When you unplug the power adapter after charging the notebook, you will find that the power adapter is hot and the temperature is too high. Is it normal for the notebook power adapter to be hot during charging? How to solve this problem? This article will solve our doubts.
It is a normal phenomenon that the notebook power adapter is hot when in use. It has been running all the time. To convert the output power, it will lose kinetic energy and some of it will become heat. At the same time, it also needs to see whether the battery is installed or whether the battery is normal, etc. Notebook power adapter is actually a high-precision and efficient switching regulated power supply. Its function is to convert 220V AC mains power into low-voltage DC power to provide stable power for the normal operation of notebook computers. It is even known as the “power source” of notebook computers.
The conversion efficiency of the power adapter to the power supply can only reach about 75-85 at this stage. During voltage conversion, some kinetic energy is lost, and most of it is emitted in the form of heat except a small part in the form of wave. The greater the power of the power adapter, the more kinetic energy will be lost, and the greater the heating capacity of the power supply.
At this stage, the power adapters on the market are sealed and encapsulated with fireproof and high-temperature resistant plastic, and the heat generated inside is mainly transmitted and emitted through the plastic shell. Therefore, the surface temperature of the power adapter is still quite high, and the maximum temperature will even reach about 70 degrees.
As long as the temperature of the power adapter is within the design area, in other words, the temperature of the power adapter is within the normal area, there is usually no danger!
In summer, you should pay more attention to the heat dissipation of the laptop itself! The most important thing is to ensure the room temperature. If the room temperature is too high, no matter how heat dissipation is useless! It’s best to turn on the air conditioner when using the notebook! At the same time, the bottom of the notebook should be raised as much as possible, and the bottom of the notebook can be padded up with special heat dissipation brackets or articles of equal thickness and small size! Try not to use the keyboard protective film, because the keyboard is also the key component of notebook heat dissipation! Other heat dissipation parts (the heat dissipation parts of notebooks of each enterprise brand may be different) should not be covered by objects!
In addition, it is also necessary to regularly clean the dust at the outlet of the cooling fan! In the hot summer, the notebook needs your double care!
