Description
Technical Field
[0001] This utility model relates to the technical field of gateway heat dissipation equipment, specifically a split-type 5G gateway heat dissipation mounting bracket. Background Technology
[0002] Existing outdoor split-type 5G gateways (RUs) are typically mounted directly on poles or walls, relying primarily on passive cooling from the device's own casing or small fans for heat dissipation. Especially during the summer months when rain and heat coincide, the built-in cooling systems often struggle to cope with the high temperatures, leading to a sharp decline in gateway efficiency and even overheating-induced shutdowns. Furthermore, outdoor environments are prone to clogging air intakes with dust, willow catkins, and insects, further exacerbating overheating.
[0003] The efficiency of the cooling network can be improved by increasing the size of the cooling fan and the power of the cooling fan motor, but these measures will undoubtedly increase the overall cooling energy consumption, which will undoubtedly increase the operating costs of equipment used continuously for a long time. Utility Model Content

The bottom of the cylindrical outer shell has a bottom hole, and the top of the cylindrical outer shell has a top hole. The top hole is equipped with a wind speed increasing and exhaust device. The wind speed increasing and exhaust device is used to increase the wind speed inside the cylindrical outer shell by utilizing external wind power, thereby improving the heat dissipation rate of the gateway device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example
[0019] The following is combined with Figure 1 and Figure 2 This application introduces a split-type 5G gateway heat dissipation mounting bracket, including a cylindrical shell 1, a fixing connector 10, a waist hole 2, a horizontal heat dissipation channel 3, and a wind-powered air extraction device.
[0020] The cylindrical outer shell 1 has a fixed connector 10 on its side for connection to a support pole or wall. A waist hole 2 penetrating the outer wall is opened on the middle side of the cylindrical outer shell 1, and the waist hole 2 connects to a horizontal heat dissipation channel 3. The horizontal heat dissipation channel 3 communicates with the heat dissipation holes of the gateway device. It is worth noting that the gateway device can be connected to the horizontal heat dissipation channel 3 using various structures such as clamps, threads, snaps, and tenons. If there are gaps at the connection points, sealant or expanding foam can be used for sealing. This ensures safety by preventing foreign objects and increases airflow, thereby improving heat dissipation efficiency. The bottom of the cylindrical outer shell 1 has a bottom hole 4, and the top of the cylindrical outer shell 1 has a top hole 5. A wind-powered air extraction device is installed in the top hole 5. This wind-powered air extraction device uses external wind to increase the airflow speed inside the cylindrical outer shell 1, thereby improving the heat dissipation rate of the gateway device. Utilizing natural wind to increase the airflow speed in the horizontal channel improves heat dissipation efficiency without additional energy consumption. The cylindrical outer shell 1 physically isolates the gateway device from lateral dust and insect intrusion.
[0021] In a preferred embodiment, the wind-driven air extraction device includes a wind turbine impeller 8, an axial flow impeller 9, and a support 7. The support 7 is mounted on the top hole 5, and the wind turbine impeller 8, which absorbs wind energy, is rotatably mounted on the support 7. The axial flow impeller 9 is rotatably mounted inside the cylindrical outer shell 1. The wind turbine impeller 8 drives the axial flow impeller 9 to rotate via a transmission structure, creating an upward airflow. This two-stage ventilation from the wind turbine impeller 8 to the axial flow impeller 9 creates a stable airflow acceleration effect within the cylindrical outer shell 1, forming a stable and efficient cooling airflow, enhancing the chimney effect within the cylindrical outer shell 1, and improving heat dissipation efficiency. To reduce weight, the cylindrical outer shell 1 is preferably made of aluminum alloy or polymer material, ensuring outdoor durability, reducing costs, and increasing thermal conductivity.
[0022] The wind turbine impeller 8 is preferably a vertical axis impeller. Compared to a horizontal axis impeller, a vertical axis impeller can adapt to 360° random wind direction, increasing wind energy utilization by more than 50%, and allowing for year-round wind energy utilization. The wind turbine impeller 8 and the axial flow impeller 9 are coaxially arranged and fixedly connected by a connecting shaft. This direct mechanical connection structure reduces the failure rate. Of course, if necessary, a transmission structure with a reduction ratio can be used, such as gear drive, belt drive, or chain drive. The vertical axis impeller can be an H-type vertical axis impeller, using polymer or carbon fiber materials to reduce weight.
[0023] A flared section 6 is installed on the top hole 5. The flared section 6 can be combined with the cylindrical outer shell 1 by welding, riveting, threaded connection or sheet metal integral molding. The flared section 6 has a trumpet-shaped structure that is smaller at the bottom and larger at the top, forming a jet effect. According to the Laval effect, the airflow velocity of the flared section 6 is accelerated, further enhancing the chimney effect in the cylindrical outer shell 1 and improving heat dissipation efficiency.
[0024] In some embodiments, the inner wall of the cylindrical outer shell 1 is provided with a water-blocking strip 12 along the edge of the waist hole 2 to prevent rainwater from entering the horizontal heat dissipation channel 3. The water-blocking strip 12 can be made of vulcanized rubber. When the size of the water-blocking strip 12 is 8-10mm, it can block 99% of splashed rainwater from entering the horizontal heat dissipation channel 3.
[0025] In an optional optimized solution: a bottom filter 11, preferably a 1mm aperture stainless steel mesh, is provided along the bottom hole 4 on the inner wall of the cylindrical outer shell 1. This filter is used to intercept willow catkins and insects from entering the horizontal heat dissipation channel 3. Since the airflow direction is from bottom to top, even willow catkins and insects adhering to the bottom filter 11 will automatically fall off due to gravity or rainwater washing, thus achieving self-cleaning. It is worth mentioning that the bottom filter 11 can be connected to the cylindrical outer shell 1 by a snap-on or threaded connection, accelerating the efficiency of cleaning and maintenance.
[0026] Optionally, the direction can be optimized. A mechanical speed limiter is installed on the bracket 7 to prevent the speed of the wind turbine 8 from exceeding the limit. In typhoon areas or other areas with high wind speed, it is necessary to add a mechanical speed limiter to limit the speed when the speed exceeds the set value and protect the equipment. The mechanical speed limiter can also use the centrifugal force when the speed is too high to make the centrifugal block expand outward and decelerate by friction with the cylindrical shell 1.
[0027] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
