Description

Technical Field

[0001] This utility model relates to the field of BBU vertical mounting cabinet technology, and more specifically, it relates to a BBU vertical mounting cabinet. Background Technology

[0002] A vertical BBU rack is a rack specifically designed to house battery backup units (BBUs). It is commonly used in data centers, server rooms, and communication networks to ensure critical equipment can continue operating during mains power outages. The main feature of this rack is that the BBU batteries are installed vertically, which saves space, improves thermal management efficiency, and facilitates battery maintenance and replacement.

[0003] In existing technologies, vertical BBU cabinets mainly achieve heat dissipation by installing cooling fans on the cabinet body to promote airflow within the cabinet. However, the fixed installation position of the cooling fans results in a fixed airflow direction into the cabinet body, which creates dead zones in airflow within the cabinet body, thus affecting the adequacy of airflow within the cabinet body and impacting the heat dissipation effect.

[0004] In addition, to prevent external dust from entering the cabinet, a filter is usually installed at the air inlet. However, dust and other substances can stick to the filter and need to be cleaned regularly. Otherwise, the filter will easily become clogged, affecting the air intake inside the cabinet and thus affecting the overall heat dissipation of the cabinet. Utility Model Content

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a vertically mounted BBU cabinet, which has the following advantages:

[0019] 1. Includes a cabinet. Multiple sets of air guide plates are rotatably mounted on the bottom of the cabinet via a bearing structure. A rotation drive structure is installed on the cabinet in conjunction with the air guide plates. This rotation drive structure includes a second motor located on the outside of the cabinet. Mounting shafts are mounted on the air guide plates, extending to the outside of the cabinet. A transmission connection is established between the motor and one of the mounting shafts. A synchronous belt structure is installed between adjacent sets of mounting shafts. Thus, during ventilation inside the cabinet, the second motor can be activated. Through the coordination of the second motor and the synchronous belt structure, the mounting shafts can be controlled to drive the air guide plates to rotate reciprocally, thereby guiding the airflow inside the cabinet, making the ventilation more uniform and sufficient, and improving the ventilation and heat dissipation effect inside the cabinet.

[0020] 2. This utility model has an air inlet at the bottom of the side wall of the cabinet, with a filter screen fitted at the air inlet. An exhaust fan is installed inside the air inlet, and an air outlet is installed at the top of the side wall of the cabinet, with a protective filter screen installed at the air outlet. During this process, under the action of the exhaust fan, airflow can enter the cabinet through the air inlet, flow upward, and be discharged outward through the air outlet, thereby realizing the circulation of airflow within the cabinet and achieving heat dissipation inside the cabinet. Here, the installation of the filter screen and the protective filter screen can prevent external dust and debris from entering the cabinet, improving the ventilation and cleanliness inside the cabinet.

[0021] 3. This utility model features a mounting frame on the outside of the cabinet. A cleaning brush is mounted on the mounting frame via bearings, and a first motor connected to the cleaning brush is also mounted on the mounting frame. A lifting drive structure is provided between the mounting frame and the cabinet. The lifting drive structure includes a fixed base mounted on the outer wall of the cabinet and located above the air inlet. An electric push rod is mounted on the fixed base, and the bottom end of the electric push rod is connected to the mounting frame. Thus, when the filter screen at the air inlet becomes clogged, the electric push rod can be activated. The electric push rod controls the lifting and lowering of the mounting frame, which in turn controls the lifting and lowering of the cleaning brush. Simultaneously, the first motor is activated, which controls the rotation of the cleaning brush. The cleaning brush cleans the filter screen, thereby improving the ventilation effect at the filter screen and enhancing the heat dissipation effect inside the cabinet.

[0022] 4. This utility model features a heat exchange mesh plate located below the air guide plate and above the exhaust fan. Heat-conducting plates are installed on both sides of the heat exchange mesh plate, which is embedded in the cabinet. A semiconductor cooling chip is attached to the outer side of the heat-conducting plate. During use, when the temperature inside the cabinet is high and natural airflow is insufficient to lower it, the semiconductor cooling chip can be activated. The chip cools the cabinet and transfers heat to the heat-conducting plate, allowing the low temperature to be transferred to the heat exchange mesh plate. The heat-conducting plate and heat exchange mesh plate are preferably made of aluminum or copper, which have good thermal conductivity. This allows the heat exchange mesh plate to cool down, thus enhancing the ventilation and cooling effect inside the cabinet when airflow passes over it. Attached Figure Description

[0034] Please see Figure 1-7 A vertically mounted BBU cabinet includes a cabinet body 1. Multiple sets of air guide plates 2 are rotatably mounted on the bottom interior of the cabinet body 1 via a bearing structure. A rotation drive structure is provided on the cabinet body 1 in conjunction with the air guide plates 2. The rotation drive structure includes a second motor 15 located on the outside of the cabinet body 1. Mounting shafts 16 are mounted on the air guide plates 2, extending to the outside of the cabinet body 1. A transmission connection is established between the air guide plate 15 and one of the mounting shafts 16. A synchronous belt structure 17 is provided between adjacent sets of mounting shafts 16. Thus, during ventilation inside the cabinet body 1, the second motor 15 can be activated. Through the coordination of the second motor 15 and the synchronous belt structure 17, the mounting shafts 16 can be controlled to drive the air guide plates 2 to rotate reciprocally, thereby guiding the airflow inside the cabinet body 1, making the ventilation inside the cabinet body 1 more uniform and sufficient, and improving the ventilation and heat dissipation effect inside the cabinet body 1.

[0035] This utility model has an air inlet 3 at the bottom of the side wall of the cabinet 1, a filter screen 4 is fitted at the air inlet 3, an exhaust fan 5 is installed inside the air inlet 3, and an air outlet 9 is installed at the top of the side wall of the cabinet 1. A protective filter screen 10 is installed at the air outlet 9. During this process, under the action of the exhaust fan 5, the airflow can enter the cabinet 1 through the air inlet 3 and flow upward, and be discharged outward through the air outlet 9, thereby realizing the circulation of airflow in the cabinet 1 and realizing heat dissipation inside the cabinet 1. Here, the filter screen 4 and the protective filter screen 10 can prevent external dust and debris from entering the cabinet 1, and improve the ventilation and cleanliness inside the cabinet 1.

[0036] This utility model features a mounting frame 6 on the outer side of the cabinet 1. A cleaning brush 7 is mounted on the mounting frame 6 via bearings, and a first motor 8 is mounted on the mounting frame 6 and driven by the cleaning brush 7. A lifting drive structure is provided between the mounting frame 6 and the cabinet 1. The lifting drive structure includes a fixed base 18 mounted on the outer wall of the cabinet 1 and located above the air inlet 3. An electric push rod 19 is mounted on the fixed base 18, and the bottom end of the electric push rod 19 is connected to the mounting frame 6. Thus, when the filter screen 4 at the air inlet 3 becomes clogged, the electric push rod 19 can be activated. The electric push rod 19 controls the lifting and lowering of the mounting frame 6, which in turn controls the lifting and lowering of the cleaning brush 7. Simultaneously, the first motor 8 is activated, which controls the rotation of the cleaning brush 7. The cleaning brush 7 cleans the filter screen 4, thereby improving the ventilation effect at the filter screen 4 and enhancing the heat dissipation effect inside the cabinet 1.

[0037] In this utility model, a heat exchange mesh plate 11 is provided below the air guide plate 2 and above the exhaust fan 5. Heat conduction plates 12 are provided on both sides of the heat exchange mesh plate 11. The heat conduction plates 12 are embedded in the cabinet 1, and a semiconductor cooling chip 13 is attached to the outside.

[0038] During use, when the temperature inside the cabinet 1 is high and it is difficult to lower the temperature through natural airflow, the semiconductor cooling chip 13 can be activated. The semiconductor cooling chip 13 cools the cabinet and transfers heat between itself and the heat-conducting plate 12, allowing the low temperature to be transferred to the heat exchange mesh plate 11 through the heat-conducting plate 12. The heat-conducting plate 12 and the heat exchange mesh plate 11 are preferably made of aluminum or copper with good thermal conductivity. This allows the heat exchange mesh plate 11 to be cooled. As a result, when airflow passes over the heat exchange mesh plate 11, it can be cooled, thereby enhancing the ventilation and cooling effect inside the cabinet 1.

[0039] Please see Figures 1-7 As one embodiment of the heat exchange mesh plate 11: the heat exchange mesh plate 11 is provided with a plurality of heat exchange fins 14.

[0040] Specifically, by setting the heat exchange fins 14, the heat exchange area between the heat exchange mesh plate 11 and the flowing air can be increased, thereby enhancing the cooling effect of the airflow.

[0041] Please see Figures 1-7 As one implementation of the filter screen 4: a retaining bracket 20 is provided on the outer side of the filter screen 4, and the retaining bracket 20 and the air inlet 3 are interlocked.

[0042] Specifically, the filter screen 4 can be detached and installed at the air inlet 3 through the clip 20, which makes it easy to replace the filter screen 4.

[0043] Please see Figures 1-7As one implementation of cabinet 1: a support leg 21 is provided at the bottom of cabinet 1, and a fixed foot 22 is provided at the bottom of the support leg 21.

[0044] The cabinet 1 can be stably supported by the cooperation of the supporting legs 21 and the fixed feet 22. At the same time, it can prevent the cabinet 1 from directly contacting the body surface, thereby improving the stability and cleanliness of the cabinet 1 during use.

[0045] Please see Figures 1-7 As one implementation of cabinet 1: a temperature sensor 23 is installed on the inner wall of cabinet 1.

[0046] The temperature sensor 23 is used to detect the temperature inside the cabinet 1, thereby facilitating the control of the operation of the thermoelectric cooler 13. Here, the temperature sensor 23 and the thermoelectric cooler 13 are controlled by a controller. The use of the controller and the wiring circuit diagram are existing known technologies, and will not be described in detail in this utility model.

[0047] In summary, when using the overall equipment:

[0048] When the exhaust fan 5 is turned on, the airflow will enter the cabinet 1 through the air inlet 3 and be transported upward. After circulating inside the cabinet 1, the air will be discharged outward through the air outlet 9 at the top, thereby taking away the heat inside the cabinet 1 and achieving heat dissipation and cooling inside the cabinet 1.

[0049] During this process, when the airflow passes through the air inlet 3, it will be filtered by the filter screen 4, thereby preventing external dust from entering the cabinet 1 and improving the ventilation and cleanliness inside the cabinet 1.

[0050] The temperature inside the cabinet 1 is monitored by the temperature sensor 23. When the temperature is high, the semiconductor cooling chip 13 can be activated to cool the cabinet and transfer heat between the semiconductor cooling chip 13 and the heat conduction plate 12. This allows the low temperature to be transferred to the heat exchange mesh plate 11 through the heat conduction plate 12. The heat conduction plate 12 and the heat exchange mesh plate 11 are preferably made of aluminum or copper with good thermal conductivity. This allows the heat exchange mesh plate 11 to be cooled down. When the airflow blows over the heat exchange mesh plate 11, it can be cooled down, thereby enhancing the ventilation and cooling effect inside the cabinet 1.

[0051] During this process, the second motor 15 is started. Through the coordination of the second motor 15 and the synchronous belt structure 17, the mounting shaft 16 can be controlled to drive the air guide plate 2 to rotate back and forth, thereby guiding the airflow inside the cabinet 1. This allows the airflow to continuously change direction as it flows inside the cabinet 1, making the ventilation inside the cabinet 1 more uniform and sufficient, and improving the ventilation and heat dissipation effect inside the cabinet 1.

[0052] When the filter screen 4 at the air inlet 3 needs cleaning, the electric push rod 19 is activated. The electric push rod 19 controls the raising and lowering of the mounting bracket 6, which in turn controls the raising and lowering of the cleaning brush 7. At the same time, the first motor 8 is activated, which controls the rotation of the cleaning brush 7. The cleaning brush 7 cleans the filter screen 4, thereby improving the ventilation effect at the filter screen 4 and enhancing the heat dissipation effect inside the cabinet 1.
