Definitions

  • the invention relates to a radiator, in particular a radiator, comprising at least one radiator block with heating tubes oriented perpendicularly to and fixed to a collecting tube, which have different diameters, in particular in their cross-sectional plane in the longitudinal and transverse directions.
  • Such a radiator is known from DE-PS 26 07 95.
  • the wrought-iron header pipes have cut-outs from the full wall, adapted to the shape of the heating pipes, on the edges of which the wrought-iron heating pipes pierced at these points are welded.
  • the heating tubes, each with the same oval cross-section, lie in the cutouts.
  • Such a radiator provides a fixed thermal output.
  • the radiator consists of individual links of the same size, which are strung together.
  • the heating pipes can be arranged on either side or on one side of a collecting pipe section or can be connected in a row by collecting pipe sections.
  • the tubes are each formed by two thin metallic walls, which are inserted concentrically into one another and only have a space of a few mm between them for the heating fluid to flow through. This should in particular greatly reduce the space requirement and increase the heating area.
  • one or the other embodiment of the radiator is then to be used.
  • radiators are not particularly pressure-stable, particularly when using heating tubes with a drop-shaped, double-drop, oval or elliptical cross section, so that deformation cannot be ruled out.
  • the invention is therefore based on the object to provide a radiator of the type mentioned, which enables a fine gradation of the heat output with high pressure stability of the heating pipes.
  • the stated object is achieved by a radiator, in particular a radiator, of the type mentioned at the outset, which is characterized by protection against deformation against pressure loading inside the heating pipes.
  • a radiator in particular a radiator, of the type mentioned at the outset, which is characterized by protection against deformation against pressure loading inside the heating pipes.
  • heating pipes with a cross section in the form of a flat oval or a flat rectangle, in which the diameter in the longitudinal direction, for example, can also be used can also be up to four to five times the diameter in the transverse direction.
  • Such heating pipes are also sufficiently pressure-stable due to the inventive design and secured against deformation caused by pressure.
  • radiators with a variety of power levels can then be produced in fine gradation of the heat output.
  • the radiator consists in particular of sheet steel, which is shaped in the desired manner.
  • the deformation safeguards are separate inserts which can be inserted into the heating pipes.
  • the insert parts preferably have a zigzag shape with rounded tips.
  • these deformation safeguards can be fixed on the heating tube.
  • Such pressure stabilization is particularly advantageous for flat oval tubes, the depth of which is four to five times their width.
  • the protection against deformation is determined in the interior of the heating pipe in the most pressure-sensitive area, the middle area. The insertion of this fuse or the fixing of the pressure holder can be carried out by soldering under protective gas while simultaneously soldering the head pieces of the heating tube.
  • a further, extremely preferred embodiment of the radiator provides that the deformation safeguards are designed as webs inserted into the interior of the heating pipes and non-releasably connected to them, the deformation safeguard in particular being designed as an H or double-T web.
  • the deformation protection at the areas connected to the inner wall of the heating pipes to the constant Contour of the wall of the heating pipes adapted, in particular is rounded.
  • the anti-deformation devices connect the pipe walls in the area of the smaller extension of the oval or elliptical cross section of the pipes. If only a single anti-deformation device is provided across the cross-section of the tubes, this will in principle be arranged in the center, ie in the small diameter of the oval or ellipse. However, two or more deformation locks can also be used next to one another, which are then preferably arranged symmetrically.
  • the heating tubes are each formed by two heating tube halves which are connected to one another at their mutually facing ends, the heating tube halves each having a leg projecting in the direction of the interior of the heating tube.
  • the legs serve as protection against deformation against pressure loads.
  • the two heating tube halves which are preferably formed in one piece in order to keep the number of weld seams as small as possible, are sealingly fixed to each other at their mutually facing ends on each side via a longitudinal weld seam.
  • the limbs of the heating tube halves projecting into the interior of the heating tube lie against one another at least in the region of the longitudinal central axis L of the heating tube.
  • the deformation is secured under pressure in that the legs of the heating tube halves abut one another parallel to one another, the heating tube halves preferably being closed by the legs at their mutually facing ends.
  • the deformation safeguards are located in the central region, as in the previous exemplary embodiment, that is to say the weak point of the heating pipe to be formed.
  • both exemplary embodiments are distinguished by the fact that two identical heating tube halves are used to manufacture such a heating tube with deformation protection, which not only form the heating tube when rotated through 180 °, but at the same time also provide reliable deformation protection in the interior of the heating tube.
  • heating pipes are arranged on the front and rear of the collecting pipe with different depths, the same heating pipes being arranged on one side of the collecting pipe. This results in very fine gradations in connection with the use of pipes of different cross-sectional dimensions the thermal output and thus a more precise design according to the respective heat requirements of the rooms.
  • the heating pipes on the front and rear of the collecting pipe have the same width, the visual impression from the front remains the same despite the different depths of the heating pipes.
  • This also makes it possible to connect radiator blocks of different depths to form a radiator.
  • the preferably releasably coupled radiator blocks in a preferred embodiment have different lengths in order to create radiators of any length. Because the radiator blocks are easy to nipple, the connections between them are easy to disconnect.
  • the heating tube 2 of a radiator 1 shown in FIG. 1, which is elliptical or oval in cross section, has two heating tube halves 3, 4 of identical dimensions.
  • the two half-elliptical and identical heating tube halves 3, 4 are fixed to one another at their mutually facing ends 5, 6 by welding.
  • the weld seam runs in the longitudinal direction of the heating tube 2.
  • the diameter a in the longitudinal direction is approximately 2.5 times the diameter b in the transverse direction.
  • the diameter ratio can, however, also be 3.5 or 4.5 times, the diameter b, that is to say the width of the heating tube 2, forming a constant size, while the diameter a changes in the longitudinal direction, that is to say the depth .
  • Both heating tube halves 3, 4, each formed in one piece each have a bent leg 7, 8 which projects into the interior of the heating tube. In the exemplary embodiment shown, these legs 7, 8 run parallel to one another and lie against one another over their entire sections running parallel to one another to form a deformation lock 9. At their mutually facing ends 5, 6, the heating tube halves 3, 4 are each closed by the associated legs 7, 8.
  • the heating tube 12 shown in FIG. 2 is in turn formed from two identical heating tube halves 13, 14, the heating tube 12 having the same depths: width ratios as the exemplary embodiment in FIG. 1.
  • the heating tube halves 13, 14 are in turn fixed tightly to one another via a weld seam.
  • the heating tube halves 13, 14 each have legs 17, 18 projecting into the interior of the heating tube. These legs 17, 18 projecting into the interior of the heating tube lie against one another at least in the region of the longitudinal central axis L of the heating tube 12. For this purpose, the legs 17, 18 are bent in a hook shape at their free ends 20, 21.
  • the free ends 20, 21 are each bent in a parallel orientation to one another, the free ends 20, 21 of the legs 17, 18 each lying in the receptacle 10, 11 formed by the hook-shaped bend . In this way, a deformation protection 19 is also created in the central region of the heating tube 12.
  • the heating tube 22 is integrally formed.
  • the heating tube 22 has a ratio between depth a to width b of 4.5.
  • a separate insert part 29 is inserted inside the heating tube 22 as a protection against deformation.
  • the insert 29, which is less thick than the tube wall, has a zigzag shape with rounded tips 23, 24. In the area of the rounded tips 23, 24, the insert part 29 is fixed to the heating tube 22 by spot welding.
  • FIGS. 1 and 2 show a cross section through a heating tube 2, which is elliptical in section and has an outer contour similar to that of FIGS. 1 and 2.
  • the heating tube 2 can be produced from a seamless round tube, for example by deformation processes of such a round tube into an ellipse, which are known per se - or oval tube.
  • the heating tube 2 has a deformation lock 41 in the form of a web 42.
  • the web 42 is designed as a double T or H web. It has a connecting part 43, on the two end faces of which widenings 44, 46 are formed.
  • the curvature of the outer contour 47 of the widenings 44, 46 is matched precisely to the inner curvature of the heating tube 2 in the contact area of the deformation protection 41 on the inner wall of the heating tube 2. This ensures that even after connecting the wall of the radiator 2 to the anti-deformation device 41, the wall in the connection area maintains its constant curvature and no flattening appears on the outside.
  • the connection is made in a manner known per se by welding or soldering.
  • FIG. 5 shows a heating element 1 which has a horizontally aligned collecting tube 31, on the front and rear sides of which heating tubes 32, 33 are arranged perpendicular to this.
  • the heating tubes 32, 33 each have the same width but different depths.
  • the heating tubes 2, 12, 22 shown in FIGS. 1-3 can be used as the heating tubes 32, 33, for example.
  • Heating pipes 32 and 33 of the same depth are arranged on one side of the collecting pipe 31.
  • the heating pipes 32, 33 are on hers
  • the upper and lower sides are each provided with head pieces 34, which are fixed, for example, by soldering to the heating pipes 32, 33.
  • the heating pipes 32, 33 are fixed to the collecting pipe 31 by cross welding (pressure welding) in the area 35.
  • the elliptical heating tubes 32, 33 shown can be used in particular, since they are stiffer in this area and allow a desired deformation in the cross-welding area 35, which contributes to the mechanical strength of the welding spot.
  • radiator blocks can be connected to form a radiator via connection and nipple connections, not shown here.
  • the invention is not limited to the exemplary embodiments described and illustrated, but can be varied in a large number of designs and types which are within the basic concept of the invention.
