When many people buy a notebook or notebook power supply, they may encounter a situation in which the power supply is hot. Is there a quality problem with the power supply? Is this normal? How to solve this problem? Yuda mobile accessories distributor for everyone solve problems.
First, why is the 5V1A power adapter hot?
What temperature range is the normal range? The conversion efficiency of the power adapter can only reach about 75%-85%. It is still difficult to find a better way to convert. When the power adapter is performing voltage conversion, part of the energy is lost. Except for a small part of the loss in the form of waves, most of it is emitted by heat. The greater the power of the power adapter, the more energy is lost, and the heat generated by the power supply is greater. This is why the desktop power supply needs a fan to dissipate heat.
Therefore, when designing and manufacturing, we must choose high temperature resistant components. Of course, the temperature of the power adapter must be controlled within the allowable range of the application environment.
Second, the notebook power adapter is hot when used:
It is normal for the notebook power adapter to heat up during use. It has been working. To convert the output power, it will consume energy, and some will become heat. It also depends on whether the battery is installed or the battery is normal. The notebook power adapter is actually a high-efficiency switch-type regulated power supply. Its function is to convert 220v/110v AC power into low-voltage DC power to provide stable power for the normal operation of the notebook computer.
As long as the temperature of the power adapter is within the design range, that is, the power adapter temperature is within the normal range, it is generally not dangerous!
Third, how to solve the problem of overheating of the power supply?
We should first buy a genuine power supply. First, look at the label. The information given on the label is generally very complete. There will be product certification information and manufacturer information. Generally, the power adapter is more reliable after product certification. The second point is the brand, the brand is also very important, although the choice of the brand’s power adapter, his power adapter price may be higher.
Fourth, how to solve the problem of overheating of the power supply?
1. Create a good heat dissipation environment and place the power adapter in a ventilated position. Do not use it for too long at high temperatures. If it must be used for a long time, be sure to pay attention to heat dissipation.
2. The power adapter heat is generally caused by battery charging and computer consumption. We can set it up in a notebook with battery management software.
3. Always wipe the adapter with a dry rag or paper towel to prevent dust from entering the adapter and reduce the heat dissipation of the adapter.
