The top of the heat dissipation base has a rotating cavity, and the rotating disk rotates within the rotating cavity via a rotating assembly at its bottom center. A rotating groove is formed on the heat dissipation base, and a limiting heat conduction component corresponding to the rotating groove is connected to the bottom of the rotating disk. This application solves the problem of deformation caused by the rotating tray's vibration and bumps when the entire device is mounted on a vehicle by setting a rotatable rotating disk on top of the heat dissipation base, with the heat source mounted on the rotating disk.

Description

Technical Field

[0001] This utility model relates to the field of antenna heat source heat conduction technology, specifically to an axial limiting heat conduction mechanism. Background Technology

[0002] In the field of antennas, the transmitting components, i.e., radio frequency components, as well as several tools for receiving and transmitting signals are generally mounted on a metal plate. However, the problem of needing to dissipate heat from multiple heat sources simultaneously is frequently encountered. During the operation of these electronic products, heat is inevitably generated, causing the temperature of the internal components to rise. In particular, certain local component concentration areas may generate high temperatures, which not only damages their own performance but also reduces the performance reliability of the entire system, and may even lead to system failure. Furthermore, when the entire device is mounted on a vehicle for transportation, the metal plate will shake when the vehicle moves on bumpy roads, thus affecting the stability of the metal plate.

[0003] Therefore, how to concentrate and dissipate heat from the heat source and how to ensure the stability of the entire device during transportation are urgent problems to be solved in the antenna field. Utility Model Content

[0008] As a further embodiment of this utility model: the rotating assembly includes an upper drive wheel installed at the middle position of the bottom of the rotating disk, and an outer drive wheel installed at the middle position of the top of the heat dissipation base, wherein the outer side of the upper drive wheel is movably connected to the outer drive wheel through a bearing.

[0010] As a further embodiment of this utility model: the limiting heat-conducting component is located directly below the heat source mounting groove, and a heat-conducting pad is provided between the heat source mounting groove and the limiting heat-conducting component.

[0014] As a further embodiment of this utility model: the limiting heat-conducting component has an "I" shaped structure, and the cross-section of the rotating groove has an inverted "T" shaped structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Reference Figure 1 and Figure 2 An axial limiting heat conduction mechanism includes a heat dissipation base 1 and a rotating disk 2, wherein the rotating disk 2 is installed on the heat dissipation base 1 and can rotate inside the heat dissipation base 1. The top of the rotating disk 2 is provided with several heat source mounting slots 23, and heat sources 3 are installed in the heat source mounting slots 23.

[0030] It should be noted that, for ease of understanding and description, the vertical positions in this application are indicated by... Figure 1 For example, the other directions can be deduced from this. It should be understood that this direction setting is only for the convenience of description and understanding, and should not be construed as a limitation on this application.

[0031] Reference Figure 5 The heat dissipation base 1 is made of aluminum. The heat dissipation base 1 has a disc-shaped structure. A circular and recessed rotating cavity 11 is opened on the top. An outer drive wheel 12 is set at the middle of the top of the rotating cavity 11. An annular rotating groove 14 is opened on the top of the rotating cavity 11 and outside the outer drive wheel 12. When the rotating disk 2 rotates, it can play a limiting role.

[0032] The limiting heat-conducting component 12 is made of copper and graphite, which has good heat conduction effect.

[0033] Furthermore, the cross-sectional projection shape of the rotating groove 14 is an inverted "T" shape, which serves to limit the heat-conducting component 12, allowing it to rotate within the rotating groove 14, but making it difficult for it to detach from the rotating groove 14.

[0034] Furthermore, the inner surface of the rotating groove 14 is coated with thermal grease, and the limiting thermal conductive element 12 can contact the thermal grease. The thermal grease is used to increase the heat conduction effect, thereby enabling the heat of the limiting thermal conductive element 12 to be discharged from the rotating groove 14.

[0035] Reference Figure 3 and Figure 4 The rotating disk 2 is made of aluminum. Several heat source mounting slots 23 are provided on the top of the rotating disk 2. The heat source mounting slots 23 are arranged in a ring array above the rotating slot 14.

[0036] Furthermore, the limiting heat-conducting component 12 is located below the heat source 3, and a heat-conducting pad is added between the heat source 3 and the limiting heat-conducting component 12 to ensure sufficient contact between the contact surfaces of the heat source 3 and the limiting heat-conducting component 12, thereby preventing gaps between the heat source 3 and the limiting heat-conducting component 12 due to processing reasons, which would affect the heat conduction efficiency.

[0037] Furthermore, the limiting heat-conducting component 12 has an overall "I" shape structure, with its top fixed inside the rotating disk 2 and its bottom installed inside the "T"-shaped rotating groove 14. The bottom of the limiting heat-conducting component 12 can rotate inside the rotating groove 14.

[0038] Reference Figure 3 and Figure 4 An upper drive wheel 22 is provided at the bottom center of the rotating disk 2. The outer diameter of the upper drive wheel 22 is smaller than the inner diameter of the outer drive wheel 12. The upper drive wheel 22 and the outer drive wheel 12 are connected by a bearing 13, so that the rotating disk 2 can rotate relative to the heat dissipation base 1. When rotating, the limiting heat conduction component 12 can rotate inside the rotating groove 14.

[0039] The specific operating principle of this application is as follows:

[0040] During operation, the rotating disk 2 rotates. When the entire mechanism is subjected to vibration, the limiting heat-conducting component 21 will limit the up-and-down vibration of the edge of the rotating disk 2, ensuring the flatness of the rotating disk 2 and preventing it from tilting or deforming.

[0041] When the heat source 3 generates heat, the heat will be transferred from the heat source 3 to the limiting heat conductor 21 through the heat conduction pad. The limiting heat conductor 21 will transfer the heat to the heat dissipation base 1, and the heat will be dissipated through the contact between the heat dissipation base 1 and the outside world.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
