  • the oval tubes, which are divided into two elongate chambers by a partition, in particular for convectors, are in no way disclosed in the document with regard to their connection to heat medium areas.
  • the known radiators are designed such that to be dried or towels to be preheated are placed over an essentially horizontal holding tube must be accessible, which is only accessible from above, but not from one side.
  • the towels must therefore be placed over the heating pipe from the front. Are the Heating tube spacing is small, the towels must be properly threaded.
  • the object of the invention is to further develop a radiator of the generic type in such a way that the radiator is more flexible with regard to the possible variations in the arrangement of supply, return and heating pipes, is inexpensive and economical to manufacture and favors automation of the production process.
  • the radiator according to the invention is intended to enable a to be able to slide the preheated towel on the side of a heating pipe.
  • each heating tube is connected in the region of one of its ends to the flow and return lines and is divided into two interconnecting chambers, one of which is connected to the flow and return line is.
  • the heating tube can be used with regard to Openings for the flow or return can be designed extremely variable. It for example, it is possible to combine the supply and return lines in one Arrange central body and the heating pipes protruding from one side of the central body to attach to this.
  • the chambers in Heating tube longitudinal direction formed.
  • the Chambers formed by dividing plates running in the longitudinal direction of the tube. With It is particularly advantageous that the divider at least in Partial areas is rotated helically.
  • the divider in the area of the openings for the flow or the return is turned helically. Is in this area between the in both openings, the divider is rotated by at least half a turn, the rest of the area can remain straight.
  • a partition is arranged which separates the two chambers from each other.
  • the Water thus enters the heating pipe through the flow opening and flows through both Chambers in the longitudinal direction of the tube and passes beyond the partition through the practical next to the opening mentioned first return opening again.
  • the two chambers are through formed a double tube arrangement.
  • a pipe with a smaller diameter is in a tube with a larger diameter is used.
  • the partition can between the flow and the return connection by expanding the pipe Inner tube are formed.
  • the other end of the inner tube can be used to form Spacers are bent up. This is a simple way Two chamber tube formed.
  • the inner tube is formed so that it is only on one part of the inner wall of the heating pipe is sealed, while the other Space between the inner tube outer wall and the inner tube of the heating tube remains.
  • the inner tube can then be positioned closed on one side so that that the closed wall between the opening for forward and return is arranged.
  • the respective opening, which must be arranged in the area of both pipes is then, for example, by punching both in the heating tube and in Inner tube formed at the same time.
  • connection between the two chambers is made according to a proposal of the invention by arranging an opening in the partition in the area of the pipe end edges. This opening is advantageously through a cutout in the separating plate educated.
  • end caps can be attached to the pipe end edges, that connect the two chambers.
  • the heating tube is advantageously flattened, plate-shaped Tubular body formed.
  • the flow or return lines arranged vertically.
  • the lead and Return lines as a pipe with two longitudinally running chambers be trained.
  • the lead or Return lines can be arranged in a central body.
  • the heating pipes are according to a proposal of the invention to the flow and Return lines arranged at an angle, preferably horizontally.
  • the angle between a heating pipe and the flow and return lines is 15 ° to 90 °.
  • the radiator according to the invention is with regard to its possible variations extremely flexible and also economical and inexpensive to manufacture. Finally, it favors the automation of the manufacturing process. For example, it is possible to use two parallel vertical lines as and form return lines and horizontal thereon, in one direction to arrange protruding heating pipes fastened on one side. Any can spatial designs are made, such as helical arranged heating pipes and the like.
  • FIG. 2 and the side view in FIG. 3 are connecting pipes 5 between the lines 2, 3 and the heating pipes 4 arranged, which gives the radiator a corresponding depth.
  • the connecting pipes 5 can also be omitted, so that the in FIG. 4th obvious side view results. Otherwise, this embodiment corresponds to shown in Figure 1.
  • Another alternative embodiment is in side view shown in Figure 5, where on both sides of the flow and return lines 2, 3 heating pipes 4 are arranged.
  • the heating tubes can be changed at the end in any change be arranged so that there is a high degree of variation.
  • the flow and Return lines realized in a central body 6. It can be one with one Acting a partitioned pipe.
  • the pipes are connected to port 8 Fittings, pipes and the like can be connected.
  • the heating tube 7 is a single tube arranged in a snake shape, which is extremely variable and economical to manufacture in terms of design.
  • connection between the heating pipes and the flow or return lines expediently takes place by means of cross-hole welding. This simple Process is suitable for automation of radiator production and is extremely economical.

  • Recesses 13 can also connect both chambers on the tube End caps may be arranged.
  • the heating pipes are to be attached to the ends of the heating pipes under end caps sealing caps to understand, however, since those in the tubes arranged partitions do not protrude into the caps, automatically one Connection between those formed by the partitions in the heating pipes Create chambers.
  • the divider is as helically turned sheet.
  • the partition between the return or Flow openings 10, 11 thus result automatically. It’s enough if the partition plate only in the area of the return or flow openings 10, 11 is helically rotated by at least half a turn. The remaining Areas of the partition plate can then be formed without rotation, since it only depends on the fact that a separation between the return or flow opening 10, 11 is formed.
  • Recesses 13 may be formed on the pipe ends or end caps on the Pipe can be applied. The function of the end cap is only the top and the To connect the underside of a divider. If this is sufficient the recesses can also be configured as simple bores.
