Abstract

An electrical heating device includes a frame and a layer structure arranged in the frame and comprising layers of corrugated ribs and PTC-based heat generating elements. The electrical heating device includes at least two corrugated-rib elements. The frame has two frame elements forming openings and at least one frame intermediate element arranged between them. A frame, formed solely by the frame elements, forms an accommodation space extending in the passage direction of the medium to be heated, which is appropriately formed for the accommodation of a layer structure with a level of corrugated ribs and heat generating elements. A frame, formed by the frame elements and the frame intermediate element, forms an accommodation space extending in the passage direction of the medium to be heated, which is formed for the accommodation of a layer structure with several levels of corrugated ribs and heat generating elements.
