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.
Claims13
An electric heating device comprising:
- a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat, wherein at least one receiving pocket protrudes into the heating chamber as a heating rib;
- a PTC heating device received in the housing, the PTC heating device including at least one PTC element and conductor tracks for energizing the PTC element with different polarities, the conductor tracks being electrically connected to the PTC element and being electrically connected in the connection chamber, wherein the PTC element and the at least one conductor track are received in a heater casing, and wherein the heater casing is pressed into the receiving pocket subject to plastic deformation of the heater casing and/or the receiving pocket;
- and
- wherein the heater casing is cold-welded to the receiving pocket.
A method for producing an electric heating device, comprising:
- providing a housing with 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 protrudes;
- introducing a PTC heating device into a heater casing of the PTC heating device, the PTC heating device including at least one PTC element and conductor tracks for energizing the PTC element with different polarities which are electrically conductively connected to the PTC element;
- and
- pressing the heater casing into the receiving pocket subject to plastic deformation of at least one of the heater casing and the receiving pocket;
- and
- wherein the heater casing is cold-welded to the receiving pocket.
