[0029] The following is combined with Figures 1-3 Detailed description of the wireless terminal access device 10 according to an embodiment of the present utility model.

[0030] Reference Figure 1 and Figure 2As shown, the wireless terminal access device 10 according to an embodiment of the present invention includes a communication module 1 and a liquid cooling assembly 2. The liquid cooling assembly 2 includes: a first liquid cooling plate 21, a second liquid cooling plate 22, a liquid storage tank 23, an inlet pipe 24, an outlet pipe 25, and a liquid pump 26. The communication module 1 is sandwiched between the first liquid cooling plate 21 and the second liquid cooling plate 22. The liquid storage tank 23 stores coolant. The first liquid cooling plate 21 and the second liquid cooling plate 22 are connected to the liquid storage tank 23 through the inlet pipe 24. The first liquid cooling plate 21 and the second liquid cooling plate 22 are also connected to the liquid storage tank 23 through the outlet pipe 25. The inlet pipe 24 and / or the outlet pipe 25 are equipped with a liquid pump 26.

[0031] It is understood that the liquid cooling component 2 can provide liquid cooling for the communication module 1. The communication module 1 is sandwiched between the first liquid cooling plate 21 and the second liquid cooling plate 22, which can effectively increase the heat exchange area between the liquid cooling component 2 and the communication module 1. This is beneficial to improving the heat exchange efficiency between the coolant and the communication module 1, improving the heat dissipation efficiency of the communication module 1, and facilitating the rapid cooling of the communication module 1. This reduces the risk of overheating of the communication module 1, thereby promoting the stable, reliable, and efficient operation of the communication module 1. Furthermore, compared to air cooling through a fan, this embodiment has no wind noise pollution, which is beneficial to improving the user experience and thus enhancing the product competitiveness of the wireless terminal access device 10.

[0032] Specifically, the communication module 1 can have high-speed wireless signal transmission and conversion functions. The communication module 1 will generate heat during operation. The coolant in the storage tank 23 can flow into the first liquid cooling plate 21 and the second liquid cooling plate 22 through the liquid inlet pipe 24. The coolant can exchange heat with the communication module 1 through the first liquid cooling plate 21 and the second liquid cooling plate 22 to absorb the heat of the communication module 1 and cool the communication module 1, thereby realizing liquid cooling heat dissipation of the communication module 1, reducing the risk of overheating of the communication module 1, and helping to ensure the stable, reliable and efficient operation of the communication module 1. The coolant after absorbing heat can flow back into the storage tank 23 through the liquid outlet pipe 25 to realize the circulation of coolant.

[0033] The inlet pipe 24 and / or outlet pipe 25 are equipped with a liquid pump 26. That is, the inlet pipe 24 may be equipped with a liquid pump 26, or the outlet pipe 25 may be equipped with a liquid pump 26, or both the inlet pipe 24 and the outlet pipe 25 may be equipped with a liquid pump 26. The liquid pump 26 can provide the power for the circulation of coolant, accelerate the flow of coolant, and facilitate the rapid flow of coolant in the storage tank 23 to the first liquid cooling plate 21 and the second liquid cooling plate 22 to quickly cool the communication module 1.

[0034] Among them, the wireless terminal access device 10 can be a 5G CPE machine, the communication module 1 can include a connected circuit board 11 (PCBA) and chip 12, and the coolant can be cooling water or cooling oil.

[0035] According to the embodiment of the present invention, the liquid cooling component 2 of the wireless terminal access device 10 can perform liquid cooling heat dissipation on the communication module 1. The communication module 1 is sandwiched between the first liquid cooling plate 21 and the second liquid cooling plate 22 of the liquid cooling component 2, which can effectively increase the heat exchange area between the liquid cooling component 2 and the communication module 1, which is conducive to improving the heat exchange efficiency between the coolant and the communication module 1, improving the heat dissipation efficiency of the communication module 1, and facilitating the rapid cooling of the communication module 1, reducing the risk of overheating of the communication module 1. This is conducive to the stable, reliable and efficient operation of the communication module 1, and there is no wind noise pollution, which is conducive to improving the user experience and thus enhancing the product competitiveness of the wireless terminal access device 10.

[0036] In some embodiments of this utility model, reference is made to Figures 1-3 As shown, the first liquid cooling plate 21 includes a first heat-conducting block 211 and a plurality of first heat-conducting pipes 212. The first heat-conducting block 211 is attached to one side of the communication module 1, and the plurality of first heat-conducting pipes 212 pass through the first heat-conducting block 211 and are connected in parallel between the liquid inlet pipe 24 and the liquid outlet pipe 25. The second liquid cooling plate 22 includes a second heat-conducting block 221 and a plurality of second heat-conducting pipes 222. The second heat-conducting block 221 is attached to the other side of the communication module 1, and the plurality of second heat-conducting pipes 222 pass through the second heat-conducting block 221 and are connected in parallel between the liquid inlet pipe 24 and the liquid outlet pipe 25.

[0037] Understandably, multiple first heat pipes 212 are connected in parallel between the inlet pipe 24 and the outlet pipe 25. The coolant in the storage tank 23 can flow through the inlet pipe 24 to the multiple first heat pipes 212 and multiple second heat pipes 222. The coolant in each first heat pipe 212 can exchange heat with the communication module 1 through the first heat-conducting block 211, and the coolant in each second heat pipe 222 can exchange heat with the communication module 1 through the second heat-conducting block 221. The first heat-conducting block 211 and the second heat-conducting block 221 can effectively increase the heat exchange area between the liquid cooling component 2 and the communication module 1, which is conducive to improving the heat exchange efficiency between the coolant and the communication module 1, improving the heat dissipation efficiency, and facilitating the rapid cooling of the communication module 1. After exchanging heat with the communication module 1, the coolant in the first heat pipes 212 and the second heat pipes 222 can flow back into the storage tank 23 through the inlet pipe 24.

[0038] Specifically, the coolant in the multiple first heat pipes 212 can exchange heat with the first heat-conducting block 211 at different positions to make the first heat-conducting block 211 cool down evenly, and the coolant in the multiple second heat pipes 222 can exchange heat with the second heat-conducting block 221 at different positions to make the second heat-conducting block 221 cool down evenly. After cooling down, the first heat-conducting block 211 and the second heat-conducting block 221 can exchange heat with the communication module 1 on both sides of the communication module 1, which is conducive to the uniform heat dissipation of the communication module 1 and reduces the risk of local overheating of the communication module 1.

[0039] Multiple first heat pipes 212 are arranged in parallel, which can shorten the length of a single first heat pipe 212, shorten the flow path of the coolant, and increase the heat exchange area, which is beneficial to improving the heat exchange efficiency between the coolant and the first heat-conducting block 211. Multiple second heat pipes 222 are arranged in parallel, which can shorten the length of a single second heat pipe 222, shorten the flow path of the coolant, and increase the heat exchange area, which is beneficial to improving the heat exchange efficiency between the coolant and the second heat-conducting block 221.

[0040] Both the first heat-conducting block 211 and the second heat-conducting block 221 can be constructed as aluminum blocks, and both the first heat-conducting pipe 212 and the second heat-conducting pipe 222 can be constructed as copper pipes. The first heat-conducting block 211 and multiple first heat-conducting pipes 212 can be integrally formed by a die-casting process, and the second heat-conducting block 221 and multiple second heat-conducting pipes 222 can be integrally formed by a die-casting process. Thermally conductive silicone can be filled between the first heat-conducting block 211 and the communication module 1 to improve the heat exchange efficiency between the first heat-conducting block 211 and the communication module 1, and thermally conductive silicone can be filled between the second heat-conducting block 221 and the communication module 1 to improve the heat exchange efficiency between the second heat-conducting block 221 and the communication module 1, which is beneficial for the rapid cooling of the communication module 1.

[0041] In some embodiments of this utility model, there may be multiple chips 12. Some chips 12 are disposed on the side of the circuit board 11 near the first heat-conducting block 211, and other chips 12 are disposed on the side of the circuit board 11 near the second heat-conducting block 221. The chips 12 protrude relative to the circuit board 11. The side of the first heat-conducting block 211 near the circuit board 11 and the side of the second heat-conducting block 221 near the circuit board 11 may be provided with grooves corresponding to the chips 12, so that the first heat-conducting block 211 and its corresponding chip 12 can be attached, and the second heat-conducting block 221 and its corresponding chip 12 can be attached, which is beneficial to increasing the heat exchange area and improving the heat dissipation efficiency of the chips 12.

[0042] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the liquid cooling assembly 2 also includes an inlet valve 27 and an outlet valve 28. The inlet valve 27 is located on the inlet pipe 24 and is used to connect the inlet pipe 24 from the storage tank 23 to the first liquid cooling plate 21 and the second liquid cooling plate 22. The outlet valve 28 is located on the outlet pipe 25 and is used to connect the outlet pipe 25 from the first liquid cooling plate 21 and the second liquid cooling plate 22 to the storage tank 23.

[0043] Understandably, the inlet valve 27 and outlet valve 28 can precisely control the flow direction of the coolant, allowing the coolant to flow in the following direction: reservoir 23 → inlet pipe 24 → first liquid cooling plate 21 and second liquid cooling plate 22 → outlet pipe 25 → reservoir 23. This achieves unidirectional circulation of the coolant, effectively solving problems such as short circuits, cavitation, and air resistance, avoiding affecting the heat exchange efficiency between the coolant and the communication module 1, reducing the risk of overheating of the communication module 1, and improving the operational reliability of the liquid cooling assembly 2.

[0044] In some embodiments of this utility model, both the inlet valve 27 and the outlet valve 28 can be configured as one-way valves.

[0045] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the liquid storage tank 23 includes: a tank body 231, which has a liquid storage chamber 2311, a liquid outlet 2312 and a liquid inlet 2313. The liquid storage chamber 2311 stores coolant. The liquid storage chamber 2311 is connected to the liquid inlet pipe 24 through the liquid outlet 2312. The liquid outlet pipe 25 is connected to the liquid storage chamber 2311 through the liquid inlet 2313. The height of the liquid outlet 2312 is lower than the height of the liquid inlet 2313.

[0046] Understandably, the coolant in the storage chamber 2311 can flow sequentially through the outlet hole 2312 and the inlet pipe 24 to the first liquid cooling plate 21 and the second liquid cooling plate 22. The coolant can exchange heat with the communication module 1 through the first liquid cooling plate 21 and the second liquid cooling plate 22 to absorb the heat of the communication module 1 and cool it down. After absorbing heat, the coolant can flow back to the storage tank 23 sequentially through the outlet pipe 25 and the inlet hole 2313 to realize the circulation of the coolant.

[0047] The coolant in the storage chamber 2311 can be stratified according to temperature. That is, the coolant with higher temperature has a lower density and can float upwards, distributed in the upper layer, while the coolant with lower temperature has a higher density and can flow downwards, distributed in the lower layer. The height of the outlet hole 2312 is lower than the height of the inlet hole 2313. The temperature of the coolant in the storage chamber 2311 near the outlet hole 2312 is lower than the temperature of the coolant near the inlet hole 2313. This helps to ensure that the temperature of the coolant flowing to the first liquid cooling plate 21 and the second liquid cooling plate 22 is lower, which can improve the heat exchange efficiency between the coolant in the first liquid cooling plate 21 and the second liquid cooling plate 22 and the communication module 1, thereby improving the heat dissipation efficiency of the communication module 1.

[0048] Reference Figure 1As shown, the tank 231 has a liquid replenishment hole 2314, which is connected to the liquid storage chamber 2311. Coolant can be replenished into the liquid storage chamber 2311 through the liquid replenishment hole 2314. The coolant in the liquid storage chamber 2311 can exchange heat with the outside air through the tank 231 to achieve natural heat dissipation and cooling. The outside of the tank 231 may have heat dissipation fins, which can increase the surface area of ​​the tank 231, thereby improving the heat exchange efficiency between the coolant and the air.

[0049] In some embodiments of this utility model, the liquid level of the coolant in the liquid storage chamber 2311 is lower than the height of the liquid inlet hole 2313, which can prevent the coolant in the liquid storage chamber 2311 from flowing into the liquid outlet pipe 25 through the liquid inlet hole 2313. This helps to reduce the flow resistance of the coolant in the first liquid cooling plate 21 and the second liquid cooling plate 22 flowing back to the liquid storage tank 23 through the liquid outlet pipe 25, which is conducive to the smooth circulation of the coolant and improves the heat dissipation efficiency.

[0050] In some embodiments of this utility model, the liquid outlet 2312 is detachably connected to the liquid inlet pipe 24, and the liquid inlet 2313 is detachably connected to the liquid outlet pipe 25, so as to facilitate the assembly and disassembly of the liquid storage tank 23.

[0051] Understandably, when installing the liquid storage tank 23, the inlet pipe 24 can be inserted into the outlet hole 2312 and the outlet pipe 25 can be inserted into the inlet hole 2313, so that the outlet hole 2312 is connected to the inlet pipe 24 and the inlet hole 2313 is connected to the outlet pipe 25. When disassembling the liquid storage tank 23, the liquid storage tank 23 can be pulled out by force to separate the inlet pipe 24 from the outlet hole 2312 and the outlet pipe 25 from the inlet hole 2313, which facilitates the disassembly of the liquid storage tank 23 and reduces the difficulty of disassembling and assembling the liquid storage tank 23, making it easier to replace the liquid storage tank 23, thereby reducing the maintenance difficulty of the wireless terminal access device 10.

[0052] In some embodiments of this utility model, the liquid storage tank 23 further includes: a liquid outlet plug and an elastic element. Both the elastic element and the liquid outlet plug are disposed in the liquid storage cavity 2311. The liquid outlet plug is connected to the inner wall of the liquid storage cavity 2311 through the elastic element. When the liquid outlet 2312 is separated from the liquid inlet pipe 24, the elastic element drives the liquid outlet plug to block the liquid outlet 2312. When the liquid outlet 2312 is inserted and connected to the liquid inlet pipe 24, the liquid inlet pipe 24 passes through the liquid outlet 2312 and separates the liquid outlet plug from the liquid outlet 2312.

[0053] Understandably, when the outlet hole 2312 is separated from the inlet pipe 24, the elastic element drives the outlet plug to seal the outlet hole 2312, so as to prevent the coolant in the storage tank 23 from flowing out through the outlet hole 2312 when the storage tank 23 is not installed, thus preventing coolant leakage and facilitating the storage and transportation of the storage tank 23. When the outlet hole 2312 is connected to the inlet pipe 24, the inlet pipe 24 passes through the outlet hole 2312 and separates the outlet plug from the outlet hole 2312, so that the coolant in the storage tank 23 can flow into the inlet pipe 24.

[0054] The elastic element can be a spring, and the liquid outlet plug can be made of rubber. When the liquid outlet hole 2312 is separated from the liquid inlet pipe 24, it helps to ensure the sealing effect of the liquid outlet plug.

[0055] In some embodiments of this utility model, reference is made to Figure 2 As shown, the wireless terminal access device 10 also includes: a housing 3, which defines an installation cavity 31. The communication module 1, the first liquid cooling plate 21, and the second liquid cooling plate 22 are all located inside the installation cavity 31. The liquid storage tank 23 is located outside the installation cavity 31 and is detachably connected to the housing 3.

[0056] Understandably, the housing 3 can protect the communication module 1, the first liquid cooling plate 21 and the second liquid cooling plate 22 located in the mounting cavity 31. The liquid storage tank 23 is located outside the mounting cavity 31 and is detachably connected to the housing 3. When it is necessary to replace the liquid storage tank 23 to maintain the liquid cooling component 2, the liquid storage tank 23 can be disassembled and installed outside the mounting cavity 31. The operating space is large, which facilitates the replacement of the liquid storage tank 23 and helps to reduce the maintenance difficulty of the liquid cooling component 2.

[0057] The liquid storage tank 23 and the shell 3 can be detachably connected by a snap-fit ​​connection, or they can be detachably connected by fasteners, which can be screws, bolts and nuts.

[0058] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the wireless terminal access device 10 also includes: a first bracket 4 and a second bracket 5. The first bracket 4 and the second bracket 5 are both fixed in the mounting cavity 31. At least a portion of the first bracket 4 is connected to the communication module 1 on the side of the first liquid cooling plate 21 away from the communication module 1. At least a portion of the second bracket 5 is connected to the communication module 1 on the side of the second liquid cooling plate 22 away from the communication module 1.

[0059] It is understood that the first bracket 4 and the second bracket 5 are used to support the overall structure composed of the first liquid cooling plate 21, the communication module 1, and the second liquid cooling plate 22, so that the overall structure of the first liquid cooling plate 21, the communication module 1, and the second liquid cooling plate 22 is firmly and reliably installed in the mounting cavity 31. Specifically, the first liquid cooling plate 21 and the second liquid cooling plate 22 can be connected to both sides of the communication module 1 by fasteners, and the communication module 1 can be connected to the first bracket 4 and the second bracket 5 by fasteners, so that the overall structure of the first liquid cooling plate 21, the communication module 1, and the second liquid cooling plate 22 is installed between the first bracket 4 and the second bracket 5. Then, the first bracket 4 and the second bracket 5 can be fixed in the mounting cavity 31, thereby making the overall structure of the first liquid cooling plate 21, the communication module 1, and the second liquid cooling plate 22 firmly and reliably installed in the mounting cavity 31. Among them, the fasteners can be screws, bolts, and nuts.

[0060] In some embodiments of this utility model, the housing 3 has heat dissipation holes that communicate with the mounting cavity 31, which is beneficial for the communication module 1 to dissipate heat quickly.

[0061] It is understandable that the air outside the wireless terminal access device 10 can flow into the mounting cavity 31 through the heat dissipation holes. After the first liquid cooling plate 21 and the second liquid cooling plate 22 exchange heat with the communication module 1, they can be naturally cooled by the air to carry away the heat absorbed by the first liquid cooling plate 21 and the second liquid cooling plate 22 from the communication module 1, thereby achieving further heat dissipation of the communication module 1. This is conducive to the rapid cooling of the communication module 1, reducing the risk of overheating of the communication module 1, and thus promoting the stable, reliable and efficient operation of the communication module 1.

[0062] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the shell 3 includes a top cover 32, a shell body 33, and a bottom cover 34, which, in the direction of gravity, i.e. Figure 2 In the vertical direction, the top cover 32 is detachably connected to the upper end of the shell body 33, and the bottom cover 34 is detachably connected to the lower end of the shell body 33. The top cover 32, the shell body 33 and the bottom cover 34 together define the mounting cavity 31. The first bracket 4 and the second bracket 5 can both be fixedly connected to the shell body 33.

[0063] Both the top cover 32 and the bottom cover 34 are provided with heat dissipation holes. Air can enter the mounting cavity 31 through the heat dissipation holes of the bottom cover 34. The air entering the mounting cavity 31 carries away the heat of the communication module 1 through the first liquid cooling plate 21 and the second liquid cooling plate 22. After absorbing heat and heating up, the air can flow upward and can be discharged to the atmosphere through the heat dissipation holes of the top cover 32, realizing natural convection heat dissipation. This can effectively cool the first liquid cooling plate 21 and the second liquid cooling plate 22, thereby facilitating the cooling and heat dissipation of the communication module 1 by the first liquid cooling plate 21 and the second liquid cooling plate 22.

[0064] In some embodiments of this utility model, the wireless terminal access device 10 further includes a controller. The controller is communicatively connected to the liquid pump 26 and stores a software program. When the heating temperature of the communication module 1 reaches a critical temperature, the controller can control the liquid pump 26 to start pumping coolant through the software program. The coolant quickly removes the heat generated by the communication module 1 through the copper pipes in the first liquid cooling plate 21 and the second liquid cooling plate 22 (at the same time, the first liquid cooling plate 21 and the second liquid cooling plate 22 will also dissipate heat naturally through the air). The coolant through the copper pipes returns to the storage tank 23. When the communication module 1 cools down rapidly and reaches a certain safe value, the controller can control the liquid pump 26 to stop working through the software program. The coolant in the storage tank 23 will also be cooled by natural heat dissipation through the air. When the temperature of the communication module 1 reaches the critical value again, the liquid pump 26 can be restarted through the software program. This cycle repeats to ensure that the temperature of the communication module 1 does not exceed the critical value, thereby helping to ensure the normal operation of the wireless terminal access device 10. The critical value can be 95°C.

[0065] According to the embodiment of the present invention, the wireless terminal access device 10 uses liquid cooling component 2 to cool the communication module 1, which can improve heat dissipation efficiency and facilitate rapid cooling of the communication module 1. Liquid cooling component 2 is suitable for wireless terminal access devices 10 with high power consumption and high heat generation. Compared with the method of adding a fan to achieve air heat dissipation, the wireless terminal access device 10 of this embodiment can prevent dust and other substances from entering the installation cavity 31 and has no wind noise pollution, which is conducive to improving the user experience and thus improving the product competitiveness of wireless terminal access device 10.
