DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Radiator fan structure of the present invention, that is, the radiator fan 100 is centrifugal to the suction force in the front and rear direction through the blade 111 by forming the centrifugal impeller portion 120 on the side of the rotating shaft 110 in which the blade 111 is formed. By further including the suction force in the lateral and centrifugal direction through the impeller portion 120 is a technology that can further increase the heat dissipation in the system for dissipating the LED headlamp using the rotational force of the radiator.

Meanwhile, in the following description of the present invention, the same reference numerals are used for the same or similar components as those described above in the related art, and redundant descriptions are omitted.

As shown in FIG. 3, the LED headlamp heat dissipation structure of the present invention includes LED headlamps 10 'provided at both sides of the front face of the vehicle, a radiator 50 provided at the front center of the vehicle, and the radiator. Radiator fan 100 is installed on the rear of the 50, and the LED headlamp 10 'and the connection pipe 200 for connecting the radiator fan 100.

That is, the LED headlamp heat dissipation structure of the present invention discharges the air in the connection pipe 200 by the suction force generated when the radiator fan 100 rotates, and the LED headlamp (a) due to the pressure difference due to the air discharge in the connection pipe 200. 10 ') discharges the high heat generated in the LED module (not shown) to the outside through the connection pipe (200).

The LED headlamp 10 ′ includes a housing, an LED module installed at one side of the housing, and a heat dissipation fin provided at a bottom of the LED module.

Meanwhile, in order to increase the air suction force in the LED headlamp heat dissipation structure, a centrifugal impeller is further formed on the radiator fan 100.

As shown in FIG. 4, the centrifugal impeller radiator fan 100 has a rotation shaft 110 in which a plurality of blades 111 are formed, and is formed in a shape surrounding the plurality of blades 111 and has an outer circumferential surface. Accordingly, the centrifugal impeller is provided to include an impeller 120 that sucks air outside the radiator fan 100 while the centrifugal impeller rotates when the rotary shaft 110 rotates.

Here, the impeller 120 has a front and rear connection rings 121 and 122 formed in a ring shape at the front and rear ends of the plurality of wings 111, respectively, and the front and rear connection rings 121 ( 122 includes an impeller 123 provided between. And the impeller 123 is provided to be inclined in the direction of rotation between the front and rear connection rings 121, 122.

That is, the impeller 120 rotates in conjunction with the rotation of the rotating shaft 110, at this time by the rotation of the impeller 123 to suck the air in the outer portion into the inner portion, according to the discharge portion of the connection pipe 200 The air in 220 can be sucked more quickly.

The connector 200 is connected to the inlet 210 through a housing 10 ′ in which the LED module of the LED headlamp is built, and the discharge part 220 is the centrifugal impeller 123 of the impeller 120. Is provided close to, the discharge portion 220 has a larger diameter than the inlet portion (210). As shown in FIG. 5, the discharge part 220 extends long along the impeller 123, and the suction force generated through the impeller 123 extends to the inlet 210 of the connection pipe 200. It can be delivered effectively.

Referring to the state of use of the LED headlamp heat dissipation structure including the radiator fan 100 of the present invention having the configuration as described above are as follows.

At the same time as the LED module of the LED headlamp emits light, a high temperature is generated, and this high temperature raises the temperature inside the housing of the LED headlamp 10 'through the cooling fan.

On the other hand, the radiator fan 100 installed in the radiator rotates at the time of starting the car, at this time sucks air in the front and rear direction by the rotation of the blade 111 of the rotary shaft 110, while being provided on the side of the rotary shaft 110 The air near the side is sucked inward by the rotation of the centrifugal impeller 120. As described above, as shown in FIG. 5, as the suction force by the rotation of the blade 111 and the impeller portion 120 of the rotating shaft 110, the air inside the connecting pipe 200 is discharged to the outside of the connecting pipe ( Due to the pressure difference inside the housing of the 200 and the LED headlamp 10 ′, hot air inside the housing may be quickly discharged to the outside through the connection pipe 200.

In addition, by further forming the centrifugal impeller portion 120 on the side of the radiator fan 100 to generate the suction force in the lateral direction and centrifugal direction it is possible to discharge the high temperature heat source generated in the LED headlamp more quickly. .
