Is the laptop power adapter hot?

In fact, when you use a notebook, if the data is relatively large, then the power consumption of the notebook is correspondingly large, and at the same time, the laptop battery is also charging, especially in the summer, you will find that the shell is hot when you touch the laptop power adapter, in fact, there are power supplies such as the router, and the phone charger will heat up the shell during use. Because it needs to emit the temperature of the components inside, so as to ensure the safe operation and work of the electronic components inside. As long as the housing temperature is 25 degrees above the ambient temperature, the laptop power adapter housing is normal.

What if the power adapter is hot? Does the power adapter need heat dissipation?

When we place the power adapter, we can not put it in the sun, if the sun shines under the shell itself will absorb the heat radiation of the sun, do not put it in a sealed small space such as in a sealed box, try to put it in a ventilated and cool place, and it can not cover debris, nor can several working power adapters be stacked to At the same time, if there is a very thick ash on the shell, it is not convenient to dissipate heat, so it should also pay attention to cleaning. In the case of conditions, especially in the case of harsh environment, we can consider using a chassis cooling fan to cool the power adapter.

If it is not the original power adapter but a replacement power adapter, and placed in a cool and ventilated situation, it is not covered with debris, and the shell is too hot, first measure whether the shell temperature is more than 25 degrees higher than the ambient temperature. Then check whether the rated power of the original power adapter is the same or greater than the original power adapter, the power is less than the previous rated power, and the housing temperature will certainly be very hot at full load or even overload operation, which will shrink its service life.
