Electric heating device and method for its manufacture

A method for the manufacture of an electric heating device comprising 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 protrudes, a PTC heating element being accommodated in the housing, the PTC heating element including at least one PTC element and conductor tracks for energizing the PTC element with different polarities, the conductor paths being electrically conductively connected to the PTC element and which being electrically connected in the connection chamber, and a pressure element accommodated in the housing and holding heat extraction surfaces of the PTC element abutted against oppositely disposed inner surfaces of the receiving pocket, the method comprising:

• introducing the PTC heating element into the receiving pocket;
• then
• introducing a pressure element into the receiving pocket for heat-conductive abutment of the heat extraction surfaces of the PTC element against the oppositely disposed inner surfaces of the receiving pocket and then, at least one of
• 1) deforming deformation projections so as to be distributed in a planar manner over the heat extraction surfaces, and
• 2), when the connection chamber is closed with a housing cover, providing a holding web on the housing cove in abutment against the PTC heating element.
