Definitions
- the invention relates to a heat exchanger of modular structure which can be used in particular for heat exchanges between gases.
- said superimposed lamellae or partitions formed separate channels in which the fluids could flow, for example in rows of alternate channels participating in the exchange, the fluids considered then circulating in parallel currents (in co-currents or against the current).
- some of the lamellae or partitions in particular one of the sets of lamellae or partitions parallel to each other, could also have recesses, creating communications between the channels of the same row allowing one of the fluids to circulate in a direction generally perpendicular to the slats or partitions thus perforated, therefore in a direction generally perpendicular to that of the channels traversed by the other fluid.
- the exchanger could operate in cross currents.
- a particular embodiment described consisted of a three-block exchanger, comprising a central block with parallel currents (for example against the current) corresponding to a structure of the first type above and two terminal blocks corresponding to a structure of the second type above and used for the supply and evacuation of fluids.
- the heat exchangers thus formed could be used in particular for the recovery of heat by air introduced (and discharged) laterally through the terminal blocks in networks of communicating channels, on fumes which, for their part, passed through the blocks terminals by separate rows of channels.
- Another embodiment could consist of a single block corresponding to a structure of the second type above, such a structure being intended to operate in cross currents.
- the invention provides a device for the heat exchange between a relatively hot fluid and a relatively cold fluid, which comprises an exchange zone and means for supplying and discharging each of said fluids, said exchange zone comprising at least one block formed by juxtaposition of a plurality of plates parallel to each other, each plate being provided on at least one of its faces with spacing elements consisting of continuous or crenellated spacers, parallel between them on the same plate and from one plate to another, these plates being formed and arranged in such a way that, for any two adjacent plates, at least one of the opposite faces is.
- spacers at least part of said spacers being, over at least part of their length, in contact with the face of the adjacent plate opposite, or with at least part of the spacers possibly present on said face to face, over at least part of their length; the plates, thus juxtaposed so as to define circulation spaces for said fluids, being further constituted and arranged in such a way that, for one circulation space out of two, the spacers carried by at least one of the facing faces screws of the two adjacent plates delimiting said space, are crenellated spacers.
- crenellated spacers may also be called “indented” (the terms “niche” and “indented” will be used interchangeably).
- Continuous spacers can also be called “full”.
- the plates whose juxtaposition constitutes the exchange zone of the devices of the invention are rec tangular and the spacers they carry - (whether crenellated or continuous) are parallel to the homologous edges of all of said plates.
- the plates 1, the juxtaposition of which constitutes said exchange zone (except possibly the extreme plates), preferably rectangular, have on each of their faces, indented spacers (or crenellated) 2, these spacers, parallel to each other being advantageously parallel to the edges of said plates 1 and equidistant over the width of the plates 1.
- the indentations (or slots) 3 may have a depth equal to the thickness of the spacers 2 or a lower depth. The latter possibility is illustrated in Figure 11.
- the notches 3 may be located in alignment perpendicular to the direction of said spacers 2 as shown in Figures 1 and 1A.
- the spacers 2 are opposite one another and their notches 3 correspond respectively.
- Such a juxtaposition of plates 1 forms an exchange zone 5, as shown in the FIG. 1A, in which the presence of the notches 3 and the projecting parts 4 makes it possible to provide, between any two adjacent plates 1, a circulation network for a fluid, each network being able to be traversed in a direction parallel or in a direction perpendicular to the spacers 2.
- the various adjacent networks are separated, by construction, by the plates 1 themselves, so that there is, between the fluids flowing in adjacent networks, no possible passage, therefore no risk of leakage.
- the structure of the exchange zone 5 offers a large number of circulation possibilities for the fluids traversing the various networks.
- the two fluids can circulate in parallel currents (in co-currents or against the current) parallel to the direction of the spacers 2. They can also circulate in parallel currents (in co-currents or against the current) in a direction perpendicular to that of the spacers 2, through the notches 3.
- the main interest of the structure described above lies in the fact that the two fluids can circulate there in cross currents, one of the fluids circulating parallel to the spacers 2, in one network out of two, the other fluid circulating, -in the other networks, perpendicular to the spacers 2, through the passages created by the notches 3.
- the notches 8 of each of the spacers 7 on the same face of a plate 6 are no longer located (between them) in alignment perpendicular to the direction of the spacers 7, but are offset on two neighboring spacers.
- the circulation space has a different configuration, such as, in particular when the fluid circulates in a direction generally perpendicular to the spacers 8-its circling is done along sinuous paths, and not relatively directly as was the case for the plates 1 of Figures 1 and 1A, where the notches 3 of the spacers 2 were not offset.
- the offset of the notches 8 can have a certain regularity; as shown in Figures 2 and 2A, the notches 8 are offset for a spacer 7 in two, on the same face of a plate 6. It is also possible to envisage a less regular offset, repeating with a periodicity of more than two spacers, or a completely disordered offset over the entire width of one face of a plate.
- the offset arrangement of the notches 8 only concerns one network out of two in the exchange zone 10, but it could also concern all the traffic networks.
- the notches 8 (and the protruding parts 9) of the spacers 7 of each of the faces of the same plate 6 have staggered arrangements, the "regularity" of the offset can be provided for different on both sides of the same plate 6.
- the plates 11, as shown in Figure 3 only carry spacers 12 on one of their faces, these spacers 12 having notches 13 , located for example in alignment perpendicular to said spacers 12 of the same plate 11.
- the exchange zone once assembled has a geometry similar to that of the exchange zone 5 as shown in Figure 1A and described above.
- they can be circulated each in a network on two, in -currents parallel to each other and parallel to the spacers 12, in currents parallel to each other and perpendicular to the spacers 12, or in cross currents.
- the plates whose juxtaposition constitutes said exchange zone (except possibly the extreme plates) have spacers on each of their faces which are, on a of the faces of each plate, full or continuous spacers, the spacers of the other face of the same plate being indented.
- the plates 15 bear on one of their faces scalloped spacers 16 and on the other face of solid spacers 17.
- a face d 'a plate 15 carrying solid spacers 17 has vis-à-vis a face carrying solid spacers 17 of the adjacent plate 15, the solid spacers 17 of the opposite faces generally being opposite one another .
- the face of a plate 15 carrying indented spacers 16 has opposite one face of the adjacent plate 15 itself carrying indented spacers 16, said spacers 16 generally being opposite one another others, their notches 18 and their projecting parts 19 corresponding respectively (whether these notches 18 and these projecting parts 19 are on the same plate 15 in alignment or that they are offset one relative to the other on any two neighboring spacers) .
- the juxtaposition of the plates 15 forms an exchange zone.
- the solid spacers 17 on one side of a plate 15 coming into contact over their entire length, with the corresponding spacers 17 on the opposite side of the adjacent plate 15 form rows of parallel channels which can be traversed -by one of the fluids involved, parallel to the spacers 17. Furthermore, the coming into contact of the protruding parts 19 of the scalloped spacers 16 with faces facing two adjacent plates 15 makes it possible to form a circulation network for a second fluid.
- the set of networks can be traversed by said second fluid in a direction parallel to the spacers 16 (in this case, the two fluids circulate in parallel currents: in co-currents or against the current) or in a direction perpendicular to the spacers 16 , through the passages created by the notches 18 (in this case the two fluids circulate in crossed currents).
- said exchange zone can be constituted by the alternating juxtaposition of plates carrying spacers - (crenellated or continuous) on both sides and plates without spacers.
- each male lug 20 on one face 23 of a plate 22 being opposite a female lug 21 from the face opposite 24 of the adjacent plate 22, in the juxtaposition of the plates.
- a female positioning lug 21 may consist, for example, of a volume (for example of cylindrical or parallelepiped shape), emerging from a height h, from the face 24 of the plate 22 which carries it, whose end section plane 25 is advantageously parallel to said face 24, and which has a cavity 26 (for example of cylindrical or parallelepiped shape whose axis and / or the walls have a direction perpendicular to said face 24) open on the face of the lug opposite to the plate, that is to say on section 25.
- the depth p, of the cavity 26 is less than the height h, of the female lug, the bottom 27 of said cavity 26 is at a distance I 1 of the face 24 of the plate 22.
- a male positioning lug 20 may consist for its part of a volume emerging from a height h 2 from the face 23 of the plate 22 which carries it, including the plane. of extreme section 28 is advantageously parallel to said face 23 and of which at least one part 29, of height p2, less than or equal to the total height h 2 of said lug, has a suitable shape (for example frustoconical or truncated pyramidal) to be able to s 'Engage in the cavity 26 of the female lug 21 which faces it.
- the dimensions and shape of the male and female lugs 20 and 21, in particular the inclination of the truncated frustoconical or pyramidal surface of the part 29 of the male lug 20, are chosen in such a way that the positioning of the adjacent plates, at a distance determined by the heights of the spacers 31 and 32 presents the least possible play.
- the dimensions of the internal edge of the cavity 26 of the female lug 21 should be identical to the dimensions of the frustoconical or truncated pyramid part 29 of the lug male 20, at its junction with the base 30 - (or with the face 23 of the plate when there is no base).
- the extreme plane 28 of the frustoconical or truncated pyramidal part 29 of the male lug 20 is not in contact with the bottom of the cavity 26 of the female lug 21; and we ap 2 ⁇ p, or h2 + I, ⁇ d.
- the dimensions of the inner edge of the cavity 26 of the female lug 21 are identical to those of the section of the frustoconical or truncated pyramid part 29 of the male pin 20 at the same level, it being further preferred that there is no contact between the extreme plane 25 of the female pin 21 and the extreme plane of the base 30 of the male pin 20 , when there is such a base, or with the face 23 of the plate, when there is no base. So we have p, ⁇ p 2 or h, + I 2 ⁇ d.
- the most advantageous case is that where the contact between the male pins 20 and the female pins 21 is made neither by bringing the extreme plane 25 of the female pins 21 into contact with the base 30 of the male pins 20, nor by placing in contact with the extreme plane 28 of the male pins 20 with the bottom 27 of the cavity 26 of the female pins 21, but by bringing the inner edge of the cavity 26 of the female pins 21 into contact with the frustoconical or truncated pyramid part 29 of the male pins 20, at an intermediate level thereof, where the dimensions coincide.
- this arrangement there is no possible lateral play between the plates. This is the one shown in Figure 5.
- each plate 22 The positioning lugs 20 and 21 described above can be distributed in any manner on the faces of each plate 22, with the condition that each male lug 20 on one face 23 of any plate 22 corresponds to a female lug 21 from the face 24 opposite, from the adjacent plate 22.
- the positioning pins 20 and 21 - can be placed between the spacers or on the spacers themselves.
- the male and female positioning pins considered in the invention may have other shapes than those described above. They will be equivalent to the lugs 20 and 21 when they provide the same function which consists in preventing the displacement of the plates with respect to each other in a plane direction parallel to the plane direction of the plates.
- the juxtaposed plates which constitute the exchange zone of the device of the invention can be held against each other by any usual clamping means, for example by means of end plates connected and tightened together by tie rods passing through the outside of the block constituting the exchange structure.
- tie rods 35 consisting for example of metal rods threaded at their ends, these ends passing through, on either side of the block constituting the exchange structure, flanges of preferably metallic and pierced with openings corresponding to the openings 34 pierced in the plates 22, the tightening of the assembly formed by the flanges and the exchange structure which they enclose can be achieved by means of nuts screwed onto the threaded ends rods constituting the tie rods 35.
- the openings 34 allowing the passage of the tie rods 35 previously described can be the source of leakage of a fluid (for example relatively cold) in the other fluid (for example relatively hot), through the plates 22, said openings can be, according to a particular arrangement of the invention, practiced through parts of the plates specially designed to ensure, during the tightening of the assembly of the plates, the seal between the spaces for circulation of the fluids situated on either side of each plate.
- the openings 34 made in the plates 22 are provided with sleeves 36 of geometry such that their extreme edges come into contact when the assembly of the plates 22 is tightened, thus preventing the passage of fluid through the openings 34 from a circulation space 37 to the neighboring circulation space 37.
- This arrangement repeating itself over the entire extent of the exchange block, the limitation of leaks between all the circulation spaces situated on either side of the plates is thus ensured.
- the openings 34 for the passage of the tie rods 35 can be distributed in any manner on the surface of the plates 22.
- the distribution is preferably relatively regular.
- the openings 34 for the passage of the tie rods 35 can be made through the positioning pins 20 and 21 as described above, the geometry of which must then be such that they ensure both the positioning of the plates 22 relative to each other and the limitation of leaks between the spaces 37 for the circulation of fluids on either side of the plates 22, this limitation of leaks being produced by the contacts between the male and female parts of the positioning pins.
- An exchanger structure according to the invention can be constituted by the juxtaposition of a number of plates as described above.
- each plate can be constituted by assembling in the same plane several elementary plates, the plates to be assembled then being provided, on their respective edges, with suitable securing devices, the assembly being carried out by mutual embedding of said plates. securing devices.
- a number m of elementary plates by their edges perpendicular to the direction of the spacers and / or assemble a number n of elementary plates by their edges parallel to the direction of the spacers, thus forming plates comprising mxn elementary plates, m and n being any integers (at least one of which is at least 2).
- the numbers m and n are not very high.
- the lateral assembly of the plates along their edges perpendicular to the direction of the spacers can be achieved for example by devices such as those shown in Figures 7 and 8 or by equivalent devices.
- the assembly devices are based on the same principle which consists in embedding a projecting part or tongue 38 of the edge of one of the plates to be assembled 39 in the corresponding hollow or groove 40 formed in the edge of the adjacent plate to be joined 41.
- Said protruding part 38 has the same thickness as the plate 39 in FIG. 7 and a lesser thickness in FIG. 8.
- the lateral assembly of the plates along their edges parallel to the direction of the spacers can be carried out for example, as shown in Figures 9 and 9A, by embedding lugs 42 emerging from the edge of a plate 43 in holes 44 practically of the same dimension formed in the edge of the adjacent plate to be assembled, opposite said lugs 42.
- a block is generally used consisting of juxtaposition of plates which can correspond to the different types described above, with the exception of those in which the spacers are continuous in all the spaces located between adjacent plates.
- a particular mode is shown in Figures 11 and 11A.
- the fluid is evacuated generally by the face of the exchange block opposite to the supply face, through openings similar to the openings 45, of a plate similar to the plate 46 (not shown in FIGS. 11 and 11A), said plate also closing off the spaces 48 intended for the circulation of the second fluid.
- the fluid which must circulate in the spaces 48 in a direction generally parallel to the spacers 2 of FIG. 11A, it can be introduced through the openings 49 of the plate 50, these openings giving access to the spaces 48, said plate 50 closing by elsewhere the spaces 47 intended for the circulation of the first fluid.
- the evacuation of said second fluid is carried out by the face of the exchange block opposite to the supply face, through openings 51 of the plate 52, said plate also closing off the spaces 47 intended for the circulation of the first fluid.
- FIG. 10B Another possibility of implementing the exchanger structures according to the invention is shown diagrammatically in FIG. 10B.
- the exchange block includes three zones whose role can be defined in relation to the circulation of the first fluid (introduced laterally), it being understood that the second fluid circulates in the same way in the three zones, namely parallel to the direction of the spacers, either from bottom to top or (as shown in Figure 10B), from top to bottom.
- the lower zone which is for example the supply zone of the first fluid, the latter circulates almost in cross current with the second fluid.
- the two fluids circulate in parallel currents (against the current if the second fluid circulates from top to bottom or in co-currents, if the second fluid circulates from bottom to top) and in the upper zone, which is in the case considered the evacuation zone of the first fluid, it circulates almost in cross current with the second fluid.
- the plate supply (respectively discharge) of the second fluid it suffices, in the plate supply (respectively discharge) of the second fluid, to provide the openings necessary for the introduction (respectively at the outlet) of said fluid only in the lower part - (respectively in the upper part) of the plate considered.
- the dimensioning of the exchanger structures of the invention can be very varied depending on the flow rates and temperatures of the fluids put into exchange relationship.
