Description

Technical Field

[0001] This application relates to the technical field of fiber optic transceivers, and in particular to a high-density heat-dissipating fiber optic transceiver and its active air-cooling system. Background Technology

[0002] Fiber optic transceivers are core communication devices that convert electrical signals to optical signals and vice versa. They are widely used in data centers, 5G networks, and high-speed communication scenarios. With the increase in communication speed (such as the popularization of 400G / 800G optical modules), the heat generated by their internal high-power lasers, integrated circuits, and other electronic components increases dramatically. If the heat cannot be dissipated in time, it will lead to a decline in performance, and long-term high temperature will accelerate the aging of components, and may even lead to permanent damage.

[0003] Currently, most fiber optic transceivers use a passive or semi-active cooling solution with a fixed fan and ventilation holes. Its drawbacks include:

[0004] 1. Uneven airflow coverage: Fixed fans only blow air in a fixed direction (such as axial direction), resulting in ineffective heat dissipation for far-end components or blind spots (such as module corners);

[0005] 2. Thermal accumulation effect: Under high-density layout, the heat of adjacent modules is superimposed, and the local temperature rise is aggravated;

[0006] 3. Energy waste: The fan runs at full speed continuously, which is noisy and consumes a lot of power, and lacks dynamic control.

[0007] Therefore, there is an urgent need for a high-density heat-dissipating fiber optic transceiver and its active air-cooling system to solve this problem. Utility Model Content

[0008] To address the problem of uneven airflow coverage and inefficient heat dissipation caused by the internal heat dissipation components of current fiber optic transceivers, this application provides a high-density heat-dissipating fiber optic transceiver and its active air-cooling system.

[0012] A heat dissipation assembly for active air cooling is disposed within the mounting cavity, and the heat dissipation assembly includes a base, a mounting bracket, a support base, a support plate, a first transmission rod, fan blades, a drive unit, and an adjustment unit.

Through dynamic air cooling adjustment and structural optimization design, it solves the problems of uneven airflow coverage and low heat dissipation efficiency in traditional solutions. It uses a single drive mechanism to synchronously control the pitch angle of multiple fan blades, and achieves dynamic adjustment of airflow direction through mechanical linkage.

[0023] Optionally, the adjustment unit further includes a passive gear plate and a linkage gear plate. The passive gear plate is fixed to the connection end of the docking rod on the support plate, and the linkage gear plate is fixed to the connection end of the docking rod on the support seat.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses a high-density heat-dissipating fiber optic transceiver and its active air-cooling system.

Therefore, they should not be construed as limitations on this utility model.

[0040] Reference Figure 1 and Figure 2 A high-density heat-dissipating fiber optic transceiver and its active air-cooling system are disclosed. The transceiver includes a housing 1, heat dissipation holes 2, and a heat dissipation assembly 3. The housing 1 has heat dissipation holes 2 on its side wall, and an internal mounting cavity. The heat dissipation assembly 3 for active air cooling is located within the mounting cavity. The heat dissipation assembly 3 includes a base 31, a mounting bracket 32, a support 33, a support plate 34, a first transmission rod 35, fan blades 36, a drive unit, and an adjustment unit. This patent addresses the heat dissipation requirements of fiber optic transceivers by using dynamic air-cooling adjustment and structural optimization design to solve the problems of uneven airflow coverage and low heat dissipation efficiency in traditional solutions. A single drive mechanism synchronously controls the pitch angle of multiple fan blades 36, achieving dynamic adjustment of airflow direction through mechanical linkage. This eliminates the heat dissipation blind spots caused by traditional fixed fans, enhances heat exchange efficiency with the heat dissipation surface, and significantly improves heat dissipation performance. Simultaneously, the single drive structure synchronously controls multiple fan blades 36, effectively reducing production costs and subsequent maintenance costs.

[0041] Specifically, the base 31 is fixed to the side wall of the mounting cavity, the card holder 32 is fixed to the edge of the base 31, the support seat 33 is slidably engaged with the card holder 32, the support plate 34 is connected to one side of the support seat 33 through the adjustment unit, the first transmission rod 35 is rotatably connected to one end of the support plate 34, and the fan blade 36 is fixed to one end of the first transmission rod 35.

[0042] In this embodiment of the application, the driving unit includes a driven ball gear 37 and a driving ball gear 38. The driving ball gear 38 drives multiple driven ball gears 37 to mesh and link synchronously. Through the arrangement of the ball gears, the driven ball gears 37 can still mesh and link with the driving ball gear 38 when the angle changes.

[0043] Driven spherical gear 37 is coaxially fixed to one end of the first transmission rod 35 away from the fan blade 36, and driving spherical gear 38 is rotatably connected to the center of the support 33 and meshes with driven spherical gear 37.

[0044] A servo motor 39 is fixed at the center of the base 31, and a second transmission rod 310 is fixed at the shaft of the drive ball gear 38. The second transmission rod 310 is coaxially arranged with the output shaft of the servo motor 39 and is slidably engaged. A protrusion is provided on the side wall of the second transmission rod 310, and a sliding groove is provided in the output shaft of the servo motor 39. The protrusion is slidably engaged in the sliding groove.

[0045] In this embodiment, the servo motor 39 drives the second transmission rod 310 to rotate, which in turn drives the active ball gear 38 to rotate synchronously. The protrusions enable the second transmission rod 310 to slide synchronously with the output shaft of the servo motor 39.

[0046] Reference Figure 3 and Figure 4 Specifically, in this embodiment of the application, the adjustment unit includes an adjustment rod 311, a docking rod 312, a passive gear plate 313, and a linkage gear plate 314. By using the adjustment rod 311, when the distance between the base 31 and the support 33 changes, the docking rod 312 can be driven to move in tandem. The passive gear plate 313 and the linkage gear plate 314 mesh with each other, thereby changing the angle of the support plate 34.

[0047] In this embodiment, one end of the adjusting rod 311 is rotatably connected to the card seat 32, and the other end is rotatably connected to the docking rod 312. One end of the docking rod 312 is rotatably connected to the support seat 33, and the other end is rotatably connected to the support plate 34. The passive gear plate 313 is fixed on the support plate 34 at the connection end with the docking rod 312, and the linkage gear plate 314 is fixed on the support seat 33 at the connection end with the docking rod 312. The passive gear plate 313 and the linkage gear plate 314 mesh with each other.

[0048] Specifically, in this embodiment, a miniature cylinder 315 is fixed on the base 31. The telescopic part of the miniature cylinder 315 is fixed to the support 33. A high-precision temperature sensor array is integrated inside the fiber optic transceiver housing 1. Both the miniature cylinder 315 and the high-precision temperature sensor array are electrically connected to the electrical control equipment. By extending and retracting the telescopic part of the miniature cylinder 315, the distance between the base 31 and the support 33 can be adjusted. At the same time, by using the high-precision temperature sensor array, the heat source distribution inside the transceiver is monitored in real time, and air is preferentially directed to high-temperature areas to improve heat dissipation efficiency.

[0049] The overall structure composed of the support plate 34, the first transmission rod 35 and the fan blades 36 has at least three sets, and the three sets of structures are at a 120-degree angle to each other. By using the multiple sets of fan blades 36 and their connecting components, the effect of a single drive mechanism synchronously controlling multiple sets of fans can be achieved.

[0050] The implementation principle of a high-density heat dissipation fiber optic transceiver and its active air-cooling system in this application embodiment is as follows: During heat dissipation, the second transmission rod 310 is driven to rotate by the servo motor 39. At this time, the active ball gear 38 rotates synchronously and drives the driven ball gear 37 to mesh and link together. The driven ball gear 37 drives the first transmission rod 35 and the fan blade 36 to rotate, thereby driving airflow to achieve the heat dissipation effect. During heat dissipation, the high-precision temperature sensor array is set to monitor the heat source distribution inside the transceiver in real time, and the micro cylinder 315 is controlled to extend and retract by the electronic control equipment, thereby adjusting the distance between the base 31 and the support 33. During adjustment, the passive gear 313 meshes and links with the linkage gear 314, and synchronously drives the support plate 34 to deflect, thereby adjusting the angle of the fan blade 36.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
