Definitions

  • the invention relates to a heat exchange device of modular structure, intended more particularly for carrying out a heat exchange between several fluids, in particular between two gases.
  • Tubular and shell-and-tube heat exchangers are known.
  • one of the fluids participating in the exchange passes through the tubes, the other fluid passes around the tubes in the shell.
  • the exchange surface per unit volume, known as the specific surface, which it is possible to obtain by means of such exchangers is generally li. mitée the fact that, for reasons of realization, it is difficult to reduce the diameter of the tubes and the spacing between tubes below a value of the order of 1 cm.
  • Plate heat exchangers make it possible to obtain larger specific exchange surfaces.
  • the fluids participating in the exchange circulate on either side of the different plates but the specific surface is also limited by the need not to reduce the spacing between plates too much.
  • heat exchangers consisting of stacks of perforated sheets, juxtaposed so as to obtain, by superposition of the perforations, channels some of which can be traversed by a relatively hot fluid, others by a relatively cold fluid, the transfer thermal between the channels being provided by conduction through the material forming at least part of said sheets.
  • Heat exchangers are most often made of metallic materials. In cases where condensation occurs during heat exchange, such as in the case of heat recovery from fumes from a heating boiler, these materials have the disadvantage of being easily corroded.
  • the modular structure of the exchange zone could also essentially consist of a stack of interlocking series of lamellae, joined together by mutual engagement of the lamellae, parallel to each other, in series with the lamellae , parallel to each other, of the consecutive series, at the level of notches formed on the two edges of each lamella, facing each other: said stacking of series of lamellae creating spaces for the circulation of at least two fluids in heat exchange relationship.
  • the device thus described produced by a simple assembly of elements, allowed easy adaptation to the geometric requirements. countered by the user, in particular by facilitating its integration into existing systems.
  • the possibility of making this device using a wide variety of materials also makes it easy to adapt it to the nature of the fluids involved in the heat exchange, in particular in cases where corrosion is to be feared, for example in exchanges thermal with condensation.
  • the device thus described also had a high specific heat exchange surface.
  • the heat exchange structures of the previous application could be used to produce both exchangers bodies with two fluids circulating in parallel currents (co-current or counter-current) or in cross currents, as heads for the supply and the departure of fluids.
  • a heat exchange device comprises a zone in which at least two fluids in heat exchange relation circulate and means for the supply and departure of said fluids, this zone of modular structure being essentially constituted by a stack of lattices joined together and made up each of two series of intersecting partitions, this em pillar creating spaces for the circulation of said fluids, each trellis constituting a module being further designed in such a way that, on each of its faces, the edges of the partitions of one of the two series are, over at least part of their length , projecting from the plane formed by the edges, at least partially set back, of the partitions of the other series, the stacking of the lattice being produced by bringing opposite the projecting edges of a series of partitions on a faces of any lattice of the stack with the recessed edges of the corresponding series of partitions on the opposite face of the adjacent lattice, the height of emergence of said projecting edges and the depth of depression of said recessed edges coming from opposite in the
  • Each trellis is advantageously produced by molding a solidifiable material and in particular using an injection molding process, in particular if the material used for the manufacture of the trellis is a light alloy or a thermoplastic material, or by simple mold casting if this material is thermosetting.
  • the term "lattice” designates a grid, formed by an intersection of solid partitions of a first series, parallel to each other, with partitions of a second series full or perforated, parallel to each other. If we consider the trellis (or grid) in a horizontal position, the two series of partitions are placed in two series of vertical planes parallel to each other, each plane of one of the two series intersecting the planes of the other series according to dihedral angles of vertical stop, equal to each other. These dihedral angles are preferably 90 °.
  • the first embodiment of a structure according to the invention illustrated by FIGS. 1, 2, 3 and 4A to 4D can correspond to an exchange zone in which two fluids can circulate in crossed currents.
  • a first type trellis 1 comprises two series of intersecting partitions comprising a series of solid partitions 3 and a series of perforated partitions 4, for example of the same height, which are arranged in two different levels.
  • the openwork partitions 4 have recesses or notches 4A which can have any shape; they can be circular, square, rectangular, etc ... they can lead, or not, on one of the edges of the partition. They can also consist of several disjointed recesses on each partition, one or more of which may or may not lead to one edge or to both edges of the partition.
  • FIG. 1 Also shown in FIG. 1 is a trellis of a second type 2, also comprising two series of intersecting partitions comprising a series of solid partitions 5 and a series of perforated partitions 6, for example of the same height, which are arranged at two different levels, these partitions 5 and 6 having the same thickness and the same spacing as the partitions 3 and 4 respectively.
  • the partitions 3 of a first type 1 trellis are adapted to fit into their lower part in notches formed by the partitions 6 of a type 2 trellis, the partitions 5 of which form notches receiving the partitions at their lower part 4 of a second type 1 trellis.
  • the recesses or notches 6A of the perforated partitions 6 of the trellis 2 can have various shapes and arrangements (FIG. 2).
  • the heat exchange structure according to the invention is formed by an alternating stack of type 1 and type 2 trellises, the underside of each type 1 trellis fitting in (as it appears in FIG. 1) on the upper face of a type 2 trellis. Likewise, the lower face of each type 2 trellis must be able to be embedded on the upper face of a type 1 trellis, not shown in FIG. 1.
  • FIG. 1 only shows two lattices, each of which has only a small number of partitions, but it is understood that a stack of lattices constituting a heat exchange zone according to the invention may consist of a large number of superimposed trellises of ten to several hundreds and that each trellis can include a large number of intersecting partitions (from ten to several hundred).
  • the depression of the hollow (lower) edges of the series of partitions 6 of the trellis 2 is made to correspond to the emergence of the (upper) protruding edges of the series of partitions 4 of a type 1 trellis located below the type 2 trellis.
  • Figure 2 corresponds to a section through a plane II parallel to the partitions 4 and 6 of the two trellis of Figure 1 in their assembly position and similarly Figure 3 corresponds to a section through a plane 111 parallel to the partitions 3 and 5 of the two trellis of Figure 1 in their assembly position.
  • FIGS. 4A to 4D correspond to sections similar to that of FIG. 2, but for other forms of the recesses 4A, 6A of the partitions 4 and 6.
  • the different stacked trellises fit into one another and, in this embedding, the protruding (or recessed) parts of one of the faces of a trellis of the first type come into contact with the homologous hollow (or projecting) parts of the opposite face of the second type of trellis.
  • the stack of perforated partitions 4 and 6, the planes of which, parallel to one another, intersect the planes formed by the stack of solid partitions 3 and 5, for example at right angles, creates on the one hand, continuous sections of partition , when we consider the superimposition of the solid parts of said perforated partitions, and on the other hand, perforated partition sections, when we consider the superposition of the perforated parts of said perforated partitions, the continuous partition sections alternating with the sections of openwork partition, each partition wall of one of the two types being separated from the neighboring partition wall of the other type, by a continuous adjacent partition corresponding to the superposition of solid partitions.
  • the partitions described above therefore determine two kinds of spaces for the circulation of the fluids which it is desired to put in heat exchange relation. Indeed, all the solid walls, formed by the superposition of the solid partitions, and parallel between they separate spaces which, in relation to the whole of the exchange structure (the lattice stack), appear as slices. Due to the alternation of solid panels and perforated panels on the walls formed by superposition of the perforated partitions, the sections defined above are, alternately, of two different types. Some are subdivided into channels, of rectangular or square section for example, separated by solid sections; the other sections are not subdivided into separate channels, owing to the fact that the openings in the openwork sections constitute as many passages from one channel to the neighboring channel.
  • the separate channels delimited in the various spaces (or sections) are generally traversed by a first fluid participating in the heat exchange.
  • the fluid then circulates in a direction parallel to the planes of the solid partitions constituting the exchange zone.
  • a second fluid is circulated in the spaces (or sections) not subdivided into separate channels.
  • the fluid can pass through each of these sections right through using the communication passages formed by the recesses it meets, the remains of the solid parts surrounding the recesses constituting fins or baffles.
  • the fluid circulates in an overall direction substantially perpendicular to the openwork partitions and parallel to the solid partitions. In these conditions. the two fluids circulate in crossed currents.
  • the ends of the spaces (or sections) traversed by the second fluid situated on the faces of the stack intended for the entry and the exit of the first fluid are closed for example by end plates (such as 11 and 12, FIG. 1 ) coming to fit on the first (and the last) lattice of the stack, these plates covering one space out of two, the spaces remaining open corresponding to the inlet (or to the outlet) of said first fluid.
  • the openings of the wafers traversed by the second fluid on the faces of the stack intended for entry and exit of said second fluid are made de facto by the recesses of the perforated partitions constituting said faces.
  • the heat exchanger structure as described above can constitute the exchange body of an exchanger intended for the circulation of the two fluids in cross currents, one of the fluids, for example fumes , traversing the separate channels from top to bottom or from bottom to top and the other fluid, for example air to be heated, then circulating from a side face to the opposite face.
  • the means for supplying and leaving the fluids may consist of conventional means, in particular cylindrical conduits which are suitably connected to the faces of the exchange body through which must enter (or exit) each of the fluids concerned. These means have not been illustrated in FIG. 1.
  • a second embodiment of the first heat exchange structure according to the invention described above can consist essentially, like the first mode described, in a stack of lattices (or grids) built in one above the other, and each formed of two series of intersecting partitions.
  • the two series of intersecting partitions, each forming a trellis are both made of solid partitions.
  • the description of this second embodiment will therefore be similar to that of the first, provided that the "perforated" partitions are replaced by "full" partitions.
  • FIGS. 6A and 6B show possible arrangements for the channels traversed by the two fluids.
  • the structure considered is constituted by alternating stacking of any number of trellises such as 13 and 14.
  • the embedding of these trellises is carried out in the same manner as for the first embodiment described: the projecting parts are made to correspond (or recessed) of a trellis, for example of the first type (such as 13) with the recessed (or protruding) parts of a trellis of the second type (such as 14) located below or above said trellis of the first type.
  • the spaces will no longer be distinguished (or sections) divided into separate channels and the spaces (or sections) not subdivided into separate channels but comprising passageways that are the recesses of the perforated partitions.
  • the stack of trellises consisting only of solid partitions will only comprise channels, all separated from one another by the solid partitions resulting from the superposition of the solid parts of the homologous partitions.
  • This structure can constitute the body of a heat exchanger in which for example two fluids circulate in parallel currents (in co-currents or against the current).
  • each channel A traversed by one of the two fluids is contiguous with at least two channels B traversed by the other fluid. Examples of such distributions are given in Figures 6A and 6B.
  • a particularly advantageous aspect of the invention consists in having the exchange zone open up at each of its ends on heads for supplying and leaving fluids each designed analogously to the first embodiment described above (cross-flow circulation).
  • FIG. 7 shows in perspective a heat exchanger formed of a central body and two collectors at its ends; and FIGS. 8A, 8B and 8C schematically show several possible relative arrangements for the central body and the two manifolds.
  • the heat exchange device 15 comprises a central body 16 and two collectors 17 and 18.
  • the central body 16 is in the form of a parallelepiped with a rectangular or square base formed, by the stacking of the trellis which constitute it, of a determined number of rows of section channels in the shape of a parallelogram (for example rhombus, rectangle or square), each row comprising a determined number of channels.

  • the spaces traversed by said second fluid are, at the junction of the manifold 17 with the central body 16, in communication with the corresponding rows of channels, the plates such as 12 (shown in FIG. 1) being, in the present case, well heard omitted.
