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 protrudes into the heating chamber as a heating rib. A PTC heating device with at least one PTC element and conductor tracks for energizing the PTC element with different polarities, which are electrically conductively connected to the latter and which are electrically connected in the connection chamber, are received in the housing. The PTC element and at least one of the conductor tracks are received in a heater casing. The heater casing is pressed into the receiving pocket subject to plastic deformation of the heater casing and/or the receiving pocket.

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 protrudes into the heating chamber as a heating rib that may taper towards its lower closed end. A PTC heating element is received in the receiving pocket. The PTC element includes at least one PTC element and conductor tracks which energize the PTC element with different polarities which are electrically conductively connected to the PTC element, and which are electrically connected in the connection chamber. A pressure element also is received in the receiving pocket. Heat extraction surfaces of the PTC element are held in the receiving pocket abutting against oppositely disposed inner surfaces of the receiving pocket. The pressure element has at least one cambered surface segment projecting toward the inner surface or toward the PTC element.
