An electric heating device includes a casing which forms inlet and outlet openings for a fluid to be heated and a circulation chamber communicating with the inlet and outlet openings, and into which at least one PTC heating element with at least one PTC element projects which is, for electrical contact, provided with contact strips which are exposed in a connection chamber which is separated from the circulation chamber by way a partition wall. The casing further forms a control chamber for accommodating a control device which, with regard to controlling, is coupled to the at least one PTC heating element. An integrally formed casing base member, made of a plastic material, forms the partition wall and walls which circumferentially surround the circulation chamber and the connection chamber.

A fluid-heating device for heating fluid includes: a heater having a heat generating part, the heat generating part being configured to generate heat upon application of current; an electric component configured to control the application of the current to the heater; a tank having an opening portion, the tank being configured to accommodate the heat generating part; a top-plate portion configured to close the opening portion of the tank, the top-plate portion being configured to form a fluid chamber through which the fluid flows; and a first communication port and a second communication port configured to allow the fluid to flow through the fluid chamber; wherein the electric component is provided on an outer side of the fluid chamber along the top-plate portion.

A PTC heating element includes a heating element casing that fits, as a structural unit, at least one PTC element and contact plates that energize the PTC element and that form contact strips for an electrical plug connection in order to electrically connect electrodes that are electrically connected to the PTC element. The PTC element is covered with an insulation layer at least on one of its two main side surfaces. In order to provide such a heating element casing that is inexpensive to produce and of a light-weight configuration, the PTC heating element comprises an injection-molded plastic frame which encloses the insulation layer only at the edge and which defines oppositely disposed frame openings, behind which the PTC element with its main side surfaces is located.

A PTC heating element comprises at least one PTC element and two conductor paths which are assigned to different polarities and which are electrically conductively connected to the PTC element and are provided with connection elements for the electrical connection of the PTC element. The PTC heating element has improved heat discharge due to the provision of an electromagnetic shielding which is formed from a fluid-permeable metal structure and which surrounds the PTC element and the conductor paths.

An operator configurable radiant heating system is provided for a motor vehicle. That operator configurable radiant heating system includes a plurality of docking points provided at different locations within the motor vehicle and a radiant heating panel configured for docking with any of the docking points of the plurality of docking points. A related method is also disclosed.

The present invention relates to a vehicular heating device comprising: a vehicular engine cooling unit for connecting an engine, a water pump, and a radiator on a first cooling water circulating line to cool the engine; and a vehicular indoor space heating unit for connecting the engine, the water pump, and a heater core on a second cooling water circulating line to heat an indoor space of the vehicle, wherein the vehicular heating device comprises a heating means mounted on the second cooling water circulating line to heat cooling water supplied to the heater core. According to the present invention, the heating performance of the cooling water, which is supplied to the heater core during an initial cold start of the vehicle is improved, thereby increasing the indoor heating efficiency of the vehicle during a winter season.
