Definitions

  • the invention initially relates to a method for producing an electrically conductive resistance layer, in which an electrically conductive material is applied by means of thermal spraying on a non-conductive substrate.
  • Such a method is from the DE 198 10 848 A1 known.
  • a heating element is described, which is produced by applying band-shaped layers of an electrically conductive and a resistance-forming material on surfaces of a substrate by means of arc sputtering or by plasma spraying.
  • a release liner is previously applied to the substrate by means of a printing process.
  • the separating layer is made of such a material that in those places of the Substrate on which the separation layer is present, the electrically conductive material does not adhere.
  • the known method has the disadvantage that it is relatively complicated and therefore the parts with the electrically conductive resistance layers are relatively expensive. In addition, only more or less flat parts can be provided with an electrically conductive layer with the known method.
  • the present invention therefore has the object of developing a method of the type mentioned so that the production of an electrically conductive layer on a substrate easier and cheaper possible and also complex shaped objects can be provided with such an electrically conductive resistance layer.
  • the electrically conductive material of which the resistance layer is made is applied flat and generally uniformly on the non-conductive substrate.
  • the application by means of thermal spraying ensures a high adhesion of the electrical conductive material on the non-conductive substrate.
  • a variety of materials can be applied quickly and very evenly in this way on the non-conductive substrate.
  • the applied electrically conductive material is removed at certain points by means of a suitable device.
  • a complex shaping of the electrically conductive layer is made possible in only two steps.
  • the partial removal of the material layer takes place by means of laser radiation or by means of a water jet or by means of a powder sandblast.
  • the material When using laser radiation, the material is heated so much that it evaporates.
  • the use of a laser beam has the advantage that with him very quickly very high energies can be coupled into the electrically conductive material, so that it evaporates immediately.
  • This instantaneous evaporation of the electrically conductive material ensures that only comparatively little heat is coupled into the substrate present under the electrically conductive material. This is therefore not damaged in the method according to the invention.
  • the evaporation has the advantage over incineration that essentially no residues remain in the evaporated areas on the substrate and so their insulation is very good.
  • the electrical resistance of the electrically conductive resistance layer is detected at least indirectly during the area-wise removal of the material layer. In this way, a precise quality control is already possible directly during the production of the electrically conductive layer.
  • an actual value of the electrical resistance of the electrically conductive resistance layer is compared with a desired value and the electrical resistance of the electrically conductive layer is changed by removal of additional electrically conductive material in regions such that the difference between the actual value and the desired value is reduced.
  • Such deviations may, for example, be caused by the fact that different amounts of the electrically conductive material reach the substrate during spraying of the thermally conductive material so that the resulting electrically conductive layer has a different thickness at one point than at another location.
  • deviations of the actual value of the electrical resistance of the electrically conductive layer from the desired value can be compensated for with an accuracy of +/- 1%.
  • the partial removal of additional electrically conductive material may include a shortening or lengthening of the electrically conductive layer and / or the variation of the width of the electrically conductive layer.
  • the material layer is removed in such a way that a desired melting point in the sense of a fuse is produced at at least one point of the electrically conductive layer.
  • a desired melting point in the sense of a fuse is produced at at least one point of the electrically conductive layer.
  • Such integrated fuse increases the safety when using the electrically conductive resistance layer.
  • the fuse can be integrated into the electrically conductive resistance layer virtually without additional costs and additional time.
  • the material layer is removed in such a way that the electrically conductive resistance layer is at least partially meandering. This allows the formation of the longest electrically conductive resistive layer on a small area.
  • the electrically conductive material preferably comprises bismuth, tellurium, germanium, silicon and / or Gallium arsenide. These materials have proved to be particularly favorable for the application by means of thermal spraying and the subsequent processing by means of laser radiation. In addition, with these materials, the relevant known technical effects can be realized.
  • Plasma spraying, high-speed flame spraying, arc spraying, autogenous spraying, laser spraying or cold gas spraying has proved to be advantageous for the application of the electrically conductive material to the substrate.
  • the electrically conductive material is applied in this way and the material layer is partially removed in such a way and comprises such a material that an electrical heating or an electrical cooling layer is formed.
  • the "Peltier effect" is advantageously utilized.
  • the local electrical resistance of the electrically conductive resistance layer is adjusted by a local heat treatment.
  • a local heat treatment By heating locally oxides can be registered in the layer, which has an effect on the local electrical conductivity of the material. This allows a special precise and fine adjustment of the electrical resistance.
  • the electrically conductive resistance layer is sealed.
  • This has advantages in particular with a porous substrate (for example metal with Al 2 O 3 intermediate layer). Sealing reduces the risk of electrical breakdown due to Humidity, especially at high voltage.
  • a material for sealing silicone, polyimide, or water glass the latter on sodium or potassium-based. The application can be done by dipping, spraying, brushing, etc. The seal of the seal is best when the sealant layer is applied under vacuum.
  • non-conductive substrate is also glass or glass ceramic in question.
  • the electrical resistance layer can be applied permanently, especially by plasma spraying.
  • the good insulating effect of glass makes grounding in the operation of the resistive layer superfluous.
  • special high-temperature glass such as Ceranglas (R).
  • the invention also relates to a heating and / or cooling device with a non-conductive substrate and an applied to the substrate by thermal spraying electrically conductive resistance layer.
  • the production costs for such a heating and / or cooling device can be reduced if the resistance layer comprises an electrically conductive material initially applied by thermal spraying, which was then removed in regions by means of laser radiation and thus brought into a desired shape.
  • FIG. 1 and 2 shows the production of a tubular water heater:
  • an electrically conductive material layer 14 is applied to a tube 12 made of a high-temperature resistant and an electrical insulator material ( Fig. 1 ).
  • the application takes place in the present exemplary embodiment by means of a device 16, with which germanium particles 18 are sprayed onto the tube 12.
  • the application is carried out by cold gas spraying (also "gas-dynamic Powder coatings called ").
  • the unmelted germanium particles are accelerated to speeds of about 300 - 1,200 m / s and sprayed onto the tube 12.
  • the germanium particles 18 and also the surface of the tube 12 deform.
  • the impact breaks up surface oxides on the surface of the tube 12. Micro-friction due to the impact increases the temperature at the contact surface and leads to micro-welds.
  • the acceleration of the germanium particles 18 takes place by means of a delivery gas, the temperature of which can be slightly increased.
  • the germanium powder 18 in no case reaches its melting temperature, the temperatures arising at the surface of the tube 12 are relatively moderate, so that, for example, a comparatively inexpensive plastic material for the tube 12 can be used.
  • plasma spraying, high-speed flame spraying, arc spraying, autogenous spraying or laser spraying for applying the electrically conductive material to the substrate can also be used instead of the cold gas spraying.
  • germanium, bismuth, tellurium, silicon and / or gallium arsenide are also suitable, depending on the desired technical effect.
  • the coating of the tube 12 with the germanium particles 18 is carried out initially so that gradually the entire surface of the tube 12 is covered with the germanium material layer 14 (see. Fig.1 ).
  • this material layer 14 does not yet have the desired shape:
  • an electrically conductive resistance layer must be made, which extends in the manner of a spiral in the circumferential direction around the tube 12. This will, as out Fig. 2 It can be seen, by means of a laser device 20, a laser beam 22 directed to the still "shapeless" material layer 14, that a spirally around the tube 12 extending portion 24 is created in which the sprayed electrically conductive material 14 is no longer present.
  • the laser device 20 on the one hand and a device, not shown in the figure, with which the tube 12 is held, are thereby moved so that a continuous working process by the laser device 20 is possible.
  • the actual electrical resistance WIST (see. Fig. 5 ) of the electrically conductive resistance layer 26 is less than the desired per se electrical resistance WSOLL.
  • the in Fig. 4 The lower connecting region 34 of the electrically conductive resistance layer 26 is therefore processed by the laser beam so that its width decreases, so that additional material is evaporated.
  • the electrically conductive resistance layer 26 extends by a dimension d1 (cf. Fig. 4 and 5 ) and, as a result, the actual electrical resistance WIST increases until it approximately corresponds to the desired resistance WSOLL.
  • the final position of the boundary line of the lower electrical connection 34 carries in Fig. 4 the reference numeral 42.
  • the electrically insulating intermediate layer 46 is applied in the further course of the manufacturing process. Then the process described above is repeated, i. H. again electrically conductive material is applied by means of thermal spraying onto the non-conductive intermediate layer 46 in such a way that a second material layer formed therefrom substantially does not yet have the desired shape. This is then processed by laser radiation and partially evaporated (reference numeral 24b) such that a second electrically conductive resistance layer (26b) is formed in the desired shape.
  • the material of the electrically conductive layer is selected such that instead of an electrical heating layer, an electrical cooling layer is formed.
  • the temperature of the heating layer is monitored by a ceramic switch.
  • a ceramic switch This is understood to mean a non-mechanical switch which has an element whose conductivity depends to a considerable extent on its temperature.
  • a bimetal switch can be used.
