How to dissipate heat in 5G base stations

5G technology is constantly developing and popularizing. The 5G communication base station equipment is developing in the direction of lightweight and high power. The heat consumption density of the system is increasing, but the volume is decreasing. Due to high-reliability requirements, passive heat dissipation is usually used to realize the heat dissipation of the whole machine.

As 5G base stations generate more heat, the difficulty of temperature control is also rising. The power consumption of a 5G base station is 2.5 to 4 times that of a 4G base station, which is mainly generated by the AAU and BBU performing the signal conversion, processing, and transmission. The rise in base station power consumption means an increase in heat generation.

5G base stations are usually installed on iron frames on the roofs of buildings and high places in the field. Therefore, reducing the size and weight of the equipment is essential for the convenience of installation. It will inevitably bring more significant challenges to the heat dissipation of 5G base stations. To better solve the heat dissipation problem of 5G base stations. It is required to improve the heat exchange efficiency of the base station as much as possible and reduce the heat transfer resistance in a limited space.

Thermally conductive silicone sheet and copper heat sink can well solve the reliability and electromagnetic compatibility problems of equipment and devices such as AAU, RRU, and base station cabinets in communication base stations in complex environments. In addition, the copper material has good stability and can work typically in an electromagnetic environment. Not only 5G base stations but most of the Server Heat Sink and IGBT heat sink is also composed of Copper heat sink and other heat conduction modules. But this places great demands on the accuracy of the Copper heat sink.

Because the copper heat sink is made of metal, materials such as silica gel thermal pads are softer in texture. A slight dimensional deviation under high-temperature working conditions may cause damage to other heat dissipation modules. The damage to the cooling module will directly cause the expensive servers and base stations to be overloaded and burned. Therefore, KINGKA uses high-precision 5 axis CNC machining to process Passive Heat Sink to ensure that the accuracy of the parts is qualified.
