Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the field of optical communication, optical modules, as core components for photoelectric signal conversion, directly affect the reliability of the entire communication system. With the increase in data transmission rates and the growing trend towards miniaturization, the power density of optical modules has increased significantly, leading to a sharp rise in heat generated during operation. If heat dissipation is not timely, the high-temperature environment will accelerate device aging and may even cause signal distortion or hardware damage. Therefore, heat dissipation design has become a key technical aspect in the research and development of optical module components, and the industry has developed various heat dissipation solutions to meet the needs of different application scenarios.

[0030] Traditional optical module heat dissipation structures mostly employ passive cooling methods, such as placing metal heat sinks on the surface of the optical module body. These heat sinks are typically made of aluminum or copper alloys, increasing surface area for contact with air and utilizing natural convection to transfer heat to the surrounding environment. Regarding structural fixation, early designs often used screws to directly fasten the heat sinks to the optical module housing. While this method ensures a tight contact, the installation process requires precise alignment of the threaded holes, and maintenance requires specialized tools for disassembly, resulting in low operational efficiency. Furthermore, long-term thermal expansion and contraction can cause a decrease in screw preload, creating tiny gaps at the contact surface and actually reducing thermal conductivity. Some improved designs attempted to use elastic clips instead of screws, achieving quick installation and removal of the heat sinks through the elastic deformation of the plastic clips. However, plastic materials are prone to creep at high temperatures, and their elasticity decays rapidly, often leading to loosening of the clips after a period of use, making it difficult to maintain stable contact pressure.

[0031] In high-density applications such as data centers, optical modules need to be closely arranged with multiple ports on the switch panel, which places higher demands on the spatial layout of the heat dissipation structure. To address this, the industry has developed integrated thermal pads, filling the space between the optical module and the heat sink with flexible thermally conductive material. This material is typically composed of a silicone matrix mixed with metal oxide particles, which can both fill surface micro-irregularities and establish a continuous heat conduction path. However, the long-term stability of thermal pads is challenging; under high-temperature environments, the silicone component may gradually harden or even crack, leading to increased contact thermal resistance. Some high-end devices have attempted to introduce heat pipe technology, embedding the evaporation section inside the optical module to rapidly dissipate heat using the circulation of a phase-change working fluid. However, heat pipes require precision-machined sealed cavities, resulting in high production costs, and are sensitive to installation angles, limiting their application in general-purpose scenarios.

[0032] To address the heat dissipation requirements of pluggable optical modules, modular heat dissipation component designs have emerged in recent years. Typical structures include guide rail systems with spring-loaded tabs, such as metal tabs on both sides of the optical module, using spring force to press a heat-conducting plate firmly against the surface of the heat-generating elements. This design allows the module to automatically adjust contact pressure during insertion and removal without additional fixing operations. However, in practical use, it has been found that metal springs are prone to stress relaxation under long-term compression, especially when the optical module's operating temperature reaches above 60°C. The elastic modulus of the spring material decreases with increasing temperature, further exacerbating pressure attenuation. Some manufacturers have attempted to use shape memory alloys or special coatings, but this significantly increases material costs, and the matching of temperature response characteristics with the optical module's thermal cycling cycle still needs optimization.

[0033] Another type of innovative solution focuses on the active adjustment capability of the heat dissipation structure, such as integrating miniature temperature sensors and motorized actuators into the heat dissipation components. When the temperature exceeds a set threshold, the drive mechanism automatically increases the contact pressure between the heat-conducting plate and the optical module; conversely, it decreases the pressure to reduce mechanical wear. This type of intelligent heat dissipation system demonstrates good temperature control in laboratory tests, but the complex electromechanical structure significantly increases the component size, contradicting the trend towards miniaturization of optical modules. Furthermore, the additional electronic control unit requires independent power, making wiring difficult in confined spaces and posing a risk of electromagnetic interference.

[0034] In the field of materials science, the development of novel thermally conductive materials has provided new ideas for heat dissipation design. For example, graphene films, due to their ultra-high in-plane thermal conductivity, have been attempted for use in optical module heat dissipation, achieving rapid lateral heat diffusion by attaching the film to the surface of the optical module. However, due to the large interfacial thermal resistance between graphene and the metal shell, the actual improvement in heat dissipation effect is limited. Nanomaterial composites enhance longitudinal thermal conductivity by controlling the microstructure of the material, but face challenges in process consistency during large-scale production. In addition, phase change energy storage materials have been introduced as buffer layers to absorb excess heat at temperature peaks, but the volume changes during the phase change process may affect structural stability.

[0035] From an application scenario perspective, optical modules in outdoor communication equipment need to withstand more stringent environmental conditions. For example, optical module components in 5G base stations need to operate stably within a temperature range of -40℃ to 85℃. Traditional rubber seals are prone to aging and failure under thermal cycling, allowing dust or moisture to intrude and affect the heat dissipation interface. Some solutions use an all-metal sealing structure, but this significantly increases weight, and the difference in thermal expansion coefficients of different metal materials may cause structural deformation. Optical modules in industrial automation scenarios also need to consider vibration factors. Conventional spring-compression structures may resonate under continuous mechanical vibration, causing periodic fluctuations in contact pressure and affecting heat dissipation stability.

[0036] Maintainability of heat dissipation components is also a crucial consideration in existing technologies. Some designs employ a magnetic fixing structure, using permanent magnets to attach the heat-conducting plate to the surface of the optical module. While this method facilitates quick replacement, the strong magnetic field may interfere with the internal circuitry of the optical module, particularly high-speed signal transmission lines which are susceptible to electromagnetic interference. Another modular design uses a sliding rail with a locking mechanism, allowing maintenance personnel to replace heat dissipation components without disassembling the entire unit. However, the multi-level locking mechanism requires extremely high machining precision; improper tolerances can lead to uneven contact pressure distribution and difficulty in eliminating localized hot spots.

[0037] Regarding structural innovation, one patent proposes integrating the heat dissipation fins with the optical module housing, forming a three-dimensional heat dissipation channel through die casting. This integrated design reduces interfacial thermal resistance, but the mold development cost is high and it is not conducive to later maintenance. Another solution involves placing a miniature turbine fan inside the optical module to force airflow through the heat dissipation channel. While this significantly improves heat dissipation efficiency, the noise generated by the fan operation does not meet the requirements of some quiet scenarios, and there is a risk of mechanical failure of moving parts.

[0038] Please see Figure 1-3As shown, this embodiment provides an optical module assembly, including: an optical module body 1, two U-shaped fixing seats 2 are mounted on the upper side of the optical module body 1, and two clamping plates 12 are slidably engaged. The two U-shaped fixing seats 2 are located between the two clamping plates 12, and a heat-conducting plate 16 is clamped between the two clamping plates 12. The heat-conducting plate 16 is located between the two U-shaped fixing seats 2.

[0039] A rotating rod 18 is rotatably fitted inside the U-shaped fixing seat 2. An L-shaped rod 3 is installed around the rotating rod 18. One end of the L-shaped rod 3 is rotatably fitted between the two sides of the inner wall of the U-shaped fixing seat 2. A first push-pull rod 4 is rotatably fitted at the lower part of the L-shaped rod 3, and a second push-pull rod 5 is rotatably fitted at the upper part. The rotating rod 18 is located between the first push-pull rod 4 and the second push-pull rod 5. Two push-pull blocks 10 are installed on the opposite inner sides of the two clamping plates 12. The first push-pull rod 4 and the second push-pull rod 5 are rotatably connected to the corresponding push-pull blocks 10 respectively. The first push-pull rod 4 and the second push-pull rod 5 are located between the corresponding two push-pull blocks 10.

[0040] One application of this embodiment is as follows: When replacing and installing the heat-conducting plate 16, firstly, the optical module body 1 inside the photodetector is removed, and then the L-shaped rod 3 is rotated, causing the rotating rod 18 to rotate accordingly. This allows the L-shaped rod 3 to rotate around the axis of the rotating rod 18, and the first push-pull rod 4 and the second push-pull rod 5 push the push-pull block 10 away from the U-shaped fixing seat 2, thereby applying a pushing force to the clamping plate 12. This causes the two clamping plates 12 to slide synchronously in opposite directions along the surface of the optical module body 1. When the two clamping plates 12 have moved to a specified distance, the clamping of the heat-conducting plate 16 is released, the heat-conducting plate 16 is removed, and a new heat-conducting plate 16 is placed in. Similarly, referring to the above operation, the L-shaped rod 3 is rotated in the opposite direction, and the first push-pull rod 4 and the second push-pull rod 5 are used to pull the push-pull block 10, causing the two clamping plates 12 to slide synchronously towards each other along the surface of the optical module body 1, so that the two clamping plates 12 form a clamping force on the heat-conducting plate 16, thereby completing the replacement and installation of the heat-conducting plate 16. It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0041] By rotating the L-shaped rod 3, the first push-pull rod 4 and the second push-pull rod 5 can be used to pull the two clamping plates 12 to clamp the heat-conducting plate 16 synchronously. The mechanical transmission replaces the elastic element, which reduces the probability of clamping force decay due to material fatigue, improves the stability of the clamping plates 12 in clamping and fixing the heat-conducting plate 16 for a long time, and ensures that the heat-conducting plate 16 can dissipate heat stably, thereby improving the overall heat dissipation performance of the optical module assembly. The rotating rod 18 provides stable rotation support for the L-shaped rod 3, ensuring that the first push-pull rod 4 and the second push-pull rod 5 move synchronously, reducing the difference in the moving distance of the push-pull block 10, and improving the efficiency of clamping or releasing the heat-conducting plate 16.

[0042] like Figure 2 , 3As shown, the inner walls of the U-shaped fixing base 2 in this embodiment are provided with rotating grooves 19 on both sides. The two ends of the rotating rod 18 are respectively rotatably fitted in the corresponding rotating grooves 19. By cooperating with the rotating grooves 19, the stability of the rotation of the L-shaped rod 3 and the rotating rod 18 is improved.

[0043] like Figure 2 , 3 As shown, in this embodiment, a bearing 20 is installed on the circumference of the rotating groove 19. The bearing 20 is installed on the circumference of the rotating rod 18. The bearing 20 reduces the friction between the rotating rod 18 and the rotating groove 19, thereby reducing the probability of the rotating rod 18 disengaging from the rotating groove 19 during rotation.

[0044] like Figure 2 , 3 As shown, the L-shaped rod 3 in this embodiment has a first straight groove 21 at the bottom and a second straight groove 22 at the corner. A first crossbar 23 is installed between the two sides of the first straight groove 21. One end of the first push-pull rod 4 is rotatably engaged with the corresponding side of the first crossbar 23. A second crossbar 24 is installed between the two sides of the second straight groove 22. One end of the second push-pull rod 5 is rotatably engaged with the corresponding side of the second crossbar 24. Through the first straight groove 21 and the second straight groove 22, the probability of the L-shaped rod 3 obstructing the movement of the first push-pull rod 4 and the second push-pull rod 5 is reduced. The first crossbar 23 and the second crossbar 24 facilitate the pushing and pulling motion of the first push-pull rod 4 and the second push-pull rod 5 when the L-shaped rod 3 rotates.

[0045] like Figure 2 As shown, in this embodiment, the push-pull block 10 is provided with two fixing plates 25 on the side away from the clamping plate 12, and a fixing rod 26 is provided between the two fixing plates 25. The ends of the first push-pull rod 4 and the second push-pull rod 5 away from the L-shaped rod 3 are rotatably engaged with the corresponding fixing rod 26. Through the cooperation of the fixing plate 25 and the fixing rod 26, and by utilizing the pushing and pulling action of the first push-pull rod 4 and the second push-pull rod 5, the rotation of the L-shaped rod 3 is converted into the horizontal sliding of the push-pull block 10.

[0046] like Figure 2 , 3As shown, the upper side of the U-shaped fixing base 2 in this embodiment is provided with two limiting grooves 27, and a limiting plate 7 is placed on the lower side of the two limiting grooves 27. A connecting post 8 is installed on the upper side of the limiting plate 7, and an inverted U-shaped frame 6 is installed on the lower side. A lifting handle 9 is installed on the upper side of the connecting post 8, and the lifting handle 9 is located above the U-shaped fixing base 2. A slot 28 is provided on the lower side of the limiting grooves 27. Both the limiting grooves 27 and the slots 28 are connected to the hollow area of ​​the U-shaped fixing base 2. The two sides of the inverted U-shaped frame 6 are respectively engaged in the corresponding slots 28. Located on one side of the L-shaped rod 3, the second push-pull rod 5 passes through the hollow area of ​​the inverted U-shaped frame 6. A groove is provided on one side of the slot 28, and protrusions are provided on both sides of the inverted U-shaped frame 6. When the lifting handle 9 is lifted, the deformation of the lower part of the inverted U-shaped frame 6 causes the protrusions to be inserted into the groove or pulled out of the groove. The limiting groove 27 facilitates the stable placement of the limiting plate 7. The cooperation between the inverted U-shaped frame 6 and the slot 28 facilitates the restriction of the rotation of the L-shaped rod 3 and reduces the probability of the clamping plate 12 sliding due to accidental contact with the L-shaped rod 3 during clamping.

[0047] like Figure 1 , 2 As shown, in this embodiment, a hook seat 15 is slidably fitted on one of the clamping plates 12, and a groove 29 corresponding to the hook seat 15 is provided on one side. The vertical cross-section of the hook seat 15 is a U-shaped structure. The bottom of the hook seat 15 is slidably fitted in the groove 29. A cleaning component is installed on one side of the hook seat 15. The cleaning component is slidably fitted on the upper side of the heat-conducting plate 16. An internal channel is provided on the upper side of the groove 29. A limiting block is installed on the lower side of the inner wall of the hook seat 15, which is slidably fitted in the internal channel. The limiting block reduces the probability of the hook seat 15 disengaging from the clamping plate 12. The cooperation between the hook seat 15 and the groove 29 facilitates the improvement of the sliding stability of the cleaning component.

[0048] like Figure 1 , 2 As shown, the cleaning assembly of this embodiment includes a sliding plate 13 mounted on one side of the hook seat 15. A brush 17 is mounted on the lower side of the sliding plate 13. The brush 17 is located on the upper side of the heat-conducting plate 16. A handle 14 is mounted on the upper side of the sliding plate 13. Because the brush 17 is soft and deformable, the heat-conducting plate 16 can be tilted and removed during disassembly. By pushing and pulling the handle 14, it is convenient to use the sliding plate 13 to drive the brush 17 to clean the heat-conducting plate 16, thereby reducing the impact of dust on the heat dissipation effect of the heat-conducting plate 16.

[0049] Implementation 1: The upper side of the optical module body 1 is provided with two inverted T-shaped grooves 30, and the lower side of the clamping plate 12 is provided with an inverted T-shaped block 31 that slides in the inverted T-shaped grooves 30. The stability of the sliding of the clamping plate 12 is improved by the cooperation between the inverted T-shaped block 31 and the inverted T-shaped grooves 30.

[0050] Implementation 2: Both clamping plates 12 are provided with strip grooves 32 on their respective inner sides, and both sides of the heat-conducting plate 16 are provided with retaining strips 33. The retaining strips 33 are located in the corresponding strip grooves 32. By cooperating with the retaining strips 33 and the strip grooves 32, the stability of the clamping plates 12 clamping the heat-conducting plate 16 is improved.
