5G base station heat sink
Reliability design is an important design link in communication system design, and the heat dissipation effect of equipment, especially the heat dissipation design of high power equipment, has a crucial influence on the reliability of equipment.
Michael o 'hara, chief marketing officer of the GSMA, a mobile trade group, said: "when data is moving at these very high speeds, the distances have to be reduced, so people have to have more antennas and data centres at the point of content acquisition.Basically every data lamppost has to have an antenna."In other words, the data channel must get shorter as it gets wider.
Base station is a radio transceiver that transmits information between the terminal and the mobile communication exchange center in a certain radio coverage area. It is important information hub of the wireless communication system. At present, base station is developing in the direction of large capacity, high power and high integration, and the heat dissipation per unit volume is also increasing, while the volume is getting smaller. The thermal design of base station has become an increasingly important problem in the design of base station complete machine. Normally, when the temperature exceeds a certain value, the failure rate of electronic devices increases exponentially with the increase of temperature.Improper cooling system is one of the main reasons for the decrease of the reliability of the electronic devices. 20% of the failures of electronic devices are caused by high temperature. Nowadays, the arrival of 5G requires more powerful severs to support the successful information transmission. 5G network signals have higher reliability and lower delay, which can meet the specific needs of intelligent manufacturing, automatic driving and other industries. For 5G network infrastructure construction pattern to transform to the intensive, miniaturization, intelligent, traditional large base stations have been difficult to meet the demand of the construction of the 5G base station. Base station heat sink must keep cool in the operation process, multiple fever semiconductor components such as CPU, chips must be closely together to achieve the best electrical properties, but also to cooling under this compact configuration. The high capacity 5G base station market favors low cost and high heat dissipation requirements, requiring the use of heat sinks,cooling devices,heat pipes or thermal interface materials(TIM), rather than using liquids that require electricity or forced liquids. LORI is able to dissipate these high heat fluxes using heat pipes with high thermal conductivity, providing a safe operating environment.
