Abstract: An electric heating device may include a heating volume, at least two heating modules arranged in the heating volume, an electrically conductive control housing, a power electronics, and an electrically conductive conductor arrangement. The control housing may delimit a control volume and may have a bottom that delimits the heating volume. The conductor arrangement may include an intermediate part electrically connected to the bottom and to an electrically conductive outer shell of each of the heating modules. The heating modules may each extend into the control volume through an associated passage opening of the bottom. The outer shell of each heating module may extend through an associated arrangement opening of the intermediate part. The conductor arrangement may include a cover covering the intermediate part. A closure bend of the intermediate part may extend through a cover opening of the cover and engage with the cover to form a form closure.

Abstract: An electric heating device for a motor vehicle may include a heating volume and at least two spaced heating modules. A flow path of a fluid may lead through the heating volume. At least two spaced heating modules may be arranged in the heating volume. The at least two spaced heating modules may extend in a longitudinal direction. The at least two spaced heating modules may be spaced apart from one another in a transverse direction extending transversely to the longitudinal direction.

Abstract: A heating arrangement may include at least one PTC heating device with at least one first PTC heating element. The PTC heating device includes at least one second PTC heating element that is distinct from the first PTC heating element, wherein the first and second PTC heating elements may be arranged in a through-flow direction next to one another. Alternatively, a further PTC heating device with at least one second PTC heating element that is distinct from the first PTC heating element may be provided, wherein the first and second PTC heating devices may be arranged in the through-flow direction next to one another.
