Definitions
- the present invention relates to a method for manufacturing a heat exchanger of the brazed plate type comprising at least one zone to be supported, as well as to a heat exchanger manufactured by such a method.
- the present invention finds particular application in the field of gas separation by cryogenics, in particular air separation by cryogenics (known by the acronym "ASU" for air separation unit) used for the production of gaseous oxygen under pressure.
- ASU air separation by cryogenics
- the present invention can be applied to the manufacture of a heat exchanger which vaporizes a liquid flow, for example liquid oxygen, nitrogen and / or argon by heat exchange with a gas flow, for example air or nitrogen.
- the present invention can also be applied to a heat exchanger which vaporizes at least one flow of liquid-gas mixture, in particular a flow of mixture with several constituents, for example a mixture of hydrocarbons, by heat exchange with at least another fluid, for example natural gas.
- the technology commonly used for heat exchangers is that of brazed plate exchangers, which make it possible to obtain very compact members offering a large exchange surface.
- These exchangers consist of a set of parallel plates between which are inserted heat exchange structures, in particular corrugated or wave structures, thus constituting a stack of flat passages for different fluids to be put in heat exchange relationship.
- the heat exchange structures of brazed plate heat exchangers not only have the function of increasing the heat exchange surface of the exchanger but also act as spacers between the plates.
- a compression device is used to press the stack of plates, the intermediate elements and the other constituent elements of the exchanger against each other. These elements are then bonded together by brazing in a vacuum oven at temperatures between 550 and 650 ° C, with the application of a compressive force typically ranging from 20,000 to 40,000 N / m 2 .
- a compressive force typically ranging from 20,000 to 40,000 N / m 2 .
- the intermediate elements ensure the rigidity of the exchanger passages and their resistance to compression, avoiding the deformation of the plates by creep.
- the passages have all or part of the zones of reduced resistance at the level of which the plates are subject to deformation during the brazing step. This results in a deterioration of the mechanical strength and the sealing of the exchanger passages following its brazing.
- Document EP-A-2271456 teaches a method of manufacturing a heat exchanger in which a set of shims is introduced into the passages of the exchanger in order to ensure rigidity during brazing.
- This assembly is made up of several wedges of specific geometry secured to each other and the removal of which takes place by imposing a rotational movement on each wedge.
- document DE-B-1 190910 discloses the introduction of rigid shims in the passages of an exchanger before brazing, the shims being removed after brazing by traction using dedicated tools.

- FIG. 2 is a partial view of the exchanger of [Fig. 1]
- FIG. 3 is a view in longitudinal section of a passage of the exchanger of [Fig. 1]
- FIG. 4 is a cross-sectional view of a stack of passages comprising a support member according to an embodiment of the invention
- FIG. 5 is a cross-sectional view of a stack of passages comprising a support member according to another embodiment of the invention.
- FIG. 6 is a cross-sectional view of a support member according to an embodiment of the invention.
- FIG. 1 represents a heat exchanger 1 of the brazed plate type comprises a stack of plates 2 which extend in two dimensions, length and width, respectively in the longitudinal direction z and the lateral direction x.
- the plates 2 are arranged parallel one above the other with spacing and thus form several sets of passages 3 for a fluid F1, and at least one other fluid F2, F3 to be put in indirect heat exchange relationship via the plates 2.
- the lateral direction x is orthogonal to the longitudinal direction z and parallel to the plates 2.
- each passage has a parallelepipedal and flat shape.
- the passages extend in length along the longitudinal direction z and in width along the lateral direction x.
- the difference between two successive plates 2, corresponding to the height of the passage, measured along the stacking direction y of the plates 2, is small compared to the length and the width of each successive plate.
- the passages 3 are bordered by closing bars 6 which do not completely close the passages but leave free openings for the entry or exit of the corresponding fluids.
- the exchanger 1 comprises collectors of semi-tubular shape 7, 9 provided with openings 10 for the introduction of the fluids into the exchanger 1 and the evacuation of the fluids from the exchanger 1. These collectors have narrower openings than the passages. Distribution zones arranged downstream of the inlet manifolds and upstream of the outlet manifolds serve to uniformly channel the fluids to or from the entire width of the passages.
- the exchanger 1 is of the type with brazed plates and fins.
- At least part of the passages 3 includes intermediate elements 8 with fins which advantageously extend along the width and the length of the passages of the exchanger, parallel to the plates 2.
- the intermediate elements 8 comprise heat exchange waves in the form of corrugated sheets.
- the wave legs which connect the successive vertices and bases of the wave are called "fins”.
- the intermediate elements 8 can also take other particular forms defined according to the desired fluid flow characteristics. More generally, the term "fins" covers blades or other secondary heat exchange surfaces, which extend from the primary heat exchange surfaces, that is to say the plates of the exchanger, in the exchanger passages.
- intermediate element does not cover any closure bars 6 which can be arranged to at least partially close the peripheral edges 4 of the passage 3.
- intermediate element preferably a fin heat exchange structure, for example a heat exchange wave, arranged between two plates 2.
- At least one passage 3 of the exchanger comprises at least one zone to be supported 12 (not visible in [Fig. 1]).
- This zone to be supported 12 is preferably a zone devoid of any intermediate element, that is to say a volume left free between two adjacent plates 2
- the area to be supported 12 can also be an area provided with intermediate elements but whose density of fins is lower than another area of the same passage 3, or whose density of fins is lower than another area of another adjacent passage 3.
- the passage 3 may comprise a single support area 12 or else several support areas 12 arranged at intervals along the lateral direction x or the longitudinal direction z, for example support areas 12 separated by one or more grab bars extending in the height of passage 3
- FIG. 2 represents passages 3 delimited by peripheral edges 4 which are preferably two by two parallel in the lateral direction x and the longitudinal direction z. The edges located one opposite the other are said to be opposite.
- the zone to be supported 12 opens towards the outside of the passage 3 through at least one opening 5 arranged at a peripheral edge 4.
- at least one support member 1 1 is arranged in the area to be supported 12. After brazing, the support member 1 1 is removed through the opening 5 by applying at least one tensile force to it (arrow F). This force is exerted so as to cause a deformation and a movement in translation of the support member 1 1 towards the outside of the passage 3.
- the support member 1 1 thus ensures the mechanical rigidity of the area to be supported 12 during assembly by brazing the exchanger, and the removal of the support member 1 1 can be carried out in a simple and rapid manner , without the need to impose a complex movement on it.
- the fact of using a deformable support member 1 1 facilitates its removal and reduces the risk of damaging or deforming the passage 3 in which it was inserted.
- the support member 1 1 can be arranged in the area to be supported 12 during or after the step of stacking the plates 2.
- the support member 1 1 is arranged in the area to be supported 12 during the step of stacking the plates 2.
- the support member 1 1 is placed before one of the two plates is stacked the other.
- said at least one force F can be exerted continuously or in several times on the support member 11 with a variable or constant intensity.
- the support member is, at least in part, plastically deformable.
- the support member is configured to undergo, in whole or in part, plastic deformation, that is to say irreversible. This further facilitates the removal of the support member since it is not necessary to continuously apply the force F.
- the movement in translation of the member 1 1 begins after or during the deformation of the support member 1 1.
- the traction force is advantageously directed in a direction substantially parallel to the plates 2 and perpendicular to the direction of extension of the peripheral edge 4 at which the opening 5 is arranged.
- the opening 5 is located on a longitudinal edge parallel to the longitudinal direction z and the force F is directed in the lateral direction x.
- the support member 1 1 undergoes, under the effect of the force F, a deformation simultaneously in the direction in which the force is exerted, that is to say the lateral direction x in the example of [Fig. 2] and in the stacking direction y which is orthogonal to the plates 2.
- the support member 1 1 undergoes an increase in its initial dimension Di, Di being measured in a second direction which is parallel to the plates 2 and perpendicular to the peripheral edge 4 comprising the opening 5., in particular along one or the other of the lateral x or longitudinal z directions depending on the positioning of the opening 5 and the direction of the tensile force, and a decrease in its initial height hi, hi being measured in a first direction which is parallel to the stacking direction y.
- the height before deformation of the support member 1 1 is such that the member 1 1 extend in almost all, or even all, of the height of the passage 3 in the stacking direction y, so that there is no or almost no play between the member 1 1 and the adjacent plates 2.
- This provides effective support during brazing of the exchanger.
- the reduction in the height of the member 1 1 under the effect of the traction force allows the translational movement of the member 1 1 towards the outside of the passage 3.
- the support member 1 1 is arranged in the area to be supported 12 so that a portion of the member protrudes from the opening 5 towards the outside of the passage 3.
- the portion of the member which extends beyond the closing bar 6 of the edge 4 considered forms a gripping portion, manual or mechanical, which facilitates the withdrawal of the support member 11.
- FIG. 2 shows an embodiment in which an opening 5 is arranged on a peripheral edge 4 parallel to the longitudinal direction z.
- FIG. 3 shows an embodiment in which the area to be supported 12 is through and opens out towards the outside of the passage 3 by two openings 5 arranged on opposite peripheral edges 4.
- the opposite openings 5 can be arranged on a pair of longitudinal peripheral edges, as illustrated in [Fig. 3], or on a pair of lateral peripheral edges which extend in the lateral direction x.
- passages 3 of the exchanger 1 may have at least one area to be supported 12, these passages possibly having different configurations, in particular a different number of openings and openings arranged on different edges.
- the plates 2 are preferably coated with a brazing agent, or brazing, having a predetermined melting temperature.
- the support member 1 1 is formed in whole or in part from a first material having a melting temperature above said predetermined temperature.
- the support member is not brazed with the plates 2 of the passage 3 and can be removed easily.
- FIG. 4 illustrates an embodiment in which the support member 1 1 comprises an internal part 1 1 a formed of a second material and two external elements 1 1 b formed of the first material, each external element 1 1 b being arranged between the internal part 1 1 a and an adjacent plate 2, the second material having a melting temperature lower than the melting temperature of the first material.
- the internal part 1 1 a constitutes the deformable part of the support member 1 1 and the two external elements 1 1 b play the role of insulating parts preventing the brazing of the part 1 1 a to the adjacent plates 2.
- the external elements 11 b can be formed from an alloy of iron, in particular stainless steel.
- the internal part can be made of aluminum or an aluminum alloy.
- the external elements 1 1 b take the form of flat parts, for example sheets or strips. This allows to have a contact area almost continuous, even continuous, with the adjacent plates 2, and thus further improve the mechanical resistance of the area to be supported 12.
- the method according to the invention is preferably carried out according to two sub-stages: withdrawal of the internal part 1 1 a by means of the traction force with deformation and movement in translation of the internal part 1 1 a towards the outside of passage 3, removal of the two external elements 1 1 b without deformation of said elements 1 1 b.
- FIG. 5 shows an alternative embodiment in which the support member 1 1 is a part formed only of the first material.
- an iron alloy such as stainless steel, can be used as the first material which cannot be soldered with the plates 2.
- the support member 1 1 or its internal part 1 1 a takes the form of an intermediate element of the fin type.
- the member 1 1 thus comprises several fins or struts which extend in the passage 3 so as to form secondary exchange surfaces and to define a plurality of channels 13 for the flow of a fluid.
- the method according to the invention is thus easily implemented on an industrial level, with a low investment cost since conventional wave mats can be used as a support member.
- this type of element offers a higher density of areas of contact with the adjacent plates than with the support parts of the prior art.
- FIG. 6 shows an advantageous embodiment in which the support member 1 1 comprises a corrugated product 1 1, 1 1 a comprising a succession of wave legs 123 connected alternately by wave vertices 121 and bases of wave 122.
- the corrugated product is arranged in the zone to be supported 12 so that the wave legs 123 follow one another in a direction parallel to the plates 2 and perpendicular to the peripheral edge 4 comprising the opening 5, considered in the plane (y, z) on [Fig. 4]
- the support member 1 1 thus easily deforms by unfolding in the direction parallel to the plates 2 and perpendicular to the peripheral edge 4.
- FIG. 6 is a cross-sectional view of a support member 1 1, 1 1 a in the form of a straight wave with wave legs 123 of planar surface.
- the support member 1 1 can also be a corrugated product chosen from waves with partial offset, waves with waves or herringbone, perforated or not.
- the support member 1 1 has a predetermined density, defined as the number of wave legs or fins per unit of length, measured along the direction of undulation, for example the lateral direction x in the configuration of [Fig. 2] to [Fig. 6].
- said density is at least 6 legs per 2.54 cm, and preferably less than 26 legs per 2.54 cm.
- the support member 1 1 has a number of legs per 2.54 centimeters identical or almost identical to the number of legs per 2.54 centimeters of the intermediate elements arranged in the same passage 3 as the zone to be supported 12 or in the passages adjacent to the passage 3 comprising the zone to be supported.
- the area to be supported 12 has a second length L2 measured in the longitudinal direction z corresponding to at least 1%, preferably at least 5%, of preferably still at least 10% of the first length L1.
- the method according to the invention is particularly advantageous when the exchanger to be manufactured has at least one area to be supported 12 whose extent is relatively large compared to the dimensions of the passages 3 of the exchanger.
- the length of the area to be supported 12 may represent more than half the length of the passage 3, preferably more than 80%, and may even extend over almost the entire length of the passage 3, typically having a length L2 representing 98% or more of the first length L1, or even over the whole, L2 then representing 100% of L1.
- the passage 3 is then empty or almost empty, that is to say free of intermediate element. It being specified that in the context of the invention, the length of the passage 3 is measured between two opposite peripheral edges 4, which corresponds to the distance between two opposite closure bars 6 when the passage 3 is closed by such bars.
- the dimensional ratios and characteristics mentioned below are of course applicable to the widths of the passage 3 and of the zone to be supported 12, measured in the lateral direction x, in the case where the zone to be supported 12 opens out to the outside of the passage 3 by at least one opening 5 arranged on a peripheral edge 4 extending parallel to the lateral direction 4.
