These modules can flexibly adjust the lighting angle and mode according to different driving scenarios and needs, providing drivers with a better and safer lighting experience. However, due to the extremely complex requirements of their optical structure, the layout of internal optical components and the light propagation path require the heat sink to have a matching complex shape, and simple heat sinks such as cold forging, aluminum extrusion, bending, and riveting cannot be used directly. Currently, only die-cast aluminum heat sink solutions can be used, but die-cast aluminum heat sinks have low thermal conductivity. To achieve sufficient heat dissipation, the size of the heat sink needs to be increased, which significantly increases the weight of the heat sink and adversely affects the overall design and performance of the vehicle headlights.

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] The following is for reference. Figures 1-6 A heat sink assembly 10 according to an embodiment of the present application is described. The heat sink assembly 10 includes a heat sink housing 11 and heat sink fins 12.

[0024] A first mounting surface 111 is formed on one side of the radiator housing 11 along the length direction of the vehicle. The first mounting surface 111 is suitable for mounting a lighting module. A second mounting surface 112 is formed on the other side of the radiator housing 11 along the length direction. There are multiple heat sinks 12, which are spaced apart at the second mounting surface 112 along the width direction of the vehicle.

[0025] Currently, due to the extremely complex optical structure requirements of lighting modules, the internal optical component layout and light propagation path necessitate that the heat sink possess a complex shape to match them. Simple heat sinks made through cold forging, aluminum extrusion, bending, or riveting cannot be used directly. Currently, only die-cast aluminum heat sinks are available. However, die-cast aluminum heat sinks have low thermal conductivity. To achieve sufficient heat dissipation, the size of the heat sink needs to be increased, significantly increasing its weight and negatively impacting the overall design and performance of the vehicle lights.

[0026] In response, this application provides a radiator assembly 10 that can improve heat dissipation efficiency, reduce overall weight and volume, and meet the overall design and performance requirements of vehicle lights.

[0027] Specifically, the radiator assembly 10 may include a radiator housing 11 and a heat sink 12. A first mounting surface 111 may be formed on the other side of the radiator housing 11 along the length of the vehicle. The first mounting surface 111 may be used to mount a lighting module. In some embodiments, the lighting module has a lamp panel, which may be mounted on the first mounting surface 111. Optionally, the lamp panel and the first mounting surface 111 may be detachably connected by screws or bolts, or the lamp panel and the first mounting surface 111 may be detachably connected by snap-fit ​​or plug-in. For example, screw holes may be formed on the first mounting surface 111, and screw holes may also be formed on the lamp panel. The screw holes on the first mounting surface 111 may correspond to the screw holes on the lamp panel. The lamp panel may be mounted on the first mounting surface 111 by passing screws or bolts through the two screw holes.

[0028] Furthermore, a second mounting surface 112 can be formed on the other side of the radiator housing 11 along the length direction. The number of heat sinks 12 can be multiple, and multiple heat sinks 12 can be installed on the second mounting surface 112. It should be noted that the heat sinks 12 can be aluminum sheets, and multiple heat sinks 12 can be installed at intervals along the width direction of the vehicle on the second mounting surface 112. The heat sinks 12 can be fixed by welding or riveting. Compared with the die casting method used in the prior art, the overall weight and volume can be reduced. This can meet the assembly and manufacturing of lighting modules for multi-angle lamp panels, and the use of aluminum heat sinks 12 with better thermal conductivity can improve heat dissipation efficiency, thereby reducing the overall weight and volume.

[0029] In short, the radiator assembly 10 of this application embodiment has a radiator housing 11 and heat sinks 12. The radiator housing 11 has a first mounting surface 111 and a second mounting surface 112 formed on both sides along the length direction. The first mounting surface 111 is used to mount the lighting module. The number of heat sinks 12 can be multiple. Multiple heat sinks 12 can be installed at intervals along the width direction on the second mounting surface 112. Compared with the prior art, using multiple heat sinks 12 to install on the radiator housing 11 can improve heat dissipation efficiency, reduce overall weight and volume, and meet the overall design and performance requirements of the vehicle light.

[0030] like Figure 2As shown, in some embodiments of this application, the heat sink 12 may include a first heat dissipation part 121 and a second heat dissipation part 122. The first heat dissipation part 121 may extend along the width direction and may be connected to the second mounting surface 112. Optionally, the first heat dissipation part 121 and the second mounting surface 112 may be fixed by riveting or contact surface welding. The second heat dissipation part 122 may be disposed on both sides of the first heat dissipation part 121 along the width direction and may extend in a direction away from the second mounting surface 112. The second heat dissipation part 122 and the first heat dissipation part 121 may be integrally formed. The first heat dissipation part 121 may be connected to the second mounting surface 112 to transfer the heat of the heat sink housing 11 to the first heat dissipation part 121, and the first heat dissipation part 121 may then transfer the heat to the second heat dissipation part 122, thereby completing the heat dissipation function.

[0031] like Figures 2 to 4 As shown, in some embodiments of this application, the second mounting surface 112 may have a first mounting portion 1121, and the side of the first heat dissipation portion 121 facing the second mounting surface 112 may have a second mounting portion 1211. The second mounting portion 1211 may be correspondingly provided with the first mounting portion 1121, and the second mounting portion 1211 may be connected with the first mounting portion 1121, thereby fixing the first heat dissipation portion 121 to the second mounting surface 112. In some embodiments, the first mounting portion 1121 may be constructed as one of a riveting post and a riveting hole, and the second mounting portion 1211 may be constructed as the other of a riveting post and a riveting hole. The riveting post may pass through the riveting hole, and the riveting post and the riveting hole may be fixed by riveting, thereby completing the installation of the first heat dissipation portion 121. In other embodiments, the first heat dissipation portion 121 and the second mounting surface 112 may be fixed by screws or bolts, or the first heat dissipation portion 121 and the second mounting surface 112 may be directly welded together by contact surfaces.

[0032] Furthermore, there can be multiple first mounting parts 1121, which can be spaced out at the second mounting surface 112. Similarly, there can be multiple second mounting parts 1211, which can be arranged one-to-one with the multiple first mounting parts 1121. By providing multiple first mounting parts 1121 and multiple second mounting parts 1211, the connection strength between the first heat dissipation part 121 and the second mounting surface 112 can be improved.

[0033] like Figure 5As shown, in some embodiments of this application, the heat sink 12 may further include a third heat dissipation part 123. The third heat dissipation part 123 may be connected to the free ends of two second heat dissipation parts 122 that are close to each other in two adjacent heat sinks 12 along the width direction. It is understood that each of the two adjacent heat sinks 12 along the width direction has two heat dissipation parts. The two heat dissipation parts on the side of the two heat sinks 12 that are close to each other can be connected by the third heat dissipation part 123, so that the multiple heat sinks 12 are constructed into an integral structure, so as to facilitate the welding of the heat sinks 12 to the second mounting surface 112, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0034] In some embodiments of this application, the thickness of the second heat dissipation part 122 along the width direction is T, satisfying the relationship 0.3mm≤T≤0.7mm. That is, the thickness of the second heat dissipation part 122 along the width direction can be any value between 0.3mm and 0.7mm. For example, the thickness of the second heat dissipation part 122 along the width direction can be, but is not limited to, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, etc. If the thickness of the second heat dissipation part 122 along the width direction is too large, it will occupy a larger volume. If the thickness of the second heat dissipation part 122 along the width direction is too small, it will result in low strength. Therefore, setting the thickness of the second heat dissipation part 122 along the width direction within the above range can reduce the module volume and weight and improve the heat conduction effect.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments of this application, the second mounting surface 112 may have a bolt mounting portion 1122, and the first heat dissipation portion 121 or the second heat dissipation portion 122 may have a clearance hole 124 suitable for avoiding the bolt mounting portion 1122. Alternatively, both the first heat dissipation portion 121 and the second heat dissipation portion 122 may have clearance holes 124 for avoiding the bolt mounting portion 1122. By providing clearance holes 124, interference between the first heat dissipation portion 121 or the second heat dissipation portion 122 and the bolt mounting portion 1122 can be avoided, so as to facilitate the installation and fixation of the heat sink 12.

[0036] like Figure 3 and Figure 6As shown, in some embodiments of this application, the heat sink housing 11 may include a first housing 113 and a second housing 114, which are connected in sequence. The first housing 113 and the second housing 114 are used to fix the lamp board of the lighting module. The first housing 113 may have a first sub-mounting surface 1131, and the second housing 114 may have a second sub-mounting surface 1141. The first sub-mounting surface 1131 and the second sub-mounting surface 1141 constitute a second mounting surface 112. Multiple heat sinks 12 constitute two sets of heat dissipation fins. Each set of heat dissipation fins is respectively mounted on the first sub-mounting surface 1131 and the second mounting surface 1141. This satisfies the assembly and manufacturing of multi-angle lamp board modules and allows the use of aluminum heat dissipation fins with better thermal conductivity to improve heat dissipation efficiency, ultimately reducing the weight and size of the product.
