Abstract: A heat-generating element for an electric heating device includes a heating element casing which comprises a casing element formed from a ceramic material and a casing mating element formed from a ceramic material. The two casing elements bear against each other in a sealing manner and enclose, in a sealing manner between each other, a PTC element and conductor tracks. The conductor tracks bear, in an electrically conductive manner, against the PTC element and are assigned different polarities for energizing the PTC element. The heating element casing carries contact strips connected in an electrically conductive manner to the associated conductor tracks. At least one of the conductor tracks is formed by an electrically conductive element which is provided with through holes and which, in a height direction of the conductor track, comprises discrete points of support that bear against the PTC element and one of casing element and casing mating element. The present invention further relates to an electric heating device with at least one heater casing with a heat-generating element of the type described here that is arranged in a circulation chamber with a heating element casing joining at least one PTC element and contact strips energizing the PTC element as a structural unit. The heat generating element has the contact strips electrically connected to the PTC element projecting over itself. A partition wall separates the circulation chamber from a connection chamber of the heater casing. The contact strips of the PTC heating element protrude through the partition wall and are exposed and electrically connected.

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.

Abstract: A PTC heating device has a frame surrounding an accommodation space, at least one PTC element accommodated in the accommodation space, and conductor elements, which are connected to the PTC element in an electrically conductive manner and enclose the PTC element between them. Each of the conductor elements is surrounded by a frame segment. The frame segments are welded together to enclose the PTC element in the accommodation space. In the method according to the invention, injection molded plastic frame segments having interacting connection segments are connected to conductor elements. At least one PTC element is then introduced between the frame segments. The frame segments are approached to each other until the connection segments abut against each other. The connection segments are then melted. As a result of this melting, the frame segments are approached further to each other until the conductor elements abut against the PTC element.

Abstract: The invention relates to a frame (3) for an electric heating device (1), comprising at least one housing (7) intended to receive a heating element (5), said housing being defined by a plurality of longitudinal walls (23, 25) forming an insertion path for a heating element, and said insertion path being defined longitudinally by a back wall extending opposite an opening through which the heating element can be inserted into the housing. According to the invention, at least one of the longitudinal walls comprises a displacement reducing element (10) projecting from the wall. The displacement reducing element (10) comprises a ramp (11) that slopes gradually into the housing, towards the opposite longitudinal wall, said displacement reducing element (10) being arranged such that the downstream end (14, 15) thereof extends at a distance from the back wall (21).
