AI Technical Summary
During the heat dissipation process, the existing fine-eye car light radiators have been blocked due to the radiator fins, which leads to the convection of heat and the heat dissipation efficiency is not high.
A thin-eye headlight radiator is designed to reduce convection obstacles by forming an accessible heat flow area between the bottom plate and the side plate of the radiator, and adopt a thermal arc and a release groove structure to improve heat dissipation efficiency.
By reducing the obstacles to heat convection, the heat dissipation efficiency is improved, and the entire radiator weight is greatly reduced by using the AL1070 material.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of headlight radiators, in particular to a fine-eye headlight radiator. Background Art
[0002] At present, in order to be more dazzling, the headlights of cars in the automotive market adopt a fine-eye design. LED lamp beads are installed in the fine-eye headlights. A large amount of heat will be generated when the LED lamp beads are working. As Figure 4 shown, the existing fine-eye headlight radiator includes a heat dissipation bottom plate. Heat dissipation fins are connected to the side surface of the heat dissipation bottom plate. There are gaps between the heat dissipation fins. The radiator is made of ADC12 material by die casting, and the overall weight is 580g - 600g. When the headlight is working, the heat generated on the heat dissipation bottom plate moves to the side and then rises through the heat dissipation fins. Although there are heat dissipation gaps between the heat dissipation fins, when the heat on the heat dissipation bottom plate undergoes heat convection to the side, it will still be hindered by the heat dissipation fins. As Figure 5 shown, when the heat encounters the heat dissipation fins, most of the heat passes through the gaps of the heat dissipation fins and is dissipated by the heat dissipation fins, while a part of the heat will be hindered after encountering the heat dissipation fins and form a vortex under the heat dissipation bottom plate. Therefore, there is still room for improvement in the radiator with this kind of structure. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a fine-eye headlight radiator aiming at the above-mentioned deficiencies of the prior art. To solve the above technical problem, the technical scheme adopted by the utility model is:
[0004] A fine-eye headlight radiator includes a radiator bottom plate. First heat dissipation fins are evenly distributed on the bottom surface of the radiator bottom plate. A radiator side plate is bent on the side surface of the radiator bottom plate. A heat conduction arc is formed at the bending part of the radiator side plate and the radiator bottom plate. Second heat dissipation fins are evenly distributed on the outer side surface of the radiator side plate. An unobstructed heat flow area is formed between the second heat dissipation fins and the first heat dissipation fins.
[0005] Further, release grooves are arranged at intervals at the heat conduction arc.
[0006] Further, the gap between the first heat dissipation fins is 5 - 7mm.
[0007] Further, the gap between the second heat dissipation fins is 5 - 7mm, and the height of the second heat dissipation fins is 40 - 70mm.
[0008] Further, the thickness of the first heat dissipation fins and the second heat dissipation fins is 0.9 - 1.1mm.
[0009] Further, the radiator is made of AL1070 material.
[0010] Compared with the prior art, an improved radiator for a narrow-eye headlight of the present utility model is provided. By improving the existing radiator, an unobstructed heat flow area is set between the bottom heat sink and the side heat sink, reducing the convection resistance and improving the heat dissipation efficiency. The radiator is made of AL1070 material, significantly reducing the weight of the entire radiator. Description of the Drawings

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
[0018] As shown in Figure 1 and Figure 2 A narrow-eye headlight radiator includes a radiator bottom plate 1. The bottom surface of the radiator bottom plate 1 is evenly distributed with first heat sinks 2. The side surface of the radiator bottom plate 1 is bent to form a radiator side plate 3. The bent part of the radiator side plate 3 and the radiator bottom plate 1 forms a heat conduction arc 4. Release grooves 5 are arranged at intervals at the heat conduction arc 4. The outer side surface of the radiator side plate 3 is evenly distributed with second heat sinks 6. An unobstructed heat flow area 7 is formed between the second heat sinks 6 and the first heat sinks 2. Through the unobstructed heat flow area 7, the resistance during heat convection is reduced.
[0019] In this embodiment, the first heat sinks 2 are arranged within the area covered by the radiator bottom plate, and the second heat sinks 6 are arranged within the area covered by the radiator side plate. There are blank spaces at the position of the heat conduction arc for the first heat sinks 2 and the second heat sinks 6. This blank space is the heat flow area 7. The heat conduction arc 4 formed by bending guides the heat convected by the radiator bottom plate 1.
[0020] As shown in Figure 3As shown in the figure, when the radiator dissipates heat, the heat of the first heat sink 2 on the radiator base plate 1 flows to both sides. Since the radiator is a heat flow area 7 without obstacles and no vortex effect will be generated, the heat dissipation efficiency is improved. Among them, most of the heat is conducted through the heat-conducting arc 4 and dissipated by the second heat sink 6, and a small part of the heat is dissipated through the release groove 5. At the same time, the release groove 5 is beneficial to releasing stress and facilitating bending.
[0021] In this embodiment, the spacing between the first heat sinks and the gap between the second heat sinks are 5 - 7 mm. When the gap between the heat sinks is less than 5 mm, their arrangement is too dense, the convection effect is reduced, heat is concentrated and difficult to dissipate. When the gap between the heat sinks is greater than 7 mm, the heat sinks are too sparse and the heat dissipation effect is reduced. The height of the second heat sink is 40 - 70 mm. Among them, when the height of the heat sink is less than 40 mm, the heat dissipation effect is not good. When the height of the heat sink exceeds 70 mm, the heat dissipation effect is relatively stable. At this time, increasing the height of the heat sink will cause the weight of the radiator to increase.
[0022] In this embodiment, the radiator is made of AL1070 material and is formed by forging and bending. The thickness of the first heat sink and the second heat sink is 0.9 - 1.1 mm.
[0023] The comparison between the radiator with this structure and the original radiator is as follows in the table:
[0024]
[0025]
[0026] It can be seen that the radiator adopting the structure of the present utility model is light in weight and has improved heat dissipation efficiency.
[0027] The present utility model is not limited to the described embodiments. Those skilled in the art can still make some modifications or changes without departing from the spirit of the present utility model and within the scope of disclosure. Therefore, the scope of the protection of the rights of the present utility model shall be subject to the scope defined by the claims.
