Definitions

  • the present invention relates to a heat exchanger comprising vertical tubes forming parallel loops between an inlet and an outlet by which they are suspended from a rigid structure, two adjacent vertical sections close to tubes being secured by a fastening device, each section to starting from the central sections comprising a hollow element projecting on its side towards the outside of the bundle and ending in a beak, welded on it according to two generatrices, while the neighboring section more distant from the central sections is provided opposite a similar element, also welded on it according to two generators and also ending in a spout coming to bear on the first element.
  • Document FR-A-1 259 288 has already proposed a device for securing adjacent tubes of an exchanger, comprising a male element welded to one of the two adjacent tubes, and two female elements welded to the other. tube and blocking the male element.
  • Such devices are relatively complex. They require in the case of document FR-A-1 259 288 different parts of complex shapes, and in the case of document US-A-2 809 616 eight parts and six operations of welding by junction device.
  • the object of the present invention is to provide a heat exchanger provided with a device for securing the sections of vertical tubes which transfers the weight of the sections of the central part to the extreme inlet and outlet sections, and which may include a large number of tube loops, without however causing stresses liable to produce deformations, cracks or ruptures in welds, the joining device remaining simple and quick to implement.
  • the heat exchanger according to the invention is characterized in that each element of the securing device comes to bear on the external surface of the adjacent section, in that the element closest to the central sections is provided with a spout oriented downwards, and the adjacent element further away from the central sections of a beak oriented upwards, the beaks of the two elements fitting into each other.
  • each section disposed on the inner side relative to the adjacent section with which it is secured is further provided with a cleat welded to its generatrix, closest to the adjacent section below the lowest point of the element. hollow, and at a sufficiently small distance from the height of the spouts to prevent the dislocation of the hollow elements for securing the two sections.
  • the superheater element comprises three tubes in parallel, forming four loops 5, 6, 7, 8, the sections of inlet tubes represented while being subject to a fixed structure 3 and the sections of tubes outlet shown in 2 to a fixed structure 4.
  • the securing device generally represented at 9, arranged in the upper part of the exchanger, comprises elements for securing adjacent sections, starting from the sections of the central loop, d on the one hand to the left, on the other hand to the right, in order to transmit half the weight of the tubes to the inlet sections, and the other half to the outlet sections.
  • FIGS. 2 and 3 show on a larger scale hollow elements for securing two adjacent tubes 10 and 11.
  • the element 12 is welded to the section of tube 10 by weld beads according to two generatrices 14 and 24. Its oblong internal opening comes into contact along the contour 16 with the adjacent section 11, and has a beak 18 oriented downwards , resting on the upper part of the element 13. The latter is welded to the section 11 by weld beads according to two generatrices 15 and 25. Its internal opening comes into contact with the section 10 along the contour 17, and has a spout 19 oriented upwards, resting on the lower part of the element 12. The edges 20 of the spout 18 and 21 of the spout 19 appear in FIG. 3.
  • a cleat 22 is welded to the tube 10, below the element 13, and close enough to the latter so that it cannot disengage from the element 12, given the height of their spouts 18 and 19.
  • Figure 4 shows in perspective a fastening element before welding on a tube.
  • Generally rectangular in shape it has two flat edges 26, 27, along which it is welded to the corresponding tube, separated by a depression 28 of circular shape and of radius equal to the radius of the tubes, so as to be applied to the tube, and on the other side two flat edges 29, 30, separated by a depression 31 also of circular shape and of the same radius, so as to come to be applied on the adjacent tube. It is also pierced with a. oblong opening 32, and ends downwards with a spout 18.
