Definitions

  • the subject of the invention is a heat exchanger with welded plates. It also relates to a plate intended to be used in this exchanger.
  • the invention relates to the technical field of heat exchangers made by the juxtaposition of plates welded together and defining cold fluid circuits and hot interpenetrating according to the preamble of claim 1.
  • WO93 / 22608 describes such a heat exchanger.
  • Plate heat exchangers are well known to those skilled in the art. These exchangers generally ensure the transfer of frigories or calories between a cold fluid and a hot fluid, without said fluids come into contact. For example, these exchangers can be used to ensure the condensation of steam by contacting a cold source. Such exchangers are for example disclosed in the patent documents WO 93/22608 (FERNANDEZ ) and FR 2.562.997 (VICARB ).
  • the exchanger described in the document WO 93/22608 includes (the references in parentheses apply to this document) a closed enclosure within which are arranged ribbed welded plates (1, 18, 19) defining between them interpenetrating independent circuits in which are intended to to circulate fluids.
  • the plaques (1, 18, 19) are welded together in two cassette form.
  • the side walls (39) delimiting the enclosure, are fixed on vertical spars (10) inserted in gutters (16).
  • the plates (1) are directly welded to one face of the gutters (16).
  • the plates (18, 19) are welded to lights (25) made on a vertical wall (24) joining two gutters (16).
  • the method of fixing the plates (1, 18, 19) described in the document WO 93/22608 has a number of disadvantages.
  • the first embodiment there are important mounting constraints because the plates (1, 18, 19) must be perfectly positioned on the gutters (16) and be welded with great precision.
  • the welds take all the mechanical stresses and significant thermal expansions, so that these welds can quickly break and generate sealing problems (and therefore a drop in the efficiency of the exchanger) between the two fluid circuits.
  • these welds are directly exposed to fluids circulating in the device.
  • the use of the vertical walls (24) unnecessarily increases the size of the enclosure.
  • VICARB The document FR 2.562.997 (VICARB ) describes an exchanger (the references in parentheses apply to this document) consisting of ribbed plates (20) stacked inside a closed enclosure. These plates (20) are held juxtaposed one above the other by welding and stiffened by means of four longitudinal rigid longitudinal members (3) supporting the lateral walls (5, 6, 7, 8) of the pregnant. These side walls form (5, 6, 7, 8), in association with the longitudinal members (3), independent chambers for each of the fluids. Each plate (20) comprises ribs configured so as to form, during their stacking, independent and interpenetrating conduits, in which the hot and cold fluids circulate.
  • the plates (20) comprise in each corner, a vertical edge (25, 26, 27, 28) for fixing them, by welding, on the longitudinal members (3).
  • the method of fixing the plates (20) described in the document FR 2.562.997 also has many disadvantages.
  • the first is that the formation of the vertical ridges (25, 26, 27, 28) requires a specific stamping of the plates (20) made so that the edges are turned alternately in the opposite direction of 90 ° to form said edges. This particular shape makes it difficult to weld the plates (20) together.
  • a second disadvantage lies in the fact that the plates (20) must have limited surfaces (in practice at best 75 cm x 75 cm) so that said plates and the side walls (5, 6, 7, 8) of the enclosure do not undergo too much pressure which could degrade the rigidity and mechanical strength of the exchanger.
  • the main technical problem that the invention aims to solve is to improve the assembly and maintenance of the plates inside the enclosure.
  • Another object of the invention is to provide a heat exchanger making the design simpler than that of known exchangers of the prior art.
  • Yet another object of the invention is to propose an exchanger which can have a greater exchange surface than that of the exchanger described in FIG. patent document FR 2,562,997 (VICARB ), while ensuring the rigidity of the plates and the mechanical strength of the assembly.
  • the solution proposed by the invention is a heat exchanger comprising a closed chamber inside which are arranged ribbed welded plates defining between them interpenetrating independent circuits in which are intended to circulate fluids; the lateral walls delimiting said enclosure being fixed on vertical spars, the latter being inserted into said brackets.
  • the heat exchanger which is the subject of the invention is remarkable in that the plates comprise in each corner an edge fitting into slots made on angles of vertical angles,
  • corner angles adapted to receive the edges of the plates improves the assembly and maintenance of said plates together. Indeed, the establishment of the plates in the corner angle lights, which are independent of the side members, is simpler than welding said plates directly on said side members. In addition, there are fewer mounting constraints since in the prior art, the longitudinal members must receive not only the plates, but also the side walls forming the enclosure. It is now the corner angles, and no longer the spars, which ensure the separation of fluids between the two circuits. In addition, the thermal and mechanical stresses are now applied to the corner angle lights that can absorb large expansions and pressures, without compromising the tightness of the assembly. Another advantage resulting from the invention is that corner angles now ensure the sheathing and the protection of the side members, which facilitates the design and improves the rigidity and mechanical strength of the exchanger.
  • Another aspect of the invention relates to plates for use in the exchanger according to the characteristics described above.
  • the heat exchanger which is the subject of the invention is of the type comprising a closed enclosure inside which are arranged rib-shaped plates defining between them interpenetrating independent circuits in which fluids are intended to circulate, the lateral walls delimiting said enclosure being attached to vertical spars.
  • This type of exchanger is of the type known to those skilled in the art.
  • the exchanger has the general shape of a parallelepiped whose dimensions depend essentially on the number of stacked plates and the dimensions of the latter.
  • this exchanger comprises one (or more) module (s) 1 of juxtaposed plates 40 of substantially parallelepipedal shape, incrissa (s) on four vertical spars 10 arranged at four corners.
  • the number of modules 1 used is dependent on the flow rate of the fluids to be treated.
  • the longitudinal members 10se are in the form of metal columns, hollow or solid, of substantially rectangular section whose dimensions are variable depending on the operating pressure, for example about 10 cm x 10 cm. Their length corresponds substantially to the height of the module (s) 1.

  • a first fluid will flow through the module 1, between the chamber 202 and the chamber 222 and the second fluid will flow through the module 1, between the chamber 212 and the chamber 232.
  • other directions of circulation suitable for the Those skilled in the art can be envisaged according to the fluids to be treated.
  • each of the walls 20, 21, 22, 23, is provided with an orifice, respectively 201, 211, 221, 231, intended for the passage of a pipe connecting the inlet and the outlet of each; fluids circulating in the exchanger.
  • one wall it is possible for one wall to be provided both with the inlet and the outlet of a first fluid and another wall to be provided with the inlet and the outlet of the second fluid, the other walls having no orifice.
  • the enclosure of the exchanger is provided with an upper cover 30 and a lower bottom 31 sealingly cooperating with the side walls 20, 21, 22, 23 to close said enclosure.
  • the lid 30 is equipped with orifices 300 for purging air and the bottom 31 is equipped with orifices 310 for purging the fluids.
  • the orifices 300 of the cover 30 are positioned vis-à-vis the side chambers 202, 212, 222, 232 so that air can be properly expelled from the latter during filling of the exchanger.
  • the openings 301 of the bottom 31 are also positioned opposite the lateral chambers 202, 212, 222, 232 so that the fluids can flow completely out of these during the purge of the exchanger.
  • the module 1 is made by means of ribbed plates 40 mounted by superposing and alternating, in the manner of a millefeuille.
  • each plate 40 has ribs 400 configured so as to form, during the stacking of the plates, independent and interpenetrating conduits, in which the hot and cold fluids circulate.
