    1408823 Connecting pipes SQUARE SA 9 March 1973 [20 April 1972] 11439/73 Heading F2G [Also in Division F4] A heat exchange tube unit comprises a plurality of parallel flexible thermoplastic tubes 1 held in spaced apart relationship by means of spacer elements 2 each of which is made up of two halves 3 and 4 connected together by pin projections 6 received in aligned bores 7. A number of such tube units are stacked one above the other to form a tube bundle, with adjacent spacer elements 2 of adjacent units being interconnected by means of projections 8 received in bores 9. The tube bundle, in use, extends between tube plates 30 apertured to receive the tube ends. Sealing between the apertures and the tubes may be achieved using rubber grommets 32, Fig. 10A, or by means of an O-ring 36, Fig. 10B, sandwiched between discs 34, 35 welded to opposite sides of each aperture, a metal sleeve 33 being inserted into the end of the tube to prevent it from collapsing. In an alternative embodiment (Fig. 10C, not shown) the tube ends are received in apertures in a cylindrical header (37), the outer surface of the header and the ends of the tubes being coated with a layer of thermoplastic material (38).

    one
    The invention relates to a method of manufacturing a heat exchanger, having an external tube made of a thermoplastic material, and intended for use in it. as a heat exchanger in thermoelectric power plants at low pressures and temperatures.
    There are known methods for manufacturing a heat exchanger by parallelly placing thermoplastic pipes in a distancing plane, striking them at a predetermined level to form a tubular module, winding it into a roll, dividing the module into parts that are installed one above the other in a unit connected to the collectors Ts.
    However, the manufacture of the tubular module takes considerable time, due to the lack of simultaneity between the operations of winding pipes, labeling them with spacer: elements, cutting pipes and winding the latter with elements on a roller.
    The purpose of the invention is to provide ease of transportation and improved manufacturability when using
    pipes with a length of one thousand times their diameter.
    This is achieved by winding the pipes into a roll with fixing its
    5 cov with psseyu made rigid, and the separation of the module into parts is carried out when unwinding the roll.
    FIG. 1 shows a module of
     thermoplastic pipes parallelly spaced in the plane and distanced by the slats; in fig. 2 shows the component parts of the spacer bars; in fig. 3
    6 shows a spacing plate; in fig. 4 shows spacer arms connected to one another to form a bag; in fig. 5 shows a flow chart for obtaining the module shown in FIG. 1, and its winding on the drum using the power plant; in fig. 6 depicts a roller for feeding pipes to the component parts of the spacer bars, which fit into
    movement of the power plant; in fig. 7 shows a stationary comb used to form a module attached to
    power plant; in fig. Figure 8 shows an installation that provides the connection of the component parts of the spacer bars and the spacing of the pipes in the plane in fig. 9 shows MBDUs wound into a roll for the purpose of transportation; in fig. 10th time to get pipe bundles from individual modules; in fig. 11 shows a package of modules with the formation of a tube bundle; Fig. 12- is one of the variants for connecting the ends of the pipes to the manifold; in fig. 13 is another embodiment for connecting pipe ends to a manifold; in fig. 14 - the third option. Connecting the ends of the pipes to the collector; in fig. 15 shows a general view of the heat exchanger manufactured by the proposed method. . The heat exchanger contains pipes 1 of any section, strips 2, provided with grooves 3, pins 4 and centering pins, blind holes. 5, channel bars 6 for forming a frame, support rods 7, tensioners, rods 8, connecting rods 9, strips 10, collector 11, with a distribution plate 12 equipped with sealing elements 13 for pipes, sleeves 14., spring rings 15, 16 : ring 17, thermoplastic material 18. Equipment used to carry out the described method; includes guide comb i roller 19, comb 20, syringe machine 21, conveyor 22, drum 23, npyizhiny 24 with cams 25, springs 26
    with cams 27, arms 28 of frame 29. The method is carried out as follows.
    The method includes the following steps - the manufacture of the pipe module, then the assembly of the modules into a package, both manually and mechanized. can be spliced manually by straps to form a module with the subsequent folding of the latter into a roll for transportation.
    The strips are installed with equal gaps - along the length of the tubes, ensuring parallel tubes and positioning in the same plane. When assembling a heat exchanger, the module package’s height and height is provided with pins 4 and blank 5. The heat exchanger assembly process can be mechanized. from the machine 21, after cooling, are fed to the guide ridge rollers 19, the conveyor
    22, and then on the installation, on which the spacing of the pipes 1 is ensured by the films 2 to form modules, which are then wound onto the drum 23 for the sake of ease of transportation, and the winding can be performed in several places. On the installation, using the spring system 24, 26 and the cams 25, 27, the frames 29 and the components of the strips 2 are moved, and the latter are joined with the next njHM by preloading using the levers 28. The cams 25 and 27 are rotated and the tubes 1 are fed synchronously, at the same time cutting to the required length unwinding .Q from the drum or machine 21 pipes 1 is performed. The modules are stacked one above the other from several drums 23 simultaneously to obtain a heat-exchange surface of the required shape and area, which is fixed forward beam channels 6, CT givae rod yx "and 7, 8, 9, and is attached to the manifold 11. In this sealing pipe ends in a distribution plate 12 is effected by po-
    0 by the force of either the elements 13 or the spring rings 15 and 16 and the rings 17. To prevent deformation of the ends of the pipes, sleeves 14 are used which are installed in the pipes to
    5 module assemblies c. The rings 15 and 16 are attached to the plate 12 by any of the known methods (soldering, using glue, welding, etc.). If the collector is tubular, then
    Q pipes are attached to it along the generatrix via sleeves 14 and thermoplastic material a 1 8.
    The described method allows
    C to reduce the time spent on assembling a heat exchanger from long pipes, by combining a number of operations carried out in a known manner sequentially, as well as to facilitate the transport of tubular
    0 modules, from which a heat exchanger of any surface can be made.
