Description

[0002] The network transceiver motherboard is the core circuit board of fiber optic transceivers and optical modules. It is responsible for the conversion between optical and electrical signals and physical layer data processing, enabling long-distance transmission and connection between twisted-pair cables and optical fibers.

[0003] The heat dissipation structure for a network transceiver motherboard disclosed in Chinese Utility Model Patent Application Publication No. CN211506402U utilizes the excellent thermal conductivity of metal materials to conduct some of the heat generated by the network transceiver motherboard to the air for heat dissipation. However, this utility model is limited to centralized heat dissipation in the middle, resulting in poor overall airflow heat exchange. The airflow cannot be evenly diffused to the entire area of ​​the motherboard, leading to inadequate heat dissipation in some areas and severe local heat accumulation. Furthermore, the use of ventilation windows and holes in the shell for direct airflow between the inside and outside for heat dissipation is not suitable for environments with high dust levels. The entire unit is not airtight, and dust and moisture can easily enter the transceiver, causing dust accumulation on the motherboard and corrosion and aging of components. This makes it unsuitable for industrial or outdoor humid and dusty conditions. Summary of the Invention

[0034] Please see Figures 1-2 , Figure 7The dustproof component includes a limiting frame 9, a filter screen 8, a pressure plate 10, and a second fixing bolt 11.

[0035] Specifically, a limiting frame 9 is fixedly connected to the upper part of the upper housing 2. A filter screen 8 is placed inside the limiting frame 9. The lower part of the filter screen 8 fits against the upper housing 2 and corresponds to the upper part of the second air exchange port 12, thereby filtering the incoming air.

The lower part of the pressure plate 10 abuts against the filter screen 8, restricting the filter screen 8 inside the limiting frame 9, thereby achieving a stable filtration effect.

[0036] Please see Figures 1-2 The lower part of the upper housing 2 is fitted onto the outside of the side plate of the base 1. One side of the upper housing 2 is connected to the side plate of the base 1 by the first fixing bolt 4. There is a gap between the inside of the upper housing 2 and the upper part of the main board 16.

[0037] Specifically, the lower part of the upper shell 2 is fitted onto the outside of the side plate of the base 1. A first fixing bolt 4 is threadedly connected to one side of the upper shell 2, and one end of the first fixing bolt 4 is threadedly connected to the side plate of the base 1, thus fixing the upper shell 2 and the base 1 together. There is a gap between the inside of the upper shell 2 and the upper part of the main board 16, which facilitates the installation and use of the heat exchange pipes.

[0038] Working principle: During use, the heat dissipation structure is adjusted according to the site environment. In some dust-free environments, heat dissipation is performed on the motherboard 16. First, rotate the tube head 27 to flip the heat dissipation tube 20, and set the second air vent 12 at the end of the heat dissipation tube 20 downward, corresponding to the inside of the network transceiver. Then, connect the end of the fixing tube 21 to one end of the air pump 3 through the quick connector 26. Several clip brackets (not shown in the figure) are provided on the upper part of the upper housing 2 to fix the heat exchange pipe on the upper housing 2. Next, align the slot 13 on one side of the fixing plate 5 with the clip 17 and slide it in to limit the fixing plate 5 inside the fixing slot 7 opened on the side plate of the base 1. After limiting the fixing plate 5, put the upper housing 2 on the side plate of the base 1 to connect the upper housing 2 and the base 1. Connect one side of the upper housing 2 to the side plate of the base 1 through the first fixing bolt 4 to complete the installation of the network transceiver shell. The motherboard 16 is fixed inside the base 1 by bolts, and the different components of the motherboard 16 are connected to different connectors on the upper housing 2 through wires, thereby connecting to external wires.

[0039] At this time, the air pump 3 is activated, causing the first air exchange port 22 to draw in air, which is then transported to the interior of the fixed tube 21. Through the connecting pipes 15 on both sides, the air is distributed to the heat dissipation pipes 20 on both sides. The ends of the connecting pipes 15 are T-shaped tee pipes, each connected to one of the two L-shaped heat dissipation pipes 20. Finally, the air is discharged into the interior of the network transceiver through the second air exchange port 12 at the end of the heat dissipation pipe 20, blowing air onto the motherboard 16. The second air exchange ports 12 of the multiple heat dissipation pipes 20 disperse the air, increasing the uniformity of heat dissipation. The discharged air is then discharged through the heat dissipation holes 18 on the fixed plate 5 and the through holes in the upper housing 2, carrying away the heat inside the network transceiver, thus achieving uniform airflow cooling. The first air exchange port 22 can be connected to an air pipe, allowing the end of the air pipe to be placed in a dust-free environment, thus enabling the network transceiver to be used in a dust-free environment. When the motherboard 16 is in a dusty environment, to dissipate heat, firstly, rotate the heat pipe 20 so that the second vent 12 at the end of the heat pipe 20 is facing upwards and aligns with the through hole in the upper housing 2. Then, connect the fixing pipe 21 to one end of the air pump 3 via the quick connector 26. Several clip brackets (not shown in the figure) are provided on the upper part of the upper housing 2 to fix the heat exchange pipe. At this time, the second vent 12 is inserted into the through hole to complete the installation. Next, insert the heat dissipation fins 6 on one side of the temperature conducting plate 14 into the heat dissipation holes 18 in the fixing plate 5, with the heat dissipation fins 6 extending out of the fixing plate 5. The temperature conducting plate 14 and the fixing plate 5 are fitted together. The temperature conducting plate 14 and the fixing plate 5 are connected and fixed by the third fixing bolt 19. Then, the fixing plate 5 is installed on the upper part of the base 1 and fixed. Then place the filter screen 8 inside the limiting frame 9, and then connect the pressure plate 10 to the limiting frame 9 through the second fixing bolt 11. The pressure plate 10 presses down on the lower filter screen 8, and the filter screen 8 corresponds to the upper part of the second air exchange port 12.

[0040] At this time, the air pump 3 is started and rotated in reverse, causing the second air exchange port 12 to draw in air. The filter screen 8 filters and blocks dust from entering the heat exchange pipes and air pump 3, preventing dust from causing any impact. The drawn-in air enters the interior of the heat dissipation pipe 20, which is a pure copper metal pipe. The incoming air interacts with the heat inside the transceiver, and the exchanged air is then collected inside the fixed pipe 21 through the connecting pipe 15, and then discharged through the first air exchange port 22. The first air exchange port 22 can be connected to an air pipe to discharge the heat-carrying air over a longer distance, reducing the impact of ambient temperature, or recovering the heat for reuse. During heat exchange, the heat dissipation fins 6 and the temperature-conducting plate 14 cooperate to block the heat dissipation holes 18, keeping the interior of the transceiver sealed. The temperature-conducting plate 14 transfers the temperature inside the transceiver to the heat dissipation fins 6, which then discharge the heat to the outside, thus maintaining a seal and assisting in heat dissipation.

[0041] When the above two heat dissipation structures are in use, the middle of the connecting pipe 15 is connected to the mounting pipe 24, and the fan blade 25 is installed inside the mounting pipe 24 with the help of the support frame 23; when the air flows in the pipe, it impacts the fan blade 25 and makes it rotate, thereby increasing the air flow rate.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
