mobile phone thermal solution design
During the use of mobile phones, the heating of mobile phone body is a common problem that most mobile phone users need to face. Smart phones contain many components that can generate heat, and the components are damaged due to poor performance and use methods caused by heat. Among them, the processor is the main component that generates heat, Other components that can generate a lot of heat include lithium-ion battery, image sensor, light source, etc. most of the reasons for mobile phone heating are long mobile phone call time, downloading files, running game software or generating a lot of heat during charging. While mobile phone heating will lead to unstable mobile phone signal, stuck operation, accelerated circuit aging, weakened battery life and shortened service life And other problems, resulting in the reduction of user safety and comfort and economic losses in maintenance costs.
In recent years, with the stable development of intelligent technology, intelligent manufacturing has become the focus of many product R & D. promoting intelligent manufacturing technology can effectively improve the work efficiency of products and reduce their operation cost. Therefore, in terms of mobile phone heatsink, we can find some breakthrough points for upgrading, such as using specific devices to realize intelligent temperature control. After smart phones enter the 5g era, With the increasing use frequency of mobile phones, their accessories will bear greater use pressure. Therefore, we should try our best to eliminate the influence of external factors to prolong the service life of mobile phones.
Adding temperature sensor:
Wireless temperature sensor is a contact temperature sensor, which has the advantages of small volume, simple installation process and easy return to the factory for maintenance in case of problems. In addition, the transmission distance of wireless temperature sensor is not limited by distance. It can transmit the temperature data of mobile phone to the terminal in real time, and it is less likely to be disturbed by the external environment under short-distance data transmission, Easy to monitor, safe and reliable.
Cold clamp refrigeration system：
The cold clip cooler cools down quickly. In the laboratory environment, the cold clip system can reduce the high-temperature mobile phone of about 50 ℃ to about 20 ℃ within a few minutes through semiconductor technology, which can fully reduce the mobile phone temperature by nearly 30 ℃. Under the control of temperature, it can ensure that the mobile phone is not too cold, which is suitable for users who use the mobile phone for a long time, such as playing large-scale games, live broadcasting, etc
Centrifugal fan cooling:
The seven blade centrifugal fan can keep the mobile phone temperature at a relatively stable value under the environment of stable wind and low noise, so as to save the power of the heatsink itself.
According to the current development trend of the domestic mobile phone heatsink market, the demand of mobile phone users for heatsinks is gradually increasing. At the same time, the rigid requirements for the practicability of heatsinks are becoming higher and higher. The design of mobile phone intelligent radiator combining wireless temperature sensing technology and cold clip refrigeration system not only improves the heat dissipation efficiency, but also is convenient to carry and has weak noise. It can be applied to different times and various occasions. Therefore, the design and research of mobile phone intelligent heatsink is of great significance.
