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.
- 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 comprises (the references in parentheses apply to this document) a closed enclosure inside which are arranged welded ribbed plates (1, 18, 19) defining between them interpenetrating independent circuits in which are intended 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 plate attachment method (1, 18, 19) described in 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 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 plates (20) described in 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 provide an exchanger which can have a greater exchange surface than that of the exchanger described in patent document FR 2,562,997 (VICARB), while ensuring the rigidity of the plates and the resistance mechanics of the whole. - AT -
- 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. Description of the figures.

- 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 side 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 plates 40 juxtaposed substantially parallelepiped 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.
- side walls 20, 21, 22, 23 are preferably metal panels of a few millimeters to several centimeters in thickness depending on the fluid pressures circulating in the exchanger.
- the fixing of the walls 20, 21, 22, 23 on the longitudinal members 10 is advantageously by means of screws 200, bolts or in any other manner suitable to those skilled in the art.
- the side walls 20, 21, 22, 23 form, in association with the longitudinal members 10 and the module 1, independent lateral chambers, 202, 212, 222, 232 respectively, in which the fluids circulate. .
- 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 skilled person may be considered depending on the fluids to be treated.
- each of the walls 20, 21, 22, 23, is provided with an orifice, respectively 201, 211, 221, 231, for the passage of a pipe of connection of the entrance and exit of each; fluids circulating in the exchanger.
- one wall is 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 to form, during the stacking of the plates, independent and interpenetrating conduits, in which flow the hot and cold fluids.
- the geometry of the ribs 400 is well known to those skilled in the art and will not be detailed in more detail in the present description.
- the plates 40 are generally rectangular or square. Their number depends on the service conditions and their dimensions vary from 20 cm x 20 cm to 2 m x 2 m or more. For large flows and large heat capacities, several modules 1 of plates 40 will be arranged in parallel.
- the plates 40 are made from embossable metals such as: stainless steel, titanium, nickel, Hastellogs®, etc. They are welded alternately so as to alternately form open faces and closed faces.
- the plates 40 comprise in each corner an edge 41, preferably horizontal.
- This horizontal edge 41 may have the shape of a bracket (for example L-shaped or V-shaped) oriented towards the inside of the plate 40 (FIGS. 9a and 9d), have a bevelled shape (FIG. 9b) or have a circular shape facing inwardly of said plate (Figure 9c), or any other form suitable for the skilled person.
- Their width varies, in practice, from a few millimeters to a few centimeters, their thickness being that of the plates 40.
- the ridges 41 can be easily obtained during stamping of the plates 40.
- These edges 41 can be located only at the corners of the corners.
- edges 41 have their edges offset in space, that is to say that the edges are in two different but parallel planes.
- a first edge of edges 41 is in a first plane P1 located below ribs 400 and the second edge, perpendicular to said first edge, is located in a second plane P2 located above said ribs.
- the horizontal edges 41 are intended to be fitted into horizontal lights 600 made on angles of vertical angles 60.
- the vertical members 10 are then inserted into these angles 60.
- the latter are in the form of one-piece metal profiles, for example obtained by folding or stamping, and having a central part whose shape corresponds substantially to the general shape of the ridges 41, c ' that is to say having a shape of square, bevel, circular or other.
- the horizontal lights 600 are formed at the central angular (or beveled or circular) angles 60, said lights being parallel to each other and arranged one above the other.
- each light 600 extends on either side of the central portion of the angles 60. This type of light 600 is particularly intended to receive plates 40 as shown in Figure 1a. In an alternative embodiment shown in FIG. 5c, each light 600 extends only on one side of the central part of the brackets 60, said slots being staggered, that is to say they present alternately on one side or the other of said central portion. This type of light 600 is particularly intended to receive plates 40 as shown in Figure 1b. It may however be noted that the plates 40 shown in FIG. 1b can also be positioned in the brackets 60 shown in FIGS. 5a and 5b.
- edges of the edges 41 being offset in space, they will fit alternately in the lights 600, but only on one side or the other of the central portion of the angles 60. The portion of the lights 600 that will not receive not the edges of the edges 41 will then be closed, for example by welding.
- Each light 600 is in fact intended to receive two edges 41 which are superimposed following the juxtaposition of two plates 40 ( Figure 7).
- the lights 600 have, in principle, a thickness equal to the thickness of two ridges 41 superimposed, or slightly higher, to facilitate the casing.
- the lights 600 are sized to receive exactly the edges 41, a game being preferably provided to facilitate nesting.
- the end of said ridges is at the base of the inner surface of the angles 60.
- solder cords 70 are thus produced in line with the lumens 600. These welds 70 not only seal the plates 40 angles, but also the mechanical connection between said plates and corner angles
- the vertical weld bead inside the corner angles 60 along their angular central portion (or beveled or circular).
- use will preferably be angle corners 60 as shown on the Figures 5b and 5c, that is to say having a longitudinal slot 601 in their central angular (or beveled or circular).
- the vertical weld seam sealing between the fluid circuits will be formed in this longitudinal slot 601, outside of said fluid circuits.
- this solution is particularly advantageous in the case where the fluids are aggressive.
- the welding operations generate projections likely to affect the material of the plates 40 and generate corrosion primers in the exchange zone.
- the solution consisting in making the welds outside the fluid circuits makes it possible to remedy this state of affairs by protecting the plates 40 and preserving the exchange zone.
- the vertical corner angles 60 are intended to receive the vertical longitudinal members 10.
- the brackets 60 therefore have in practice a profile complementary to that of the longitudinal members 10. It may be advantageous to provide the sides of the corner pieces 60 of fins 6000 vertical ( Figures 5a, 5b and 5c) configured to maintain the longitudinal members 10 within said brackets.
- a seal 80 PTFE or graphite, is disposed between the side walls 20, 21, 22, 23 of the enclosure and the portion of the brackets 60 vis-à-vis said walls. In this way, when the side walls 20, 21, 22, 23 are fixed to the longitudinal members 10, the joints 80 are crushed and ensure the sealing of the chambers 20, 21, 22, 23.
- the vertical fins 6000 also define the range joints 80.
- the edges of said plates are preferably provided with one or more horizontal edges 42 additional.
- the edges having a length greater than a value determined by those skilled in the art, for example greater than 1 m may be provided with these additional edges 42 in their middle.
- additional horizontal edges 42 may have the shape of a U oriented towards the inside of the plate 40 (FIG. 9d) or may have a circular shape (semicircle) oriented towards the inside of said plate, or any other suitable form. to the person skilled in the art. They have the same width and the same thickness as the corner edges 41.
- the additional edges 42 are easily obtained during the stamping of the plates 40.
- the additional ridges 42 are intended to fit into horizontal slots 900 made on additional vertical angles 90. Additional longitudinal members 91 are then inserted into these additional angles 90.
- these additional angles 90 are in the form of one-piece metal profiles, having substantially the general shape of additional edges 42, that is to say having a U-shaped, circular or other.
- the lights 900 are parallel to each other, arranged one above the other and have the same thickness as that of the lights 600. In practice, the lights 900 are sized to receive exactly the additional edges 42 , a game being preferentially provided to facilitate nesting.
- the end of said ridges is at the base of the inner surface of the additional angles 90.
- welding beads 901 are made in line with 900 lights to ensure the mechanical connection between the plates 40 and additional angles 90. It is also possible, but not necessary, to produce a vertical weld bead along at least one of the outer edges of each additional angle 90, at the plates 40.
- the additional vertical angles 90 are intended to receive the additional vertical spars 91.
- the additional angles 90 are therefore in practice a profile complementary to that of the longitudinal members 91. It may be advantageous to provide the sides of the angle 90 fins vertical members 9000 (FIG. 6) configured to maintain the longitudinal members 91 inside said brackets.
- the enclosure of the exchanger may be closed by two side walls 20a-20b, 21a-21b, 22a-22b and 23a-23b, respectively each attached to a corner spar 10 and an additional vertical spar 91 by means of screws 200, bolts, or in any other manner suitable to those skilled in the art.
- a seal 80 made of PTFE or graphite, is disposed between the side walls of the enclosure and the portion of the additional angles 90 vis-a-vis said walls.
- the vertical vanes 9000 also define the range of the joints 80.
- the side walls 20a, 20b, 21a, 21b, 22a, 22b, 23a, 23b are metal plates having a thickness ranging from 50 mm to 200 mm depending on the fluid pressure. Without additional ridges 42 and additional angles 90, it would be necessary to provide one-piece side walls connecting each corner angle, said walls having to have a greater thickness to withstand the pressure of the fluids. The technical solution proposed by the invention therefore significantly reduces the thickness of the side walls of the exchanger.
- Additional ridges 42 and additional angles 90 may also be provided on reduced or standard exchangers, for example exchangers composed of plates 40 having a length of about 30 cm, but subjected to significant pressures (of the order from 35 bar to 40 bar). This design will contribute to the rigidity of the assembly by avoiding that the plates are disconnected locally from each other under the effect of pressure.
