[0038] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only partial structures related to the present invention are shown in the accompanying drawings, rather than the entire structure.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the connection of the internal structures of two elements or the interaction relationship between two elements.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figure 1 As shown, this embodiment provides a heat pipe side splicing heat conduction radiator, the radiator includes a mounting frame 100, the mounting frame 100 is used to set the heat-generating parts such as lamps, heat-generating electronic components. Optionally, the mounting frame 100 can be made of a material with high thermal conductivity to quickly absorb the heat generated by the conductive heat-generating parts.

[0043] For example, please refer to Figure 1 and Figure 2 In this embodiment, the mounting frame 100 includes a frame body 110 and a plurality of uniform temperature heat pipes 120. Among them, a mounting groove is provided on the frame body 110, and a plurality of uniform temperature heat pipes 120 are arranged in parallel in the mounting groove, so as to further improve the thermal conductivity efficiency of the mounting frame 100 by utilizing the heat absorption and heat conduction effect of the uniform temperature heat pipes 120. Specifically, the sides of the plurality of uniform temperature heat pipes 120 can be arranged in contact with each other to ensure that heat conduction can be carried out between two adjacent uniform temperature heat pipes 120, so that the heat in different areas of the mounting frame 100 is kept uniform. In addition, the cross-sectional shape of the uniform temperature heat pipe 120 is directional, which can not only increase the contact area between two adjacent uniform temperature heat pipes 120, but also make the contact surface and the surface away from the heat pipe 120 and the heating element both planes, thereby improving the thermal conductivity.

[0044] Further, the radiator further comprises a plurality of heat pipe assemblies 200, which are sequentially arranged along the X direction (first direction), and the heat pipe assemblies 200 comprise a first heat pipe 210 and a second heat pipe 220, wherein the first heat pipe 210 comprises a first heat absorbing portion 211, a connecting portion 212 and a first heat conducting portion 213, wherein the first heat absorbing portion 211 abuts against the mounting frame 100, one end of the connecting portion 212 is connected to one end of the first heat absorbing portion 211, and in a direction away from the first heat absorbing portion 211, the connecting portion 212 and the first heat conducting portion 213 are sequentially connected, the first heat conducting portion 213 and the second heat pipe 220 extend along the Z direction (second direction), and the second heat pipe 220 and the first heat conducting portion 213 are arranged one-to-one in correspondence. The plurality of heat pipe assemblies 200 absorb heat from the mounting frame 100 by using the first heat absorbing portion 211 of the first heat pipe 210, and conduct the heat to the far end by using the first heat conducting portion 213. When the heat conduction distance is too large, due to the influence of the processing technology of the heat pipe assembly 200, the end of the first heat conducting part 213 away from the first heat absorbing part 211 will have a certain distance and poor heat conduction effect, or even fail to conduct heat, thereby affecting the heat conduction distance and heat conduction effect of the first heat pipe 210. The second heat pipe 220 can effectively make up for the poor heat conduction effect area of ​​the first heat conducting part 213, thereby realizing long-distance heat conduction and improving the heat conduction efficiency of the heat pipe assembly 200.

[0045] However, in the prior art, the first heat conducting part 213 and the second heat pipe 220 are usually abutted against each other at the end faces, with a small contact area. In addition, due to the influence of the processing technology of the first heat pipe 210, the heat conduction effect of the end of the first heat conducting part 213 is poor, and the thermal conductivity between the first heat conducting part 213 and the second heat pipe 220 is relatively small.

[0046] In order to solve the above problems, Figure 2 As shown, in this embodiment, the second heat pipe 220 and the first heat conducting part 213 are partially spliced ​​on the side perpendicular to the X direction, thereby increasing the contact area between the second heat pipe 220 and the first heat conducting part 213, improving the heat conduction effect from the first heat conducting part 213 to the second heat pipe 220, and further improving the heat dissipation power of the radiator.

[0047] like Figure 1 and Figure 2 As shown, the heat sink further includes a first heat dissipation module 300, and the first heat dissipation module 300 includes a plurality of heat dissipation components 310. The plurality of heat dissipation components 310 are arranged in parallel along the X direction, and the heat dissipation components 310 are provided with a stepped placement groove 311 extending along the Z direction, and the placement groove 311 is used to accommodate the first heat conducting portion 213 and the second heat pipe 220, so that the first heat pipe 210 and the second heat pipe 220 are in contact with the side wall of the placement groove 311, so as to achieve heat conduction between the heat pipe assembly 200 and the heat dissipation component 310, and utilize the heat dissipation component 310 to quickly dissipate heat.

[0048] like Figure 1-Figure 3 As shown, there are multiple first heat pipes 210 and multiple second heat pipes 220, and the first heat absorbing parts 211 of the multiple first heat pipes 210 are arranged in parallel and in contact along the X direction. The multiple first heat pipes 210 and the second heat pipes 220 are used to increase the thermal conductivity of the heat pipe assembly 200, and the first heat absorbing parts 211 of the multiple first heat pipes 210 can increase the contact area between the first heat pipe 210 and the mounting frame 100, thereby increasing the heat absorption rate and thermal conductivity of the first heat absorbing parts 211, which is beneficial to improving the heat dissipation power of the radiator. At the same time, the contact arrangement of the multiple first heat absorbing parts 211 is beneficial to the mutual heat conduction between the first heat absorbing parts 211, thereby improving the temperature uniformity effect of different areas of the radiator.

[0049] Optionally, the cross-sectional shape of the first heat absorption part 211 is a direction, which is beneficial to increase the contact area between two adjacent first heat absorption parts 211 and the contact area between the first heat absorption part 211 and the mounting frame 100, thereby improving the thermal conductivity efficiency of the first heat absorption part 211.

[0050] For the overall structure of the first heat pipe 210, the first heat pipe 210 can be a U-shaped structure. At this time, the first heat pipe 210 includes two connecting parts 212 and two first heat conducting parts 213, and the two first connecting parts 212 and the two first heat conducting parts 213 are respectively located at the two ends of the first heat absorbing part 211. Thereby increasing the heat conduction area of ​​the first heat pipe 210, it is beneficial to improve the heat dissipation effect of the radiator. Of course, in other embodiments, the first heat pipe 210 can also be an L-shaped structure. At this time, the first heat pipe 210 includes a connecting part 212 and a first heat conducting part 213 sequentially arranged at one end of the first heat absorbing part 211.

[0051] It is understandable that no matter the first heat pipe 210 is a U-shaped structure or an L-shaped structure, the heat on the side of the first heat absorption part 211 of the first heat pipe 210 away from the connection part 212 cannot be conducted to the far end, and the heat is relatively concentrated.

[0052] In order to solve the above problem, as an optional solution, the heat pipe assembly 200 further includes a plurality of third heat pipes 230, which are arranged in parallel along the Y direction (third direction), and the third heat pipe 230 includes a second heat absorbing portion 231 and a second heat conducting portion 232 connected to each other in an L shape, and the second heat absorbing portion 231 abuts against the end surface of the first heat absorbing portion 211 away from the mounting frame 100. The third heat pipe 230 can effectively absorb and conduct heat to the side of the first heat absorbing portion 211, avoid heat concentration, and help improve the heat dissipation effect of the radiator.

[0053] Optionally, the cross-sectional shape of the third heat pipe 230 is square to increase the contact area between adjacent third heat pipes 230, between the third heat pipe 230 and the first heat absorption part 211, and between the third heat pipe 230 and the heat dissipation assembly 310, thereby improving the heat dissipation power of the radiator.

[0054] Specifically, when two adjacent third heat pipes 230 are arranged at intervals, along the X direction, the third heat pipes 230 of each two adjacent groups of heat pipe assemblies 200 are arranged opposite to each other, and the sides of the second heat absorption parts 231 of the two oppositely arranged groups of third heat pipes 230 are arranged in parallel and in contact with each other, thereby increasing the contact area of ​​the two adjacent third heat pipes 230, which is conducive to mutual heat conduction between adjacent third heat pipes 230, so as to improve the temperature uniformity effect at different positions of the heat pipe assembly 200. At the same time, while ensuring the same heat absorption area, it is conducive to reducing the number of each group of third heat pipes 230 arranged opposite to each other, which is conducive to reducing costs.

[0055] In other embodiments, when two adjacent third heat pipes 230 are arranged in contact with each other, along the X direction, the third heat pipes 230 of each two adjacent groups of heat pipe assemblies 200 are arranged opposite to each other, and the end surfaces of the second heat absorption parts 231 of the two oppositely arranged groups of third heat pipes 230 are arranged in contact with each other, thereby achieving mutual heat conduction between the two oppositely arranged groups of third heat pipes 230.

[0056] Furthermore, the heat pipe assembly 200 also includes a fourth heat pipe 240 , which is disposed in one-to-one correspondence with the second heat conducting portion 232 , and the fourth heat pipe 240 is in contact with a portion of the second heat conducting portion 232 , thereby extending the heat conduction distance of the third heat pipe 230 .

[0057] In addition, similar to the process of the first heat pipe 210, the far end of the third heat pipe 230 also has a poor local heat conduction effect, or even a failure of heat conduction, thereby affecting the heat conduction distance and heat conduction effect of the first heat pipe 210. Therefore, in this embodiment, the fourth heat pipe 240 is partially spliced ​​with the side surface of the second heat conducting part 232 perpendicular to the X direction to increase the contact area between the fourth heat pipe 240 and the second heat conducting part 232, so as to avoid the fourth heat pipe 240 improving the heat conduction and heat dissipation effect of the heat pipe assembly 200.

[0058] Now combined Figure 1 , Figure 2 and Figure 4 The detailed structure of the heat dissipation component 310 is described.

[0059] like Figure 1 , Figure 2 and Figure 4As shown, the heat dissipation assembly 310 includes a second heat dissipation member 313 and a first heat dissipation member 312. The first heat dissipation member 312 is sequentially arranged along the Z direction, so that the first heat dissipation member 312 and the second heat dissipation member 313 can both dissipate heat in stages and contact with the heat pipe assembly 200 at the same time, thereby realizing long-distance heat transmission and improving the heat dissipation power of the radiator.

[0060] At the same time, there are two first heat sinks 312, so as to improve the flexibility of the heat sink structure and facilitate the selection and setting of the number of first heat sinks 312 according to the heat of the heating element.

[0061] The first heat sink 312 is formed by stacking and riveting. At this time, the first heat sink 312 is in contact with the part of the heat pipe assembly 200 that can conduct heat normally, so as to dissipate heat for the heat pipe assembly 200. At this time, the wall thickness of the first heat sink 312 can be less than 0.4 mm, which is conducive to achieving the lightweight of the heat sink assembly 310 and reducing the overall weight of the heat sink mechanism with graded heat conduction. Specifically, the first heat sink 312 includes a stacked and riveted structure of multiple layers of heat sinks 2121. Each layer of heat sink 2121 is formed by stamping fins, and then multiple heat sinks 2121 are riveted together in multiple layers. The molding efficiency is high, and the first heat sink assembly 310 formed in this way can be directly processed into a mounting groove 311 structure.

[0062] Furthermore, the two first heat sinks 312 are formed by the same mold. When assembled, the two first heat sinks 312 are rotated 180 degrees relative to each other, and the placement grooves 311 on the two first heat sinks 312 are correspondingly arranged, thereby reducing the processing cost. Exemplarily, due to the partial contact between the side of the first heat pipe 210 and the second heat pipe 220, and the partial contact between the side of the third heat pipe 230 and the fourth heat pipe 240, the depth of the placement groove 311 of the local structure of the first heat sink 312 disposed near the mounting frame 100 near the mounting frame 100 is used to accommodate the thickness of one first heat pipe 210 or one third heat pipe 230, and the placement groove 311 of the local structure of the first heat sink 312 away from the mounting frame 100 is used to accommodate the thickness of one first heat pipe 210 and one second heat pipe 220 or one third heat pipe 230 and one fourth heat pipe 240, so the depth of the placement groove 311 at this position is larger. The placement groove 311 on the first heat sink 312 disposed away from the mounting frame 100 is used to accommodate the thickness of one second heat pipe 220 or one fourth heat pipe 240 .

[0063] The depth of the placement groove 311 for accommodating the thickness of a first heat pipe 210 and a second heat pipe 220 or the thickness of a third heat pipe 230 and a fourth heat pipe 240 is the first depth, and the depth of the placement groove 311 for accommodating the thickness of a first heat pipe 210 or a third heat pipe 230 or the depth of the placement groove 311 for accommodating the thickness of a second heat pipe 220 or a fourth heat pipe 240 is the second depth. In this embodiment, the first heat pipe 210, the second heat pipe 220, the third heat pipe 230, and the fourth heat pipe 240 have the same thickness. Therefore, the two first depths are the same, and the first depth is twice the second depth.

[0064] Since the first heat sink 312 is riveted, when a mold is used to process the first heat sink 312, a plug-in is provided on the mold. When processing the first heat sink 312 disposed near the mounting frame 100, the plug-in can be retracted for processing for a distance to form a mounting groove 311 of a first depth, and then extended for processing for a distance to form a mounting groove of a second depth, and a step is formed at the depth change to complete the processing of the first heat sink 312. Or the above two parts can be processed in the opposite order. When processing the first heat sink 312 disposed away from the mounting frame 100, the plug-in is directly used to process and form the mounting groove 311 of the first depth. During assembly, one of the two first heat sinks 312 processed by the same set of molds can be rotated 180°, so that the mounting groove 311 with a depth of the first depth can be located on both sides of the mounting groove 311 with a depth of the second depth, thereby forming a stepped mounting groove 311 structure.

[0065] The second heat sink 313 is arranged at one end of the two first heat sinks 312 away from the mounting frame 100, and the second heat sink 313 is extruded. The second heat sink 313 is extruded into a continuous type, and the thermal conductivity of the material of the second heat sink 313 itself is utilized to perform secondary heat conduction and heat dissipation at the non-heat-conducting position at the far end of the heat pipe assembly 200, thereby realizing graded heat conduction of the first heat sink 312 and the second heat sink 313, making full use of the entire heat dissipation area of ​​the heat pipe assembly 200, which is beneficial to improving the heat dissipation power of the radiator.

[0066] The second heat sinks 313 of two adjacent groups of heat sink components 310 are in contact with the side surfaces of the second heat pipes 220 to increase the contact area between the second heat sinks 313 and the second heat pipes 220 and improve the heat dissipation effect.

[0067] See also Figure 1 and Figure 2The heat sink further includes a second heat sink module 400, and the second heat sink module 400 is attached to the side of the mounting frame 100 away from the heat pipe assembly 200, and there is no need to set up a structure for heat conduction through a U-shaped heat pipe in the prior art, which simplifies the heat sink structure, makes heat conduction more direct and reduces thermal resistance. Furthermore, the second heat sink module 400 is a profile, which is conducive to further improving the heat conduction effect.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the utility model.
