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.
