The 21st century can be a stage in which the development of human science and technology has exploded. All kinds of cross-age technologies and discoveries emerge endlessly. The earliest fixed telephone appeared in the 1860s. Still, it was not until the 1970s, a hundred years later, that the earliest portable telephones gradually appeared, and this kind of telephones gradually became popular in the 1990s 20 years later. In the blink of an eye, the timeline has come to 2021, just 20 years into the 21st century. Human technology has gradually eliminated multiple signal transmission methods. Mobile phones in the early 20th century have become antiques today. 5G technology is becoming popular in more and more countries, people's lives are gradually being accelerated by 5G, and we are increasingly inseparable from 5G networks. Imagine that Wall Street loses the Internet for one day. The consequences will be irreversible.
Everyone knows the law of conservation of mass when something is doing work. It inevitably emits heat so that engineers will equip them with the corresponding thermal cooling plate—especially products of the electronic component type. Due to complex circuits and various electronic components on the PCB circuit board, an electrical appliance emits a lot of heat when it is working. The 5G signal base station, as one of the most integrated devices today, emits more heat and electromagnetic fields than any base station in the past. And due to the improvement of technology, the 5G signal base station has dramatically reduced the volume while improving the performance. It means that its cooling plates for electronics should also be synchronized to improve heat dissipation efficiency and reduce volume. Thanks to the emergence of new materials such as polymers, engineers have been greatly helped. Although materials such as silica gel have a good heat dissipation effect, 5G base stations are built on open high places such as rooftops. It means that harsh natural conditions such as wind, sun, lightning, and rain also accompany it. Silica gel cannot be guaranteed to be effective for a long time under this condition. Therefore, engineers choose the formula of silica gel + copper cold plate to dissipate heat from 5G base stations. Copper material has good stability and can still play a role in electromagnetic and high-temperature environments. The copper plate also has a certain degree of corrosion resistance to rain erosion.
