Abstract: An electrical heating device comprises two heating chambers between which an electrical heating assembly is formed. Via a distributor a flow of a medium to be heated entering the electrical heating device in the inflow direction is divided into a first partial flow and a second partial flow. The first partial flow flows through the first heating chamber, while the second partial flow flows through the second heating chamber. For this purpose, the distributor has a distributing body, which may be configured as a conical bod that is rotationally symmetrical about an axis of symmetry. The axis of symmetry may be parallel to an inlet axis. Alternatively, the distributing body can also be configured as an overflow edge.

Abstract: An electrical heating device comprises an electrical heating assembly and a control device adapted to control the electrical heating assembly and a housing base part that is adapted to accommodate the control device. The housing part is connected to a housing cover to form a housing sealed from the environment. The control device and the electrical heating assembly are accommodated in the housing to create a compact design and the best possible EMC protection.

Abstract: An electrical heating device for heating a liquid medium includes a first heating chamber, a second heating chamber, and an electrical heating assembly which is provided between the first heating chamber and the second heating chamber and which is coupled to the first heating chamber and the second heating chamber in a heat-conducting manner. In order to provide an electrical heating device which can be easily adapted to different heating powers and/or operating voltages, the first heating chamber has a first channel section, and the second heating chamber has a second channel section. The first channel section and/or the second channel section form a flow connection between the two heating chambers which passes through the plane containing the electrical heating assembly and the length of which can be varied in a direction transverse to the plane containing the electrical heating assembly.
