectangle or polygon, depending on be realized the available pre-assembled suspended matter filter cartridge.
  • the figure shows a cross section of the special profile as well as details of the webs extending from the profiled surface and the grooves or recesses provided there.
  • the special profile according to the figure initially comprises a flat, flat base surface 1, wherein a plurality of webs extend from the base surface 1 in each case in the same direction.
  • a first web 2 and a second web 3 are formed as located in the edge region of the longitudinal edges of the base 1 outer webs.
  • the webs 2 to 4 are substantially parallel and extend substantially perpendicular to the surface of the base 1.
  • the opposite inner sides of the first outer web 2 and the inner web 4 have attachment surfaces 5 or a mounting structure for receiving the prefabricated filter insert 6 shown symbolically.
  • the attachment surfaces 5 or the attachment structure may be formed as a T-shaped groove, as shown in the detailed illustrations.
  • outer sides of the outer webs 2 and 3, but at least the outer side of the web 3 has a recess 7 for receiving a seal 8 or a corresponding sealant.
  • the indicated module cover plate 10 can be connected to the special profile.
  • the recess 7 for receiving the seal in the second outer web 3 is arranged starting from the base plane behind the narrow groove 9 in the direction of the free end of the outer web 3. With inserted seal 8 and mounting the cover plate 10 by means of propellers in the narrow groove 9 is ensured by this arrangement that may accumulate chips do not get into the interior of the fan / filter module and possibly contaminate it.
  • the recesses 7 for the seals have a substantially rectangular cross-section and are oriented parallel to each other.
  • the second outer web 3 projects beyond the height of the first outer web 2 and has an outer edge 11 as a stop for the module cover plate 10th
  • the narrow groove 9 has at its Nutö réelles Society a conical cross section 12 and a corresponding chamfer, so that the fastening means, in particular the propeller screws can be easily introduced on the thus resulting guide section.
