Definitions

  • the present invention relates to a device for attaching a panel of horizontal or gently sloping heat exchange tubes to vertical tubes or beams provided with longitudinal fins.
  • Such panels have already been fixed using collars formed around the tubes carried and welded to the vertical tubes or beams; or using monobloc saddles placed between the tubes or the support beams and the tubes carried and welded on them; or using spacers formed from two parts sliding one inside the other, one of these parts being welded to vertical tubes or beams: the other part being welded to the carried tubes.
  • Such attachment devices require careful preparation of the panel on the template and possibly a large number of welding operations.
  • the connecting pieces formed between the vertical tubes or beams and the horizontal tubes often have relatively small contact sections with the horizontal tubes, so that they are then poorly cooled by the fluid circulating in them and that it can appear excessive thermal stresses on the part-tube connection which can cause the tube to rupture.
  • there are vibrations in operation in the tube panel there are stress concentrations at the rigid connections between the carried tubes and the support, which can lead to tube ruptures.
  • the object of the present invention is to remedy these drawbacks, and to provide a device for hanging such tube panels which does not require very careful positioning of the tubes on a template, which lends itself to simple and rapid fixing, practically without no welding operation, and which allows the use of relatively simple intermediate parts and not requiring high manufacturing precision.
  • Figure 1 shows in side view a few horizontal tubes of a panel fixed on the shoulders of the fins of a vertical tube, and a part forming a latch and a jumper separate from the device.
  • FIG. 2 is an exploded perspective view of two tube supports, with parts forming a latch and jumpers, corresponding to the upper part of the device in FIG. 1.
  • Figure 3 represents a side view of a few tubes, including two pairs of spacing greater than that of the others, corresponding to different parts of the panel, and the parts forming the corresponding latch.
  • the vertical tube 1 comprises opposite welded vertical fins 2. These fins are cut by punching notches such as 3 t separating shoulders 4 with rim 5 projecting upwards.
  • the latch 6 has a substantially flat upper face 7 on the side facing the vertical support tube, and rising on the other side according to a cylinder with a radius of curvature equal to that of a horizontal tube such as 8, so to oppose a detachment of the horizontal tube towards the outside.
  • the width of the upper face 7 is determined in conjunction with the depth of the notches 2 ′ so that the tubes put in place come into contact with the bottom of the notches.
  • the latch part is provided with a spout 9 separated from the middle part by a hollow 10 of width corresponding to that of the rim 5 of a shoulder 4, so as to be fit exactly on this one.
  • It also includes a vertical sole 11 intended for apply against the rim of the shoulder 4, pierced in its lower part with a rectangular hole 12, and comprising on each side of this hole wings 13 intended to be applied on the two faces of the shoulders 4.
  • These holes 12 are intended to allow the introduction of jumpers 14, which once placed in position come to rest by their legs on the upper periphery of the immediately lower horizontal tube.
  • a lateral rim 15 of these jumpers is sufficiently pronounced to come into abutment on the lower part 16 of the corresponding shoulder, and thus to block the corresponding tube in the event of upward bias which would tend to unhook it during setting in. square.
  • the jumpers 14 are not required to hold the tubes of the panel in place. They can be made of a combustible material at the temperature of the combustion gases coming into contact with the tube panel, and for example of plastic material.
  • FIG. 3 represents a device for hooking tubes similar to that of FIGS. 1 and 2, but in an area where two adjacent tubes have a spacing greater than that of the other tubes, corresponding for example to the limit between two different parts of the panel of tubes.
  • the parts forming a latch 6 are replaced at this height by parts 6A, comprising longer vertical flanges 11A, pressing against the shoulder flange 3A.
  • Jumpers 14, identical to the others, are engaged in the holes 12, identical to those of the other parts forming a latch, of the parts 6A.
  • the invention applies to the attachment of all panels of horizontal or slightly inclined, straight or helically low pitch heat exchange tubes.
