The present invention relates to a heat fin assembly of a vehicle preheater and a vehicle preheater, and more particularly, to a vehicle preheater including a PTC element and a heat fin assembly included in the vehicle preheater.

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

Such a heating device has a long time until the cooling water is heated and the room is heated since the cooling water flowing around the engine flows into the heater after the engine is started. As a result, after starting, there has been a disadvantage of being in a cold state for a certain time.

In order to solve such a problem, in recent years, a vehicle preheater using a PTC element has been developed, and a representative configuration thereof is shown in FIGS. 1 and 2.

As shown in the drawing, a conventional vehicle preheater 1000 includes a heat rod assembly 100 including a PTC element and a heat fin assembly 200 arranged side by side on both sides of the heat rod assembly 100. (+) Terminal 130 derived from the heat rod assembly 100, (-) terminal 300 arranged side by side with the heat fin assembly 200, the heat rod assembly 100 and the heat fin Frames (200) and (900) respectively coupled to both side ends of the assembly of the assembly (200) and (-) terminal (300); Housing 400 for coupling the combination of the heat rod assembly 100, heat fin assembly 200, (-) terminal 300, and the frame 600, 900 at both ends (종단 部) It comprises 800.

The heat rod assembly 100 has various structures disclosed in many publications, including Korean Patent Publication No. 0496598 (Applicant: Woori Industry).

The heat fin assembly 200 is coupled to the frame 600 via a pin protector 700 formed of a plate made of SUS material.

At this time, as shown in FIG. 3, the heat fin assembly 200 has a configuration in which a corrugate type heat fin 210 is fixedly coupled to the pin plate 220 in the longitudinal direction. The heat fins 210 and the fin plates 220 are made of a light material having a high heat transfer rate such as aluminum.

However, since the heat fin assembly 200 of the conventional vehicle preheater 1000 has a single structure of the heat fin 210 and the fin plate 220, the quantity of a single product becomes excessive and it is difficult to manage accordingly. There was this. Moreover, there was a disadvantage that the working process is increased and the production time and labor cost are increased.

Another conventional heat fin assembly for solving this problem and the structure of a vehicle preheater including the same is disclosed in Korean Patent Publication No. 4,595,9 (Worri Industry), and with reference to FIGS. 4 to 6. It will be described below.

As shown, a conventional vehicle preheater includes a conductive heat rod assembly 2100, a conductive heat fin assembly 2200, a (-) terminal 2300, a pin protector 2700 and a frame 2600. ) 2900 are arranged side by side, and the housings 2400 and 2800 are configured to fix both ends thereof together.

The heat rod assembly 100 is a component including a heat rod (not shown) for coupling a PTC device (not shown), the (+) terminal 2130 is derived from the end. In general, such a heat rod assembly 100 is disclosed in various publications in many publications, including Korean Patent Publication No. 0496598 (Applicant: Woori Industry).

In addition, heat fin assemblies 2200 are arranged side by side on the heat rod assembly 2100.

In addition, (-) terminal 2300 is disposed side by side of the heat fin assembly 2200.

Meanwhile, when the frames 2600 and 2900 are coupled to both side ends of the combination of the heat rod assembly 2100, the heat fin assembly 2200, and the (−) terminal 2300, the more rigid coupling is performed. This can be done.

In addition, when at least one of the two frames 2600 and 2900 is coupled to the heat fin assembly 2200 via the pin protector 2700, the heat fin may be prevented from being deformed by the lateral load. .

In this case, at least one set of the heat fin assemblies has a configuration in which two heat fin assemblies 2250 are in contact with each other with a support plate 2230 interposed therebetween.

Specifically, the heat fin assembly 2250 has a structure in which corrugated heat fins 2210 are coupled side by side in the longitudinal direction of the conductive fin plate 2220, and the fin plate 2220 and the support plate are parallel to each other. The heat fin 2210 is arranged in contact with each other between the 2230.

In addition, both ends of the two pin plates 2220 and the support plate 2230 disposed therebetween are fixedly coupled to each other. It is coupled by rivets 3100.

However, in such a conventional vehicle preheater, the negative terminal 300 is disposed separately in parallel with the heat fin assembly 200.

Therefore, when the vehicle preheater is deformed, the negative terminal 300 and the heat fin assembly 200 may be partially spaced apart from each other, which may significantly reduce the performance.

In addition, since the heat fin assembly 200 and the (-) terminal 300 in the conventional vehicle preheater 1000 have to be prepared separately, there is still a disadvantage in that there are many assembly processes and manufacturing time and labor cost are high.

In addition, the quantity of a la carte is still excessive, so management has remained difficult.

The present invention has been made to solve the above problems, an object of the invention is to prevent the separation between the (-) terminal and the heat fin assembly even when the pre-heater itself is deformed vehicle pre-heater that can maintain a predetermined performance And a heat fin assembly of a vehicle preheater.

In addition, an object of the present invention is to combine the (-) terminal and the heat fin assembly in one part in advance, the heat fin assembly of the vehicle pre-heater and vehicle pre-heater that can reduce the actual preheater assembly process and manufacturing time To provide.

In addition, an object of the present invention is to provide a heat pre-heater assembly of a vehicle pre-heater and a vehicle pre-heater that can be easily maintained by reducing the number of parts by combining the (-) terminal and the heat fin assembly into one part in advance. It is.
