Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment infrastructure, in particular to a BBU special cabinet. Background Art

[0002] Compared with 4G, 5G networks have faster Internet access speeds, lower latency, and can achieve multiple connections at the same time. However, due to the high spectrum, 5G requires the deployment of more base stations and denser sites. Dense deployment of base stations is a big challenge for site selection. Currently, the centralized deployment and stacking of BBUs can reduce the investment in new equipment rooms and achieve rapid deployment.

[0003] 5G networks have the advantages of high speed, low latency, and a large number of connections, and can meet the needs of various emerging businesses. However, as the number and types of 5G base stations continue to increase, problems in equipment layout, routing, heat dissipation, and power supply in base station rooms have gradually become prominent. The root cause is that dense deployment of base stations is a difficult problem for site selection. Although the currently used BBU centralized deployment and stacking method meets the characteristics of low investment, rapid deployment, and concentrated convergence, it is prone to "three highs" in the room, namely, high integration of the room, high local heat density, and high energy consumption.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting an air inlet device on the shell to take in air, and by setting a control component to control the opening and closing of the air inlet device, the cold air circulation in the first accommodation space in the shell can be realized, and by setting an exhaust device, the hot air inside can be discharged through the exhaust device to realize internal cooling. Also, by setting a refrigeration device in the first accommodation space, the first accommodation space can be actively cooled by the refrigeration device, so that the internal cooling efficiency is higher, and the internal equipment is prevented from overheating. At the same time, by setting a vertical plug-in frame installation component to install the BBU equipment, the air inlet of the BBU equipment is adjusted, so that the heat dissipation of the BBU equipment is better, and the energy consumption of the BBU equipment is reduced. Finally, through the opening and closing of the air inlet device and the cooperation of the refrigeration device, when the external temperature is low, the external cold source is used for cooling, and the refrigeration device does not need to be turned on. When the external cold source is not enough to support the cooling requirements of the internal equipment, the air inlet device is closed and the refrigeration device is turned on at the same time, which not only enhances the sealing of the front of the cabinet, but also makes the refrigeration efficiency of the internal refrigeration device higher, ensuring the internal refrigeration needs.

[0011] In an example of the utility model, the second air inlet assembly further includes: a guide member, which is arranged obliquely; and a protective member, which is arranged on a side close to the guide member.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by arranging the second air inlet assembly with a guide member, and the guide member is arranged at an angle, so that the second air inlet assembly can blow the wind in a directed manner into the internal components after receiving the wind from the first air inlet assembly, so as to perform targeted heat dissipation, thereby making the heat dissipation effect of the internal equipment better and ensuring the normal operation of the internal equipment. At the same time, by arranging a protective member close to the side of the guide member, the components inside the air inlet device can be reached through the protective member, thereby extending the working life of the internal components.

[0013] In an example of the utility model, a display unit is provided on the front door (1), and the display unit is used to display parameters and control a BBU dedicated cabinet.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting a display component to display parameters and control the cabinet, the parameters of the internal components can be intuitively seen through the display component, making daily inspections of the cabinet more convenient and intuitive, and improving the control over the interior of the cabinet.

[0038] Specifically, the air inlet device and the air exhaust device 10 are both provided with constant flow fans for exhausting air.

When the temperature detected by the internal temperature detection device is higher than the external temperature, the first power member 16 is started to drive the rotating assembly 18 to rotate. The first power member 16 can be a motor, and the rotating assembly 18 can be a rotating sealing plate. The air inlet channel is opened by rotating the sealing plate to achieve external switching of the cooling source. On the contrary, the rotating sealing plate is rotated to cover the air inlet channel, and the internal refrigeration device 12 is turned on at the same time. The refrigeration device 12 can be a rack-mounted air conditioner. After the air conditioner is started, the constant flow fan sends the cold source outside the cabinet to the cold channel area inside the cabinet through the filter net for the equipment to perform heat exchange, thereby achieving internal cold source refrigeration.

The original left air inlet is adjusted to a bottom air inlet, and a 3U air inlet space is set at the bottom of the air inlet to guide the cold air flow through the 19-inch front to the BBU air inlet, thereby changing the original airflow structure, so that the BBU device can also be installed on a standard 19-inch rack and compatible with conventional rack-mounted air conditioning and cooling. An auxiliary heat dissipation fan is installed at the top heat dissipation outlet to increase the negative pressure, so that the exhaust outlet avoids abnormal heat accumulation. At the same time, cable management troughs are added at the upper and lower positions on the front of the device for the optical fiber and grounding wiring of the BBU device. A standard blind plate can be installed on the installation frame of a single BBU device to flexibly adjust the number of devices.

Finally, through the opening and closing of the air inlet device and the cooperation of the refrigeration device 12, when the external temperature is low, an external cold source is used for cooling, and the refrigeration device 12 does not need to be turned on. When the external cold source is not enough to support the cooling requirements of the internal equipment, the air inlet device is closed and the refrigeration device 12 is turned on at the same time, which not only enhances the sealing of the front of the cabinet, but also makes the refrigeration efficiency of the internal refrigeration device 12 higher, ensuring the internal refrigeration needs.
