  • Publication number: 20220053610
    Abstract: An electric heating device includes a housing with a partition wall which separates a connection chamber from a heating chamber for emitting heat. At least one heating assembly housing projects from the partition wall in the direction of the heating chamber. The heating assembly housing supports at least one PTC element and strip conductors in an electrically insulated manner A housing wall projecting from the partition wall and delimiting the connection chamber and/or the heating chamber and/or the heating assembly housing is connected to the partition wall by material bonding, which may be by induction soldering. Also disclosed is a method of making an electric heating device.

  • Publication number: 20210354530
    Abstract: A PTC heating assembly includes a heating cell comprising a PTC element and conductor elements electrically abutting the PTC element. The heating cell is accommodated in a heater housing. The heater housing is manufactured with undersize relative to the heating cell so that the heating cell, after insertion into the heater housing, is held under pretension between mutually opposing walls of the heater housing. Accordingly, in the method according to the invention, the heater housing is elastically widened when the heating cell is inserted into the heater housing.
