Definitions
- the present invention relates to a coil adapted to generate a magnetic field particularly suitable for the generation of intense magnetic fields and / or for withstanding significant mechanical forces and a method of manufacturing said coil.
- magnets consisting of one or more coils crossed by an intense electric current, said coils being cooled.
- the said coils generally consist of cylindrical tubes obtained in a conductive or superconductive material and cut along a generally helical cut line, with a constant pitch or not, to form turns.
- These intense field coils are currently almost exclusively used in laboratories of intense magnetic fields and could, for example, be usefully used in NMR machines according to the acronym "Nuclear Magnetic Resonance" for the realization of magnetic resonance imaging.
- These NMR machines usually have a tunnel-like structure with a central space reserved for the patient and an annular structure which integrates on the one hand means for creating in the central observation space a homogeneous and intense main magnetic field and on the other hand radiofrequency excitation means and radiofrequency signal processing reemitted by the body of the patient placed in the central observation space, in response to the excitation sequences.
- these machines In order to differentiate the radiofrequency signals emitted in response and to create an image, these machines also comprise so-called gradient coils for superimposing on the intense homogeneous field additional magnetic fields the value of which depends on the spatial coordinates of their place of application.
- Such an NMR machine is for example described in the French patent application FR 2 892 524.
- Magnetic field gradient coils or generating an intense magnetic field are subjected to intense electromagnetic forces that induce mechanical forces leading to deformation of the turns of the coil. The deformation of the turns can induce a lack of reliability of the machine and / or an inhomogeneity of the detrimental magnetic field for the realization of good quality imaging.
- Document US Pat. No. 2,592,802 describes an induction coil consisting of a tube obtained in a conductive material and cut along several generally helicoidal lines to form turns which are separated by a vertical portion ensuring a separation between the turns. Said separation part is cut to form a pair of spacing members on either side of a cylindrical hole in which is advantageously inserted a rod obtained in an insulating material.
- the document EP 0146494 describes an induction coil consisting of incomplete annular cuts made in a cylindrical tube, said incomplete annular cuts being connected by two vertical cuts. This type of induction coil is intended to allow the displacement of the spacers in the nuclear reactors and is not intended to receive high intensity currents for the formation of intense fields.
- US 3,466,743 discloses a coil consisting of a tube obtained in a conductive material and cut along a generally helicoidal line to form turns, said turns passing through holes initially made along the tube, the cutting line being filled with an insulating material to prevent any deformation when the coil is traversed by currents of very high intensity.
- One of the aims of the invention is therefore to remedy all these drawbacks by proposing a coil or a set of coils capable of generating a magnetic field and particularly suitable for generating an intense magnetic field. and a method of manufacturing said coil of simple design, inexpensive and providing a recovery of the forces induced by the electromagnetic forces on the coils of the coils.
- a method of manufacturing a coil capable of generating a magnetic field said intense field when traversed by an electric current comprising a step of forming turns in a cylindrical tube remarkable in that it comprises at least one step of forming at least one boss on at least one turn of said coil and at least one hollow of corresponding shape in an adjacent turn so that the boss s' extended to the right of said hollow, to resume the mechanical forces induced by the electromagnetic forces and mechanical forces of thermal origin.
- the latter comprises a preliminary step of optimizing the boss or bosses and the hollow (s).
- This optimization step consists at least in the following steps of: geometrical modeling of the tubes and cutouts defining the turns, determination of a mesh of the turns and the boss or bosses and the corresponding hollow or holes from the previous geometric model, simulation of thermal overheating and / or electromagnetic fields and / or mechanical behavior from the mesh, comparison of thermal and / or electromagnetic fields and / or mechanical deformations with those of a so-called reference model which does not include bosses.
- the successive bosses on a given turn can be advantageously spaced angularly to optimize the recovery of electromagnetic forces and avoid too large turns deformations.
- Said bosses are formed such that the concavity of each boss has the same orientation.
- the bosses are formed such that the concavity of at least one boss has an orientation opposite to the orientation of the concavity of at least one second boss.
- the turns, bosses and corresponding depressions are formed by cutting a cylindrical tube along a generally helical cut line.
- the width of each turn is constant or variable.
- an insulating material may be deposited in the cutting line between two consecutive turns.
- Another object of the invention relates to a coil or a set of coils capable of generating a magnetic field said intense field when (s) is (are) traversed (s) by an electric current, said coil consisting of at least one tube or tube assembly obtained in a conductive and / or superconductive material and cut along a generally helical line, characterized in that at least one turn of the coil comprises at least one boss extending to the right of a hollow formed in an adjacent turn to recover the mechanical forces induced by the electromagnetic couples on the turns.
- the successive bosses on a turn are staggered angularly to optimize the recovery of electromagnetic forces and avoid too large turns deformations.
- Said coil comprises a plurality of bosses and recesses whose concavity is oriented in the same direction.
- said coil comprises a plurality of bosses and depressions and in that the concavity of at least one boss has an orientation opposite to the orientation of the concavity of at least one second boss.
- Each boss has for example a general semi-circular or triangular or square or rectangular shape.
- the width of each turn is constant or variable.
- said coil comprises an insulating material filling the cutting line.
- Said coil is obtained either in a cylindrical tube of electrically conductive material or in a superconducting material.
- FIG. 1 is a perspective view of a coil according to the invention
- FIG. 2 is a perspective view of an alternative embodiment of the coil according to the invention.
- FIG. 3 is a partial perspective view of a coil according to the invention.
- FIG. 4 is a perspective view of a detail of the coil according to the invention shown in FIG. 3 before compression of the insulating plates;
- FIG. 5 is a perspective view of a detail of the coil according to the invention shown in FIG. 3 after compression of the insulating plates
- FIG. 6 is a diagram showing the steps of manufacturing a coil. according to the invention
- the coil 1 consists of a generally cylindrical tube 2 in which turns 3 have been formed by cutting, by any suitable means, a helical cutting line 4, said tube 2 being obtained in a electrically conductive material such as copper or a solid superconductor for example and said coil possibly comprising an insulating material filling the cutting line 4 in a manner well known to those skilled in the art.
- a plurality of turns 3 of the coil 1 comprises a boss 5 extending to the right of a recess 6 of corresponding shape formed in an adjacent turn 3 to take up the mechanical forces induced by the couples electromagnetic on turns 3 when traversed by a current of high intensity.
- all the bosses 5 and the recesses 6 of the turns 3 are generally aligned along a longitudinal line. Nevertheless, it is obvious that the bosses 5 of two adjacent turns may be angularly offset.
- the upper part of the coil arbitrarily represented vertically in FIG. 1, comprises a plurality of bosses 5 and recesses 6 whose concavity is oriented in the same direction towards the lower end of said coil 1.
- lower part of the coil 1 also comprises a plurality of bosses 5 and recesses 6 whose concavity is oriented in the same direction, for example towards the upper end of said coil 1, opposite the direction to the orientation of the concavity bosses 5 of the turns 3 of the upper part of said coil.
- the coil 1 may comprise only one boss and a single hollow or a plurality of bosses and recesses on one or more turns, the concavity of at least one boss may have an opposite orientation to the orientation of the concavity of at least one second boss, without departing from the scope of the invention.
- each boss 5, and therefore each recess 6, has a generally semicircular shape; however, it is obvious that each boss 5 may have any shape such as a triangular shape, square or rectangular, for example.
- each turn 3 is constant; however, the width of all or part of the turns may be variable, the width of the space between two adjacent turns being constant including at the bosses 5 and hollows 6.
- the coil may consist of a plurality of tubes 2 without departing from the scope of the invention.
- the latter is constituted in the same manner as previously of a generally cylindrical tube 2 in which turns 3 have been formed by cutting along a helical cutting line 4.
- f (t) may be substituted by f (t, ⁇ ) to adjust the angle of the cut along Oz in a radial plane.
- the bosses 5 and the recesses 6 will then have a generally conical shape, that is to say that their edges will not be perpendicular to the axis of revolution of the tube 2.
- the coil according to the invention is formed in the same manner as above a generally cylindrical tube 2 in which turns 3 were formed by cutting next a generally helical cut line 4, said turns comprising bosses 5 and recesses 6 of corresponding shapes. Said bosses 5 and said recesses 6 have a trapezoidal shape.
- the section of the bosses 5 and recesses 6 may decrease from the outer wall to the inner wall of the tube 3. This form of bosses and recesses is particularly suitable for the implementation of thin turns and / or for the insulation setting.
- insulating plates such as pre-preg fiberglass boards, according to the pre-impregnated acronym acronym; said plates having a shape of annular section, can be positioned between two adjacent turns 3.
- the turns 3 are separated by any appropriate means (FIG. 4).
- These insulating plates 7 are advantageously constituted by at least 3 superimposed thin insulating sheets 8.
- the insulation once compressed, with reference to Figure 5 conforms to the drawing of the turn 3 without breaking.
- this superposition of thin sheets of insulation 8 provides a reduction of internal stresses to the insulator.
- the intermediate sheet 8 is never in direct contact with the metal or the superconducting material of the turns 3 thus ensuring increased electrical safety.
- the insulating plates 7 may comprise any number of sheets 8 and that they may be obtained in any insulating material without departing from the scope of the invention. It will be observed that the setting of insulating plates between bosses 5 and successive recesses 6 can allow the passage of cooling liquid at the level of said bosses 5 and said recesses 6 (FIG. 5), the coil 2 which does not contain any insulation at the bosses 5 and recesses 6 having 9 days allowing a flow of a liquid or a cooling fluid between the inside and outside of the tube and vice versa. Said cooling liquid consisting for example in water in the case of resistive magnets, or in helium or liquid nitrogen in the case of superconducting materials.
- a geometric model of the turns is produced using computer-aided design software.
- CAO computer-aided design software
- CATIA ® or Open Cascade marketed by the company Open Cascade SAS A mesh of the coils 3 and 5 or the projections and recesses or 6 matching is performed, in a step 200, from the CAD model by means of a suitable software such as, for example, CATIA ® software or mesmer Ghs3d ® from the company Distene, then in a step 300, a simulation of thermal heating and / or electromagnetic fields and / or mechanical behavior corresponding to the previous mesh is performed.
- Said thermal heating and / or electromagnetic fields and / or mechanical deformations obtained by this mesh are compared, in a step 400, with a so-called reference model having no bosses and hollows. Modifications can be made if necessary on the geometry of the turns. The procedure is then repeated until obtaining a suitable model.
- the same procedure can be used for the optimization of mechanical stresses.
- the steps 100 to 400 are then repeated until a mesh is obtained having a minimum thermal heating and / or a homogeneous or almost homogeneous magnetic field and / or a minimization of the displacements consecutive to the electromagnetic and thermal loadings.
- the parameterized curve corresponding to the selected cutout thus determined is then transmitted to a digital cutting machine, which proceeds to cut the turns 3, bosses 5 and recesses 6 in the tube 2, in a step 500.
- the bosses 5 and the recesses 6 cooperate to ensure a centering of the turns.
- the tube 2 may consist of a set of tubes, said tube 2 or the set of tubes being obtained in a solid conductive and / or superconductive material.
- the tube 2 may consist of a support tube obtained in copper or stainless steel for example and on which are secured, for example by welding, son or superconducting cables.
- the support tube provided with the bosses 5 and recesses 6 according to the invention then has a function of taking up electromagnetic forces and a function of heat dissipation in case of "quench", that is to say, back to the accidental normal state or not of the superconducting part.
