What should I do if the 24V power adapter is very hot? Does the power adapter need heat dissipation? In fact, any power adapter will emit heat during use. This heat is dissipated through the shell of the power adapter. As long as the original power adapter is basically nothing The problem, in the safety regulations, is generally stipulated that the ambient temperature is plus 25°. Because the manufacturer will consider this power consumption and temperature rise when designing the product to match the power adapter.

In fact, when you are using a notebook, if the data running on the notebook is relatively large, the power consumption of the notebook is correspondingly large, and at the same time, the notebook battery is also being charged, especially in summer, when you touch the notebook 24V power adapter, you will find that the shell is relatively large. Hot, in fact, such as the power supply of the router, the charger of the mobile phone will heat up during use. Because it needs to dissipate the temperature of the components inside, so as to ensure the safe operation and work of the electronic components inside. As long as It is normal for the case of the laptop power adapter to be hot when the case temperature is at the ambient temperature plus 25 degrees.
When we place the 24V power adapter, it cannot be placed under sunlight. If it is exposed to sunlight, the shell itself will absorb the heat radiation from the sun. Do not place it in a small sealed space, such as in a sealed box And so on, try to put it in a ventilated and cool place, and it should not be covered with sundries, and it is not allowed to stack several working 24V power adapters together. , so pay attention to cleaning. Under conditions, especially in harsh environments, we can consider using a chassis cooling fan to dissipate heat from the power adapter.
If it is not the original 24V power adapter but a replacement power adapter, and it is placed in a cool and ventilated condition, it is not covered with debris, and the case is too hot, first measure whether the case temperature is 25 degrees higher than the ambient temperature. Check whether the rated power of the original power adapter is the same as or greater than that of the original power adapter. The power is less than the previous rated power. The case temperature will definitely be very hot under full load or even overload operation, which will shorten its service life.
