- Such chemical reactors with two fluid circuits with utility are usually called exchanger-reactors.
- the present invention concerns both the production of heat exchanger modules with a sole thermal exchange function and integrating two fluid circuits as well as the production of exchangers-reactors. Also, by “heat exchanger module with at least two fluid circuits”, it is necessary to understand in the context of the invention, both a heat exchanger module with a function only of thermal exchanges and an exchanger -reactor.
- the main use of an exchanger module between two fluids according to the invention is its use with water as one of the two fluids. H can advantageously be an exchange between liquid water and liquid water.
- the main application targeted by an exchanger module according to the invention is the exchange of heat between liquid water of a primary circuit, and a secondary circuit of a pressurized water nuclear reactor (PWR) of small or medium power type or SMR in English (acronym for “Small Modular Reactor”), with heat-generating vocation.
- PWR pressurized water nuclear reactor
- heat-producing we mean here and in the context of the invention, a nuclear reactor whose power is mainly dedicated to the supply of heat.
- the power of a heat-producing reactor can be 100% to provide heat. A small part of its power can still be used to provide electricity.
- a heat exchanger module according to the invention can also be implemented in any other application requiring an exchange between two fluids, such as a liquid and a gas, preferably when it is necessary to have a compact exchanger. and high thermal power.
- primary fluid we mean in the context of the invention, the usual meaning in thermal, namely the hot fluid which transfers its heat to the secondary fluid which is the cold fluid.
- secondary fluid in the context of the invention, the usual meaning in thermal, namely the cold fluid to which the heat of the primary fluid is transferred.
- the primary fluid is the liquid water of the primary circuit of a PWR reactor
- the secondary fluid is the liquid water of the secondary circuit of said PWR reactor
- Known tube exchangers are for example tube and shell exchangers, in which a bundle of straight or curved tubes in the shape of a U or in the shape of a helix is fixed on pierced plates and arranged inside an enclosure waterproof called grille.
- these tube and shell exchangers one of the fluids circulates inside the tubes while the other fluid circulates inside the shell.
- These tube and shell exchangers have a large volume and are therefore of low compactness.
- Existing so-called plate heat exchangers have significant advantages over existing so-called tube heat exchangers, in particular their thermal performance and their compactness thanks to a ratio of the surface area to the volume of heat exchange favorably pupil.
- Compact plate exchangers are used in many industrial fields. In this field of compact plate exchangers, numerous elementary shapes defining heat exchange patterns have been developed.

- the exchange reason may be different between one of the two fluid circuits of the exchanger and the other.
- the assembly between metal plates is usually done by brazing, or by diffusion welding.
- Corrugated or corrugated plate exchangers are also known.
- the undulations are created by stamping a plate separating the two fluid circuits.
- the exchange pattern is identical for each of the two fluid circuits.
- the flow of fluids generated by this type of exchange pattern is three-dimensional and, therefore, very efficient.
- the assembly between plates is done either by bolted connection or by their peripheral welding (conventional welding, or by diffusion welding).
- plate exchangers with machined grooves are known, the machining being mechanical or carried out electrochemically.
- the channels defined by the machining are of millimeter section and are most often continuous and according to a regular zigzag profile.
- the plates are assembled by diffusion welding, in particular by hot isostatic compression (CIC) allowing welding on all contact points between two adjacent plates. This type of machined groove plate exchanger is therefore intrinsically very resistant to pressure.
- the heat exchangers between the primary and secondary circuits of a heat-producing PWR reactor are arranged on the periphery of the reactor vessel, these components being immersed in a basin of water as the secondary circuit fluid.
- the circulation of water in the primary and secondary circuits is carried out by natural convection, without a pump.
- the circulation of the primary fluid is obtained by thermosyphon and that of the secondary fluid is obtained by creating a thermocline within the water basin.
- the inventors of the present application had to design the exchangers between primary and secondary circuits according to this architecture.
- plate exchangers assembled by hot isostatic compression presented various advantages as exchangers between primary and secondary circuits of the aforementioned reactor, in particular due to the fact that compared to tube and shell exchangers, they are often more compact and less sensitive to vibrations.
- the calculations carried out indicate that the pressure loss obtained in the secondary circuit is 2455 Pa, including 1055 Pa in the zone of grooved exchange channels and 1400 Pa in the inlet and outlet precollectors.

- the exchanger module M is described as an exchanger module between liquid water as a primary circuit fluid (Fl) and also liquid water as a secondary circuit fluid (F2) of an SMR type PWR nuclear reactor.
- FIG 1 there is therefore shown a heat exchanger module M according to the invention with two fluid circuits, which is implemented by way of example for an exchange between liquid water (Fl), in as primary fluid and liquid water (F2), as secondary fluid in which the module M can be immersed.
- Fl liquid water
- F2 liquid water
- the module M consists of a stack of metal plates 1 assembled together first in layers by diffusion welding preferably using a CIC technique then by laser welding between them or by insertion of combs in the stack then by compression uniaxial hot, as detailed below.
- Module M can also be produced by additive manufacturing. As visible in this figure 1, this module M which extends along a central axis (X), integrates two collectors 11, 12 respectively for inlet and outlet of the liquid water of the primary fluid (Fl), one being arranged on top of the module along the X axis and the other also being arranged along the X axis of the module but on the bottom. As detailed below, each of the collectors 11, 12 opens onto a side base of the stack of plates 1 onto which the channels of the fluid circuit Fl open but not those of the secondary fluid circuit F2.
- the module M also includes two outlet collectors 22 for the fluid F2, arranged on either side of the inlet collector 11 for the fluid Fl at the top of the module.
- the module M does not include fluid inlet collectors F2 as such, the latter entering directly into the secondary circuit inlet pre-collector from the bottom of the module, as detailed below.
- the module M according to the exchanger comprises a plurality of plates 1 stacked together, one main face 10 of which delimits the circulation of the fluid Fl and the other main face 20 of which, opposite the main face 10, delimits the circulation of the fluid F2, the arrows symbolizing the circulation of each of the fluids in each plate concerned.
- Figure 2 shows the main face 10 of a plate 1, dedicated to the circulation of FL
- the main face 10 comprises two supply and distribution zones ZH each forming a fluid pre-collector, arranged on either side of a heat exchange zone ZE.
- the channels 13 of a pre-collector ZH are delimited by solid cylindrical pads 14 distributed over the plate surface.
- the solid cylindrical pads 14 are uniformly distributed staggered on the surface of the main face 10 at the pre-collector level. More precisely, this staggered distribution is made according to an identical triangular pattern over the entire surface of the main face 10 at the level of the pre-collector ZH. A distribution in a triangular pattern allows better filling of the volume of the pre-collector by the pads 14 and is preferred to ensure the pressure resistance of the exchanger module.
- the channels 13 delimited by the solid cylindrical pads 14 open onto the channels 15 of the heat exchange zone ZE which is continuous with the pre-collector.
- the channels 15 of the exchange zone are each delimited by a groove 15 separated from each other by a rib 16 and extend along the longitudinal axis (X). Preferably, as shown, they are straight, parallel to each other and extend parallel to the longitudinal axis (X) of module 1.
- two adjacent plates 1 with cylindrical studs 14 whose height represents part of the height of a channel 13, are intended to be assembled together with their main faces 10 facing one of the the other to form a sheet 3, the total height of the fluid circulation channel being that cumulative of the pads 14 of the two plates 1 in continuity with one another.
- the arrangement of the pads 14 makes it possible to guarantee the pressure resistance of the plates 1.
- the pads 14 make it possible to guarantee a homogeneous distribution of the primary fluid Fl, i.e. liquid water, independently of the geometry of the channels 15 of their heat exchange zone ZE while presenting low thermal inertia and minimizing the addition of pressure losses.
- the studs 14 are sized to guarantee pressure resistance.
- the liquid water Fl is supplied from the tubular inlet collector 11 to be distributed from the inlet 100 of the channels 13 delimited by the pads 14.
- the liquid water Fl circulates in the channels 13 around the pads 14 of the inlet pre-collector, to reach the channels 15 of the heat exchange zone ZE then circulates around the pads 14 of the pre-collector outlet to be evacuated through the outlet 101 of the channels 13 then recovered by the tubular outlet collector 12.
- Figure 3 shows the main face 20 of a plate 1, dedicated to the circulation of F2.
- the main face 20 is opposite the main face 10 of a plate 1.
- the main face 20 comprises two supply and distribution zones ZH each forming a fluid pre-collector, arranged on either side of a heat exchange zone ZE.
- This main face 20 is delimited by two lateral edges 24, 25 in excess of the flat surface 23 and by two discontinuous longitudinal edges 27, 28, that is to say not continuous between the two side edges 24, 25, and which have the same extra thickness as that of the side edges 24, 25.
- the single channel 23 of a pre-collector Zu is delimited by the flat central surface 23 of the plate, an extra-thickness lateral edge 24 or 25 and the two longitudinal edges 27, 28.
- the single channel 23 of the exchange zone ZE is, for its part, delimited by the flat central surface 23 and the two discontinuous longitudinal edges 27, 28.
- the distance between the lateral edge 24 or 25 and one of the discontinuous longitudinal edges 27 or 28 in excess defines an inlet opening 200 or outlet 201 of the fluid F2.
- the liquid water F2 is supplied from the inlet openings 200 which constitute a sort of inlet collector, then into the 'single channel 23 of flat surface.
- the fluid F2 is then directed and guided by the longitudinal edges 27, 28 from the inlet pre-collector, to reach the single channel 23 of flat surface of the heat exchange zone ZE then is directed and guided by the lateral edge 25 of the outlet pre-collector to be evacuated through the outlet openings 201 then to be recovered by the two outlet collectors 22.
- thermo-hydraulic dimensioning of an exchanger module 1 according to the invention by computational fluid mechanics (CFM) calculations (in English "Computational Fluid Dynamics” acronym CFD).
- Table 2 below explains the geometries of exchange channels on the overall dimensions of an exchanger module M meeting the desired operating conditions for application to an SMR type PWR nuclear reactor, as indicated in Table 1 mentioned in the preamble. [Table 2]
- an exchanger module M is intended to be immersed in a basin of water which constitutes part of the secondary fluid circuit.
- the only pressure acting on the walls of the stack of the secondary fluid circuit corresponds to the isostatic pressure and the pressure losses.
- an exchanger module M receives a secondary fluid with admission speeds, that is to say at the inlet openings 200, which are extremely low. This also validates the deletion of any pad in the precollector.
- layers 3 each consisting of two plates 1 mirrored, that is to say in contact by their pads 14 of their main faces 10, then assembled by CIC.
- the height of the inlet 100 and outlet 101 openings of the primary fluid Fl as well as that of the channels 13, 15 within the inlet and outlet pre-collectors and the exchange zone is determined by the height of the pads 14 and ribs (isthmus) 16.
- the layers 3 are stacked on top of each other with two end plates 5 at the ends of the stack 4 defining the exchanger module M.
- FIGS 10 and 11 illustrate the circulation of the primary fluids Fl and secondary F2 within the assembled stack of layers and end plates 5 of an exchanger module M according to the invention, without its collectors.
- the heights of the discontinuous lateral and longitudinal edges of the main faces 20 of the plates 1 which delimit the circulation of the second fluid F2 can be adapted depending on the application according to the usual sizing rules, mechanical resistance to pressure, pressure losses and of fluid flow distribution.
- the geometries of the pads and the periodicity of the pitch of the rectangular, square or triangular pattern of their distribution, are to be determined depending on the application according to the usual sizing rules, mechanical resistance to pressure, pressure losses and distribution of fluid flow in the channels. If in all the examples illustrated, all the main faces 10 of the plates 1 are made with pre-collectors with pads 14, we can consider making only those of a single fluid circuit, the other being able to include classic pre-collectors.
- the channels of the heat exchange zone (ZE) are straight channels
- the pre-collector according to the invention is independent of this geometry and we can therefore consider other geometries for the exchange channels (ZE), for example curved, zig-zag, double zig-zag channels, etc.
- the depth of the exchange channels determines the height of the pads of the precollector according to the invention.
- the inlet and outlet collectors 11, 12 respectively are tubular in shape and arranged along the longitudinal axis of the module.
- Other arrangements of collecting tubes can also be considered.
- inlet collectors as such are not provided for the secondary fluid, these being produced by the inlet openings 200 of the inlet precollector ZH, we can provide d add more, like the outlet collectors 22.
- the collectors of the two circuits are likely to be sized under pressure (pressure difference between two circuits) or not.
