Definitions

  • the invention relates to a heat exchanger of modular structure, intended more particularly for carrying out 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 limited due to the fact that, for production reasons, 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.
  • US-A-1,766,283 describes a structure usable for regenerators and comprising in combination a plurality of horizontal alignments of bricks extending perpendicular to each other at adjacent levels, the bricks of each alignment being provided with notches used to prevent the displacement of bricks from the adjacent alignment.
  • US-A-1,670,127 describes a heat exchanger structure formed by series of bars provided with notches or perforations, these bars being juxtaposed and superimposed in such a way that the notches or the perforations are aligned to form passages for the fluids to be put in heat exchange relation.
  • the series of bars are not embedded one above the other.
  • the problem that the invention aims to solve consists in providing a heat exchanger having a particular modular structure, making it possible in particular to delimit separate circulation spaces for the fluids to be put into heat exchange relation, the various constituent elements being built-in of joined together.
  • heat exchangers of the invention are modular structures (produced by a simple assembly of elements) allows easy adaptation to the geometric requirements encountered by the user, in particular facilitating its insertion 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 heat exchanges with condensation.
  • 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 device of the invention also has a high specific heat exchange surface.
  • the heat exchange structures according to the invention can be used to produce both exchanger bodies with two fluids circulating in parallel currents (co-current or counter-current) or in crossed currents, as well as the heads for supplying and the departure of fluids.
  • the invention proposes a heat exchanger for the circulation of at least two fluids in heat exchange relation comprising at least one zone of modular structure essentially constituted by a stack of trellises which can be built one above the other in a contiguous manner and each formed by an intersection of two series of lamellae, each lamella being formed in one piece over its entire length, the two series of lamellae being joined together by mutual engagement of the lamellae, parallel to each other, from the first series and lamellae, parallel to each other, of the second series, at the notches formed on one of the edges (for example upper) of the lamellae of the first series and on the opposite edge (for example lower) of the lamellae of the second series, said stack creating spaces for the circulation of at least two fluids in heat exchange relationship.

  • a first heat exchange structure essentially consists of a stack of lattices (or grids) which can be built one above the other, and each formed by an intertwining of two series of lamellae, assembled by mutual engagement of each lamellae of a series by the lamellae of the other.
  • the lamellae of the first series, parallel to each other, consist of so-called “solid” lamellae, that is to say comprising only, on one of their edges, the notches necessary for straddling with the lamellae of the second series : said strips of the second series are mutually parallel and preferably arranged perpendicular to the strips of the first series; as the case may be, they may consist of "solid” strips like those of the first series, or of so-called “perforated” strips, that is to say comprising in addition to the notches necessary for straddling with the strips of the first series, on one of their edges, recesses formed in some of the solid parts of the strips delimited by two consecutive notches, said recesses being formed for example in one in two of these solid parts.
  • the stacking of the mesh creates circulation spaces for at least two fluids in heat exchange relationship.

If we consider the trellis (or grid) in a horizontal position, the two series of slats 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 edge, equal to each other. These dihedral angles are preferably 90 °.

They can also consist of several disjointed recesses on each strip, one or more of which may or may not open on one edge or on both edges of the strip. FIGS. 4A to 4D show different forms and particular arrangements of these recesses.

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 has shown two lattices each formed of a small number of lamellae, but it is understood that a stack of lattices constituting a heat exchange zone according to the The invention can consist of a large number of superimposed trellises from ten to several hundred and that each trellis can comprise a large number of interlaced lamellae (from ten to several hundred).

  • the respective heights of the slats 5 and 6 and the respective depths of the notches 9 made in the slats 5 and the notches 10 made in the slats 6 are chosen so that the bottoms of said notches 9 and 10, coming into contact when the two series of lamellae 5 and 6 are mounted, limit the mutual overlap of said lamellae so that, for example, the edges of the perforated lamellas 6 opposite the edges where the notches 10 are formed located in the innermost plane (recessed) of the underside of the trellis 2; while the edges of the solid strips 5 opposite the edges where the notches 9 are formed are located in the innermost plane (set back) of the upper face of the same trellis 2.

  • the characteristics defined above reflect the fact that the different stacked trellises fit into one another and that, in this embedding, the projecting (or hollow) parts of one of the faces of a trellis of the first type come into contact with the counterpart hollow (or projecting) parts of the opposite face of the trellis of the second type.

  • the stack of perforated strips creates on the one hand, continuous partitions, when we consider the superimposition of the solid parts of said perforated lamellae, and on the other hand, perforated partition flaps, when we consider the superposition of the perforated parts of said perforated lamellae, the continuous partition flaps alternating with the perforated partition flaps, each section partition of one of the two types being separated from the adjoining partition wall, of the other type, by a continuous adjacent partition corresponding to the superposition of solid strips.
  • the partitions described above therefore determine two kinds of spaces for the circulation of fluids which it is desired to put in heat exchange relation. Indeed, all the solid partitions, formed by the superposition of the solid strips, and parallel to each other, separate spaces which, with respect to the whole of the exchange structure (the stack of lattices), appear as slices. Due to the alternation of solid panels and perforated panels on the partitions formed by superposition of the perforated lamellae, 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 openings of the sections traversed by the second fluid on the faces of the stack intended for the entry and exit of said second fluid are made de facto by the recesses in the perforated lamellae constituting said faces.
  • the heat exchanger structure as described above can constitute the exchanger body of an exchanger intended for the circulation of 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.

But. Unlike the first embodiment described, the two series of strips, the interlacing of which forms each of the lattices, are both made up of solid strips.

  • 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).
  • the distribution of the channels intended for the circulation of the first fluid and those intended for the circulation of the second fluid can be chosen in such a way that, with the exception of the channels adjoining the external walls of the exchange zone, each channel traversed by one of the two fluids is contiguous with at least two channels traversed by the other fluid.
