Abstract
An electric heating device has a housing with inlet and outlet openings for a fluid to be heated. The housing has a circulation chamber for passing the fluid to be heated through the housing and a connection chamber for the electrical connection of at least one PTC heating assembly. The PTC heating assembly comprises at least one PTC element strip conductors which energize the PTC element with different polarity and which are heat-conductively coupled to at least one surface of the housing delimiting the circulation chamber. Measures are taken to disturb a laminar boundary layer of the fluid to be heated on at least one of the heat-emitting surfaces. A method is provided for processing at least one heat-emitting surface formed by the housing to provide a structure that disturbs the laminar boundary layer of the fluid to be heated.
