When charging the mobile phone, we often encounter the problem of the phone burning. In fact, the phone burning is related to the current intensity and environment of the phone charging. The higher the current, the faster the phone will charge. This often leads to the serious phone burning.Besides the current, the size of the fast wall charger is also a problem. Now, for the convenience of going out, people tend to use smaller chargers to carry around, As the size of the charger gets smaller, the heat dissipation will become worse. Let us explain why the mobile phone is hot, and what is the solution to the problem?
The components of PD charger that generate a lot of heat are: high-voltage capacitor, switch tube and high-frequency transformer. The temperature of these three components is quite high. It is not difficult to reduce the temperature of these three components. Generally speaking, when the output current is unchanged, the power of high-frequency transformer is relatively large, and the temperature of high-power high-frequency transformer is much smaller. In short, it is necessary to give it extra power, just like a cart pulling small things. Of course, it is easier for the switch tube to dissipate heat, as long as it is equipped with enough heat sinks. However, due to volume limitations, it is impossible to reduce heat generation. Therefore, it is inevitable that the usb wall charger will heat up.
Of course, the above only refers to the heating of the high quality fast charger . If it is a low quality charger, it is another matter. The stability of the output voltage of the charger itself is not stable, which will cause slow charging, serious heating of the charger and other problems.
