In the 21st century, mobile phones have become a very common communication tool. Even now, many people still get "mobile phone sickness", holding their mobile phones for 20 hours 24 hours a day. With the rapid development of mobile phones, many mobile phone accessories have been derived. Mobile power is one of them, also called power banks. . The power bank is very light and can charge the phone anytime, anywhere, and the charging speed is fast. But have you ever tried, the power bank will get hotter and hotter when charging, or even hotter to your hands. These are actually closely related to the shell of the power bank.

In fact, it is normal for the mobile power supply to generate heat during use, but if the mobile power supply overheats for a long time or fails to dissipate heat in time, it will affect its service life.

Why does the power bank become hot? In short, during the charging process of the power bank, part of the electricity will be consumed on the internal circuit board in the form of heat energy. If the heat energy cannot be dissipated in time, it will accumulate inside and cause the temperature of the case to rise. Then, the role played by the shell material of the power bank is more important.

The composition of the power bank is very simple. It is nothing more than three parts: the shell, the battery core and the circuit board. The three parts complement each other and are indispensable. Among them, the most frequently used by users is the case, because the case will form the first impression of the entire product, and the case can also protect the cells and circuit boards from damage during daily use.

At present, the shells used in power bank products on the market can be basically divided into two categories: metal and non-metal. Generally speaking, the non-metallic shell is made of ABS/PC plastic material, which has the characteristics of low ignition point and high temperature resistance. Even if the internal temperature of the mobile power supply is high for a long time, the shell is not easy to melt or burn, but the heat dissipation effect is not good. , Is very dangerous.

The metal shell is generally made of aluminum alloy, which is lighter. The manufactured power bank shell is more suitable for carrying and has better heat dissipation performance. The power bank made of aluminum alloy is very sturdy, and the metal shell is relatively more stable when subjected to external forces such as falling, rolling, and squeezing.

The power bank shell made of aluminum alloy can not only help the charger to dissipate heat, but also can be processed with paint and other processes to make the power bank look more beautiful. Zhigao Industrial is specialized in the production of various aluminum radiators such as electronic radiators, power amplifier radiators, audio radiators, etc. Zhigao Industrial can also process sandblasting/drawing/polishing/surface anodizing and hard oxidation. Efficiently dissipate heat for all kinds of electronic products, escort, and manufacture more beautiful power bank shells.
