The mobile phone cooling scheme has emerged, and the heat pipe and vapor chamber cooling technology are outstanding. Traditional heat conductive metal materials can not meet the requirements of high heat conductive efficiency. At present, the schemes of mobile phone heat dissipation are graphite sheet, graphene, vapor chamber, heat pipe and so on. The thermal conductivity of heat pipe and vapor chamber is higher than other schemes, and the advantages of thermal conductivity efficiency are outstanding. At the same time, the heat pipe and vapor chamber have long service life, and the temperature equalization effect is better than other heat dissipation schemes. Many 5G mobile phone manufacturers have started to adopt heat pipe and vapor chamber to dissipate heat. Wireless charging and OLED development will also increase the cooling demand.
