Outdoor base station heat dissipation, EMI scheme

The outer shell of the outdoor base station in the communication industry is usually die-cast cavity. Due to the high reliability requirement, passive heat dissipation is usually adopted to realize the heat dissipation of the whole machine. The heat generated by this equipment has exceeded 30W/L and reached 35W/L at a high level, which brings serious challenges to the heat dissipation of the whole machine. According to the heat transfer scheme of heat conduction fins, the heat conduction pad with high thermal conductivity coefficient can achieve significant heat dissipation effect. However, a difficult problem is that the heat resistance of some if devices in the cavity is low. Another problem is the difficulty of power amplifier heat dissipation.For the rf part, the ambient temperature is generally limited to 75℃, which becomes the bottleneck of system heat dissipation to some extent.

5G is fast? Huawei BBU heat dissipation using what advanced materials

图片
Recently, Huawei has been the center of the conversation because of the us government's blockade of Hwei. Huawei's dominance in the global communications industry is due to the core nature of its technology and its recognition by many countries. As early as 2013, Huawei has established communication base stations in more than 80 countries in the world, which accounts for a large share. Well, let's talk about the heat dissipation design of Huawei BBU (baseband pull-away unit). So let's see what BBU does. The functions of BBU(Bui lding Base band Unite) indoor baseband processing unit are to complete baseband processing functions of Uu interface (coding, multiplexing, modulation and spread spectrum, etc.), Iub interface functions of RNC, signaling processing, local and remote operation and maintenance functions, and work status monitoring and alarm information reporting functions of NodeB system. In the front, there are 6 SFP interfaces on the board, and

Mobile phone cooling, EMI solution

The main frequency of smartphone chips is getting higher and higher, which will generate a large amount of heat, which will affect users' comfort and may also burn out the hardware. At present, mobile phone manufacturers generally adopt two solutions to reduce the heat problem of mobile phones: one is hardware cooling, such as graphite cooling, and the other is kernel optimization cooling.The application of heat-conducting graphite is a relatively common one. The heat conductivity of graphite heat dissipation film is 2-4 times that of copper. It can provide better thermal conductivity while reducing the weight of devices.

Lori cooling keeps your electronics safe

The development of society is inseparable from science and technology, and the development of science and technology is inseparable from electronics.   Without the rise of the electronic industry, there would be no third industrial revolution that has lasted till now. Nowadays, electronic equipment has penetrated into all walks of life, and it has dominated the majority of production and life.   Moreover, it has seriously captured the freedom of human beings. We need computers for office work, televisions and mobile phones for leisure and entertainment. It seems that without it, human beings lose the ability to live independently. Electronic development is extremely rapid, and electronic equipment heat dissipation also experienced natural heat dissipation (passive heat dissipation) to air-cooled heat dissipation, and then to water-cooled heat dissipation, this is a period of exploration and summary of actual combat experience in the progress of electronic development.
