Electric heating device

An electric heating device, comprising:

• a heater housing in which a partition separates a circulation chamber,
• through which a medium to be heated can flow,
• from a connection chamber in which electrical connections of a PTC heating element are exposed,
• wherein the PTC heating element has at least one PTC element and strip conductors lying against opposed sides of the PTC element,
• wherein at least one of the strip conductors is covered by an electrical insulation layer, wherein the PTC heating element is introduced into a recess which is provided in a heating rib projecting from the partition into the circulation chamber, wherein the heating rib comprises a heating rib frame with at least one window in which the insulation layer is exposed to said medium, wherein the heating rib frame of the heating rib is connected to the partition,
• wherein the heating rib frame forms two opposite windows in which one of the electrical insulation layers is respectively exposed, and wherein each strip conductor is respectively covered by an electrical insulation layer.
