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.

The invention relates to a heating module comprising a resistive heating element placed in a frame. The heating module constitutes a ready heating subassembly for heating a gas or a liquid, in particular for heating the air. The heating element is mounted to the frame by means of the at least two contacts arranged at opposite side walls of the heating element, wherein each contact comprises at least two brackets releasably coupled to a side wall, and at least one resilient element connected to the brackets and to at least one catch releasably coupled to the frame, wherein each resilient element, arranged in contact with a side wall of the heat ing element, is tensioned and exerts an expanding force acting on the connection of the contact with the frame and the heating element.

A PTC heating device exhibits a good degree of efficiency while providing good electrical insulation of the device's PTC element. The insulation of the PTC heating device comprises a film and a layer that is bonded to the film and made of brown compact which comprises non-sintered ceramic particles. Also disclosed is a method in which ceramic particles are provided with a binding agent, and the mass thus produced is applied in a planar manner onto a film and bonded to the film. The multilayer insulation thus produced is placed around the PTC element and the conductor tracks, and the binding agent is subsequently removed, at least in part.

Presented is a heating element, and method for producing same, comprised of strip material having a length, width and depth where the strip material is twisted at least once axially relative to its length and bent at least once across its width resulting in a generally flat profile. The twists and bends provide for expansion and contraction of the heating element and thereby provide stress relief during heating and cooling.
