Definitions

  • the invention relates to a plate heat exchanger.
  • plate exchangers are produced by stacking a multiplicity of plates with interposition of seals between successive plates, these seals being open at intervals so as to put intermediate intervals between two plates into communication with intake and intake manifolds. fluid return.
  • the successive intervals are connected in this way alternately to intake and return manifolds conveying a first fluid and intake and return manifolds conveying a second fluid, the term fluid here encompassing all types of liquids and gas, the two fluids exchanging heat energy through the plates during their journey in the intervals between plates.
  • seals limits the field of use of these exchangers, in particular with regard to temperature, pressure and certain fluids, such as corrosive fluids (acids) or solvents.
  • maintaining the plates in a stacked condition necessarily requires providing support plates at the ends of the stack, which are connected to one another by tie rods distributed around the periphery of the exchanger plates.
  • the resistance of the support plates and tie rods is conditioned by the higher of the pressures of the two fluids circulating in the exchanger.
  • each plate is assembled to an adjacent plate by welding along two opposite edges, and to the other adjacent plate along two other opposite edges, so that the circulation of the fluids in the intervals between successive plates must be performed at cross currents.
  • the plates are first welded in pairs along at least two opposite edges, then the pairs thus formed are grouped inside a calender , which is sometimes simply made up of sealing strips welded on one side to another pair of plates, along the same edges and on the other side to another pair of plates, close to the first or not.
  • the present invention provides a plate exchanger comprising a multiplicity of metal plates juxtaposed and defining intervals between them, one interval out of two being intended for the circulation of a first fluid and the other intervals being intended to the circulation of a second fluid substantially parallel to the first, each plate being connected at its periphery to the two adjacent plates in a leaktight manner while providing inlet and outlet orifices for said fluids, characterized in that said plates are assembled in pairs by linear welding in two opposite end zones of the plates of each pair, at least one plate in pairs comprising a wing, at least in one of said end zones and in the vicinity of said weld, folded substantially at right angles and connected in its free marginal zone to a plate opposite a neighboring pair, by linear welding.
  • the exchanger according to the invention consists of a stack of juxtaposed metal plates in the form of! 1> - - so rectangular and six of these plates 10, 11, 12, 13 are shown in FIG. 1, 14 and 15, some of which have been cut transversely so as to highlight the particularities of assembly.
  • the first pair, 10-11 is shown to its anterior edge while the other two pairs have been sectioned along different transverse vertical planes.
  • the plates of the same pair define between them an interval designated by the reference A, and the pairs define between them intervals designated by the reference B.
  • the intervals A are intended for the circulation of a first fluid and the intervals B are intended for the circulation of a second fluid, with the aim of ensuring a heat exchange between them through the plates.
  • the intervals A and B are closed, at least at the top and bottom by the fact that each plate is connected at its periphery to the two adjacent plates, in a sealed manner.
  • the plates of the same pair for example 14-15, are welded together by linear welds 16 and 17 in their upper and lower end zones.
  • these welds can be produced, for example, by electrical welding with a thumbwheel, as will be explained below.
  • the plates have wings 18, 19, 20, 21 connected to their upper and lower end zones, and folded substantially at right angles, which makes it possible to assemble the pairs of plates together.
  • the pairs are assembled side by side, so that the wings 20, 21 of a plate (14) of a first pair (14-15) are arranged edge to edge relative to the wings ( 22, 23) of the plate 13 opposite the neighboring pair (12-13) and the wings are welded to each other (20 and 22, 21 and 23) by a linear weld bead, for example by welding bow.
  • the plates of the same pair (10-11) are also welded to each other along their anterior extreme zone 24, either by electrical welding with a thumbwheel, or by cord arc welding.
  • Fluid inlet and outlet openings to the intervals A are provided in the form of interruptions in the upper linear welds 16 and lower 17.
  • a single orifice 25 has been illustrated in FIG. 1, at the level of the upper weld 16, and in the vicinity of the anterior end zone 24.
  • the other orifice, not shown, is arranged in the vicinity of the posterior end zone, optionally at the level of the upper weld 16 or the lower weld 17.
  • the pairs of plates are devoid of wings at their anterior and posterior end zones, so that there remain free openings between the pairs of plates, which thus constitute the inlet and outlet orifices for the fluid circulating in intervals B.
  • the plates have depressions 26 distributed substantially regularly over the surface of the plates and whose role is multiple.
  • the plates are welded to each other by points at the bottom of the depressions, which prevents - the spacing of the plates when, on the contrary, the fluid pressure prevailing in the intervals A exceeds that which prevails in intervals B.
  • these depressions create obstacles to the flow of the fluid in the intervals A and the turbulences which result from it improve the heat exchanges between this fluid and the plates.
  • depressions can be arranged in regular rows as illustrated, or in staggered rows or according to any predetermined arrangement.
  • the insulated plate 10 illustrated in Figure 2 was obtained in a conventional manner by stamping the depressions 26 and folding the wings square.
  • This plate is then assembled to a second plate 11 by spot welding at the bottom of the depressions 26 ( Figure 3).
  • Weld beads 16, 17 are then produced in the vicinity of the feet of the wings, by electrical welding using knobs 28, 29 (FIG. 4), it being noted that the plates initially spaced from one another ( Figure 3) are forced to move together under the pressure of the knobs. This is made possible by the small thickness of the plates and their small spacing and avoids a prior drilling operation.
  • a first pair of plates (10-11) is then assembled to a second pair of plates (12-13) constituted in the above manner, by presenting the wings of both in edge-to-edge relationship and then by producing a linear weld bead, for example by arc welding.
  • the plates thus assembled form a one-piece assembly with which inlet and outlet manifolds are associated for the fluids circulating in the intervals A and B.
  • a manifold 30 in the form of a rectangular pipe is welded to the perimeter of the front end of the exchanger plates.
  • a similar manifold, not shown, is welded to the perimeter of the rear end of the exchanger plates.
  • a semi-cylindrical manifold 32 is welded transversely to all of the plates, so as to cover all of the orifices 25 for the fluid flowing in the intervals A.
  • the front edge (according to the arrangement of FIG. 8) of the collector 32 is welded to the upper face of the collector 30, and its rear edge is welded to a pseudo-planar and almost continuous surface, formed by the succession of the wings of the plates exchanger. These welds are preferably carried out with the addition of metal so as to provide the required seal.
  • the front edge of the manifold 32 can also be welded to the wings of the exchanger plates, provided that the orifices 25 are formed somewhat behind the front edges 24 of the plates.
  • a wedge 34 in the form of a wedge is introduced between two plates of a pair 1 0-11 so as to prevent the advance of the welding knobs - 28, 29 in the area of the orifice.
  • support plates 36, 38 must be provided in the vicinity of the exchanger plates situated at the ends (FIG. 6). These support plates are juxtaposed, without fastening, the heat exchanger plates so as to allow differential expansion, and are joined to each other by tie rods 4 0, sized and distributed to absorb the forces due to the Pession of the fluid circulating in the intervals B.
  • FIG. 9 only one plate out of two comprises wings 18, 19, the other plates being devoid of wings.
  • the pairs are assembled by welding the wings of a plate directly to the edges of a plate devoid of wings of the neighboring pair.
  • the plates carrying the wings are entirely flat and the plates devoid of wings carry the depressions 26.
  • the plates devoid of wings carry the depressions 26.
  • the plates When assembling in pairs, the plates are placed head to tail, then the pairs are assembled, as before, by welding the edge of the wings to the edge of the facing plates.
  • the wings are extended by a flap 42, and the ends of plates devoid of wings have an extension 44.
  • the flaps and the extensions are welded flat by electric welding with a seam.
  • the exchanger plates are completely flat and during assembly in pairs, is interposed therebetween metallic spacers 4 6 which are spot welded to both plates.
  • the plates are of the corrugation type, the corrugations of one (48) having a different orientation from the corrugations (50) of the adjacent plate.
  • the plates are joined in pairs by seam welding along their edge, as seen above. It is also possible to provide or not to join the two plates by spot welds in the zones where the top of the undulations of one is in contact with the bottom of the undulations of the other, as illustrated by the points P in the figure.
  • the plates are assembled in pairs by linear welding without the addition of metal in two opposite end zones, and that at least one plate in each pair has a wing located in at least one of these extreme zones and in the vicinity of the linear weld, folded back to the square and connected in its free marginal zone to a plate opposite a neighboring pair, by linear weld.
