Definitions
- the present invention relates to exchangers and in particular exchangers intended to ensure a heat exchange between two fluids to be separated from each other. It relates more particularly to spiral type exchangers produced by winding sheets, in particular of metal sheets.
- exchangers of this type generally consist of two sheets of sheet metal, held apart by pins, which are wound, the spacing of each of the successive turns of this winding also being obtained by means of pins, these pins being formed by a deformation of metal, such as in particular a stamping. After winding, the edges of the sheets are welded so as to create two independent fluid circuits, namely a first circuit between the two sheets and a second circuit between the various turns of the winding. It is understood that the spacing generated by the pins defines the respective pressure losses of the two fluid circuits of the exchanger. For certain applications, it is advantageous to reduce this pressure drop, which can be obtained by increasing the spacing of the sheets and the turns of the winding.
- the present invention aims to provide a means for reducing the pressure drop circuits of a coil type exchanger and this by increasing the spacing of the two sheets 1 and / or 1 'spacing of consecutive turns of one heat exchanger and this without increasing the base diameter of the spacer pins used.
- the present invention thus relates to a spiral-type exchanger, consisting of two nested fluid circuits, namely a first circuit formed by the space between two separated sheets which are wound on themselves and a second circuit formed by 1 space between the successive turns of this winding, characterized in that: the two sheets comprise, on their opposite faces, internal spacer elements and / or on their opposite faces, external spacer elements, - These internal and external spacer elements are arranged, along the longitudinal axis of the sheets, in such a way that once the sheets are wound, the internal and external spacer elements of a sheet come to bear on the internal and external spacer elements corresponding to the other sheet, the end face of at least one of two supporting spacer elements is generally flat.
- the spacer elements will be formed on the sheets by a deformation process such as in particular a stamping process.
- the exchanger will comprise, between the internal and / or external spacer elements, corrugations arranged substantially transversely along at least part of the width of the sheets.
- the exchanger may be most of the time of frustoconical shape, the respective small bases of these truncated cones coming into contact with each other and the surface of these allowing to compensate for the positioning errors of the spacer elements thus produced.
- the small base of the truncated cone element will be inclined at an angle relative to the plane of the sheet before it is rolled up. Such an arrangement enables self-adjusting of the height of the spacer elements as described below.
- the angle of inclination of the end faces of the spacer elements with respect to the plane of the sheet will be such that, during winding, the tension which is exerted on an external sheet will have the effect of causing the end face to slide. spacer elements of this sheet on the corresponding end faces of the spacer elements of an inner sheet.
- FIG. 1 is a schematic perspective view of a folded sheet of sheet provided with spacer pins according to the prior art, before the winding step.
- FIG. 1a is an alternative embodiment of the invention in which the sheets are provided with transverse corrugations arranged between the spacer elements.
- Figure 2 is a schematic cross-sectional view of the sheet metal sheet according to the prior art shown in Figure 1 after the winding step.
- Figure 3 is a longitudinal sectional perspective view of two sheets intended to constitute a heat exchanger according to the invention before the winding step.
- Figure 3a is a longitudinal sectional perspective view of two sheets intended to constitute a heat exchanger according to the invention before the winding step and which are provided with the corrugations shown in Figure la.
- FIG. 4 is a schematic view in cross section of an exchanger according to the invention produced from the metal sheets, shown in FIG. 3.
- FIG. 4a is an enlarged partial sectional view of an alternative embodiment of part of the winding shown in FIG. 4.
- Figure 5 is a variant in longitudinal section of two sheets before winding illustrating an alternative embodiment of the invention.
- FIG. 5a is an enlarged cross-sectional view of the variant embodiment of the invention shown in FIG. 5.
- FIG. 6 is an enlarged partial section view of an alternative embodiment of part of the winding shown in FIG. 4.
- FIG. 1 there is shown schematically, respectively before and after winding, a sheet metal strip intended to constitute an exchanger according to one prior art.
- This sheet metal strip 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 from two sheets, namely an upper sheet 1 and a lower sheet 2.
- On the upper sheet 1 a series of pins 3a have been produced which are formed by stamping, from the inside to the outside, and on the lower sheet 2, a series has been formed in the same way pins 5b which extend from the outside inwards. Under these conditions, when this assembly of the two sheets 1 and 2 is wound, as shown in FIG. 2, the pins 5b provide the necessary spacing between the sheets 1 and 2 and the pins 3a provide the necessary spacing between the different successive turns.
- the exchanger according to the invention takes up the general basic principle, as shown in FIGS. 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 also ensure well the spacing of the upper sheet 1 and the lower sheet 2 than the spacing between the turns. Is thus achieved, from the sheet 1 two sets of spikes, namely the pins 3a of height h which extend from one inside to one outside and the pins 3b of height h b which extend from one '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 1 and 6b ′ as regards the pins produced on the sheet 2.
- the respective spacings 1 of the pins along the longitudinal axis yy 1 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 distance E between the turns is equal to the sum of the height h a and H has pins which extend outwards.
- the present invention is also advantageous in that 'It ensures self-adjustment correcting variations in the diameter of the turns, the height of the pins, the pitch, which manifests 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 'thereof, that is to say the contact face of the pins with each other, being however inclined at an angle i relative to the plane of the sheet before winding, as shown in Figure 5.
- the pins belonging to the outer surface of two consecutive turns come into contact, by their respective inclined bases 6b and 6b '.
- the spacing of the sheets increases the diameter of the winding also increases, so that the top of the pin of the outer sheet 2 is offset from the apex of the pin of the lower plate 1 due to the increase in circumference.
- the outer sheet 2 then approaches the lower sheet 1 until the spacing becomes equal to that which existed at the start of winding.
- the slope i formed by the small base of the pins, is large enough to quickly correct the manufacturing tolerances.
