CERAMIC ROD AND AUXILIARY HEATER OR LIQUID HEATER COMPRISING A CERAMIC HEATING ROD

摘要

This disclosure relates to a ceramic rod having a ceramic PTC heating conductor and a ceramic insulation layer, which is sintered with the PTC heating conductor. According to this disclosure, the PTC heating conductor has a transition temperature that does not exceed 300° C., and preferably does not exceed 200° C. This disclosure also relates to the use of a ceramic rod, which comprises a ceramic PTC heating conductor and a ceramic insulation layer, which is sintered with the PTC heating conductor, as a heating rod for an auxiliary heater or a liquid heater in a motor vehicle. This disclosure also relates to an auxiliary heater for heating an air flow and a liquid heater comprising a heating rod, which is a ceramic rod, which has a ceramic PTC heating conductor and a ceramic insulator sintered therewith.
