Definitions

  • the invention relates to a tubular heater and a method for its production.
  • Conventional tubular heaters for example, in the publications CH - PS 449 891 .
  • DE 198 00 230 C2 and DE 93 14 040 U1 disclosed.
  • DE - OS 15 79 967 a radiator element and a heater made from such elements will be described.
  • Tubular heaters often consist of several adjacently arranged and connected to the hubs similar radiator members.
  • the radiator members usually consist of welded together sheet metal shells, being welded to produce larger designs between pipe connection piece formed from sheet metal shells end pieces of pipes. Due to the length of the tubes, the overall height of the radiator elements can be made variable and adapted to the respective requirements.
  • the flow through the plurality of layers of radiator members is usually in the same direction, for example, in vertical heating tubes either in a flow direction from bottom to top or top to bottom, depending on the arrangement of flow and return port.
  • a radiator generates greater comfort and the heat losses to the outer wall, on which radiators are usually mounted, are lower when the directed into the room side of the radiator is preferably flowed through.
  • a tubular radiator is already known, which emits a higher radiation power at its front than at its inner or rear pipe layers.
  • the device required for this limits the connection types of the radiator and means an additional design effort with respect to the installation.
  • fittings must be kept in the appropriate dimensions.
  • a tubular heater of another type is from the DE 20 2007 005 330 U1 known.
  • the tubular radiator has Collecting tubes, which include a device that allows a targeted flow through the room facing the tube wall.
  • the tubular radiator differs in appearance from the traditional shape of the tube radiator and is therefore difficult to accept by customers.
  • the object of the invention is to provide a tube radiator of new type with at least two layers of heating tubes, which emits at its front side a higher radiant power than at its rear and / or inner layers of heating tubes, while maintaining the traditional look of a conventional Röhrenradiators , Another object of the invention is to provide a method for producing such a tubular heater, with which the above object is technically feasible at economic production costs.
  • the header segments of the tubular heater be produced by means of the method known as "hydroforming” or “hydroforming (IHU)".
  • the hydroforming process is well known and described in the pertinent literature.
  • a pipe section for example made of steel or copper, is inserted into a multi-part hydroforming die without a fixed inner die with sealing dies or forming tappets actuated by axial cylinders.
  • the pipe section After closing the ends of the pipe section by the sealing ram, the pipe section is acted upon by means of a suitable pressure medium with high internal pressure and with simultaneous application of axial pressure (by the sealing ram) formed on the pipe wall.
  • the axial pressure and the internal pressure cause the pipe section to conform to the final shape of the Hollow body having inner contour or wall of the contour space of the forming tool applies.
  • the material In the hydroforming process, the material is placed in the plastic state, which is maintained during the entire process, taking into account material hardening and possible tool forces. From the DE 199 54 456 A1 It is known to produce water-bearing fittings from the sanitary and heating installation, namely thin-walled soldering in the form of tees by this method.
  • the present invention accordingly comprises a tube radiator optically consisting of a plurality of juxtaposed conventional radiator elements and identifies at least two successively arranged rows of tubes from vertical heating tubes, wherein the vertical heating tubes are fluidly connected at their opposite tube ends respectively with horizontal manifold segments and the manifold segments have a Schiederrohroptik and with at least partially fluid-conducting connecting parts are interconnected.
  • the limb-pipe structure of the manifold segments is formed by a cross section that varies over the length of the collector pipe segments.
  • the manifold segments are provided with pipe connection pieces, which are connectable to the vertical heating pipes.
  • the collecting pipe segments have pipe connecting pieces which are at least partially connected fluid-conductively to the respective collecting pipe segment lying behind them.
  • the lateral pipe ends of the manifold segments are closed by covers and / or there are provided with threaded sleeves for connection to a heating circuit cover.
  • the heating tubes of the room facing the front side of the radiator are preferably flowed through by connecting configuration of flow and return of the heating fluid and corresponding fluid-conducting internals and / or baffle plates from the heating fluid.
  • the scope of the invention also includes a method for producing tube radiators which optically consist of a plurality of radiator elements arranged next to one another and of at least one two successively arranged rows of tubes are made of vertical heating pipes.
  • the vertical heating pipes are fluid-conductively connected at their opposite ends by high-temperature soldering with pipe connecting pieces of horizontal header segments.
  • the collection tube segments are produced by internal high-pressure forming and thereby advantageously have a conventional Schiederrohroptik.
  • the manifold segments are at least partially fluid-conducting, for example, by welding or soldering together when assembling the radiator.
  • the limb-pipe structure of the manifold segments is produced by an over the length of Sammlerohrsegmente varying cross-section by internal high-pressure forming.
  • the manifold segments are provided with pipe connections for connection to the vertical heating pipes.
  • the collection tube segments are provided with pipe connection piece for at least partially fluid-conducting connection with the underlying manifold segments.
  • the radiator according to the invention is composed of at least two segments (tube registers), which are arranged one behind the other and over corresponding, partially heating fluid-carrying connecting parts 1 n, 2.n, are connected, whereby a serial forced flow of the individual segments is made possible.
  • the aforementioned connecting parts 1.n, 2.n are preferably provided at the ends of the lateral opposite inner sides of the headers 1 and 2 respectively. These can be arranged in the side openings flow tubes, baffle plates, baffle plates with vent holes, etc., which allow either the flow of the heating medium or prevent.
  • Each pipe register consists of 2 headers and the heating pipes in between. According to the invention, the headers do not have a constant cross-section over the entire length, as do conventional tubes.
  • the cross-section of the tubes varies over the length to represent the limb appearance of the radiator.
  • Such pipes can not be produced by a conventional method (welding, drawing). According to the invention, these pipes are therefore produced by the internal high-pressure forming process (IHU).
  • IHU internal high-pressure forming process
  • at least two collection tube designs (header 1, 1 '(front / rear) - central header 2) are provided, which in the Fig. 1 and 2 are shown.
  • a central manifold 2 is required only for more than two-row radiators.
  • the pipe connection piece are designated.
  • the Fig. 3 and 4 each show the assembled upper and lower manifolds of a 4 - row radiator in a perspective view.
  • the headers can be connected by welding or soldering.
  • the individual headers can be made close together laterally, such as in the Fig. 8 shown. But the manifolds can also be spaced apart from each other by lateral pipe connection pieces (1 b, 2 b) or more strongly formed connecting portions 1. n, 2.nb, as it is in Fig. 9 will be shown.
  • the FIGS. 5 to 9 show several possible embodiments and types of complete tubular radiators.
  • the cost-effective high-temperature brazing in a continuous furnace
  • the heating pipes 3 can have any conceivable cross-sectional shape.
  • the Schiederrohroptik the headers and the pipe connection pieces can be formed depending on the shape of the heating tube (round, square, elliptical, etc.).
  • the serial flow of radiators which are made up of at least two sections, brings several advantages over conventional (parallel) radiators flowed through with it.
  • the first row of pipes (facing the room) is first flowed through, followed by the back row (s) of pipe, which decisively improves the sense of well-being.
  • the heating medium is passed through a targeted guide with the aid of baffle plates 4, or flow tube 1.n, 2.n in the front row of the tubular heater and then in the underlying rows of the radiator.
  • the baffle plates 4 can be provided with vent holes if necessary.
