Description

Technical Field

[0001] This utility model relates to the field of optical modems, and in particular to an optical modem with high-efficiency heat dissipation. Background Technology

[0002] An optical modem, also known as a single-port optical transceiver, is a product designed for specific user environments. It utilizes a pair of optical fibers for point-to-point optical transmission, providing a single E1, V.35, or 10BaseT connection. This device serves as a relay transmission device in local area networks and is suitable for fiber optic terminal transmission equipment in base stations and leased line equipment. Multi-port optical transceivers are generally simply called "optical transceivers," while single-port optical transceivers are typically used at the user end, functioning similarly to a baseband modem used for WAN leased lines (circuit connections), and are sometimes referred to as "optical modem" or "optical modem-modem."

[0003] In existing technologies, during the operation of an optical modem, the circuit board and its electronic components generate a significant amount of heat. This heat accumulates inside the modem, causing its temperature to rise and affecting its performance. To facilitate heat dissipation, multiple ventilation holes are typically created on the modem's casing to allow the accumulated heat to dissipate. However, this self-heating method using ventilation holes is ineffective, and the ventilation holes also allow dust from the outside air to enter the modem and accumulate on the electronic components. Over time, this weakens the heat dissipation of the electronic components, affecting their performance and thus reducing the modem's dustproof and heat dissipation capabilities. Utility Model Content

[0004] The main purpose of this invention is to provide an optical modem with high-efficiency heat dissipation, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An efficient heat dissipation optical modem includes an optical modem housing. A heat dissipation mechanism is provided inside the left side wall of the optical modem housing. The heat dissipation mechanism includes an inner shell, a cooling fan, and a heat dissipation cover. The inner shell is fixedly connected to the left side of the inner wall of the optical modem housing, and the cooling fan is fixedly connected to the inside of the inner shell via a threaded knob. The heat dissipation cover is fixedly connected to the left side wall of the optical modem housing. A dustproof mechanism is also provided inside the right side wall of the optical modem housing. The dustproof mechanism includes a dustproof mesh, a compression spring, a movable plate, and a limiting rod. Compression springs are fixedly connected to the inside of both sides of the top surface of the dustproof mesh, and the movable plate is fixedly connected to the top of the compression springs. The limiting rod is fixedly connected to the top surface of the movable plate.

[0007] Preferably, the left and right side walls of the optical modem housing are respectively provided with mounting openings, and the bottom surface of the mounting opening is provided with a set of symmetrical positioning notches, and the top surface of the mounting opening is provided with a set of symmetrical limiting grooves.

[0008] Preferably, the inner shell of the mechanism is fixedly installed on the inner left side wall of the optical modem shell, and the inner shell of the mechanism is located inside the dustproof mechanism on the left side of the optical modem shell. Three heat dissipation vents are opened in a horizontal array on the inner front wall of the mechanism, and positioning posts are fixedly installed on the inner front wall of the mechanism and on the four sides outside the heat dissipation vents. Threaded holes are opened on the front wall of the positioning posts.

[0009] Preferably, three cooling fans are provided, and mounting holes are respectively opened at the four corners of the front and rear walls of the cooling fans. The positioning pins are inserted into the mounting holes, and the threaded knobs are threadedly connected to the threaded holes.

[0010] Preferably, the front wall of the heat dissipation cover has several strip-shaped heat dissipation holes arranged in a horizontal array.

[0011] Preferably, a set of symmetrical positioning blocks corresponding to the positioning notches are fixedly installed on the top surfaces of the heat dissipation cover and the dustproof net, and the left and right sides of the top surfaces of the heat dissipation cover and the dustproof net are respectively provided with inner cavities. A through sliding opening is provided on the front end wall of the inner cavity, and a through passage is provided on the top surface of the inner cavity. The compression spring is fixedly installed on the bottom surface of the inner cavity, and the movable plate is fixedly installed on the top of the compression spring. The limiting rod is fixedly installed on the top surface of the movable plate and passes through the passage and is inserted into the limiting groove. A slider is also fixedly installed on the front end wall of the movable plate. The slider is movably installed in the sliding opening, and a pressure plate is also fixedly installed on the front end of the slider.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the heat dissipation and dustproof mechanisms work in conjunction with the optical modem. After the cooling fan is positioned and installed into the inner shell of the mechanism using a threaded knob, the heat dissipation cover and dustproof mesh are respectively installed into the mounting holes on the left and right sides of the optical modem's outer shell. During use, the cooling fan draws out the heat generated inside the optical modem's outer shell quickly and efficiently through the heat dissipation vents, and then exhausts the heat to the outside through the heat dissipation holes on the heat dissipation cover. Simultaneously, under the suction force of the cooling fan, cool outside air enters the optical modem's outer shell through the mounting hole on the right side and then enters the outer shell. During the process, dust can be filtered and intercepted through a dustproof net, preventing dust from entering the optical modem's casing along with the cold air. This further enables heat exchange and air cooling of the electronic components inside the optical modem's casing. Thus, by actively cooling the optical modem during use, the heat generated inside the optical modem can be dissipated in a timely manner, preventing heat accumulation that could affect the normal operation of the optical modem. At the same time, dustproofing during heat dissipation also prevents dust from entering the optical modem and affecting the normal operation of the electronic components, thereby giving the optical modem efficient heat dissipation and dustproof performance during use.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 - Figure 5 As shown, a high-efficiency heat dissipation optical modem includes an optical modem shell 1. A heat dissipation mechanism 2 is provided inside the left side wall of the optical modem shell 1. The heat dissipation mechanism 2 includes an inner shell 7, a cooling fan 11, and a heat dissipation cover 14. The inner shell 7 is fixedly connected to the left side of the inner wall of the optical modem shell 1, and the cooling fan 11 is fixedly connected to the inside of the inner shell 7 through a threaded knob 13. The heat dissipation cover 14 is fixedly connected to the left side wall of the optical modem shell 1. A dustproof mechanism 3 is also provided inside the right side wall of the optical modem shell 1. The dustproof mechanism 3 includes a dustproof net 16, a compression spring 21, a movable plate 22, and a limiting rod 23. Compression springs 21 are fixedly connected to the inside of both sides of the top surface of the dustproof net 16, and the movable plate 22 is fixedly connected to the top of the compression springs 21. The limiting rod 23 is fixedly connected to the top surface of the movable plate 22.

[0022] like Figure 4 As shown, mounting openings 4 are respectively provided on the left and right side walls of the optical modem shell 1. The mounting openings 4 are used to cooperate with the installation of the heat dissipation mechanism 2 and the dustproof mechanism 3. A set of symmetrical positioning notches 5 are provided on the inner bottom surface of the mounting opening 4. The positioning notches 5 are used to cooperate with the positioning installation of the heat dissipation cover plate 14 and the dustproof mesh 16. A set of symmetrical limiting grooves 6 are provided on the inner top surface of the mounting opening 4. The limiting grooves 6 are used to cooperate with the limiting installation of the heat dissipation cover plate 14 and the dustproof mesh 16.

[0023] like Figure 4 As shown, the inner shell 7 is fixedly installed on the inner left side wall of the optical modem shell 1, and the inner shell 7 is located inside the dustproof mechanism 3 on the left side of the optical modem shell 1. The inner shell 7 is used to install and place the cooling fan 11. Three heat dissipation vents 8 are opened in a horizontal array on the inner front wall of the inner shell 7. The heat dissipation vents 8 can ensure that the cooling fan 11 can absorb the heat generated inside the optical modem shell 1. The inner front wall of the inner shell 7 and the four sides outside the heat dissipation vents 8 are also fixedly installed with positioning posts 9. The positioning posts 9 can cooperate with the cooling fan 11 to play a positioning and installation role. The front wall of the positioning post 9 is provided with threaded holes 10. The threaded holes 10 are used to cooperate with the use of threaded knobs 13 to fix the cooling fan 11.

[0024] like Figure 4As shown, three cooling fans 11 are provided, and mounting holes 12 are respectively opened at the four corners of the front and rear walls of the cooling fans 11. The positioning pins 9 are inserted into the mounting holes 12, and the threaded knobs 13 are threaded together with the threaded holes 10. After the positioning pins 9 are inserted into the mounting holes 12, the threaded knobs 13 are threaded together with the threaded holes 10, so that the cooling fans 11 can be installed in the inner shell 7 of the mechanism. When the optical modem is running, the cooling fans 11 can draw out the heat inside the optical modem shell 1 in time through the heat dissipation port 8, so as to avoid the heat from accumulating inside the optical modem shell 1. At the same time, the outside cold air can also enter the optical modem shell 1 through the mounting port 4 on the right side to achieve heat exchange and air cooling for electronic components.

[0025] like Figure 4 As shown, several strip-shaped heat dissipation holes 15 are arranged in a horizontal array on the front wall of the heat dissipation cover 14. The heat drawn out by the cooling fan 11 will be discharged to the outside through the heat dissipation holes 15 on the heat dissipation cover 14.

[0026] like Figure 4 and Figure 5 As shown, a set of symmetrical positioning blocks 17 corresponding to the positioning notches 5 are fixedly installed on the top surfaces of the heat dissipation cover 14 and the dustproof net 16, respectively. The left and right sides of the top surfaces of the heat dissipation cover 14 and the dustproof net 16 each have an inner cavity 18. A through-slide 19 is opened on the front wall of the inner cavity 18, and a through-hole 20 is opened on the top surface of the inner cavity 18. A compression spring 21 is fixedly installed on the bottom surface of the inner cavity 18, and a movable plate 22 is fixedly installed on the top of the compression spring 21. A limiting rod 23 is fixedly installed on the top surface of the movable plate 22 and passes through the through-hole 20 and is inserted into the limiting groove 6. A slider 24 is also fixedly installed on the front wall of the movable plate 22, and the slider 24 is movably installed in the slide 19. A pressure plate 25 is also fixedly installed on the front end of the slider 24. When installing the heat dissipation cover 14 and the dustproof net 16, the positioning blocks 17 are positioned in a fixed position. After positioning the heat sink cover 14 and dust filter 16 at a certain angle in the notch 5, press the pressure plate 25 to allow the limiting rod 23 protruding from the top surface of the heat sink cover 14 or dust filter 16 to enter the inner cavity 18. Then push the heat sink cover 14 or dust filter 16 to fully enter the mounting port 4 and release the pressure on the pressure plate 25. This allows the compression spring 21 to elastically recover and extend, pushing the movable plate 22 upward and causing the slider 24 to slide within the sliding port 19 until the limiting rod 23 passes through the through port 20 and inserts into the limiting groove 6. The heat sink cover 14 and dust filter 16 can then be installed and fixed in the mounting ports 4 on the left and right sides of the optical modem housing 1. This method facilitates the subsequent disassembly and cleaning of the dust filter 16, preventing excessive dust from clogging the mesh and affecting the cooling efficiency of the external cold air for the electronic components.

[0027] It should be noted that this utility model is a high-efficiency heat dissipation optical modem. Before use, the three cooling fans 11 are sequentially installed through the mounting port 4 on the left side of the optical modem housing 1 into the inner shell 7 located on the left side wall of the optical modem housing 1, inside the mounting port 4. During installation, the corresponding positioning pins 9 installed inside the inner shell 7 are inserted into the corresponding mounting holes 12 on the cooling fans 11, and the threaded knobs 13 are screwed into the threaded holes 10 at the front end of the positioning pins 9 to connect them. In this way, the cooling fans 11 can be installed and fixed inside the inner shell 7. Then, the heat dissipation cover 14 is installed into the mounting port 4 on the left side of the optical modem housing 1. During installation, the symmetrical positioning blocks 1 on the bottom surface of the heat dissipation cover 14 are installed. 7 is placed in the corresponding positioning notch 5 opened on the inner bottom surface of the mounting port 4. At this time, the heat dissipation cover 14 is blocked by the limiting rods 23 protruding on both sides of the top surface and cannot be fully inserted into the mounting port 4. The pressure plate 25 located on the upper sides of the front wall of the heat dissipation cover 14 can be pressed against it. The pressure plate 25 will drive the slider 24 to slide in the sliding port 19, and the slider 24 will drive the limiting rod 23 to move downward in the inner cavity 18, and force the compression spring 21 to retract until the limiting rod 23 installed on the top surface of the movable plate 22 enters the inner cavity 18 through the through port 20. Keep the pressing force on the pressure plate 25 unchanged, and push the heat dissipation cover 14 again to make the heat dissipation cover 14 fully inserted into the mounting port 4. Then, release the pressing force on the pressure plate 25. The compression spring 21 is allowed to elastically extend and push the movable plate 22 upwards. This causes the limiting rod 23 on the top surface of the movable plate 22 to pass through the through-hole 20 and insert into the corresponding limiting groove 6 on the inner top surface of the mounting port 4. This allows the heat dissipation cover 14 to be installed and fixed in the mounting port 4 on the left side of the optical modem housing 1. Similarly, the dust filter 16 is then installed and fixed in the mounting port 4 on the right side of the optical modem housing 1 using the same method as the heat dissipation cover 14. During use, the cooling fan 11 will run synchronously, accelerating the airflow inside the optical modem housing 1 and dissipating the heat generated by the electronic components inside the optical modem housing 1 through the heat dissipation vents 8 on the inner shell 7. The heat is extracted and discharged through several strip-shaped heat dissipation holes 15 on the heat dissipation cover 14. In this way, the heat dissipation rate inside the optical modem casing 1 can be improved through active cooling. At the same time, under the suction force of the cooling fan 11, the outside cold air will enter the optical modem casing 1 through the mounting port 4 on the right side. When the outside cold air enters the optical modem casing 1, it will pass through the dust filter 16 installed in the mounting port 4 on the right side. The dust filter 16 will intercept and filter the dust carried by the outside cold air, preventing dust from entering the optical modem casing 1 and covering the electronic components, thus affecting the normal heat dissipation of the electronic components. The cold air entering the optical modem casing 1 will carry away the heat from the electronic components according to the principle of heat exchange.Furthermore, the system enables air cooling for electronic components. By allowing cool air to enter through the right side of the optical modem casing 1 and expelling heat through the left side, the ventilation and heat dissipation efficiency of the optical modem during use is improved. This results in highly efficient heat dissipation and dustproof performance. To prevent dust from clogging the mesh of the dustproof mesh 16 and affecting ventilation and heat dissipation efficiency over prolonged use, the dustproof mesh 16 can be periodically removed for cleaning. To remove it, simply press the pressure plate 25 until it cannot be pressed further, causing the limiting rod 23 to disengage from the limiting groove 6 and enter the inner cavity 18. This allows the dustproof mesh 16 to be removed from the mounting port 4 on the right side of the optical modem casing 1.
