Abstract (en)
[origin: US2021247105A1] 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.
