<p>The present invention provides a PTC rod assembly, including PTC elements, for use in a pre-heater for a vehicle, and a pre-heater for a vehicle including the same. The PTC rod assembly comprises a lower PTC rod constructed in the form of an elongated channel with an open side; an anode terminal placed within the lower PTC rod while being enclosed by an insulator made of an insulating material such that the anode terminal is not in contact with the lower PTC rod; PTC elements constructed to generate heat upon application of electric power thereto and coupled to be in contact with one side of the anode terminal; heat transfer blocks made of a material with high thermal conductivity and brought into contact with the other side surface of the anode terminal; and an upper PTC rod coupled to cover the open side of the lower PTC rod. According to the PTC rod assembly and the pre-heater for a vehicle including the same, the insulator for fixing the anode terminal has a more simplified structure and is conveniently manufactured and the efficiency of transferring the heat generated by the PTC elements is improved.</p> |
