Definitions
- the present invention relates to a method of manufacturing a device of the ceramic heat exchanger type. It also relates to devices of the ceramic heat exchanger type.
- heat exchangers means heat exchangers that allow a heat transfer between the ambient air and a fluid passing through the exchanger or between two fluids passing through the exchanger, also the reactor exchangers which, with a heat transfer, make it possible to provoke a reaction. chemical and also heat sinks for electronics.
- the present invention relates to the field of assembled plate devices.
- the invention is particularly applicable to the manufacture of ceramic heat exchangers formed of a face-to-face plate assembly, also called superimposed layers.
- the invention is applicable to the manufacture of heat exchangers / thermal reactors / heat sinks of silicon carbide.
- the use of silicon carbide (SiC) provides, in addition to a broader corrosion resistance than most other ceramic materials, greatly improved exchange conditions thanks to the excellent thermal conductivity of SiC.
- a plate device is composed of several stacked plates.
- One or more plates (s) comprises a fluid circulation circuit (liquid or gas), and a device for the arrival and departure of the fluid.
- the plates are arranged alternately so that a stage is dedicated to the circulation of the fluid or fluids to be treated, the next stage being devoted to the circulation of the coolant (heating or cooling), and so on.
- Proper configuration allows each plate to be fed with the desired fluid.
- Two fields of application of these devices are particularly targeted by this invention, without the scope of the invention being limited to these two areas:
- the present invention aims to overcome the disadvantages of the state of the art.
- the present invention unexpectedly provides for such an application, a simple and inexpensive solution that goes against all the solutions proposed so far. Indeed, this solution does not involve brazing or adding a seal or the supply of a third material or the combined use of temperature and pressure to seal between the plates of fluid circuits and vis-à-vis the outside.
- the applicant has broken with known techniques which, as has been said are complex to implement and expensive, although the latter provide a good seal.
- the applicant has had the idea of sealing a heat exchanger type device by means of a adhesive bonding of the plated parts of the plates forming the device.
- the mechanical connection between the plates is dissociated from the sealing function.
- This mechanical connection can be made by a conventional clamping system, which leaves the possibility if necessary, to disassemble the assembly (disassembly of the exchanger possible).
- the present invention relates to a method of manufacturing a device of the ceramic heat exchanger type with assembled plates.
- the method consists in producing ceramic plates, one of which has a fluid circuit (s), to polish the faces of the plates intended to be applied against one another, to apply the polished faces of the plates against each other and thus achieve the desired sealing assembly.
- the present invention more particularly relates to a method of manufacturing a ceramic heat exchanger type device with assembled plates, characterized in that it comprises the following steps: 1. making at least two ceramic plates, of which at least at least one has a fluid circuit (s),
- the invention also relates to a heat exchanger obtained by the method, a thermal reactor obtained by the method, a heat sink obtained by the method.
- FIG. 1 represents a schematic exploded view of a device of the heat exchanger type according to the invention
- FIG. 2 represents the two plates of FIG. 1, assembled according to the method of the invention, forming a ceramic module
- FIG. 3 represents an additional plate making it possible to produce the heat exchanger
- FIG. 4 represents the heat exchanger produced according to the method of the invention
- FIG. 5 shows the schematic of the plates in an exploded view for the production of a chemical reactor
- FIG. 6 is a diagram of a reactor produced according to the method of the invention
- FIG. 7 represents the schematic exploded view of the plates for the production of a heat sink
- FIG. 8 shows the diagram of a heat sink made according to the method of the invention.
- the two polished faces of two ceramic plates 1, 2 are pressed against each other, as illustrated by FIGS. 1 and 2, to obtain a tight assembly, the plates being thus bonded by adhesion of the smooth surfaces in contact.
- this adhesion is more or less strong and may be chosen by those skilled in the art, according to conditions of use of the device and its applications as a heat exchanger or reactor or heat sink .
- This bonding makes it possible to seal the fluid circulation circuit (s).
- the seal thus obtained does not impose any thermal stress or pressure to be implemented. It also offers the skilled artisan flexibility of manufacture, since it can adapt the degree of polishing as needed. Indeed, according to the desired pressure and sealing levels, a simple mechanical pressure is sufficient to achieve the desired seal.
- the bonding of the two plates can be ensured by adhesion of smooth faces of higher degree. This is a molecular membership. Molecular adhesion is obtained when the surfaces to be bonded are sufficiently smooth, free of particles or contamination, and are sufficiently close together to allow contact, typically at a distance of less than a few nanometers. In this case, the attractive forces between the two surfaces are high enough to provide molecular adhesion.
- the molecular bonding is initially induced by the set of attractive forces (Van der Waals forces) of electronic interaction between atoms or molecules of the two surfaces to be bonded. These attractive forces are all the more important as the distance between the two surfaces is small.
- Bonding by adhesion can be done perfectly at ordinary temperature and pressure, after polishing the faces and depending on the case, after a chemical cleaning of the surfaces to remove any impurity.
- the bonding energy force may, however, vary according to the cleaning carried out before bonding, the possible addition of hydroxides on the surfaces, and the possible implementation of a post-bond heat treatment.
- a green preform is obtained by isostatic pressing, at 1400 bars for example, of submicron silicon carbide powder to which have been added the appropriate additives to obtain a ceramic.
- Flat samples are machined in this blank to obtain at least two ceramic plates 1, 2 desired, then sintered at high temperature (about 2100 ° C.) in a vacuum oven.
- the plates 1, 2 are then ground on a flat grinding machine with a diamond grinding wheel.
- the other two faces of the plates 1, 2 will also be smoothed and polished to the extent that they will also be brought into contact with other plates also smoothed and polished as will be seen in the examples described below.
- polishing operations can be carried out for example according to the following sequence:
- the seal is made without filler material which ensures a corrosion resistance of the device, strictly equivalent to that of the ceramic material used;
- the device is, depending on the conditions of implementation, easily dismountable and remountable, allowing, if necessary, all the desired cleaning interventions,
- the system being, according to the conditions of implementation, assembled at ordinary temperature and without particular conditions, it allows easy impregnation, by any means known to those skilled in the art, of the circulation circuit by a possible catalyst necessary for the desired reaction.
- Example 1 Silicon carbide heat exchanger illustrated by the diagrams of Figures 1 to 4.
- Two silicon carbide plates 1, 2 are produced by machining in pre-pressed blanks, by isostatic pressing at 1400 bars for example.
- the upper plate 1 comprises flanges 7, for example ANSI standard, necessary for the connection of the exchanger, made during the machining in green.
- the circulation circuit 6 of the fluid to be treated is machined in the lower plate 2, raw, as defined by those skilled in the art for the proper implementation of the application.
- the two plates 1, 2 are sintered, ground, smoothed and polished on the faces intended to be in contact.
- the techniques used for sintering, grinding and polishing are well known in the manufacture of silicon carbide parts.
- the plates 1, 2 are then applied against each other so as to ensure sealing by adhesive bonding the parts that are in contact.
- the thus glued plates form a first sealed module M comprising the circuit of the fluid to be treated.
- Another plate 3 intended to ensure the circulation of the coolant, is made of a suitable material for the application:
- the plate 3 is machined by the same technique as the plate 2 in order to produce the circuit 8 for circulating the coolant.
- the plate 3, FIGS. 1 and 3 comprises connection flanges also made by conventional techniques for treating the ceramic.
- This plate 3 is then assembled on the module M, FIG. 4.
- This assembly will be made as a rule by conventional methods: bonding or seals 9 for example, insofar as, as a rule, the coolant is not corrosive. and compatible temperatures of known materials.
- the principle used is the same as in the first example above, the only difference is that the ceramic plates 10, 20 are arranged to allow the entry of the two fluids to give rise to the reaction desired chemical.
- the plate 10 comprises the connection flanges 107.
- the plate 20 comprises the fluid circuit 60.
- the plate 3 and the flanges 30 perform the same function as the plate 3 and the flanges 30 of FIGS. 3 and 4 relating to the exchanger thermal.
- This type of reactor is particularly well suited to the production of reactors for small flows. Indeed, this low flow rate, associated with the excellent thermal conductivity of SiC requires only a relatively short reaction length, and therefore leads to limited size plates, typically a few tens or hundreds of cm 2 . Such surface values are very compatible with easy and inexpensive polishing.
- Example 3 Ceramic heat sink for electronics (cooling of electronic components) illustrated in FIGS. 7 and 8:
- Two ceramic plates 100 and 200 are produced by machining in pre-pressed blanks (as in the previous examples), by isostatic pressing at 1400 bars for example.
- the upper plate 100 is made of an electrically insulating ceramic, for example alumina or aluminum nitride.
- the lower plate 200 is made of the same ceramic as the upper plate 100, or silicon carbide if a better thermal conductivity is necessary to promote the evacuation of calories.
- the heat transfer fluid circulation circuit 600 is machined in this lower plate 200, as defined by those skilled in the art for the proper implementation of the application.
- the plate 200 also comprises the flanges 207, for example to the ANSI standard, necessary for the connection of the dissipator.
- the two plates 100, 200 are sintered, ground, smoothed and polished on both sides intended to be in contact.
- the electronic components are mounted on the top plate 100, and are cooled by the liquid circulating in the dissipator.
- the ceramic plates having received a polishing treatment, and then possible additional treatments (cleaning) according to the process show a high level of adhesion when they are applied against each other. the other, and the connection between the two plates is leakproof.
