摘要:
A device for exchanging heat for motor vehicles, having at least one first component connected to an electrical power supply and whose temperature varies dependent on current flowing through the component, at least one second component including at least one first and at least one second part element each of which are at least indirectly conductively connected to the first component, wherein at least one part element includes a first connecting means and at least one electrical contact means which is at least indirectly conductively connected to at least one part element of at least one second component and serves to connect an electrical power supply wherein the contact means includes at least one second connecting means. Both of the connecting means include at least one flat portion and the first and the second connecting means interlock so as to result in a form-fitting connection between the first and the second connecting means and electrical contact is established at least between a primary surface of the flat portion of said first connecting means and a major face of the flat portion of said second connecting means.

摘要:
The invention relates to a heating assembly comprising at least one PTC element, in particular for a motor vehicle. According to the invention, the PTC element (2) is positioned between metal sheets (3, 4), which are used to make electrical contact, said sheets (3, 4) and the PTC element (2) are bonded by means of an adhesive (5) and the adhesive (5) has a minimum specific electrical resistance of 50 ohms×cm and a maximum specific electrical resistance of 500 ohms×cm. In addition, solder can be used as an alternative to the adhesive (5).
摘要:
A heating unit having a PTC element, in particular for a motor vehicle, with corrugated fins (6) arranged around the PTC element (2) for improved transfer of heat to air flowing through the heating unit. The heating unit has a plastic frame (7) which is of two-part design.
摘要:
A plug arrangement (8) for a heating unit having at least one PTC element, in particular for a motor vehicle. The PTC element (2) is arranged between contact plates (3, 4) which serve for the electrical connection, and one contact plate (3) is designed at one of its ends as a plug (5) which has a hollow-cylindrical shape.
摘要:
The invention relates to a controller for an electric auxiliary heater (1) of a motor vehicle air-conditioning system. The controller comprises a power supply cable (2), which provides energy and comprises a control cable for transmitting control signals to a regulator (5) for regulating the auxiliary heater (1). The invention is characterized in that the power supply cable (2) is also the control cable.
