Definitions

  • the present invention relates to exchangers and in particular exchangers intended to ensure an exchange thermal between two fluids to be separated one of the other. It relates more particularly to spiral type exchangers produced by winding sheets, in particular of metal sheets. Such a heat exchanger representing the most prior art close is known from document US-4,124,069.
  • exchangers of this type are usually made from two sheets of sheet metal, kept apart by pins, which are wound, the spacing of each of the successive turns of this winding also being obtained by means of spikes, these spikes being formed by a deformation of metal, such as in particular stamping.
  • the spacing generated by the spikes define the respective pressure drops of the two exchanger fluid circuits.
  • this loss load can be achieved by increasing the spacing of the sheets and turns of the winding.
  • This increase in spacing cannot be obtained only by an increase in the height of the pins.
  • Gold the latter is limited by the deformability of the metal used which, of course, is a function of the nature of the material of the leaves, their thickness and base diameter of the picot formed.
  • such an embodiment presents the downside of increasing the importance of obstacles created and opposed to the circulation of the fluid in the two circuits, which increases the loss charge of the exchanger.
  • the object of the present invention is to provide a means for reducing the pressure drop of circuits of a spiral-type exchanger and this in increasing the spacing of the two sheets and / or the spacing of the consecutive turns of the exchanger and this without increasing the base diameter of the spacer pins used.
  • the spacer elements will be formed on the sheets by a deformation process such that in particular a stamping process.
  • the exchanger will include, between internal and / or external spacer elements, undulations arranged substantially transversely along at least part of the width of the leaves.
  • Such an arrangement allows, in the event that, in particular for manufacturing reasons, two elements spacers arranged on a transverse axis of the sheet would not be strictly of the same height, which would cause a variation in the length of the sheet when of the winding, to compensate for this variation in length by a deformation of the corrugation in the direction longitudinal.
  • the spacer elements may be most of frustoconical time, the small bases respective of these truncated cones coming into contact with one with each other and the surface of these allowing compensate for element positioning errors retractors thus produced.
  • the small base of the truncated cone element will be inclined at an angle to the plane of the sheet before winding. Such a provision allows you to self-adjust the height of the spacer elements as set out below.
  • the angle of inclination of the end faces of the spacers from the plane of the sheet will be such that, during the winding, the tension exerted on an outer sheet will effect of dragging the extreme face of the elements spacers of this sheet on the end faces corresponding spreader elements of a sheet internal.
  • FIG. 1 there is shown in a way schematic, respectively before and after winding, a sheet metal strip intended to constitute an exchanger according to the prior art.
  • This ribbon of sheet is cut to length and folded at one of its ends, along its transverse axis xx ', so that it appears in FIG. 1 as being formed of two sheets, namely a top sheet 1 and a lower sheet 2.
  • On the upper sheet 1 we have produced a series of pins 3a which are formed by stamping, from the inside to the outside, and on the lower sheet 2 in the same way, a series of pins 5b which extend from the outside towards inside. Under these conditions, when we wrap this set of two sheets 1 and 2, as well as shown in Figure 2, the pins 5b provide the necessary spacing between sheets 1 and 2 and the pins 3a provide the necessary spacing between the different successive turns.
  • the exchanger according to the invention incorporates the general basic principle, as shown in Figures 3, 4 and 4a, that is to say that it is also made from a top sheet 1 and a lower sheet 2 on which are formed, also by stamping, pins intended to ensure both the spacing of the upper sheet 1 and the lower sheet 2 as the spacing between the turns.
  • Two series of pins are thus produced from sheet 1, namely pins 3a of height h a which extend from the inside towards the outside and pins 3b of height h b which extend from l outside to inside.
  • the spacer pins preferably have the shape of truncated cones, that is to say that they extend from the base of the sheets 1 and 2, inwards and / or inwards. outside of these and terminate in a plate 6, namely plates 6a and 6b as regards the pins produced on the sheet 1 and plates 6a 'and 6b' as regards the pins produced on the sheet 2.
  • the respective spacings 1 of the spikes along the longitudinal axis yy 'of the sheets 1 and 2 to be wound up will be determined, either by calculation or by experience, so that, during the phase of winding, the pins 3b of the upper sheet and the pins 5b of the lower sheet are facing each other so that the spacing e of the sheets 1 and 2 is equal to the sum of the height h b and H b of the pins 3b and 5b which extend inwards and that the spacing E between the turns is equal to the sum of the height h a and H has pins which extend outwards.
  • ripples are intended to give the sheets a capacity of deformation along their axis longitudinal, which compensates for any variation in length of the leaves likely to occur during winding, and in particular those caused by variations in height of the different spikes located on the same substantially transverse axis. Ripples can only be done on one of the two sheets, and they may only extend over part of the width of these.
  • this spacing could be obtained by other means, and in particular using inserts or stops which would fixed on sheets 1 and 2, in particular by welding in the event that these sheets are made of metal or by collage in case they are in matter plastic.
  • the present invention is also advantageous in that it makes it possible to ensure self-adjustment correcting the variations in diameter of the turns, height of spikes, pitches, which appear during winding.
  • the pins 3b and 5b are also formed by deformation of the sheet, in particular by stamping.
  • the pins thus produced are also of overall frustoconical shape, the small base 6b, 6b 'of these, that is to say the contact face of the pins with each other, however being inclined at an angle i relative to the plane of the sheet before winding, as shown in FIG. 5. Under these conditions, when the winding of the different turns is observed, as shown in FIG.
  • slope i formed by the small base of the pins, is large enough to quickly correct the manufacturing tolerances.
