Definitions

  • the present invention relates to a flexible heating element that can be used in many applications and more particularly intended to be incorporated in a heated seat of land or air vehicles, for example.
  • Such heating elements are widely used in the form of heating wires for this type of use.
  • product ranges have been developed from stranded or un-stranded copper wires whose linear resistivity generates a heating power correlated with the current intensity according to the Joule effect.
  • the object of the invention is therefore to provide a flexible heating element having good fatigue strength, good flexibility, good conductivity and good resistance to oxidation, all for a minimal footprint.
  • the conductive core is further protected by the armature against abrasive wear or any risk of cut.
  • the heating element according to the invention can find a use for heating seats of land or air vehicles, for the manufacture of heating pipes, for the manufacture of heating textiles and in particular heating clothing, for the manufacture of resin heating molds, as well as in a corrosive medium. It can also be used for heating flywheels or other accessories and for the realization of any type of heating structures.
  • This heating element consists of a conductive core 1 formed of a plurality of copper wires, slightly stranded. These copper son are fine and in particular have a diameter of between 20 and 100 microns, preferably between 50 and 80 microns.
  • These son may be continuous filaments obtained by drawing, but may also be made of fibers agglomerated together by any means, and especially by spinning.
  • a material is conductive if it has a resistivity of less than 1000 ohms / m. However, it will be preferred to use materials having a resistivity of less than 300 ohms / m or even less than 200 ohms / m.
  • the second component of this element is a braided outer armature 2 formed from stainless steel wires. As can be seen in Figure 1, this element can be made simply by braiding the steel wires around the copper wire strand.
  • an outer frame in the form of a simple winding or a double wrapping or even a knit or more generally a knitting son, replacing the braided frame.
  • a conductive core of another electrically conductive material such as silver or aluminum, for example.
  • the conductive son may be covered with an insulating coating or not, such as an enamelled coating. The possible coating of these son is individual, because a global coating encapsulating or surrounding the entire core would significantly reduce its flexibility, which goes against the goals sought in the present invention.
  • This insulating coating has the advantage of avoiding the creation of a hot spot in case of accidental breakage of one of the son of the conductive core, while allowing the heating element to continue to operate with a light power. scaled down. In addition, this insulating coating has been found not to substantially reduce the resistivity of the assembly.
  • the coating of these wires may, in another embodiment, be made of metals such as nickel or tin, deposited by any suitable method, such as hot dip coating or electroplating.
  • Such a coating may also have for object the protection of the son of the conductive core against oxidation, especially when these son are copper or copper alloy.
  • the flexible heating element shown therein comprises a heat-stable core core 10 of a material such as aramids or PBO (para-phenylene-2,6-benzobisoxazole).
  • This core 10 has the function of increasing the mechanical strength and the creep resistance of the entire element to make it suitable for use in the context of fatigue stress or large mechanical stresses.
  • a conductive core 11 made of stranded copper wires, similar to the conductive core 1 of the first embodiment.
  • This conductive core 11 is in turn surrounded by a braided outer frame 12 made of stainless iron-chromium alloy.
  • the flexible outer armature according to the invention is made of a steel or a stainless alloy. It will be possible to use iron-chromium alloys with more than 10.5% chromium or iron-nickel alloys, especially when it is desired to control the spring effect.
  • the flexible heating element is covered with an insulating sheath of plastic, such as PTFE, for example.
  • This sheath can in particular be deposited by extrusion, or plasticization.
  • the presence of the stainless steel under this sheath brings the additional advantage of facilitating the stripping thereof, especially during the welding operations necessary for the connection of the element.
  • the heating element according to the invention can be used in applications that do not require a resistance of the material beyond 400 ° C.
