Definitions

  • the invention relates to cross flow heat exchangers.
  • exchangers essentially intended for heat exchanges between gas flows, in particular air flows, usually consist of an alternating stack of substantially square exchange plates, and corrugated spacer plates, of the same shape, the directions of the grooves constituting the undulations of these plates being alternately arranged in one direction and in the perpendicular direction, that is to say alternately in the two directions of the cross flows.
  • the facing edges of two successive exchange plates which are parallel to the direction of the grooves of the spacer plate included between these two exchange plates must be connected to each other in a substantially sealed manner.
  • This sealed connection of the edges can be achieved by any suitable means, for example by welding or soldering as in the case of the US patent. 2,959,401. It can also be obtained by simply folding the edge of the underlying plate over the edge of the overlying plate, so that, over at least part of the width of this folded edge, the spacer plate between the two plates considered exchange is clamped between the underlying plate and this rim, and in addition this rim is pressed on the overlying plate by the following spacer plate which necessarily covers it. As a result, the folding of the two opposite parallel edges of each exchange plate must be completed before each new spacer plate and each exchange plate can be placed. It is therefore necessary to alternate the folding operations and the operations for placing the components of the stack, which complicates the manufacturing process. In addition, the sealing of the edges by simple covering is effective only if the metal used for the exchange plates has a sufficient thickness, for example, from 0.05 to 0.25 mm as in patent FR 2,365. 092.
  • the object of the invention is to eliminate all the above drawbacks, that is to say to increase the efficiency of the exchange and reduce the amount of material used, by allowing the use of extra sheets. thin while achieving perfect sealing of the edges without significant overlap, and also to reduce the amount of labor required for manufacturing by allowing the various components to be stacked at once, then in a second stage sealing edges at various levels of the stack.
  • each exchange plate is not square, but rectangular, and notched in the four angles, in a known manner, but asymmetrically so that after folding perpendicularly and in the same direction over a certain width of the two edges parallel to the short sides, the two lines of parallel folds thus obtained and the two other edges which are perpendicular to them are substantially inscribed in a square with symmetrical notches.
  • the corrugated spacer plates are not square but rectangular with a width equal to the distance between the edges of two notches increased by twice a certain offset, and a length equal to the width increased in turn by double this same offset, the assembly being mounted by simple alternating and crossed stacking of the various components, exchange plates and spacer plates, between four corner profiles which comprise, in the direction of the stacking, four dihedral angle entering between five projecting edges , the two extreme re-entering angles used for guiding the angles formed by each side of the square with the corresponding notch, and the two intermediate re-entering angles used for guiding and precisely positioning the corresponding angles of the various spacer plates.
  • the method provides for carrying out, preferably continuously, and successively at each level, a coating of glue on the internal faces of the flanges folded vertically and their folding as well as their pressing over the corresponding edge of the plate. overlying exchange, the width of these flanges having been determined for this purpose so that when folded inward it does not exceed the outer contours of the spacer plates positioned by the corner profiles.
  • the surfaces of said sections facing outwards from the stack are preferably striated asymmetrically and in a complementary manner so as to be able to fit together after one or more rotation of 90 ° in order to facilitate the grouping of several modules, and also a corner groove with re-entrant profile allowing the assembly of a cover profile, single or multiple.
  • an ultra-thin metal generally aluminum, laminated to thicknesses between 0.02 and 0.04 mm, in sheets or strip.
  • y cut rectangular sheets whose long sides correspond to the outline 1 in figs. 1 and 2, and the short sides of which correspond to the contour 2a shown in phantom in FIG. 1
  • the end flanges 2b of the length of the rectangle are folded perpendicularly upwards, for example upwards, around the lines of piliure 5, the initial edge 2a then coming in 2, and this so that the two lines of parallel folds.
  • corrugated spacer plates 7 of rectangular shape are also produced with the successive grooves of the corrugations arranged parallel to the short sides.
  • the width of each of the spacer plates 7, consequently measured in the direction of the grooves is equal to the distance between two parallel edges 4 of the facing notches, increased by twice a certain offset d.
  • the length of these spacer plates corresponds to its width, increased in turn by twice this same offset d. It follows that between the short side 8 of the spacer plate 7 and the fold line 5 adjacent, there remains a width 1 which is equal to the length of side 3 of the notch (or side 4 limited to the fold line 5) reduced by twice the distance d as shown in fig. 1.
  • the width of the rim 2b is chosen to be less than or at most equal to the width 1 thus calculated of such so that when the flange is folded down, the glued part can be pressed without crushing the end 8 of the spacer plate 7 between the two exchange plates concerned by this folding, and moreover, without being hampered by the end 9 corresponding to the long side of the spacer plate immediately above since there is an additional clearance d between the two edges 8 and 9.
  • exchange plate 6 and spacer plate 7, we proceed according to the invention to their simple stacking, without for the moment taking care of the connection.
  • each of the edges 1 of one of the plates 6 is inserted between the two vertical edges 2b starting from the fold lines 5 and is therefore in principle positioned in one direction but can slide in the direction of these fold lines.
  • the successive spacer plates 7 have more freedom and can both slide in both directions and also pivot in their plane.
  • corner profiles are used, designated as a whole by 10, and which comprise on the side of the stack, a broken line profiling 11, 12, 13, 14, 15, 14, 13, 12, 11 comprising alternately four dihedral angles entering 12, 14, 14 and 12 comprised between five projecting edges 11, 13, 15, 13, 11.
  • the assembly is intended to be placed as shown in FIG. 1, that is to say that the re-entrant angles 12 serve to center for each exchange plate the angles between the edge 4 of the notch and the fold line 5, or the angle between the edge 3 and the edge 1 , the latter in turn engaging in the rim 2b of the immediately lower plate.
  • the two re-entrant angles 14 serve to center the alternating angles of the spacer plates 7 respectively in one direction and in the other direction.
  • the sections 10 can advantageously be made of extruded light alloy, and to avoid giving their walls excessive thicknesses, it is advantageous according to the invention to provide two deep grooves 16 which each open into the bottom of one of the angles 14 , the latter being in this virtual case, that is to say materialized only by the extension of the adjacent faces. These grooves are preferably extended until the edges 11 and 12 are aligned as shown in the figures.
  • each of the corner profiles 10 has at its external angle a groove 19 with a re-entrant profile, preferably of substantially square section as shown in FIGS. 1 and 2 to allow the insertion by sliding of a cover profile 20 in the form of an angle iron internally comprising a rib 21 with a substantially carved bulge coming to fill the groove 19.
  • each of the sections 10, cut to a length corresponding to the height desired for the exchanger module, is machined at its two ends so as to allow assembly with an end plate 22 terminating the module.
  • a mixed line P the mean plane of the ridges 17, 18, or if one prefers the primitive plane according to the teminology of the gear teeth.
  • the outer walls 23 of the profile 10 are degreased with a strawberry over a height corresponding to the height of the plate 22, and over a depth corresponding at least to the thickness of the metal sheet constituting the plate 22 from the mean planes P , and in addition each of the two plates 22 is notched at each of its four angles as shown at 24 in FIG. 2, that is to say along the section of the external contour of the degreased end of the profile 10, with in addition a clearance 25 in the angle for the passage of the swollen rib 21 of the covering profile 20.
  • each of the ends of the sections 10 is also machined over a length corresponding to the height of the plates 22, in the form of a saw cut 26, visible only in FIG. 1, and which releases on this height the external walls 27 of the profile opposite with the edges 3 and 4 of the corner grudgeages.
  • a very simple tool comprising a carriage moving longitudinally along each fold line 5 and carrying a nozzle 30 for injecting glue, hot or cold, whose jet 31 is directed towards the inner face of the vertical edges 2b comprised between the fold lines 5 and the edges 2, and also a profiled presser 32 comprising a lower face 33, for example flat, and an upper face 34 of progressive shape , for example helical, to evolve from a substantially vertical section following the above-mentioned vertical rim 2b, to a substantially horizontal section pressing this rim 2b in the folded state on the surface 33 with interposition of the rest of the plate, below the fold line 5, and the unfolded edge 1b of the plate 6 immediately above.
  • the upper part 34 is for example movable relative to the part 32 and pressed against the latter using elastic means not shown.
  • the finishing therefore consists simply in moving this carriage along a fold line 5, and starting again on each of the edges and each of the levels.
  • the stack ends at the upper part by another plate 22, not shown, similarly fixed by each of its angles to the upper ends of the profiles 10.
  • the tool profiles have on their side opposite the stack the same broken line profile exposed above and which cor corresponds to that of the final profile.
  • these tool profiles can be partially mobile to facilitate the operation of the gluing carriage. The subsequent positioning of the final sections 10 and the upper plate 22 then poses no difficulty.
  • the modules thus produced can be used in isolation.
  • a covering profile 20 of the type described above it is possible to mount in each of the angles a covering profile 20 of the type described above and insert, between the wings 35 of these profiles and the grooved faces 17 of the facing walls 23, a protective mesh which is automatically held by these wings.
