[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Reference below Figure 1 A heat sink 100 according to an embodiment of the first aspect of the present invention is described.

[0026] like Figure 1 As shown, the heat sink 100 according to the first embodiment of the utility model includes: a substrate 10, a heat pipe 20 and a plurality of heat sinks 30. For example, the number of the heat sinks 30 may be two, three, eight, ten, twenty or twenty-five.

[0027] Specifically, the heat pipe 20 is connected to the substrate 10 and extends along the thickness direction of the substrate 10. A plurality of heat sinks 30 are fixed on the heat pipe 20. The plurality of heat sinks 30 are arranged at intervals along the length direction of the heat pipe 20. The surfaces on both sides of the heat sink 30 in the thickness direction are non-planar.

[0028] During the operation of the headlight assembly, part of the heat generated by the headlight can be transferred to the substrate 10, the heat pipe 20 absorbs heat from the substrate 10 and transfers part of the heat to the multiple heat sinks 30, the substrate 10, the heat pipe 20 and the multiple heat sinks 30 are in contact with the air to transfer the heat to the air, thereby achieving the heat dissipation of the headlight by the radiator 100.

[0029] It can be understood that, in the process of the radiator 100 dissipating heat for the vehicle lamp, the larger the area of ​​the radiator 100 in contact with the air, the higher the heat exchange efficiency between the radiator 100 and the air.

[0030] In this embodiment, by providing a plurality of heat sinks 30, each heat sink 30 can be in contact with the air to dissipate heat. In this way, the contact area between the heat sink 100 and the air can be increased, thereby improving the heat dissipation efficiency of the heat sink 100 for the vehicle lamp. By setting the two side surfaces of the heat sink 30 in the thickness direction to be non-planar, the contact area between the heat sink 30 and the air can be increased, thereby further improving the heat dissipation efficiency of the heat sink 100 for the vehicle lamp.

[0031] During the product design process, the number of heat sinks 30 in the radiator 100, the thickness of the heat sink 30, the spacing between the heat sinks 30, or the shape of the two side surfaces of the heat sink 30 in the thickness direction can be adjusted, so that the radiator 100 can meet the heat dissipation requirements of more models of vehicle lamp assemblies and reduce the difficulty of product design.

[0032] According to the radiator 100 of the first aspect of the present invention, by setting the two side surfaces of the heat sink 30 in the thickness direction to be non-planar, the heat dissipation area of ​​the radiator 100 can be increased, thereby improving the heat dissipation efficiency of the radiator 100 for the vehicle lamp, thereby improving the reliability of the vehicle lamp assembly during operation.

[0033] In some embodiments of the present invention, Figure 1 As shown, one or more convex parts 31 protruding along the thickness direction of the heat sink 30 are formed on the heat sink 30. For example, the convex parts 31 may be one, two, three or five. When the number of the convex parts 31 is multiple, the multiple convex parts 31 are arranged in a plane perpendicular to the thickness direction of the heat sink 30. In this way, the surfaces of both sides of the heat sink 30 in the thickness direction can be non-planar. In the process of product design, the number of convex parts 31 can be adjusted, so that the heat dissipation area of ​​the heat sink 100 meets more product design needs and reduces the difficulty of product design.

[0034] In some embodiments of the present invention, Figure 1 As shown, a plurality of protrusions 31 are arranged along a first direction (eg Figure 1 ) and extends in a second direction (e.g. Figure 1 The convex portions 31 are arranged in sequence in the left-right direction (shown in the figure), and the first direction is perpendicular to the second direction. Thus, the uniformity of the distribution of the convex portions 31 on the heat sink 30 can be improved, thereby improving the uniformity of the heat dissipation of the heat sink 30, and further improving the uniformity of the heat dissipation of the heat sink 100 to the headlight. In particular, the plurality of convex portions 31 can extend along the edge of the heat sink 30 in the first direction, and the plurality of convex portions 31 can also penetrate the heat sink 30 in the first direction.

[0035] In some embodiments of the utility model, in the second direction, the convex portion 31 may extend along an arc, along a fold line, or along at least one line segment and at least one arc segment. In the process of product design, the shape of the convex portion 31 extending in the second direction may be adjusted so that the heat sink 30 can fit into more assembly space, reducing the difficulty of product design.

[0036] In some embodiments of the present invention, Figure 1As shown, the plurality of protrusions 31 include a first protrusion 311 and a second protrusion 312. The protrusion directions of the first protrusion 311 and the second protrusion 312 in the thickness direction of the heat sink 30 are opposite. In the second direction, the first protrusion 311 and the second protrusion 312 are arranged alternately. As a result, the contact area between the heat sink 30 and the air on both sides in the thickness direction is large, and the protrusions 31 on both sides in the thickness direction of the heat sink 30 are evenly distributed, so that the heat dissipation efficiency and uniformity of the heat dissipation of the radiator 100 to the vehicle lamp can be further improved.

[0037] In some embodiments of the present invention, Figure 1 As shown, a through hole 32 is formed on the heat sink 30, and the heat sink 30 is sleeved on the heat pipe 20 through the through hole 32 and fixedly connected to the heat pipe 20. In this way, the heat sink 30 can absorb the heat on the heat pipe 20 in the circumference of the heat pipe 20 in the radial direction, thereby improving the heat transfer efficiency between the heat pipe 20 and the heat sink 30, and the heat transfer between the heat pipe 20 and the heat sink 30 is more uniform, thereby further improving the heat dissipation efficiency and uniformity of the heat sink 100 for the vehicle lamp.

[0038] In some embodiments of the present invention, Figure 1 As shown, a plurality of through holes 32 arranged at intervals are formed on the heat sink 30, and the number of the heat pipes 20 is multiple, for example, the number of the heat pipes 20 may be two, three or four, and the multiple heat pipes 20 are arranged at intervals, and the heat sink 30 is sleeved on the multiple heat pipes 20 through the multiple through holes 32. Thus, each heat pipe 20 can absorb heat from the substrate 10 and transfer the heat to the heat sink 30 and the air, and at the same time, the multiple heat pipes 20 can absorb heat from different positions on the substrate 10, thereby further improving the heat dissipation efficiency and uniformity of the heat sink 100 for the vehicle lamp.

[0039] In some embodiments of the present invention, Figure 1As shown, the heat pipe 20 includes: a bending section 21 and a straight section 22, one end of the bending section 21 is connected to the substrate 10, the other end of the bending section 21 is away from the substrate 10 in the thickness direction of the substrate 10 and extends obliquely toward the center of the heat sink 30, the straight section 22 is connected to the other end of the bending section 21 and extends in a straight line in the thickness direction of the substrate 10, and multiple heat sinks 30 are sleeved on the straight section 22. In this way, the space between the bending sections 21 of the multiple heat pipes 20 can be made larger. It can be understood that the heat on the heat pipe 20 is transferred from the bending section 21 to the straight section 22, and the temperature of the bending section 21 will be higher. Therefore, the heat dissipation requirements of the bending section 21 are higher. The larger space between the bending sections 21 of the multiple heat pipes 20 can make more air between the multiple bending sections 21 absorb heat, and the air flows more smoothly between the multiple bending sections 21, thereby improving the heat exchange efficiency between the bending section 21 and the air, and further improving the heat dissipation efficiency of the radiator 100 for the headlights.

[0040] During the product design process, the shape of the bending segment 21 or the sizes of the bending segment 21 and the straight segment 22 can be adjusted to meet more product design requirements and reduce the difficulty of product design.

[0041] In some embodiments of the utility model, the heat pipe 20 is a heat pipe having an evaporation part and a condensation part, the evaporation part is connected to the substrate 10, and the plurality of heat sinks 30 are connected to the condensation part. It can be understood by those skilled in the art that the heat exchange medium in the heat pipe exchanges heat through phase change, and the efficiency of heat exchange is higher, so that the heat dissipation efficiency of the radiator 100 to the headlight can be further improved. During the operation of the headlight assembly, the heat generated by the headlight is transferred to the substrate 10, the evaporation part absorbs the heat on the substrate 10 and transfers it to the condensation part, and the condensation part transfers the heat to the plurality of heat sinks 30. At the same time, the heat pipe 20, the substrate 10 and the heat sink 30 exchange heat with the air, thereby achieving the heat dissipation of the headlight by the radiator 100.

[0042] The vehicle lamp assembly according to the second embodiment of the present invention comprises: the heat sink 100 and the vehicle lamp according to the first embodiment of the present invention, wherein the vehicle lamp is arranged on the substrate 10 and is located on the side of the substrate 10 away from the heat pipe 20 and the heat sink 30 .
