How does the TIM solve the thermal problem of 5G communication power supply
As the "heart" of the communication system, the 5G communication power supply determines the reliability of the entire system. In order to reduce and maintain cost benefits, improving the heat dissipation and reliability of the communication power supply is one of the main requirements of the 5G communication power supply.
For communication data, most of the existing equipment expansion methods are used to build 5G communication equipment. The power 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 output power of the power cabinet needs to be significantly increased, which requires the communication power module, also known as the rectifier module, to significantly increase the output power while maintaining the basic volume unchanged, That is, an increase in power density.
However, due to the increase in power density of the power supply, the heat dissipation and insulation of power electronics have become bottlenecks. Usually, the power components of communication power supplies generate severe heat, so it is necessary to use an aluminum shell for heat dissipation. Thermal conductive insulating sheet and thermal conductive gel can be well used in communication power supply to help solve the heat dissipation problem.
Benefits:
1. Low thermal impedance;
2. Good thermal conductivity;
3. Soft, no pressure between components;
4. Easily used for automated operation of dispensing systems;
5. Complies with UL94V0 fire rating;
6. Long term reliability.
Applications:
Widely used in the bottom or frame of heat sinks, LED LCD backlight tubes, LED televisions, LED lamps, high-speed hard drives, micro heat pipe heat sinks, automotive engine control devices, communication hardware, semiconductor automatic testing equipment and other products.
In 5G communication, the number of micro base stations will significantly increase, and the vast majority of the power supply for these micro base stations will be installed in enclosed spaces. Therefore, this type of communication power supply intelligently adopts natural heat dissipation, and suitable thermal conductive interface materials can be selected based on actual applications.
