Abstract
An electric heater, comprises a heating block held in a housing and including parallel layers of heat-emitting and heat generating elements. A grid arrangement covers the respective frame apertures in the housing and reinforces the housing. First struts of the grid arrangement, extending at right angles with respect to the layers, are assigned to the housing, and second struts extending parallel with respect to the layers are defined by the heating block. Moreover, a heat generating element of an electric heater, comprises a position frame made of an insulating material and defining receptacles arranged side by side each for at least one PTC heating element. The receptacles are arranged between conductor paths against which the PTC heating elements are placed in an electrically conductive manner.
