Definitions
- the present invention relates to a heat exchanger of the brazed plate and fin type for the vaporization of a refrigerant liquid by heat exchange with a heat transfer fluid, and to a method of assembling such a heat exchanger.
- the heat exchanger can in particular be a vaporizer used in an air separation column by cryogenic distillation to ensure the vaporization of a column bottom liquid, for example liquid oxygen, by heat exchange with a caloric gas, for example air or nitrogen.
- a vaporizer used in an air separation column by cryogenic distillation to ensure the vaporization of a column bottom liquid, for example liquid oxygen, by heat exchange with a caloric gas, for example air or nitrogen.
- the present invention finds particular application in the field of gas separation by cryogenics, in particular the separation of air by cryogenics (known by the acronym "ASU" for air separation unit) exploited for the production of oxygen gas under pressure.
- ASU air separation unit
- the present invention can be applied to a heat exchanger which vaporizes a liquid flow, for example oxygen, nitrogen and / or argon by heat exchange with a gas.
- the heat exchanger is in the tank of a distillation column, it can constitute a vaporizer operating as a thermosiphon for which the exchanger is immersed in a bath of liquid descending the column or a vaporizer operating in vaporization with a film fed directly by the liquid falling from the column and / or by a recirculation pump.
- phase-change exchangers consist of aluminum exchangers with brazed plates and fins, which make it possible to obtain very compact members with a large exchange surface.
- These exchangers consist of plates between which are inserted waves or fins, thus forming a stack of "passages” of vaporization and "passages” of condensation.
- waves such as straight waves, perforated or “serrated” waves.
- the liquid oxygen that is vaporized contains impurities in dissolved form.
- the main impurities are nitrous oxide (N2O), carbon dioxide (CO2), hydrocarbons (C2, C3, ).
- these impurities can be deposited in the vaporization passages (either in solid form or in liquid form). It is important to control industrially the formation of these solid or liquid deposits to avoid any risk of explosion.
- the so-called secondary distribution (distribution of the liquid between channels) typically uses a horizontal generator waveband, possibly partially offset.
- these waves are juxtaposed with a zero or almost zero clearance.
- the step of fixing the waves by soldering adjacent plates can cause the appearance of a game at the junction between two waves.
- a slight displacement of one wave relative to the other can occur during the melting of the solder metal.
- Games between adjacent waves are preferential passages for the liquid, generating a liquid supercharging of the channels located just below the game but most importantly, a liquid underfeed channels at the periphery of the latter.
- Document FR-A-2938904 discloses solutions for maintaining the waves of an exchanger between them.
- these solutions are not entirely satisfactory, in particular because they do not allow a fairly solid connection of the waves between them.
- these solutions can be problematic because of the complexity and cost of the holding parts used and their difficult implementation within the exchanger, incompatible with an industrial manufacturing process.

- the assembly member comprises a perforated or grooved peripheral wall.
- the first and second waves are formed of a first material and the connecting member is formed of a second material, the second material having a melting temperature greater than or equal to the melting temperature of the first material.
- the plates extend parallel to a flow direction x, the channels and the assembly member extend generally in a first direction orthogonal to the direction of flow y.
- the first and second waves each comprise a succession of wave legs connected by wave tops, the assembly member being forcibly engaged between at least portions of two successive wave legs of the first wave of waves; on the one hand, and between at least portions of two successive wave legs of the second wave on the other hand.
- each channel is defined between a plate, two successive wave legs of the first or second wave and a wave-top connecting said two wave-legs.
- the first and second waves are chosen from straight waves, perforated straight waves, partial shift waves, wave waves or herringbone waves.
- the invention relates to a distillation air separation plant, characterized in that it comprises at least one heat exchanger according to one of the preceding claims and in that the installation comprises means for feed for distributing liquid oxygen in the passages of the exchanger as a refrigerant and nitrogen gas as a circulating fluid.
- the invention also relates to a method of assembling a heat exchanger according to the invention, characterized in that it comprises the following steps:
- FIG. 1 is a partial three-dimensional view of an exchanger according to one embodiment of the invention
- FIG. 2 is a diagrammatic sectional view of the exchanger of FIG. 1,
- FIG. 3 schematizes a wave of an exchanger according to one embodiment of the invention
- FIGS. 4A and 4B are diagrammatic views, respectively of two section planes perpendicular to one another, of two waves of an exchanger according to another embodiment of the invention.
- FIG. 5 is a three-dimensional view of one of the waves of Figures 4A and 4B.
- FIG. 1 illustrates an embodiment of a heat exchanger 2 for use in a double column type air distillation plant.
- heat exchange operates between liquid oxygen as a refrigerant and nitrogen gas as a heat sink fluid.
- the exchanger 2 comprises a sealed envelope 40 containing a set of rectangular plates 4, generally formed of aluminum, which extend generally parallel to each other.
- the plates 4 thus define a plurality of passages for the flow of oxygen (passages 17) or the flow of nitrogen (passages 18).
- the passages 17, 18 each contain heat exchange waves 19 formed in this example perforated corrugated aluminum sheets.
- These exchange waves 19 are preferably of the vertical generator type, or so-called "easyway" provision.
- the exchange waves 19 present, in operation, a global direction of waviness (in the z direction in Figure 1) perpendicular to the flow direction (in the x direction in Figure 1) of the fluids in the passages considered.
- the exchange waves 19 are extended respectively by distribution wavebands 24 and conventional waves 20. Above the waves 20, the passages 17 and 18 are respectively closed. by horizontal bars 28 and 21.
- the space above the plates 4 encloses a bath of liquid oxygen 5.
- the liquid oxygen of the bath 5 flows through orifices 29 pierced along the bars 28 ensuring a primary distribution of the liquid oxygen between all the passages 17 for oxygen and the entire width of each passage 17, in the direction of the wavebands 24.
- the wavebands 24 are generally formed of non-perforated corrugated aluminum sheets of the horizontal generatrix type, or so-called "hardway" provision. In this case, the wavebands 24 have, in operation, a global direction of waviness (in the x direction in Figure 1) parallel to the flow direction of the fluids in the passages considered.
- the nitrogen gas reaches the exchanger through a feed box (not shown) and the distribution waves 20, then flows down along the passages 18. In so doing, it gradually yields the heat to the liquid oxygen which is in the adjacent passages 17, so that the oxygen vaporizes and the nitrogen condenses.
- Figure 2 schematizes a passage 17 for the flow of liquid oxygen.
- the passage 17 is formed between two parallel vertical plates (not shown) separated by bars 15, 7 which clog the passages.
- the first and second waves 14, 34 extend between two successive plates (not shown in FIG. 2) so as to define, within the passage 17, a plurality of channels 14, 34.
- the first and second waves 14, 34 comprise two edges 10, 30 adjacent, defining between them a clearance 31 zero or very low, typically a clearance of 0.1 to 5 mm at most.
- the liquid oxygen passes through holes (not shown in Figure 2) placed above the first and second waves 14, 34, at a flow rate defined by the passage section thereof and by the height of the bath liquid that overcomes it.
- the holes thus provide a primary distribution of the liquid oxygen over the entire width of the passage 17, and the liquid oxygen thus pre-distributed flows on the waves 14, 34, which ensures a fine secondary distribution over the entire width 17.
- the liquid oxygen thus approaches a lower wave vertical generatrix 19 by dripping as homogeneously as possible on all the walls of the passage that is assigned to it, that is to say by forming on these walls a film continuous descending.
- the exchanger according to the invention comprises an assembly member
- the assembly member 13 extending on either side of the edges 10, 30 so as to assemble said waves 1, 3 to one another.

- the member 13 may be penetrated into the channels 14, 34 by means of a small tool, such as a flat screwdriver, making it possible to force the assembly member into the bottom of the wave and by exerting manual pressure.
- the connection between the member 13 and the waves 14, 34 is provided by elastic deformation of one and / or the other of these elements.
- the assembly member 13 is locked in position inside the channels 14, 34 by a wedging effect, which causes the immobilization of the first and second waves 1, 3 with respect to the other.
- the blocking force of the assembly member 13 in the first and second waves 1, 3 ensures a fastening of the assembly member 13 with the first and second waves 1, 3 strong only with a simple embedding, and therefore stronger solidarity between the waves 1, 3.
- the waves 1, 3 are thus assembled to one another through the member 13. The risk of occurrence of a game between the waves during the assembly of the exchanger is greatly limited or eliminated.
- connection between the waves 1, 3 can thus be achieved simply and quickly.
- the assembly does not require any additional fixing means and can be easily implemented at the industrial level, with a low investment cost.

- the ratio between the inner dimension of the channel 14 of the first wave 1 and said outer dimension of the connecting member 13 and the ratio between the inner dimension of the channel 34 of the second wave 3 and said outer dimension of the assembly member 13 are preferably between 100 and 70%, more preferably between 95 and 85%. Such values make it possible to achieve an assembly without heavy tools since the effort of engagement can be assured by hand.

Said height corresponding, with reference to Figure 3, the inner dimension of the channel 14 measured in a third direction y orthogonal to the first direction z and the second direction x. It should be noted that the external dimension of the assembly member 13 will advantageously be adapted as a function of the height of the wave.
