Definitions

  • the invention relates to a tube bundle for boiler heat exchangers, essentially consisting of parallel to each other arranged metallic pipes.
  • the invention further relates to a process for the production of tube bundles for Boiler heat exchanger, the tubes at least one End widened, the tubes are bundled afterwards, and welded each tube in the tube bundle to the neighboring tube becomes.
  • Such a tube bundle and a method for its production is for example from patent application 195 01 276.3-16 known.
  • the tube bundle described there essentially consists from pipes that are polygonal at their ends and in have substantial conical flares, each tube in the tube bundle at the expansion edges of the expansion with the adjacent edges of the adjacent pipes are welded is.
  • Such a tube bundle can be made with the least possible work equipment and produce very little material, since no pipe disks are required. Furthermore
  • the well-known tube bundle enables the production of heat exchangers in a very compact design. Such heat exchangers stand out compared to conventionally manufactured heat exchangers through a higher heating surface in less space and through better efficiency.
  • the expansion of the known tube bundle takes place with a deformation process, for example a cold forming process. This can be done by a hydraulic pressure medium, but there are also other expansion methods conceivable.
  • the expansion is equilateral and is hexagonal, quadrangular or triangular.
  • hexagonal, quadrangular or triangular equilateral widened tubes are bundled so that the polygonal widening, the tube bundle end faces without gaps parquet. Especially with an equilateral hexagonal expansion this then results on the tube bundle end faces a particularly favorable honeycomb structure.
  • tubes are expanded on the same side only with pipes with similarly designed pipe widenings can be bundled in such a way that the polygonal widenings of the tube bundle end faces Park without gaps.
  • the invention is therefore based on the object of a tube bundle for boiler heat exchangers of the type mentioned at Maintaining the benefits described above essential to simplify.
  • the invention is also based on the object of a new one To provide manufacturing process, which is a more economical Production of the tube bundle enables, a space-saving connection of the pipes to each other is sought.
  • the object is achieved in that the Pipes in one piece at least at one of their ends have this trained flange-like collar, which in essentially in a roughly perpendicular to the longitudinal axis of the Pipe trending plane are arranged and that the pipes in Area of the edges of the collar are welded together.
  • a tube bundle with such tubes is much simpler and Can be produced more cost-effectively, the pipes are one below the other relatively easy to connect.
  • the flange-like collars can be polygonal Have contour and welded together at their edges be. They are preferably of the flange type Collar formed polygons equilateral, these can be pentagonal, be hexagonal, quadrangular or triangular.
  • the tubes are preferably bundled in such a way that the edges lie against each other and parquet without gaps.
  • the tubes in this way are bundled that the polygonal collars the tube bundle end faces patchy parquet and that in the gaps corresponding sheets or tubes with corresponding widenings and / or collar are welded.
  • the collar overlaps are welded together, d. that is, a closed Pipe bundle face by overlapping one another Collar of adjacent tubes is formed.
  • the object underlying the invention will continue solved by a method of the type mentioned, the is characterized in that the expansion by round Flanging or flanging of the pipe end takes place so that a All-round, flange-like collar is created, which is essentially in a right angle to the longitudinal axis of the tube extending plane.
  • the expansion is independent of the respective series and can also be done with a simple, standard mandrel, so that no special tool for making the Pipe widening is required.
  • flange-like collars by crimping the preferably made of steel or stainless steel pipes Their ends naturally have collars that have a round contour exhibit.
  • This flange-like collar can be welded in this way be that their tube bundle end faces parquet patchy.
  • the flange-like collar on their Edges are welded together.
  • the Gaps are welded to a closed sheet Get face.
  • the essentially circular collars one above the other and / or one below the other laid, d. H. are welded to one another in an overlapping manner. In this way, one can be almost complete closed tube bundle face are generated.
  • the pipes are made using filler metals welded together, so due to dimensioning and Manufacturing tolerances for joints with the filler metal filled up and thus securely closed.
  • edges of the collar can be closed after widening Polygons are cut and cut by cutting formed edges are welded together. Lying there the corners of the polygons preferably on the peripheral edge of the round collar to prevent possible cutting losses.
  • the flange-like collar of the adjacent tube bundle in this way form a closed end face, is an entry when using the tube bundle in heat exchangers guaranteed of the exchange medium up to the collar, with which an adequate heat dissipation is realized. This is especially necessary if the tube bundle, for example the temperatures are flowed through by hot smoke gases can have up to 1,000 ° C, and sufficient Cooling of the welds is necessary.
  • the cut of the collar triangular, hexagonal, quadrangular, pentagonal as required or more than hexagonal In a first manufacturing step, the tubes can initially be flanged and then in a second step can be cut to the required shape.
  • the flaring is independent of the one to be manufactured Series, which reduces the storage effort for the pipes becomes.
  • the tube bundles according to the invention exist 1 from tubes 2, which are flared at least at one end are that a circumferential, flange-like collar 3 arises, which is essentially at right angles to Longitudinal axis 4 of the tube 2 extending plane extends.
  • the Pipes 2, which are made of stainless steel in this embodiment, are bundled and on the square after cutting formed edges 8 of the collar 3 with weld seams 9 connected with each other.
  • the process enables an extremely compact construction of tube bundles, in particular of heat exchangers.
  • the manufacture of the flange-like Collars can be done with simple tools.
  • the flange-like Collars can be cut polygonally as required be so that the flaring of the pipes independently of the respective series to be produced. To this The storage effort for interim storage is expanded by way Pipes for different series of heat exchangers avoided.
