Charger hot cause:
Charger heat is normal, which is related to the strength of the current output of the charger and the ambient temperature, with the popularity of smart phones, now the charger requirements are more and more high, the charger of 500ma in the era of the functional machine can not satisfy the user's demand for charging speed.
Charger in charging, you should use the original charger, which can ensure the output current is stable, there is a role in protecting the battery, can better reduce the heat of the charger. Generally speaking, chargers that are not original will easily get hot, and even have the possibility of burning out.
Charger hot mainly and charger output current strength; now we are generally using 2A fast charging, charging temperature is generally not working and the difference is about 5 °, then if you use a constant voltage flash charger, then the degree of heat is certainly more serious than the 2A fast charging.
The size of the appliance is also a problem, in order to carry convenient, chargers will pursue the product size smaller, then the heat dissipation performance will become worse, the higher the requirements of the electronic components, the big company solution is to increase the heat dissipation patches on the heat source.
Charger is a device for charging other electrical appliances. The use of power electronics semiconductor devices, the voltage and frequency of fixed alternating current into direct current, generally composed of flexible circuit boards, electronic components, etc., according to the design of the circuit operating frequency can be divided into industrial frequency machine and high frequency machine, in various territories are widely used.
Charger heating components are: high-voltage capacitors, switching tubes, high-frequency transformer, the temperature of these three components is quite high, to reduce the temperature of these three components is not difficult, in general, in the case of the output current is unchanged, high-frequency transformer power to be relatively large, with high-power high-frequency transformer temperature to be much smaller.
The harm of not pulling the charger
As the charger consists of electronic components, long-term charger plugged into the socket, it is easy to cause heat, resulting in pieces of aging, and even short circuit, greatly shortening the service life of the charger!
Charger (especially low-quality chargers) has been plugged into the socket for a long time, resulting in serious heating of the charger itself, coupled with the living environment, closed, hot summer and other reasons, easy to cause spontaneous combustion of the charger since the explosion!
