In our daily lives, we often use a variety of electronic devices, and the chargers of these devices are also indispensable. However, sometimes during the charging process, we will find that the charger is hot, and even sometimes it is hot to the hand. Why is that?This article will explain this phenomenon in detail.
OneThe heat generated by the energy conversion
During the charging process, the charger actually converts electrical energy into chemical energy and stores it in the battery. This conversion process is not 100% efficient, and a part of the electrical energy will be converted into thermal energy. Therefore, it is normal for the charger to heat up while charging, and this heating is usually mild and does not pose a safety concern.
IICharger design issues
Insufficient heat dissipation design: Due to design problems, some chargers have poor heat dissipation performance, resulting in heat dissipation that cannot be effectively dissipated, resulting in charger heating.
Material selection: The material of the charger housing will also affect the heat dissipation effect. For example, a heat sink made of plastic is worse than a metal one.
IIIThe charger is overloaded
When the charger outputs more current than its rated value, an overload phenomenon occurs. An overload causes the temperature of the components inside the charger to rise, which can cause the entire charger to heat up. Prolonged overload will not only affect the life of the charger, but may also cause safety hazards.
FourthExternal environmental factors
Ambient temperature: When charging in a high-temperature environment, the heat dissipation effect of the charger will be affected, resulting in heat accumulation, which will cause the charger to heat up.
Air circulation: If the air circulation around the charger is not smooth, it will also affect the heat dissipation effect and cause the charger to heat up.
In general, it is normal for the charger to heat up while charging, but if you find that the charger is abnormally hot, such as the temperature is too high or accompanied by peculiar smell, you should stop using it immediately and check the cause. The safe use of electronic devices not only protects our property, but also is responsible for the environment. Hopefully, this article will help you better understand why chargers heat up and use electronic devices more safely in your daily life.
