Description

Technical Field

[0001] This utility model relates to the field of communication base station technology, and specifically to a low-power communication base station device. Background Technology

[0002] Communication base stations are the core infrastructure of wireless communication networks. They are mainly used to receive, transmit, and process wireless signals, enabling user equipment to connect to the communication network. The associated equipment of a communication base station includes a baseband processing unit, a radio frequency unit, an antenna system, a transmission system, and a positioning system. The positioning system typically uses a GPS or BeiDou receiver to provide precise clock synchronization for the base station (such as the nanosecond-level synchronization required for 5G base stations), ensuring signal coordination among multiple base stations and avoiding interference.

[0003] Because the positioning system of a base station generates a lot of heat during long-term operation, high temperatures can cause the performance of related equipment inside the positioning system to degrade and increase power consumption. Therefore, heat sinks are needed to assist in heat dissipation and reduce the temperature of the equipment.

[0004] While existing positioning devices offer numerous advantages during use, they still suffer from several drawbacks. Their heat dissipation efficiency is inadequate. Because these devices are installed inside a protective casing, heat dissipation relies solely on the heat dissipation fins on the outer side of the casing. This single airflow path results in low heat dissipation efficiency, and the devices cannot adapt their heat dissipation efficiency to the device's temperature. Consequently, low ambient temperatures can negatively impact the normal operation of the equipment. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a low-power communication base station device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a low-power communication base station equipment device, including a protective shell, a threaded sleeve, an air inlet cover, and ventilation holes. A shell cover is rotatably connected to one side of the outer wall of the protective shell. The outer wall of the shell cover is welded with equally spaced parallel heat dissipation fins. Equally spaced parallel threaded holes are opened inside the heat dissipation fins. Threaded sleeves are threadedly connected inside the threaded holes. A support block is interference-fitted to one side of the inner wall of the threaded sleeve. Assembly holes are symmetrically opened on both sides of the outer wall of the support block. Air inlets are provided on both sides of the outer wall of the support block. A baffle plate is welded to one side of the outer wall of the air inlet cover. Guide rods are welded to both sides of the outer wall of the baffle plate. A thermally expanded rubber strip is bonded and fixed to one end of the guide rod. A plug is welded to one side of the inner wall of the air inlet cover.

[0007] By adopting the above technical solution, the assembly holes distributed on both sides of the support block are arranged in a cross pattern. The required equipment of the communication base station is installed inside the protective shell and cover for use. When the equipment heats up, the temperature of the equipment is transferred to the thermal expansion rubber strip through the cover, heat dissipation fins, threaded sleeve and support block. The thermal expansion rubber strip expands when heated and pushes the guide rod and air inlet shroud to move until the plug is disengaged from the ventilation hole. This, in conjunction with the ventilation hole, realizes natural convection of air inside the heat dissipation fins, increases the airflow trajectory on the outside of the heat dissipation fins, increases the heat dissipation area of ​​the heat dissipation fins, and improves the heat dissipation efficiency of the heat dissipation fins. After the equipment temperature drops, the thermal expansion rubber strip shrinks due to heat loss, driving the air inlet shroud to reset and the plug to reset and seal the ventilation hole, reducing the entry of external dust into the ventilation hole, ensuring the smoothness of the ventilation hole for the next use, and thus adjusting the airflow trajectory on the outside of the heat dissipation fins, adjusting the heat dissipation efficiency of the heat dissipation fins, ensuring that the equipment can adapt to different ambient temperatures and ensuring the normal operation of the equipment.

[0008] Specifically, the upper outer wall of the protective shell is provided with antennas that are equally spaced and parallel. Connectors are symmetrically installed on the upper and lower outer walls of the protective shell and the shell cover, and the protective shell is connected to the shell cover by screws through the connectors.

[0009] By adopting the above technical solution, the equipment inside the protective shell can transmit and receive signals through the antenna, and the connectors ensure the stability of the connection between the protective shell and the shell cover, ensuring the protection of the equipment inside the protective shell and the shell cover, and facilitating the disassembly and rotation of the shell cover, so as to facilitate the maintenance of the equipment inside the protective shell by the staff.

[0010] Specifically, the support block has ventilation holes inside, and the inner walls of the ventilation holes are designed with a tapered shape on both sides, and the size of the ventilation holes is adapted to the size of the plug.

[0011] By adopting the above technical solution, the ambient gas can flow and dissipate heat inside the heat dissipation fins through the air inlet shroud and ventilation holes. The conical shape can ensure the flow speed of air inside the ventilation holes based on the slit effect, ensuring the convective heat dissipation effect. When the plug fits against the inner wall of the ventilation hole, it can block the ventilation hole and ensure that the airflow is controlled to flow inside the ventilation hole.

[0012] Specifically, the diameters of the guide rod and the thermal expansion rubber strip are both smaller than the inner diameter of the assembly hole, and both the guide rod and the thermal expansion rubber strip are located inside the assembly hole. The outer wall of the end of the thermal expansion rubber strip away from the guide rod is bonded and fixed to the inner wall of the assembly hole.

[0013] By adopting the above technical solution, the thermal expansion rubber strip is bonded to the inner wall of the assembly hole and the guide rod at both ends, which can ensure the relatively stable position of the thermal expansion rubber strip. The guide rod and the assembly hole can limit the expansion direction of the thermal expansion rubber strip, ensuring that the expansion force of the thermal expansion rubber strip is transmitted to the guide rod axially, thus ensuring the driving accuracy of the air inlet hood. The thermal expansion rubber strip can expand by 150%-300% in the temperature range of 60-120 degrees Celsius, ensuring that the moving distance of the air inlet hood can adapt to the equipment temperature.

[0014] Specifically, a maintenance plate is snapped onto one side of the inner wall of the assembly hole, and the maintenance plate does not come into contact with the thermal expansion rubber strip.

[0015] By adopting the above technical solution, staff can visually observe the thermal expansion rubber strip through the assembly hole by disassembling the inspection plate, thereby observing the condition of the thermal expansion rubber strip and helping staff to replace the thermal expansion rubber strip in a timely manner.

[0016] Specifically, the plug adopts a conical shape design, is located inside the ventilation hole, and is in contact with the inner wall of the ventilation hole.

[0017] By adopting the above technical solution, the conical shape is not easy to accumulate water, avoiding the accumulation of liquid inside the ventilation hole, and the plug can seal both ends of the ventilation hole.

[0018] Specifically, a sealing ring is bonded and fixed to the outer wall of the shield, and the sealing ring is in contact with the inner wall of the threaded sleeve.

[0019] By adopting the above technical solution, the sealing ring ensures the sealing between the baffle plate and the threaded sleeve, and ensures that the flow trajectory of gas inside the ventilation hole and air inlet hood is controlled.

[0020] The beneficial effects of this utility model are:

[0021] (1) The low-power communication base station equipment device described in this utility model has ventilation holes that enable natural convection of air inside the heat dissipation fins, increase the airflow trajectory outside the heat dissipation fins, increase the heat dissipation area of ​​the heat dissipation fins, and improve the heat dissipation efficiency of the heat dissipation fins.

[0022] (2) The low-power communication base station device described in this utility model can adjust the airflow trajectory on the outside of the heat dissipation fins and adjust the heat dissipation efficiency of the heat dissipation fins, so as to ensure that the device can adapt to different ambient temperatures and ensure the normal operation of the device.

[0030] 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.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the low-power communication base station equipment of this utility model includes a protective shell 1, a threaded sleeve 2, an air inlet shroud 3, and a ventilation hole 22. A shell cover 11 is rotatably connected to one side of the outer wall of the protective shell 1. The outer wall of the shell cover 11 is welded with equidistant parallel heat dissipation fins 14. Equidistant parallel threaded holes 15 are opened inside the heat dissipation fins 14. A threaded sleeve 2 is threadedly connected inside the threaded holes 15. A support block 21 is interference-fitted to one side of the inner wall of the threaded sleeve 2. Assembly holes 23 are symmetrically opened on both sides of the outer wall of the support block 21. An air inlet shroud 3 is provided on both sides of the outer wall of the support block 21. A baffle plate 32 is welded to one side of the outer wall of the air inlet shroud 3. Guide rods 34 are welded to both sides of the outer wall of the baffle plate 32. A thermal expansion rubber strip 35 is glued and fixed to one end of the outer wall of the guide rod 34. A plug 31 is welded to one side of the inner wall of the air inlet shroud 3.

[0032] In use, the assembly holes 23 distributed on both sides of the support block 21 are arranged in a cross pattern. The necessary equipment for the communication base station is installed inside the protective shell 1 and the shell cover 11 for use. When the equipment heats up, the temperature of the equipment is transferred to the thermal expansion rubber strip 35 through the shell cover 11, the heat dissipation fins 14, the threaded sleeve 2, and the support block 21. The thermal expansion rubber strip 35 expands when heated and pushes the guide rod 34 and the air inlet shroud 3 to move until the plug 31 disengages from the ventilation hole 22. This, in conjunction with the ventilation hole 22, enables natural convection of air inside the heat dissipation fins 14, increasing the heat dissipation fins. The airflow trajectory on the outside of the heat sink 14 increases the heat dissipation area and efficiency of the heat sink 14. After the equipment temperature drops, the thermal expansion rubber strip 35 shrinks due to heat loss, causing the air inlet cover 3 to reset and the plug 31 to reset and seal the ventilation hole 22, reducing the entry of external dust into the ventilation hole 22 and ensuring the unobstructed flow of the ventilation hole 22 for the next use. This also allows for the adjustment of the airflow trajectory on the outside of the heat sink 14, thereby adjusting the heat dissipation efficiency of the heat sink 14 and ensuring that the equipment can adapt to different ambient temperatures and ensure the normal operation of the equipment.

[0033] For device protection, for example, such as Figure 1 As shown, antennas 12 are provided at equal intervals and parallelly distributed on the upper outer wall of the protective shell 1. Connectors 13 are symmetrically installed on the upper and lower outer walls of the protective shell 1 and the shell cover 11, and the protective shell 1 is connected to the shell cover 11 by screws through the connectors 13.

[0034] When in use, the equipment inside the protective shell 1 can transmit and receive signals through the antenna 12, and the connector 13 ensures the stability of the connection between the protective shell 1 and the cover 11, ensuring the protection of the equipment inside the protective shell 1 and the cover 11, and facilitating the disassembly and rotation of the cover 11, so that the staff can maintain the equipment inside the protective shell 1.

[0035] For heat dissipation, for example, such as Figure 3 As shown, the support block 21 has a ventilation hole 22 inside. Both sides of the inner wall of the ventilation hole 22 are designed with a conical shape, and the size of the ventilation hole 22 is adapted to the size of the plug 31.

[0036] During use, ambient air can flow and dissipate heat inside the heat dissipation fins 14 through the air inlet shroud 3 and the ventilation holes 22. The conical shape can ensure the airflow speed inside the ventilation holes 22 based on the septum effect, ensuring the convective heat dissipation effect. When the plug 31 is attached to the inner wall of the ventilation holes 22, it can block the ventilation holes 22, ensuring that the airflow is controlled and flows inside the ventilation holes 22.

[0037] To drive movement, for example, such as Figure 5As shown, the diameters of the guide rod 34 and the thermal expansion rubber strip 35 are both smaller than the inner diameter of the assembly hole 23, and both the guide rod 34 and the thermal expansion rubber strip 35 are located inside the assembly hole 23. The outer wall of the end of the thermal expansion rubber strip 35 away from the guide rod 34 is bonded and fixed to the inner wall of the assembly hole 23.

[0038] During use, the thermal expansion rubber strip 35 is bonded to the inner wall of the assembly hole 23 and the guide rod 34 at both ends, which ensures that the position of the thermal expansion rubber strip 35 is relatively stable. The guide rod 34 and the assembly hole 23 can limit the expansion direction of the thermal expansion rubber strip 35, ensuring that the expansion force of the thermal expansion rubber strip 35 is transmitted to the guide rod 34 axially, thus ensuring the driving accuracy of the air inlet hood 3. The thermal expansion rubber strip 35 can expand by 150%-300% in the temperature range of 60-120 degrees Celsius, ensuring that the moving distance of the air inlet hood 3 can adapt to the equipment temperature.

[0039] For inspection purposes, for example, such as Figure 4 As shown, a maintenance plate 24 is snapped onto one side of the inner wall of the assembly hole 23, and the maintenance plate 24 does not contact the thermal expansion rubber strip 35.

[0040] During use, staff can visually observe the thermal expansion rubber strip 35 through the assembly hole 23 by disassembling the inspection plate 24, thereby observing the condition of the thermal expansion rubber strip 35 and helping staff to replace the thermal expansion rubber strip 35 in a timely manner.

[0041] To block the vent 22, for example, such as Figure 5 As shown, the plug 31 adopts a conical shape design. The plug 31 is located inside the ventilation hole 22 and is in contact with the inner wall of the ventilation hole 22.

[0042] When in use, the conical shape makes it less likely for water to accumulate, preventing liquid from accumulating inside the ventilation hole 22, and the plug 31 can seal both ends of the ventilation hole 22.

[0043] For sealing purposes, exemplarily, such as Figure 5 As shown, a sealing ring 33 is bonded and fixed to the outer wall of the baffle plate 32, and the sealing ring 33 is in contact with the inner wall of the threaded sleeve 2.

[0044] During use, the sealing ring 33 ensures the seal between the baffle plate 32 and the threaded sleeve 2, ensuring that the flow trajectory of gas inside the ventilation hole 22 and the air inlet shroud 3 is controlled.

[0045] When this utility model is in use, during the initial operation of the equipment or when the ambient temperature is low, the thermal expansion rubber strip 35 is in a contracted state, the plug 31 is tightly attached to the inner wall of the ventilation hole 22, and the baffle 32 is sealed with the threaded sleeve 2 by the sealing ring 33 to prevent dust and moisture from entering the interior of the heat dissipation fins 14.

[0046] The equipment generates heat during operation. The heat is transferred to the support block 21 through the shell cover 11, heat dissipation fins 14, and threaded sleeve 2, and then conducted to the thermal expansion rubber strip 35. When the temperature rises to 60-120 degrees, the thermal expansion rubber strip 35 expands by 150%-300%. The thermal expansion rubber strip 35 pushes the guide rod 34 to move the air inlet cover 3, causing the plug 31 to disengage from the ventilation hole 22 and opening the ventilation channel.

[0047] When the ventilation hole 22 is opened, outside air enters through the air inlet shroud 3. The conical design of the inner wall of the ventilation hole 22 creates a narrow tube effect, accelerating airflow and enhancing natural convection. Air flows inside the heat dissipation fins 14, increasing the heat dissipation area and the contact time with the air.

[0048] After the equipment temperature drops, the thermal expansion rubber strip 35 shrinks due to heat loss, pulling the guide rod 34 to reset the air inlet hood 3, and the plug 31 re-seals the ventilation hole 22.

[0049] It should be noted that this utility model is a low-power communication base station device. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
