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.

The description relates to a vehicle heating system having at least one heat transfer device through which air can flow to be heated and at least one heating device which is attached to the heat transfer device and which each involves at least one heating element arranged between two contact plates, said heating element being held by a positioning frame which is attached to one of the contact plates. The contact plates of the heating devices are each held in a positioning frame to which they are attached.

The present invention relates to a heating device (10), in particular to an electric heating device for a motor vehicle, having a heat exchanger housing (12), heat exchanger core (14) which absorbs heat at a heat input face, and a printed circuit board (20) having electronic components (16, 18) for controlling the heating device (10), wherein the printed circuit board (20) is arranged on an outer side (22) of the heat exchanger housing (12), wherein a temperature sensor (24) is arranged on a side (26) of the printed circuit board (20) which faces the outer side (22) of the heat exchanger housing (12), wherein connecting means (28) are provided which connect the temperature sensor (24) in a heat conducting fashion to the outer side (22) of the heat exchanger housing (12), and wherein the heat input face of the heat exchanger core (14) is connected in a heat-conducting fashion to the heat exchanger housing (12), with the result that a continuous short heat bridge, running through the interior of the heat exchanger housing (12), to the connecting means (28) is generated.

An electric heating device may heat an air flow through a duct of a ventilation, heating and/or air-conditioning installation of an automotive vehicle. The heating device may include at least one heating module that is contained in a heating body. The heating body may include a housing for controlling and supplying electrical power to the at least one heating module. The housing may include, in its interior, a printed circuit board from which a power supply connector and a control connector protrude. The housing may also include a power supply opening such that the power supply connector emerges from the housing and a control opening such that the control connector emerges from the housing. The housing may include a skirt that protrudes in parallel to the control connector on the periphery of the control opening. The skirt may be formed as a single part with the housing.
