  • Publication number: 20240019171
    Abstract: An electric heating device has a housing with inlet and outlet openings for a fluid to be heated. The housing has a circulation chamber for passing the fluid to be heated through the housing and a connection chamber for the electrical connection of at least one PTC heating assembly. The PTC heating assembly comprises at least one PTC element strip conductors which energize the PTC element with different polarity and which are heat-conductively coupled to at least one surface of the housing delimiting the circulation chamber. Measures are taken to disturb a laminar boundary layer of the fluid to be heated on at least one of the heat-emitting surfaces. A method is provided for processing at least one heat-emitting surface formed by the housing to provide a structure that disturbs the laminar boundary layer of the fluid to be heated.

  • Patent number: 11721456
    Abstract: A PTC heating element and an electric heating device containing such a PTC heating element are disclosed. The PTC heating element comprises two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween which is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers. The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element. The metallization provided on the other main side surface is assigned to only the other potential for energizing the PTC element. The metallization of the one main side surface of the PTC element and the metallization of the other main side surface of the PTC element are formed in such a way that the current path (P) through the PTC element is extended relative to the thickness (D) of the PTC element.
