PTC PTC PTC rod of PTC heater

摘要

The present invention relates to a structure of a PTC heater of a PTC heater disposed in a plurality of PTC (Positive Temperature Coefficient) heaters for heating air for heating a vehicle, comprising: at least one PTC element disposed at a predetermined interval in one direction; A pair of aluminum panels disposed on the upper and lower sides of the PTC device, respectively, and pressed against the PTC device to electrically connect the PTC device; And a molding body that molds the PTC element and a pair of aluminum panels to fill a void space formed between the pair of aluminum panels and the PTC element. According to the present invention, a PTC element and a pair of aluminum panels are joined together in a state in which the PTC element and the aluminum panel are joined together, And it is possible to prevent the PTC device from moving due to vibration during running of the vehicle by providing a more rigid coupling by using the PTC element fixing portion formed on the aluminum panel.
