Definitions

  • the invention relates to a heating register with several individual PTC elements that electrically form a PTC element group with each other interconnected and selected in this way from a production of PTC elements are that the PTC element group with respect to an electrical parameter adheres to a specified group tolerance.
  • Such PTC heating registers are used, for example, to build heating blocks used for electric heaters used in automotive heating systems for heating a vehicle interior come.
  • the heating register consists of the individual PTC elements, the electrically e.g. are connected in parallel.
  • DE 44 34 613 A1 is a strip-shaped PTC heating register for discloses this purpose, the individual PTC elements at a distance inserted side by side in openings of a sealing frame and by two sheets lying on both sides are held.
  • the invention has the technical problem of providing a PTC heating register based on the type mentioned, in which the predetermined Group tolerance with regard to the relevant electrical parameter is observed, all places for PTC elements can be filled and as far as possible no functional PTC elements from production for the Must be discarded in the heating register.
  • This heating register includes a PTC element group with a fixed number of PTC elements, i.e. all the places reserved for the same are also occupied. to Not only those PTC elements are used in the heating register approved, the individual tolerance of the electrical Characteristic within one of the given group tolerance Single tolerance range, but also PTC elements the production, the individual tolerance of which lies outside of this range.
  • PTC elements are special for the heating register selected as a group that is electrically interconnected comply with the specified group tolerance. This can e.g.
  • Fig. 1 shows a strip-shaped PTC heating register of known Structure as described in DE 44 34 613 A1 cited above.
  • On Sealing frame 1 e.g. Made of soft plastic material with multiple openings 2 provided, in the example shown, these are three openings, one in corresponding number of individual PTC elements 3a, 3b, 3c introduced is.
  • the PTC elements 3a, 3b, 3c are in it through a lower plate 4 and one removed in FIG. 1 for the purpose of recognizing the PTC elements 3a, 3b, 3c, upper sheet held.
  • the sheets also serve that Heat transport and the electrical contacting of the PTC elements 3a, 3b, 3c.
  • the three PTC elements 3a, 3b, 3c with each other electrically in parallel to a corresponding PTC element group connected has to adhere to a certain tolerance referred to as group tolerance.
  • group tolerance a certain tolerance referred to as group tolerance.
  • the frequency distribution has its maximum at the tolerance value 0%, ie the frequency maximum lies with those manufactured PTC elements whose electrical resistance or conductance has the target value specified for production.
  • PTC elements with resistance or conductance values that deviate from the nominal value. Although their number decreases with increasing distance of the actual resistance or conductance from the target value, overall there is nevertheless a considerable number of PTC elements with their resistance or conductance, for example in the hatched area B L of FIG. 2 lie, ie lie below the target value by more than a lower limit value T U , or lie in the area B R shaded in FIG. 2, ie lie above the target value by more than an upper limit value T O.
  • the lower and the upper limit value T U , T O are set so that this individual tolerance range B M corresponds to the predetermined group tolerance, ie when the individual tolerances of all three PTC elements 3a, 3b, 3c on lower limit value T U , this leads to an overall tolerance value at the lower limit of the specified group tolerance, and analogously, if the individual tolerances of the three PTC elements 3a, 3b, 3c are at the upper limit value T O , an overall tolerance value at the upper limit Limit of the specified group tolerance.
  • all manufactured PTC elements can be used in that when selecting the three PTC elements 3a, 3b, 3c for the heating register, their individual tolerances are observed and a tolerance deviating in one direction for one of the PTC elements by selecting one or more of the other PTC elements with tolerance deviating in the other direction is compensated.
  • any PTC element can first be picked out as the first PTC element 3a used from a complete set of manufactured PTC elements. If this comes from the mean single tolerance range B M of FIG. 2, there is practically complete freedom of choice for the second PTC element 3b to be used.
  • the second PTC element 3b is preferably selected from the respective other of these two regions B L , B R.
  • the third PTC element 3c is then suitably selected either from the middle area B M with a small tolerance or from one of the two areas B L , B R with a higher tolerance , so that overall the tolerance of the three selected and electrically interconnected PTC elements 3a, 3b, 3c is within the predetermined overall tolerance.
  • each of several PTC heating registers of a heating block built with it the desired tolerance with regard to the electrical resistance or conductance also ensures that the electrical resistance or conductance of the Total heating blocks is within a predeterminable tolerance.
  • heating registers with any build a different number of PTC elements If necessary can be used for easier selection of the PTC elements with suitable Tolerance value a pre-grouping of all manufactured and functional PTC elements in predefinable groups with different Tolerance intervals may be provided. If a manufacturing system Number of such groups and the associated tolerance intervals as well as the Number of PTC elements to be inserted in the heating register known this is able to select and insert the Make PTC elements largely automated.
  • Heating registers complete freedom of choice from the entire set of manufactured PTC elements, all PTC elements can be seen can be used for the production of appropriate heating registers, too those with high tolerance, i.e. high deviation of the electrical Characteristic of the setpoint.
