Description

Technical Field

[0001] The utility model relates to the technical field of multi-connection cabinets, in particular to a multi-connection cabinet for a mobile communication outdoor base station. Background Art

[0002] With the rapid development of my country's communications industry, especially the large-scale application of 5G, the number of mobile communication base stations has shown a substantial growth trend, and there are still a large number of 3G and 4G stock base stations. As an outdoor base station for mobile communication access network, the power consumption is very huge. The power consumption of the air-conditioning equipment installed to ensure the stable operation of the communication equipment in the cabinet accounts for 10% or even more of the power consumption of the entire cabinet base station. Moreover, as the 3G and 4G in the original cabinet are upgraded to 5G equipment, the heat generation further increases, and higher requirements are placed on the cooling capacity of the original air-conditioning equipment. Most of the existing multi-connected cabinets use natural ventilation equipment to achieve temperature regulation, mainly installing exhaust fans to directly use fresh air outside the cabinet to cool the cabinet. Although natural ventilation can play a certain cooling role, the air outside the cabinet directly enters the cabinet, causing the dust cleanliness in the cabinet to seriously exceed the standard, and water vapor will bring safety hazards to the operation of communication equipment. Condensation water generated when the temperature changes may even cause damage to electrical equipment. Utility Model Content

[0016] Reference Figure 1-3 The utility model proposes a multi-connection cabinet for a mobile communication outdoor base station, comprising: a multi-connection cabinet body 1, the multi-connection cabinet body 1 comprises a plurality of connected sub-cabinets 6 and a connecting chamber 3, a grille plate 5 is installed between the connecting chamber 3 and the sub-cabinet 6, a driving mechanism 2 is installed on one side of the connecting chamber 3, the driving mechanism 2 is located inside the connecting chamber 3 and is connected to a transmission shaft 8, a plurality of groups of spiral sheets 9 are arranged on the transmission shaft 8, the plurality of groups of spiral sheets 9 are distributed one by one with a plurality of connected sub-cabinets 6, and ventilation holes 7 are opened between the plurality of connected sub-cabinets 6 to allow the air inside the multi-connection cabinet body 1 to circulate.

[0017] In this embodiment, the connecting chamber 3 is set to facilitate air exchange between multiple connected sub-cabinets 6. When the temperature of a sub-cabinet 6 is too high, temperature control is achieved by accelerating the air exchange between the multiple connected sub-cabinets 6 to avoid safety hazards caused by local overtemperature.

[0018] In this embodiment, the grid plate 5 is set to prevent the sub-cabinet 6 from directly contacting the communicating chamber 3, thereby playing a certain insulating role.

[0019] In this embodiment, the combination setting of the transmission shaft 8, multiple groups of spiral blades 9 and the driving mechanism 2 is to drive the transmission shaft 8 through the driving mechanism 2 to drive the multiple groups of spiral blades 9 to rotate, stir the internal air of the multiple connected sub-cabinets 6 to achieve air exchange between the multiple connected sub-cabinets 6, thereby achieving temperature control of the sub-cabinets 6, avoiding the inhalation of dust into the cabinet due to external equipment, and facilitating autonomous cooling in combination with the temperature control system.

[0020] In this embodiment, the ventilation opening 7 is provided to facilitate the internal circulation of air between the multiple cabinets 6 .

[0021] Specifically, Figure 3 As shown, the spiral distribution density of multiple groups of spiral sheets 9 is different, and the spiral directions of two adjacent groups of spiral sheets 9 are opposite. In this embodiment, such a distribution setting is to facilitate the temperature control requirements of different cabinets 6. For large temperature changes, spiral sheets 9 with large density distribution can be set to accelerate heat exchange. At the same time, the opposite setting facilitates heat exchange in different directions and improves the efficiency of heat exchange.

[0022] Specifically, Figure 3 As shown, the communication chamber 3 is arranged above a plurality of connected sub-cabinets 6 , and a grid plate 5 for communicating with the communication chamber 3 is installed on the top of the sub-cabinet 6 .

[0023] Specifically, Figure 3 As shown, the multiple groups of spiral sheets 9 are specifically spiral ceramic sheets.

[0024] In this embodiment, spiral ceramic sheets are used because ceramics have good thermal conductivity and ceramics themselves also have the function of absorbing heat, which is convenient for improving heat exchange efficiency and helps local cooling.

[0025] Specifically, Figure 1 As shown, a cabinet door 4 is installed at the front end of the sub-cabinet 6.

[0026] Specifically, Figure 1 and Figure 2 As shown, the driving mechanism 2 is specifically a motor. In this embodiment, the motor is used because the motor is easy to drive and operate, and is easy to access the control system to start automatically, saving time and effort.

[0027] In this embodiment, a phase change heat pipe heat exchanger can also be installed inside the communicating chamber 3 to utilize the natural low-temperature cold source in the environment to perform heat exchange with the high-temperature air in the cabinet to take away the heat in the cabinet.

[0028] During the specific working process of the mobile communication outdoor base station multi-connection cabinet of this embodiment, when the temperature of a certain cabinet 6 is too high, the driving mechanism 2 is started, and the driving mechanism 2 drives the transmission shaft 8 to drive the multiple sets of spiral blades 9 to rotate. The multiple sets of spiral blades 9 stir the air of the multiple cabinets 6 during the rotation. The multiple cabinets 6 exchange heat with the connecting chamber 3 through the grille plate 5, and local temperature control is achieved by circulating and consuming heat internally.
