Definitions

  • the subject of the present invention is a process for the manufacture of an assembly comprising a body and a device for the thermal regulation of this body, as well as the assembly obtained.
  • the invention relates to the field of devices whose implementation has the effect of acting on the temperature of the body with which they are associated to raise it according to need.
  • the expressions “regulate the temperature” or “control the temperature” will be used in the following and should be considered equivalent.
  • Such an invention relates to very many activities and could find an application, for example, in the field of aerospace where dashboard temperature control systems are implemented, in the medical sector through means of control of sample analysis devices sensitive to temperature variations, or to provide equipment for de-icing surfaces, melting snow, or suitable for the field of industrial food, pharmaceuticals, etc.
  • systems of the patch or heating mat type intended to be applied, or even glued, to the body in question are proposed.
  • These systems are conventionally made up of a resistive electrical track encapsulated between several layers of a polymer or a mineral insulator such as mica, providing electrical insulation.
  • Their flat, slim design guarantees a safe and even temperature distribution and is suitable, for example, for mounting between two flat surfaces or on a worktop. They can also be used to heat only one small area and are able to withstand extremely high temperatures when they include mica.
  • the various layers of materials allowing its electrical insulation end up giving the existing thermal regulation devices a large volume, and consequently a large overall size.
  • the same also applies to the electrical connection members with which they may be provided.
  • thermal regulation systems adapted to the aerospace sector available on the market are those resulting from the assembly of a conductive track with materials compatible with vacuum, such as polyimide films.
  • materials compatible with vacuum such as polyimide films.
  • shape and the size of such systems can be handicapping for an association with often very miniaturized organs or components intended to be installed on spacecraft.
  • the object of the present invention is to provide an alternative solution to those currently known, making it possible to overcome all the drawbacks identified above.
  • the object of the invention is to provide a solution making it possible to overcome the problems resulting from the large size and the standardized shapes or structures exhibited by the thermal control systems of a body proposed by the manufacturers today, while maintaining their overall performance in terms of efficiency, longevity and cost.
  • such a process has the advantage of integrating from its design a thermal regulation device directly on the support or the body whose temperature it must control, whatever the shape, the dimensions of the latter or the nature of the material composing it.
  • the thermal regulation device will have a very thin thickness, and will perfectly match the shape of the body in question, thus allowing a uniform distribution of the temperature on the latter and therefore an optimized action.
  • the etching step can be carried out, depending on the case, by laser, by machining, or by chemical attack.
  • each layer of electrically insulating polymer prefferably a wet route, a dry route, a thermal route or by thermal spraying.
  • each layer of electrically insulating polymer can be carried out by a technique alternatively of electrolytic deposition, static or dynamic chemical deposition, physical or chemical deposition in the vapor phase assisted or not by plasma, gilding, silver plating, tin plating by immersion, flaming, dynamic spraying by cold gas.
  • the method according to the invention also assumes the use of a resistive alloy chosen from the list comprising nickel-chromium such as inconel (registered trademark), copper-nickel, such as constantan, and any other alloy resistive.
  • nickel-chromium such as inconel (registered trademark)
  • copper-nickel such as constantan
  • any other alloy resistive any other alloy resistive.
  • an additional characteristic of the present process is defined by the fact that an electrically insulating polymer chosen from the list comprising the following polymers is used: polyimide, polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), silicone, resin, thermoplastic.
  • PTFE polytetrafluoroethylene
  • PEEK polyetheretherketone
  • the invention has also provided for the possibility of using a body made of a material suitable for 3D printing.
  • the invention also relates to an assembly formed by a body and a device for modifying the temperature of the body obtained by implementing the method as defined above.
  • this same assembly can be characterized in that it is connected to a system for remote control of the temperature to be imparted to said body.
  • the present method comprises a first step consisting in depositing on a flat portion 7 of a body 1 a layer 2 of a polyimide powder by flame deposition.
  • a layer 3 of inconel (registered trademark) is then deposited by a technique of vapor phase deposition (PVD) on the layer 2 of polyimide.
  • PVD vapor phase deposition
  • a laser etching of layer 3 of inconel (registered trademark), carried out during a subsequent step, has the effect of producing an electrical circuit 4.
  • the method according to the invention advantageously makes it possible to overcome the drawbacks of the state of the art, and to equip all types of surface, that is to say, whatever its form or the material of which it is made, of a thermal regulation device formed of a resistive track encapsulated between two layers of an electrically insulating material.
