Description

LED headlight radiator section bar for automobile

Technical Field

The utility model relates to a LED headlight radiator section bar for car.

Background

At present more and more cars begin to use the LED lamp as the light, compare common halogen lamp and xenon lamp, energy-concerving and environment-protective, light quality is better, and the spotlight nature is stronger, and the blind area is little, and night and heavy fog weather use also can have fine discernment degree, also can not influence the field of vision to the driver of coming because of the light is more dispersed during the meeting, and the energy band comes splendid driving experience to feel. The use of LED lamps as vehicle lamps is inherently favorable, but also faces heat dissipation challenges. The LED element is sensitive to temperature change, and the LED lamp is continuously lightened at high temperature, so that the power is easily reduced, the substrate is yellow, the lamp beads fall off and the like, the service life of light is further influenced, and the loss is caused when the lighting effect of the light for a long time for the car lamp is deteriorated because the light is in a high-temperature state for a long time. Therefore, the heat dissipation design of the LED must be considered from the chip to the whole heat sink in every step. However, the existing heat radiator has poor heat radiation effect, and needs to be improved urgently. When the number of the heat dissipation fins is large, the distance between the roots of the heat dissipation fins is too small, and the heat dissipation efficiency of the heat sink is affected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a LED headlight radiator section bar for car, the radiating effect is good, can not appear the interval undersize of heat radiation fin root through the thickness that reduces heat radiation fin lower extreme and influence the radiating condition of radiator, and the heat radiation effect is good, and the radiating efficiency is high to this kind of mode is little to extrusion die's requirement, and extrusion die makes more easily when reducing the raw materials quantity.

In order to achieve the above object, the technical solution of the present invention is to design a car-use LED headlight radiator profile, including plate-shaped body and the heat radiation fins integrated with the plate-shaped body, the junction of the heat radiation fins and the plate-shaped body is formed by transition connection of smooth curves, and the thickness of the end of the heat radiation fins close to the plate-shaped body is smaller than the thickness of the heat radiation fins away from one end of the plate-shaped body. The bottom ends of the radiating fins are arranged into the concave curved surfaces, so that the distance between the roots of the adjacent radiating fins cannot be too small when the quantity of the radiating fins is large, the problem that the heat radiation effect is influenced due to the fact that the distance between the roots of the radiating fins is too small is solved, the concave curved surfaces are compared with the roots of the original plane radiating fins, the radiator section bars with the same size and specification are provided with the concave curved surfaces after extrusion forming, the consumption of raw materials can be saved, and the concave curved surfaces have larger surface areas than the plane, and the radiating effect is further improved. And the concave curved surface is arranged, compared with the design of surface tooth form (or wavy lines to obtain larger surface area), the die for hot extrusion is easy to manufacture, and the design of the profile structure enables the die for extrusion to be easier to manufacture, which is another benefit brought by the structure.

The further technical scheme is that the radiator profile further comprises a folded plate structure connected with the mounting plate, the folded plate structure comprises at least one extending plate integrally formed with the plate-shaped body and a folded plate integrally formed with the extending plate, and the folded plate and the extending plate form a mounting clamping groove.

The further technical proposal is that the part of the folded plate, which is back to the mounting clamping groove, is provided with a weight-reducing heat dissipation groove. Compared with the prior folded plate structure with the installation clamping grooves, the weight-reducing radiating grooves are further formed in the back face of the folded plate, so that the using amount of aluminum alloy for extrusion can be reduced, the surface area of the whole radiator profile can be increased, and the radiating effect is improved while the using amount of raw materials is reduced.

The further technical scheme is that the plate-shaped body is rectangular flat, one end, far away from the plate-shaped body, of each radiating fin is rectangular plate-shaped, and the part, close to the plate-shaped body, of each radiating fin comprises a pair of concave curved surfaces.

The further technical proposal is that the weight-reducing radiating grooves are rectangular grooves or spiral grooves.

The utility model has the advantages and the beneficial effects that: the heat radiation effect is good, the situation that the heat radiation of the radiator is influenced due to the fact that the distance between the roots of the heat radiation fins is too small can not occur by reducing the thickness of the lower ends of the heat radiation fins, the heat radiation effect is good, the heat radiation efficiency is high, the requirement on the extrusion die is low, and the extrusion die is easier to manufacture while the consumption of raw materials is reduced; the bottom ends of the radiating fins are arranged into the concave curved surfaces, so that the distance between the roots of the adjacent radiating fins cannot be too small when the quantity of the radiating fins is large, the problem that the heat radiation effect is influenced due to the fact that the distance between the roots of the radiating fins is too small is solved, the concave curved surfaces are compared with the roots of the original plane radiating fins, the radiator section bars with the same size and specification are provided with the concave curved surfaces after extrusion forming, the consumption of raw materials can be saved, and the concave curved surfaces have larger surface areas than the plane, and the radiating effect is further improved. And the concave curved surface is arranged, compared with the design of surface tooth form (or wavy lines to obtain larger surface area), the die for hot extrusion is easy to manufacture, and the design of the profile structure enables the die for extrusion to be easier to manufacture, which is another benefit brought by the structure. Compared with the prior folded plate structure with the installation clamping grooves, the weight-reducing radiating grooves are further formed in the back face of the folded plate, so that the using amount of aluminum alloy for extrusion can be reduced, the surface area of the whole radiator profile can be increased, and the radiating effect is improved while the using amount of raw materials is reduced.
