Definitions

  • the present invention relates to transducers of the electrodynamic type which make it possible to emit acoustic waves in the sea, more particularly sound waves. These transducers are particularly useful in sonar technique.
  • Underwater acoustics are used for towed fish with electronic devices and various transducers that can operate in transmission, reception and possibly in both modes.
  • transducers of the electrodynamic type which comprise a flag driven by a voice coil located in an air gap.
  • This transducer according to the prior art, represented on the Figures 1 and 2 appended, comprises a body formed of a base 101 on which is fitted a shirt 102 surmounted by a cup 103. These different parts fit into each other so as to define cylindrical cavities of revolution around the l axis of the transducer, in which are inserted the other parts forming the transducer.
  • a first cylindrical cavity delimited between the base and the liner makes it possible to maintain a magnetic circuit formed of first and second pole pieces 104 and 105 in the form of rings centered on the axis of the transducer.
  • the first pole piece 104 is L-shaped with the inner branch of the L that overflows inside the central chamber of the transducer.
  • the second pole piece 105 is in the form of a flat washer. Both are kept separated by a set of magnets 106 on which they are tightened by the adjustment of the liner 102 in the base 101. In this way, a magnetic circuit is obtained which is only interrupted by a thin air gap 107 presenting the shape of a cylinder centered on the axis of the transducer and coming flush with the inner lateral surface of the cup 103.
  • the central space of the transducer body forms a second cylindrical cavity in which a mushroom-shaped core 108 is embedded by its central rod in the central circular opening of the pole piece 104.
  • the moving element of the transducer is formed by a hollow piece 109 having the shape of a dome covering a cylindrical portion which engages in the air gap 107. So that this piece is at the same time very solid, very light and very rigid, it is for example formed by a carbon fiber fabric embedded in a resin matrix.
  • the upper surface of the dome 109 is covered with a part 110 whose upper surface is substantially flat and which forms the radiative flag of the transducer. It is performed to be itself very light, for example syntactic foam.
  • Crown 110 therefore behaves like a piston whose lateral outer surface is cylindrical. This piston slides in a cylinder formed by the lateral inner surface of the cup 103, itself substantially cylindrical. These two parts, and more particularly the roof 110, are made to have an extremely small adjustment play, of the order of 0.2 mm for example. A mechanical filter is thus formed which slows down the propagation of the shock wave that may come from an eventual external explosion, by rolling in this gap the fluid in which the flag is bathed.
  • the upper part of the central space of the transducer body is filled with a fluid, an oil for example, adapted to both this protection and the propagation of acoustic waves.
  • a fluid an oil for example, adapted to both this protection and the propagation of acoustic waves.
  • the space 113 is closed at its upper part by a membrane 112, which is fixed on the periphery of the cup 103.
  • the lower part of the central space, opposite the part where the oil is, is filled with air.
  • another sealing membrane 115 made of rubber for example, which is much more flexible than the membrane 112 and which is a part fixed on the outer side wall of the roof 110 and secondly on the inner side wall of the cup 103. This attachment is made by pinching between the cup 103 and the shirt 102.
  • the external lateral surface of the flag is machined at this level to present a withdrawal relative to the nozzle 111, which has the reduced clearance described above, and form a free space for the membrane 115.
  • this assembly is stiffened by using a set of radial ribs 116 which are distributed on the inner periphery of the dome 109 and meet in a star below the lower part of the mushroom rod forming the core 108. These ribs slide in grooves 117 formed in the core 108 and in the first pole piece 104. These grooves are relatively wide at the core and are narrower at the pole piece to minimize the loss of magnetic flux, which can be reduced to a very low value. low of a few percent.
  • An axis 118 joins the center of the upper part of the dome 109 in the center of the star formed by the reunion of the ribs 116, below the lower face of the core 108.
  • This axis makes it possible at the same time to stiffen the assembly and to ensure its vertical centering with respect to the axis of the transducer.
  • the axis is fixed by its lower part in the center of a flat spring 119 itself fixed circumferentially in the lower part of the base 101.
  • This spring of the type known as "flector Is formed of a flexible and resilient washer carrying circumferential openings for allowing air to pass freely in the lower part of the central space of the transducer, between the two parts delimited by the plane of this spring. This spring ensures not only the centering, but it avoids the rotational movements of the moving element that would rub the ribs against the walls of the grooves in which they slide.
  • the driving action that makes it possible to move the dome / horn assembly along the axis of the transducer, to emit the acoustic waves, is obtained by the interaction between the magnetic field which circulates between the pole pieces and that delivered by a coil 120 wound on the lateral flanks of the lower cylindrical portion of the dome 109.
  • This coil is thus immersed in the air gap existing between the two pole pieces, which realizes the conventional diagram of an electrodynamic transducer, this coil is powered by means not shown in the figure and which are known in the art.
  • the ribs 116 also serve as a heat sink over the entire height of the coil 120, to dissipate the heat generated at this level by directing it to the other parts of the transducer.
  • the internal portion 114 delimited by the dome 109, the base 101 whose bottom is closed, the jacket 102 and the sealing membrane 115 is filled with air to allow the movement of the moving assembly, as has been seen above.
  • the mobile assembly When the transducer is immersed, under the effect of the hydrostatic pressure, the mobile assembly is sinking towards the bottom of the base 101 by compressing the spring 119 and the volume of air included in this portion 114.
  • This movement of course, to modify the electroacoustic characteristics of the transducer, in particular by modifying the respective positions of the coil and the pole pieces,
  • a compensation tank, or air chamber, 121 formed of a flexible bag, of rubber for example, subjected to the pressure of the marine environment and communicating with the part 114 by 122.
  • this inner tube is of toroidal shape and is located in another internal cylindrical cavity 123 which is delimited to the interior of the transducer by the walls of the jacket 102 and the cup 103. This cavity is itself toroidal and closed and surrounds the location of the flag 110.
  • openings 124 which allow the seawater to enter the cavity 123 and to compress the air chamber.
  • the inner tube is protected against mechanical external aggression by the walls of the cavity where it is located.
  • the diameter of the openings 124 is provided so that the shock waves from an eventual external explosion is attenuated through these openings, so that they do not present any danger of overpressure at the level of the inner tube.
  • These openings being round, their diameter may be greater than the thickness of the nozzle 111.
  • Such a transducer works perfectly, and resists for example the explosion of a ton of TNT located 30m from it.
  • the large current which then flows in the coil 120 causes a strong local heating which can not be dissipated properly by the means provided to date, in particular by the fins 116.
  • an electrodynamic transducer for underwater acoustics of the type comprising a body provided with pole pieces defining an air gap, a moving element provided with an extended dome by a cylinder supporting a sliding winding in this air gap, a flexible membrane ensuring the seal between the mobile equipment and the body by determining an inner part filled with air, and a flag overlying said dome and sliding in said body forming with it is a nozzle whose play value is set so as to protect said membrane against shock waves from explosions external to the transducer by laminating these shock waves in said nozzle, mainly characterized in that one said pole pieces is provided with at least one opening for the circulation of air inside the inner part for effectively cooling said winding.
  • it further comprises a conductive mass of the heat located between said pole pieces for draining the heat generated by the winding towards the outside of the transducer.
  • it further comprises a set of magnets placed between the pole pieces, characterized in that it further comprises a set of heat conductive masses interposed between the magnets.
  • said heat-conducting masses are made of aluminum.
  • the invention therefore proposes to eliminate the confinement of the air in this part 130 where the lower part of the coil 120 is immersed by forming holes 131 in the magnetic circuit 104.
  • These holes which are in this embodiment substantially vertical, therefore put in communication the portion 130 of the cavity 114 with the portion 126 of the same cavity, located at the bottom of the transducer under the core 108.
  • the communication additional created thus between the portion 125 of the cavity 114, located above the core 108 and this portion 126, allows a flow of air.
  • the latter having heated in contact with the coil 120 comes up in the part 125, cools by contact with the different massive parts of the transducer, then returns to the portion 126 of the cavity 114 down through the various orifices located in the central part of the transducer.
  • the invention proposes, in the exemplary embodiment shown on the Figures 3 and 4 , machining the lower portion of the housing 101, inside thereof at the portion 126 of the cavity 114, milling the interior thereof so as to disengage a circular shoulder 132 so that the holes 131 may themselves be machined vertically while opening into the portion 126 of the cavity 114.
  • the invention proposes, to improve the transfer of heat between the inside of the transducer, more particularly since the volume of air flowing at the portion 130 of the cavity 114, to place between the magnets 106 metal masses 135 which form thermal drains between the inside of the transducer and the external environment, by the intermediate of the shirt 102.
  • These metal masses are machined to provide a maximum thermal path to the heat released by occupying as much space as possible between the magnets. They are made of a material that is as much as possible heat conductor while remaining light enough not to weigh down the mass of the transducer. Among the most suitable materials for this use include aluminum. They are held, for example by gluing, on the pole piece 104, or possibly by pinching between the pole pieces 104 and 105 in the same manner as the magnets 106.
  • a transducer made in this way can withstand a current that can be at least 4 times higher than the admissible current in a transducer according to the prior art, without it being necessary to make any modification to the rest of the transducer, in particular to the coil, and obtaining identical performance without any degradation.
