Electric heating device

An electric heating device comprising:

• a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat;
• PTC heating devices that protrude from the partition wall of the housing as heating ribs in a direction toward the heating chamber, wherein each PTC heating device comprises at least one PTC element and conductor tracks that are electrically connected in the connection chamber for energizing the PTC element with different polarities and that are connected to the PTC element in an electrically conductive manner;
• wherein the PTC heating devices are plug-connected in receptacles formed on the partition wall and are supported with oppositely disposed ends thereof on a base of the heating chamber, the base being disposed opposite to the partition wall;
• wherein alternately oppositely disposed edge surfaces of the heating chamber are associated with plug-connected PTC heating devices that are provided one behind the other so that a meandering flow channel is formed in the heating chamber;
• wherein a face surface of each PTC heating device is received by a respective receptacle, which is C-shaped in cross section and protrudes from an edge surface of the housing;
• and
• wherein the face surface of the PTC heating device connects mutually oppositely disposed main side surfaces of the PTC heating device to one another.
