Definitions

  • the invention relates to an electric heater with the features of claim 1 and a method for producing such a heater.
  • electrical heating devices include, for example, heating cartridges that are used, inter alia, for heating a wide variety of components in the automotive industry.
  • Known heating cartridges have an often tubular metal shell, which defines a pipe interior.
  • an electrical heating element is arranged, which is usually designed as Bankdrahtwicklung, which may be arranged in particular on a winding body and is advantageously electrically insulated from the metal shell, in particular by a Isolierstoffhellung-.
  • connecting wires which are in electrical contact with the heating wire winding, can be led out of the metal jacket.
  • An example of this basic structure for example, the DE 20 2011 105 348 U1 or the DE 20 265 960 U1 ,
  • the heating cartridges known from the prior art prove in practice, especially in heating cartridges, where high currents are necessary to provide the desired heating power and thereby determine the geometry of the connecting wire, as not ideal.
  • the problem in this case to ensure a safe and reproducible electrical contact between the electric heating element and the connecting wire.
  • the object of the invention is therefore to provide a particular with regard to this electrical contact improved heating cartridge.
  • the electric heating element according to the invention comprises at least one connecting wire and at least one electrical heating element wound at least in sections on a wound body, for example made of ceramic, wherein the winding body has at least one channel in which at least one end of an electric heating element wound on the winding body is accommodated.
  • a wound body for example made of ceramic
  • the winding body has at least one channel in which at least one end of an electric heating element wound on the winding body is accommodated.
  • an at least partially closed channel which is separated in the thus executed sections in each direction perpendicular to the direction of the channel by a wall from the environment, as e.g. can be generated by a hole in the winding body.
  • said components are disposed within a metal shell and embedded in an insulating layer, which in particular prevents an unwanted short circuit to the metal shell.
  • the leads can also be configured differently and a two-sided or one-sided connection of the electric immersion heater by means of connecting wires is possible ,
  • the connecting wires can also be bent outward or angled.
  • the connecting wire has along its course at least one point or a portion at which the cross-sectional geometry of the connecting wire of the cross-sectional geometry of the connecting wire at least with respect to the contour of the cross-section of the connecting wire, in other words with respect to the contour of the local direction of the Further, a section of the at least one connecting wire is received in the channel, so that in the channel, an electrical contact between the received end of the electric heating element and the recorded portion of the connecting wire.
  • contours that can be converted into one another by means of a geometric similarity illustration are to be understood as different contours.
  • the invention makes use of the knowledge of the inventor that the requirements for the cross-sectional geometry of the lead wire, resulting from the adaptation to the use of a particular current, for example, a given cross-sectional area, which is necessary to unwanted heating of the electric immersion heater in a unheated section to avoid, within the bobbin no inventory have more.
  • a higher current load, which is usually to be avoided, is acceptable there because, on the one hand, heating power is usually to be provided on the one hand, and the winding body is dimensioned and configured in any case such that local overheating is also ruled out.
  • a portion of the lead wire may be configured to meet the conductor geometry requirements outside the coil body while introducing a much thinner portion into the coil body channel that defines the maximum cross-sectional area of that portion, and there the desired electrical contact to the electric heating element, in particular a heating or resistance wire, with which the winding body is wound, in particular produces a radial compression of the electric heating cartridge, resulting in a very good and intimate electrical contact.
  • the portion of the connecting wire accommodated in the channel of the wound body has a smaller cross-sectional area than at least one other portion of the connecting wire.
  • the electric heating cartridge is pressed or compacted, in particular highly compressed.
  • the connecting wire has at least one cross-sectional area with a rounded contour and / or at least a cross-sectional area having a contour which is angular. It is particularly preferred if the region of the connecting wire, which is received in the channel of the winding body, has cross-sectional surfaces with a rounded contour. In this way, for example, a possible risk of breakage for the winding body, but also a risk of damage to the electric heating element by acting thereon edge of the connecting wire during pressing can be significantly reduced, while in the region of the connecting wire, which runs outside the winding body, an optimal space- or land use is possible.
  • the connecting wire in particular in its section extending outside the winding body, is at least partially surrounded by an insulating layer, which in particular is made of PTFE, PFA, FEP, polyimide, silicone, rubber, glass silk or a plastic can.
  • an insulating layer which in particular is made of PTFE, PFA, FEP, polyimide, silicone, rubber, glass silk or a plastic can.
  • the length of the portion of the connecting wire, which is received in the channel of the winding body is limited by a stop. In this way, an exact and reproducible insertion depth of the inserted into the channel of the winding body portion of the lead wire can be ensured, which unifies the contact between the lead wire and electric heating element and thus homogenized the properties of the electric immersion heater within a production series or a model.
  • the cross-sectional area of the connecting wire has a recess on at least one side, which is preferably adapted to the cross-section of the electrical heating element, the electrical contact between connecting wire and electrical heating element can be improved even further and further standardized, so that the property fluctuations of the electric heating cartridges of a given type can be further reduced. It is particularly preferred if the recess is produced by stamping or material removal by a shaping process.
  • the portion of the connecting wire not received in the channel of the winding body runs at a smaller distance from a metal jacket of the electric heating cartridge than the portion of the connecting wire accommodated in the channel of the winding body, it is possible to remove the outside of the winding body optimal space available to adapt the running there sections of the connecting wires, so as to allow the highest possible current flow.
