An electric heating device, particularly for a motor vehicle, is provided that has at least one heating element disposed in a housing, whereby the housing has a housing cover and/or a housing base with at least one opening through which the at least one heating element is disposed protruding at least in sections, whereby a sealing element in which the at least one heating element is disposed is provided in the at least one opening in the housing cover and/or in the housing base.

A heating module includes: an insulating case; at least one heat emitting element that is supported by the insulating case; at least one terminal plate that is arranged in the insulating case to contact the heat emitting element; and a ceramic insulator that is arranged on an outer surface of the terminal plate.

An electric heater for an automobile vehicle, with at least one heating element and with at least one circuit board, whereby the circuit board has at least one contact area through which an electrical connection between a heating element and a power supply can be realized. The heating element has at least one PTC-heating element, whereby the heating element can be clipped to the circuit board via a connector clip, and whereby the connector clip has two flexible extensions, which are arranged opposed to each other.

An electric heating device includes an electric control device with a control housing that is in structural unity with a housing of a power section. The power section has a frame forming a heating chamber. At least one PTC heating device with at least one PTC element and conductor elements is provided in the heating chamber. The control housing forms a chamber which is separated from the frame by a partition wall. A heat sink projects from the partition wall into the power section. The electric control device has a printed circuit board and at least one power switch which generates a power loss and which is connected in a heat-conducting manner to a surface of a heat sink. An electrically insulating layer and a spring element, which holds the power switch applied under pretension against the surface of the heat sink, are provided between the power switch and the heat sink.

A ceramic heater having an enlarged windward area includes a conductive heat sink, at least one positive temperature coefficient (PTC) heating element, and an electrode plate. The conductive heat sink includes a cooling fin. The at least one PCT heating element is disposed on one side of the cooling fin. The electrode plate is disposed on the other side of the cooling fin. A conductive terminal protrudes from one end of the electrode plate. The conductive terminal includes a warped section and a flat section. A portion of the warped section and the flat section extend in a direction perpendicular to an extending direction of the electrode plate. Accordingly, heat dissipation is accelerated, a windward area is enlarged, and the effect of blowing out a hot airflow is enhanced, thereby avoiding a temperature rise of the conductive terminal.

The invention relates to a heating device for heating the interior of a motor vehicle, comprising a plurality of heating modules arranged in at least one heating unit, each heating module comprising at least one heating resistor, at least one heat exchanger configured for delivering heat generated by the heating resistor to an airflow, and a rectangular frame surrounding the at least one heating resistor and the at least one heat exchanger, each frame having openings in opposed frame legs, wherein in the at least one heating unit the frame legs, comprising openings, of adjacent heating modules face one another and electrical connection elements reaching through the openings electrically connect the heating modules to one another.
