Abstract: An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket, protruding into the heating chamber as a heating rib tapering towards its lower, closed end protrudes. A PTC heating element includes at least one PTC element and conductor tracks for energizing the PTC element with different polarities. The conductor tracks are electrically conductively connected to the PTC element and are electrically connected in the connection chamber. A pressure element is received which holds heat extraction surfaces of the PTC element abutted against oppositely disposed inner surfaces of the receiving pocket. The pressure element includes a sheet metal strip which, by punching and bending, forms spring segments protruding from the plane of the sheet metal strip. The spring elements are provided in a planar manner distributed over a heat extraction surface of the PTC element provided adjoining the respective pressure element.

Abstract: An electric heating device comprises a housing with a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one PTC heating device protrudes as a heating fin in the direction toward the heating chamber. The PTC heating device comprises at least one PTC element electrically connected to conductor tracks in the connection chamber. A temperature sensor is connected, in terms of data, to a control device and is accommodated in a sealed manner in a temperature sensor receptacle which is formed in a wall delimiting the heating chamber. The temperature sensor is accommodated in a sliding manner in the temperature sensor receptacle. A support prevents the temperature sensor from sliding out of the temperature sensor receptacle and/or directly plugs a temperature sensor contact element of the temperature sensor in the connection chamber into a printed circuit board.

Abstract: A heat-generating element of an electric heating device includes a PTC element, conductor tracks abutting surfaces of the PTC element, and an adhesive which connects the conductor tracks to the PTC element. The conductor track has several contact projections which protrude from an abutment surface of the conductor tracks. The contact projections form a contact surface which abuts the surface in an electrically conductive manner with a free space between the surface and the abutment surface, in which the adhesive is accommodated. Also disclosed is a method in which the contact projections are formed from initially planar conductor track, an adhesive is applied to the abutment surface between the contact projections, a masking covering the contact surfaces is removed, and the conductor track is glued to a PTC element with the adhesive accommodated between the surface and the abutment surface.
