  • Electric heaters as heaters for internal combustion engine and hybrid motor vehicles or as Voütropicungen for electric vehicles are basically known.
  • This PTC elements are used, which are energized and thereby emit heat.
  • the heating elements are arranged between heat-conducting elements of the heating and release their heat via these heat-conducting elements to the environment.
  • the entire heater is located in the interior of the vehicle-mounted airflow. In (pure) electric vehicles only electric (Voii-) heaters are used.
  • the electrical heating element according to the invention for a motor vehicle heater is provided with - a ceramic substrate,
  • an electrical heating conductor which is arranged on the ceramic substrate, a passivation layer deposited on the ceramic substrate and covering the electrical heating trace, and
  • a ceramic cover member disposed on the passivation layer and sealingly connected to the passivation layer against ingress of gases and / or fluids.
  • the electric heating element according to the invention has two ceramic elements, namely a ceramic substrate and a ceramic cover.
  • On the ceramic substrate is an electrical heating conductor, which is covered by a passivation layer, which is preferably designed as a glass passivation.
  • On the passivation layer is the ceramic cover element, which is hermetically sealed with the passivation layer, i. H. is tightly connected against the ingress of gases and / or fluids or moisture.
  • the two-sided cover of the electric heating element by the ceramic elements creates a montagefreundltches and touch-safe heating element, which is also protected from damage.
  • the electrical heating element according to the invention can be easily introduced between heating elements, wherein the ceramic elements protect the electrical heating conductor from damage.
  • the Schuleiterbahn is designed as a resistance paste pressure.

Abstract

L'invention concerne un élément chauffant électrique pour un chauffage de véhicule à moteur, lequel présente un substrat en céramique (12) sur lequel est disposée une piste thermoconductrice électrique (14). Le substrat en céramique (12) et la piste thermoconductrice (14) sont recouverts en particulier par une couche de passivation en verre (20). Sur la couche de passivation en verre (20) se trouve un élément de couverture en céramique (22) qui est relié de manière hermétiquement étanche à la couche de passivation (20) en particulier par un procédé de brasage au verre.
