Definitions

  • the present invention relates to a heat-generating element of a heater for air heating, comprising at least one PTC element and voltage applied to opposite side surfaces of the PTC element electrical conductor tracks.
  • a heat-generating element is, for example, from the date of the present applicant EP 1 061 776 known.
  • the heat-generating element is used in particular in a heater for a motor vehicle and comprises a plurality of successively arranged in a row PTC elements which are energized via parallel to each other, flat on opposite sides of the PTC elements voltage applied electrical conductors.
  • the conductor tracks are usually formed by parallel metal strips.
  • the heat-generating elements thus formed are used in a heating device for air heating in a motor vehicle, which comprises a plurality of layers of heat-generating elements, abut on the opposite sides of heat-emitting elements. These heat-emitting elements are applied via a holding device in relatively good heat-transfer contact to the heat-generating elements.
  • a holding device of the heating device is formed by a frame in which a plurality of mutually parallel layers of heat-generating and heat-emitting elements are spring-loaded.
  • the heat generating element is formed by a plurality of in a row in a plane successively arranged PTC elements, which are also referred to as ceramic elements or PTC thermistors, which are energized on opposite side surfaces by voltage applied to these tracks.
  • PTC elements which are also referred to as ceramic elements or PTC thermistors, which are energized on opposite side surfaces by voltage applied to these tracks.
  • One of the tracks is formed by a circumferentially closed profile.
  • the other trace by a metal strip, the intermediate storage of an electrical insulating layer on the circumferentially closed supported metallic profile.
  • the heat-emitting elements are formed by lamellae arranged in several parallel layers, which extend at right angles to the metal profile which is closed at the circumference.
  • a plurality of circumferentially closed metal profiles formed in the manner described above are provided, which are arranged parallel to each other.
  • the lamellae partially extend between the circumferentially closed profiles and partially protrude beyond them.
  • the electrical traces must be in good electrical contact with the PTC elements. Otherwise, there is the problem of increased contact resistance, which can lead to a local overheating, in particular when using the heat-generating elements in auxiliary heaters for motor vehicles because of the high currents. By this thermal event, the heat-generating element can be damaged.
  • the PTC elements are self-regulating resistance heaters that provide lower heat output at elevated temperature, so local overheating can interfere with the self-regulating properties of the PTC elements.
  • a heat-generating element of a heating device for air heating as well as a corresponding heating device are given, which provide increased security.
  • the present invention aims to increase the safety with regard to a possible electrical flashover.

  • the ceramic plate of the insulating layer can be applied as a relatively smooth component with high accuracy over the entire surface of the electrical conductor. If desired, the insulating layer can be bonded directly to the electrical conductor. To improve the thermal conductivity between the conductor track and the insulating layer of the adhesive should be provided in a thin layer as possible below 20 microns.

Accordingly, a portion of the support frame extends between the opposing projecting ends of the contact sheets. In other words, the holding frame is also provided between the opposing contact plates, so that the current-carrying parts of the heat-generating element held within certain limits in the position frame in the height direction are. Compliance with the Isolierspaltes between the contact plates and the material of the position frame can be effected, for example, by an insulating spacer means which is provided in the insulating gap between the PTC element projecting edge of the contact plate and the material of the position frame.

  • the boundary edges are mainly used for the exact positioning of the insulating layer in the width direction of the position frame.
  • the positioning frame preferably also extends in the height direction, i. in a direction transverse to the bearing plane of the PTC element extending boundary webs. These boundary webs project beyond the boundary edges and serve to position a heat-emitting element adjacent to the heat-generating element.
