The present invention relates to a vehicle preheater having a rigid assembly structure, and more particularly, to a vehicle preheater having a rigid assembly structure including a heat rod assembly for preheating air in a vehicle interior using heat generated by a PTC element.

In a typical vehicle, a heating apparatus is installed that uses heat energy of cooling water heated by heat generated by an engine for heating indoors, dehumidifying or defrosting the windshield of the vehicle.

Such a heating apparatus has a long time until the cooling water is heated and the room is heated because the cooling water flowing around the engine flows into the heater after the engine is operated. Accordingly, there has been a disadvantage in that the cold state for a certain time after starting.

Recently, various preheaters have been developed to solve such problems, and as a representative structure, a preheater using a PTC (Positive Temperature Coefficient) device is disclosed in Korean Patent Publication No. 445722 (Applicant: Woori Industry). It is.

Referring to Figure 1 and 2 schematically described as follows.

As shown, the conventional vehicle preheater 1000 includes a heat rod assembly 100 including a PTC element, a heat fin assembly 200 arranged side by side on each side of the heat rod assembly 100, and And (-) terminals 300 arranged side by side with the heat fin assembly 200, and both side ends of the combination of the heat rod assembly 100, the heat fin assembly 200, and the (-) terminal 300 ( Frames 600 and 900, which are respectively coupled to the rear portion; The front housing 400 which combines the combination of the heat rod assembly 100, the heat fin assembly 200, (-) terminal 300, and the frame 600, 900 at both ends. ) And the rear housing 800 is configured.

In the aforementioned Korean Patent Publication No. 445722, the heat rod assembly 100 includes a channel type lower heat rod, an insulator disposed at the bottom of the lower heat rod, and is fixed in the longitudinal direction on the insulator. Although it comprises a (+) terminal, a PTC element coupled to the insulator via the (+) terminal, and an upper heat rod covering the opening of the lower heat rod, the heat rod assembly is configured as described above. Of course, a variety of other structures can be employed.

Meanwhile, as shown in FIG. 2, in the conventional vehicle preheater 1000, the heat rod assembly 100, the heat fin assembly 200, the (−) terminal 300, and the frame 600 arranged side by side are disposed. The coupling between the two ends of the assembly including the 900 and the front housing 400 and the rear housing 800 is a simple fitting method, so that the bonding strength was insufficient.

Specifically, in the front housing 400, the front end portions of the (+) terminal 130 and the (-) terminal 300 is fixed to the front housing 400 as it is fitted to the insulating plate. Then, the rear ends of the heat rod assembly 100, the heat fin assembly 200, the (−) ruler 300, and the frames 600 and 900 are aligned in a straight line and are fitted into the rear housing 800 as they are. It is. In particular, the rear ends of the frames 600 and 900 are fitted into the grooves 850 formed in the rear housing 800.

As such, in the related art, since the configuration for strongly coupling the combination of the negative terminal 300 or the heat rod assembly 100 and the heat fin assembly 200 in the transverse direction was insufficient, the main housing 400 and the 800 were used. There was a fear that the components and the combination parts are separated from each other. Of course, the inner structure of the housing 400, 800 is to be in close contact with the end of the assembly, but the effect was not sufficiently exhibited due to the short coupling length in the housing.

In addition, adhesion between the heat rod assembly 100, the heat fin assembly 200, the (−) terminal 300, and the frames 600 and 900 arranged side by side may result in an air gap or the like. In this case, the overall performance of the preheater is also reduced.

The present invention was devised to solve the above problems, and the object of the present invention is to strengthen the coupling structure between the housing and the end of the assembly, thereby preventing the separation between parts and improving the preheater's original performance by improving the contact ability. It is to provide a vehicle preheater with a solid assembly structure that can maintain the.

In order to achieve the above object, a preheater for a vehicle having a rigid assembly structure according to the present invention,
