Whether it is a power adapter or a charger, the temperature rise of the power supply itself is a very important parameter indicator. Next, Senshuqiang Electronics will talk to you about the temperature of the power supply.
First: the reason why the power adapter heats up:
When the power adapter performs voltage conversion, part of the energy is lost, and most of it is dissipated in the form of heat except for a small part of the loss in the form of waves. The greater the power of the power adapter, the more energy is lost, and the greater the heat generated by the power supply.
Second: When the power adapter is in normal use, what is the normal surface temperature?
In the development stage of the power adapter, there will be various parameter performance tests and evaluations. One of them is temperature. Under normal circumstances, the surface temperature rise of the power adapter will be controlled within 30-35 ℃. As we all know, the power adapter is used indoors, so the indoor temperature will not exceed 40 ℃ under normal circumstances, and it is usually around 25 ℃. Then even when the maximum temperature is 40°C, the housing temperature of the power adapter is within 75°C. The temperature resistance of the shell is about 100℃, while the temperature resistance of the nameplate sticker is about 80℃. So 75°C is almost the limit. In fact, as long as the temperature of the power adapter is within the design range, that is to say, the temperature is within the normal range, it is generally not dangerous!
Third: the solution to the heat of the power adapter
It is inevitable that the power adapter will heat up, but it can be accelerated to prevent its temperature from rising continuously.
1. When using in a high temperature environment, the power adapter should be placed in a place that is not exposed to direct sunlight and is well ventilated;
2. Create a good heat dissipation environment, and place the power adapter in a location that is not exposed to sunlight and ventilated.
