Abstract
Description
Technical Field
[0001] This utility model belongs to the field of control module technology, specifically relating to a power control module. Background Technology
[0002] The dense distributed fiber optic multi-channel power control module is used in dense distributed supporting high-power generation channel control and channel expansion modules. It requires the use of a dense distributed fiber optic demodulator and a dense distributed fiber optic power generator to automatically switch multiple expansion components, so as to realize the remote and timed opening and closing of the dense distributed heating optical cable.
[0003] Generally, a fanless cooling structure is used, such as a heat sink with fins, to keep the power control module in a relatively sealed state, thereby improving the overall dust protection of the device. This cooling structure requires external airflow for better heat dissipation. However, the power control module is usually placed in one location with a small gap between its lower surface and the mounting surface. This gap cannot be adjusted according to the installation environment, resulting in high temperatures at the lower surface of the power control module that are difficult to dissipate. Consequently, the electronic components inside the power control module experience high temperatures, affecting its lifespan.

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0032] like Figures 1-10 As shown, a power control module in one embodiment of this utility model includes a power control module body 1. Four first slots 11 are provided at the four corners of the power control module body 1. Height adjustment components 2 are connected to the opposite surfaces of the first slots 11 via shafts. The first slots 11 can completely accommodate the height adjustment components 2. That is, when the height adjustment components 2 are not in use, they do not occupy space. Figure 9 As shown, the height adjustment component 2 can change the height of the power control module body 1, increase the distance between the lower end face of the power control module body 1 and the placement surface, increase the heat dissipation space of the lower end face of the power control module body 1, increase the space for air flow, thereby improving the heat dissipation effect of the power control module body 1.
[0033] Specifically, such as Figures 1-6 As shown, the height adjustment assembly 2 includes a first connecting rod 21, a rotating block 22, and a second connecting rod 24. The rotating block 22 is connected to the first slot 11 via a shaft. The first connecting rod 21 and the rotating block 22 are fixedly connected. The first connecting rod 21 is a cylindrical body, while the second connecting rod 24 is slidably connected inside the first connecting rod 21. That is, by sliding the second connecting rod 24 within the first connecting rod 21, the overall length of the height adjustment assembly 2 can be changed. The longer the height adjustment assembly 2 is, the greater the distance between the lower end face of the power control module body 1 and the placement surface, which increases the space for airflow and facilitates heat dissipation of the power control module body 1.
[0034] like Figures 1-6As shown, a locking ring 23 is threaded to the end of the first connecting rod 21 away from the rotating block 22. When the locking ring 23 is tightened, it can apply pressure to the end of the first connecting rod 21 away from the rotating block 22, making the diameter of this end smaller. The smaller diameter increases the friction with the second connecting rod 24, thereby locking the second connecting rod 24.
[0035] like Figure 6 As shown, a second threaded post 242 is fixedly connected to the end of the second connecting rod 24 away from the rotating block 22. A foot pad 3 is threaded onto the second threaded post 242. The foot pad 3 increases the contact area between the height adjustment component 2 and the placement surface, making the power control module body 1 more stable. The foot pad 3 includes a connecting part 31 and a contact part 32, which are rotatably connected. The connecting part 31 has a threaded hole 311 that matches the second threaded post 242, and the threaded hole 311 is threadedly connected to the second threaded post 242. The contact part 32 contacts the placement surface and is a rubber pad to increase the friction with the placement surface. When the heights of the two height adjustment components 2 at the front end and the two height adjustment components 2 at the rear end are different, the contact part 32 and the connecting part 31 can rotate, ensuring that the contact part 32 is stably placed on the placement surface.
[0036] like Figures 1-2 As shown, when the height adjustment component 2 is housed in the first slot 11, the end of the rotating block 22 near the placement surface is fixedly connected to the first threaded post 221. The first threaded post 221 and the second threaded post 242 have the same specifications, and the connecting part 31 can also be threadedly connected to the first threaded post 221. When the connecting part 31 and the first threaded post 221 are threadedly connected, the height of the power control module body 1 from the placement surface is the initial height.
[0037] like Figure 2 As shown, a second slot 12 matching the first threaded post 221 is provided on the side wall of the first slot 11. When the height adjustment component 2 is perpendicular to one side of the power control module body 1, the first threaded post 221 can be stored in the second slot 12.
[0038] The rotating block 22 is made of rubber, meaning it is a rubber rotating block. The rotating block 22 has an interference fit with the bottom wall of the first slot 11. A certain amount of force is required to rotate the rotating block 22. This is to minimize the possibility of the rotating block 22 wobbling and affecting the stability of the power control module body 1.
[0039] As a further improvement of this utility model, the rotating block 22 includes a hollow rod 211, which has a hollow portion filled with coolant 212. The hollow rod 211 contacts the lower end face of the power control module body 1, enabling heat exchange between the coolant 212 and the lower end face of the power control module body 1. The coolant 212 dissipates heat from the lower end face of the power control module body 1. Figure 7 As shown, when the lower end face of the power control module body 1 is close to the placement surface, the height adjustment component 2 is housed in the first slot 11, and the heat dissipation effect of the power control module body 1 is increased through the first connecting rod 21.
[0040] Preferably, the outer diameter of the first connecting rod 21 is larger than the outer diameter of the first slot 11. That is, a part of the first connecting rod 21 is located outside the first slot 11. The first connecting rod 21 located outside the first slot 11 can exchange heat with the air, so that the first connecting rod 21 can also be cooled.
[0041] As a further improvement to this utility model, such as Figure 4 , Figure 7 , Figure 8 As shown, the interior of the second connecting rod 24 is filled with paraffin wax 241, and the power control module body 1 has a third slot 13 that matches the second connecting rod 24. The second connecting rod 24 can be locked into the third slot 13. When the temperature of the power control module body 1 becomes too hot, such as... Figure 7 As shown, especially when the distance between the power control module body 1 and the placement surface is too small and heat dissipation is not easy, the power control module body 1 is more likely to overheat. The paraffin 241 inside the second connecting rod 24 can absorb heat, thereby reducing the temperature of the power control module body 1.
[0042] The outer diameter of the third slot 13 is smaller than the outer diameter of the second connecting rod 24. That is, a part of the third slot 13 is located outside the second connecting rod 24, which can dissipate heat from the outside and cool the paraffin 241.
[0043] This invention, by incorporating a height adjustment component 2, can alter the gap between the power control module body 1 and the placement surface. The larger gap provides greater airflow space, facilitating heat dissipation for the power control module body 1. The first connecting rod 21 and coolant 212 allow for simple heat dissipation of the height adjustment component 2 even with an initial gap between the power control module body 1 and the placement surface. Furthermore, by having a second connecting rod 24 engage with the third slot 13, heat can be absorbed through the second threaded post 242 when the power control module body 1 overheats, thereby reducing its temperature.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
