The brain is suddenly jerking off, this wonderful cycle

, assuming that the device 1 is not working before power on, the heatsink is not working, the Power module (Low efficiency boost module) is not hot, its temperature is equal to room temperature, the heatsink threshold operating temperature is slightly higher than the room temperature, then the heatsink does not work. When device 1 is enabled (assuming that the device 1 is large enough to heat the power supply), the heatsink starts to work after the temperature rise is detected (assuming that the power of the heatsink is also large enough to cause the power supply to heat up, ... ^_^ is wonderful! ) to heat the power supply. If you disconnect the device 1 at this time, the power of the heatsink still make the power supply has a certain heat so that the radiator must also work under a certain intensity of power conditions, so it is not a vicious circle? It's like fission. Although these are just assumptions, there will be no such slag products are really in use, but just suddenly think of such a situation, feel very scary 、、、
