5G base station heat dissipation system for realizing cellular network relocation

Abstract

The invention relates to a 5G base station heat dissipation system for realizing cellular network relocation. The AAU equipment is divided into a plurality of reasonably-arranged L-shaped heat dissipation channels through heat insulation plates, and all heating elements are installed in the heat dissipation channels, so uniform heat dissipation of all the heating elements is achieved; a double-layer heat insulation structure is arranged on one adjacent side face of the box body, so that the side face directly faces the direction with large solar radiation heat, and the influence of solar radiation on the temperature rise in the box body is reduced as much as possible; cold air is generated through the refrigeration module with the semiconductor refrigeration piece as the core, the cold air is blown into the heat dissipation channels through the air inlet fans corresponding to the heat dissipation channels in a one-to-one mode so that the purpose of rapidly cooling the heating element can be achieved, and heat can be discharged in time. Therefore, efficient heat dissipation, effective heat insulation and uniform heat dissipation of the AAU equipment can be realized by improving the box body structure of the AAU equipment and arrangement of internal electronic components and adding the refrigeration module.

Description

technical field [0001] The invention relates to a 5G base station cooling system for realizing cellular network relocation. Background technique [0002] With the vigorous development of applications such as 4K / 8K, VR / AR, autonomous driving, robots, and video surveillance, the era of 5G-based intelligent connection of all things has arrived, and the premise of massive data must be greater energy consumption. Consumption is the main factor. Compared with 4G base stations, the power consumption of 5G base stations is about 3-4 times that of 4G base stations. Due to the small coverage of 5G base stations, within the same coverage area, the power consumption of 5G base stations is 9-9 times that of 4G. 10 times. Therefore, some experts predict that by 2025, the communication industry will consume 20% of the world's electricity. So much power consumption is bound to generate a lot of heat. [0003] At present, the main energy consumption of 5G base stations is concentrated in ...

Problems solved by technology

[0006] However, in the prior art, due to the limitation of the installation location for the AAU with higher heat generation, the traditional natural heat dissipation can only be adopted. AAU generally includes a metal box and a radio frequency unit, antenna and processing unit located in the box. In the 5G era , AAU supporting Massive MIMO (large-scale multiple-input multiple-output) technology has become the mainstream, namely

However, at present, this type of AAU is generally installed on the leased iron tower, and its installation position is relatively high, and the radio frequency unit in the box generates a large amount of heat. If the heat cannot be dissipated or the heat is dissipated slowly, the temperature in the box will rise, which will affect the internal environment. The normal operation of electronic components and reduce the life of electronic components

In addition, for high-temperature areas such as Northwest China, the sun will cause the temperature of the box to rise rapidly, and this part of the heat will also be transferred to the internal electronic components through the box, further increasing the loss and damage of electronic components.

On the other hand, in the prior art, there is also a solution to accelerate the heat dissipation inside the box by blowing air into the box, but because the number of radio frequency units inside the AAU is large and densely arranged, and the fan is generally set in one position, As a result, the internal airflow only flows on the nearest channel, and the heating elements far away from the airflow channel or hidden in the corner area cannot be dissipated quickly and effectively, that is, the heat dissipation in the box is uneven, and the AAU still has the risk of damage
