Abstract

See full text

The disclosure relates to a PTC heating module for heating a fluid and a method for producing such a PTC heating module. The PTC heating module includes a plurality of PTC thermistors having main surfaces disposed opposite to one another and spaced apart relative to one another in a thickness direction. The PTC thermistors are arranged between two contact plates next to one another transversely to the thickness direction and spaced apart relative to one another. The main surfaces of the PTC thermistors are electrically contacted with a contact surface of the two contact plates. At least one dielectric function element is arranged between the two contact plates and laterally sealingly engages about the respective PTC thermistors to at least partially fill a hollow space between the two contact plates and facilitate enlarging a creepage distance between the two contact plates within the hollow space.
