The 5G network era has arrived, and the majority of mobile phone manufacturers have launched new 5G mobile phones in turn. Compared with traditional 4G mobile phones, its energy consumption and power consumption will be greatly increased, which is 2.5 times that of the current 4G network era. At the same time, the heat generation of 5G mobile phones has also increased exponentially. The heat of the mobile phone will reduce the processing speed of the mobile phone, so the heat dissipation of 5G mobile phones has also become a key and difficult point for the majority of mobile phone manufacturers.
Micro heat pipe
Traditional mobile phone heat dissipation is mainly based on graphite heat dissipation, and liquid-cooled and air-cooled heat dissipation are also available. Recently, liquid-cooled heat dissipation is very popular. At present, many mobile phones are equipped with liquid-cooled heat dissipation pipes for heat dissipation.
The liquid cooling of mobile phones relies on a component called "micro heat pipe", which is essentially a hollow closed pipe containing liquid (usually high-purity purified water). The liquid evaporates and absorbs heat in the evaporation section of the pipe to become a gas. The condensing section of the pipeline condenses into liquid and releases heat. In addition, there is a liquid absorbing material that assists the liquid to return to the evaporation section to absorb heat.
The micro heat pipe is composed of a sealed container, a capillary structure and a working fluid. After the container is evacuated, an appropriate amount of working fluid is poured into it, and then sealed. The liquid injection hole of the micro heat pipe is small, and the caliber is as low as 0.15mm*0.15mm. The micro heat pipe has a small injection volume (as low as 0.025ml); the injection accuracy requires high (0.5%). After the liquid injection is completed, the sealing needs to be completed under vacuum.
Vacuum injection system
Guangzhou Ascend Precision Machinery Co., Ltd. is the first to develop a high-vacuum liquid injection system. It is composed of a precision ceramic pump system and a high vacuum valve. Guangzhou Ascend has provided customers with on-site batch vacuum injection solutions (0 to -85kpa) since 2016. Up to now, liquid injection can be performed under vacuum conditions of -95kpa. After customer site verification, it is drip-proof, accurate and accurate. The cpk value continues to be accurate and stable.
