With the continuous development of modern communication technology, the power density of electronic and communication devices is increasing, resulting in a sharp rise in device temperature. The working life and performance of the equipment are closely related to temperature. The thermal management of electronic and communication devices faces enormous challenges. How to solve the heat dissipation problem in limited device space, how to control the junction temperature of components within the allowable range, and how to ensure that the noise of the fan does not exceed the limit? Should we choose air cooling or water cooling?

As the "heart" of communication systems, 5G communication power determines the reliability of the entire system. In order to reduce and maintain cost benefits, improving the heat dissipation, thermal conductivity, and reliability of communication power is one of the main requirements of 5G communication power. For communication data, most 5G communication devices are built by expanding existing equipment. However, the energy space left for the 5G communication power cabinet is often limited, and even the original power cabinet can only be used. In these cases, the huge output power of the power supply needs to be significantly increased, which requires the communication power module, also known as the rectifier module, to increase the output power significantly while maintaining the basic volume, that is, to improve the power density.

However, due to the increase in power density, the heat dissipation and insulation of power electronics have become bottlenecks. Usually, the power components of communication power supplies generate severe heat, so they need to be cooled through an aluminum casing. Thermal conductive insulating sheet and thermal conductive gel can be well used in communication power supply to help solve the heat dissipation problem.

In 5G communication, the number of small base stations will increase significantly, and the power supply for most of these small base stations will be installed in enclosed spaces. Therefore, this type of communication power supply intelligently adopts natural heat dissipation methods, and suitable heat dissipation solutions can be selected according to actual applications.
