BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preheater apparatus for a vehicle, and more particularly, to a preheater apparatus for a vehicle in which the heat core is made of a module and the overall size can be adjusted according to the number of mounts of the heat core.

Generally, a vehicle is provided with a heating device that utilizes the thermal energy of cooling water heated by the engine to heat the room, dehumidify the vehicle front glass, or remove the property.

Since the cooling water flowing around the engine flows into the heater after the engine is started, it takes a long time until the cooling water is once heated and the room is heated. As a result, there has been a disadvantage that it must be kept cold for a certain period of time after starting.

Recently, a variety of preheaters have been developed to solve such problems, and a preheater incorporating a PTC element (positive temperature coefficient thermistor) has been proposed.

There is a problem in that it is difficult to manufacture a preheater of various sizes because a heat core including a PTC device can not be divided. Therefore, there is a need to improve this.
