Description

A kind of radiator of LED automobile headlamp

Technical field

The utility model relates to LED technical field of heat dissipation, specially a kind of radiator of LED automobile headlamp.

Background technique

LED (Light Emitting Diode, light emitting diode), is the semiconductor optoelectronic that can convert electrical current into luminous energy Device belongs to one kind of optoelectronic semiconductor.As the environmental protection concept of energy-saving and emission-reduction is gradually rooted in the hearts of the people, present headlight for vehicles LED component is gradually adopted, it is generally known that, high-power LED device will generate a large amount of heat, and hot-fluid during the work time Density is very high, if these heats cannot be transmitted and be dissipated in time, it will rise rapidly the temperature of chip, heat is caused to be answered Power is unevenly distributed uniform chip luminous efficiency reduction etc., influences the headlight for vehicles even service life of vehicle.

Utility model content

The shortcomings that in order to overcome the prior art to refer to, the utility model provide a kind of LED automobile headlamp of good heat dissipation effect Radiator.

The utility model solves the used technical solution of its technical problem are as follows: a kind of radiator of LED automobile headlamp, including Pedestal, preceding cooling fin and rear cooling fin, the preceding cooling fin and rear cooling fin are in the form of annular discs, and the pedestal both ends are separately connected The center point of the preceding cooling fin and rear cooling fin is also equipped with several circular radiatings between the preceding cooling fin and rear cooling fin Piece is equipped between the adjacent annular fin, between the annular fin and the preceding cooling fin and rear cooling fin Heat dissipation gap；The preceding cooling fin, rear cooling fin and all circular radiating on pieces offer communicate it is circumferentially uniformly distributed Several heat release holes.

The pedestal, preceding cooling fin, rear cooling fin and the annular fin are all made of aluminum metal or copper made of metal At.

The heat dissipation gap is in be evenly arranged.

The edge of the annular fin is uniformly provided with several flutings, increase the heat dissipation area at annular fin edge and And save raw material.

The outer diameter of the annular fin is greater than the outer diameter of the preceding cooling fin and rear cooling fin.The annular fin With centre, to the preceding cooling fin and rear cooling fin both ends, parabolically downward trend is distributed outer diameter.

The beneficial effects of the utility model are: this heat spreader structures is simple, and it is convenient for production and low in cost, due to automobile Headlight is horizontally mounted, the perpendicular arrangement in the gap between cooling fin, and according to hot-air gravity principle, hot-air can Xiang Shangliu Dynamic, cold air flows downward, and the hot-air on such annular fin side can be flowed up along heat dissipation gap, and cold air is downward Flowing can thus form cross-ventilation to which effectively heat source be gone out, the lateral hollow out opened up on cooling fin Heat release hole help quickly radiate.

Specific embodiment

The utility model is further detailed with reference to the accompanying drawing.

As shown in Figure 1 to Figure 3, a kind of radiator of LED automobile headlamp, including pedestal 1, preceding cooling fin 2 and rear cooling fin 3, for connecting LED component, the preceding cooling fin 2 and rear cooling fin 3 are in the form of annular discs and vertical for preceding cooling fin 2 or rear cooling fin 3 Straight arrangement, the pedestal 1 is horizontally disposed and both ends are separately connected the center point of the preceding cooling fin 2 and rear cooling fin 3, before described Several vertically arranged annular fins 4, the adjacent annular fin 4 are also equipped between cooling fin 2 and rear cooling fin 3 Between, heat dissipation gap, the heat dissipation gap are equipped between the annular fin 4 and the preceding cooling fin 2 and rear cooling fin 3 It is arranged in equal equation；Offered in the preceding cooling fin 2, rear cooling fin 3 and all annular fins 4 communicate in circle Several heat release holes 31 of Zhou Junbu.

The pedestal 1, preceding cooling fin 2, rear cooling fin 3 and the annular fin 4 are all made of aluminum metal or copper gold Category is made.

The edge of the annular fin 4 is uniformly provided with several flutings 41, increases the radiating surface at annular fin edge Product and saving raw material.

The outer diameter of the annular fin 4 is greater than the outer diameter of the preceding cooling fin 2 and rear cooling fin 3.The circular radiating The outer diameter of piece 4, to the preceding cooling fin 2 and the parabolically downward trend distribution of 3 both ends of rear cooling fin, is conducive to level with centre The heat dissipation in direction.

As shown in figure 4, headlight for vehicles 5 is horizontally mounted, cooling fin annular gap is in upright position, according to hot-air Gravity principle, hot-air can flow up, and cold air flows downward, and the hot-air on such annular fin side can be along annular Gap flows up, and cold air flows downward, and can thus form cross-ventilation to which effectively heat source be gone out.

As described above, the only preferred embodiment of the utility model is real when that cannot limit the utility model with this The range applied, i.e., generally according to simple equivalence changes made by present utility model application the scope of the patents and utility model description with Modification all still belongs in the range of the utility model patent covers.
