Problems solved by technology

In the original technology, the BBU devices are all horizontally stacked and installed on a 19-inch rack. However, the heat dissipation methods of the original 5G BBU cabinets are mostly left-in, right-out, right-in, left-out, or forward-back-out. Inside the cabinet, the hot and cold airflow inside the cabinet is mixed, which cannot dissipate heat in time, forming a heat island effect, which often leads to high temperature alarms for equipment

Embodiment 1

[0039] The first intelligent indoor fresh air cooling operation mode can be selected when the indoor air environment is good, such as Figure 12 Shown:

[0040] In the intelligent indoor fresh air cooling operation mode, the intelligent air control system of the BBU cabinet detects that the temperature meets the indoor fresh air quality standard through the indoor fresh air temperature sensing device at the bottom of the front door. The fan in the air intake duct at the bottom is sucked into the front cooling cavity of the BBU cabinet. In the cabinet, the cold air enters the middle equipment chamber from the front cold chamber, passes through the heat dissipation unit to dissipate heat for the BBU equipment, and the hot air discharged from the middle equipment chamber enters the rear hot chamber, and is exhausted from the BBU cabinet through the rear air duct on the top of the cabinet to realize the heat dissipation of the 5G BBU equipment . At this time, the air inlet fan o...

Embodiment 2

[0044] The second intelligent air conditioner internal circulation heat dissipation operation mode can be selected when the indoor air environment is poor, such as Figure 13 Shown:

[0045] In the intelligent air conditioner internal circulation heat dissipation mode, the rack-mounted precision air conditioner in the lower part of the BBU cabinet works to provide cold air to the BBU cabinet. The fans in the rear exhaust air duct on the top of the BBU cabinet do not work, the air intake duct at the bottom of the front door of the BBU cabinet, the air intake duct on the top of the BBU cabinet, and the exhaust air duct on the top of the BBU cabinet are all closed. The cold air enters the front cooling chamber, and the cold air enters the middle equipment chamber from the front cold chamber, and then passes through the heat dissipation unit to dissipate heat for the BBU equipment. The hot air discharged from the middle equipment chamber is discharged into the rear hot chamber, an...

Embodiment 3

[0047] The third intelligent outdoor fresh air heat dissipation operation mode can be properly selected according to the local outdoor air conditions. This operation mode is more energy-saving, such as Figure 14 Shown:

[0048] The front air duct at the top of the cabinet is directly connected to the outside through the directly connected outdoor air inlet pipe 35 and the directly connected outdoor air inlet pipe filter screen 34 to introduce outdoor fresh air. The air duct at the rear of the top of the cabinet is directly connected to the outside through the direct-connected outdoor exhaust duct 36 and the filter screen 37 of the direct-connected outdoor exhaust duct to discharge the hot air to the outside; indoors.

[0049] In the intelligent outdoor fresh air cooling operation mode, the front air duct on the top of the BBU cabinet is directly connected to the outside through pipes and filters, and the outdoor air is collected. From the air duct on the top of the BBU cabi...

Abstract

An intelligent heat dissipation BBU cabinet is characterized in that a front door and a rear door are respectively arranged at the front and the rear of a cabinet body, and the cabinet body is internally divided into a front cooling cavity, a middle equipment cavity and a rear heating cavity. The front cooling cavity is a cold air channel, equipment needing heat dissipation is arranged in the middle equipment cavity, and the rear heating cavity is a hot air channel for exhausting hot air of the equipment. Aiming at a 5G BBU cabinet of a high-energy-consumption base station, a more reasonable airflow distribution mode is provided, and a front cooling cavity, a middle equipment cavity, a rear heating cavity, three cavities and cold and heat separation are achieved; the heating sources BBU are separated by the BBU cold air pool, and the heating sources in the cabinet are also separated from each other, so that accurate air supply is realized, the local heat island effect in the cabinet is eliminated, and the high-temperature alarm is eliminated; and the intelligent indoor fresh air heat dissipation operation mode or the intelligent air conditioner internal circulation heat dissipation operation mode or the intelligent outdoor fresh air heat dissipation operation mode can be selected according to self requirements, the use environment is wider, and the installation and use requirements of 5G BBU equipment are better met.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an intelligent cooling BBU cabinet. Background technique [0002] With the rapid development of 5G technology in my country's mobile communication system, the power consumption of 5G BBU equipment is increasing. 5GBBU equipment generates a lot of heat when it is working, and it needs to be cooled quickly and effectively to work normally. In the original technology, the BBU devices are all horizontally stacked and installed on a 19-inch rack. However, the heat dissipation methods of the original 5G BBU cabinets are mostly left-in and right-out, right-in and left-out, or forward-back-out. Inside the cabinet, the hot and cold airflow inside the cabinet is mixed, which cannot dissipate heat in time, forming a heat island effect, which often causes high temperature alarms for equipment. Contents of the invention [0003] The purpose of the present invention is to provide a t...
