As soon as the rainy season was over, the Japanese archipelago was wrapped in intense heat.Do you know how much the inside of the summer car will be at a hot day exceeding 35 ° C?If you leave the curma while the strong sunlight shines, it is not unusual for the room temperature to exceed 50 ° C in 30 minutes.As expected, the rise from there seems to be gentle, but it can exceed 60 ° C.
The air inside the car is warmed by the heat of dashboards and seats, so the dashboard, which is the heat -generated body, can reach a high temperature of nearly 80 ° C.This varies depending on the body color and the color of the dashboard, but in the sunshine in the intense heat, there is only a difference of about 5 ° C.It gets so hot.
The first thing that should not be left in such an environment is electronic devices, that is, smartphones and notebook PCs.There are operating warranty temperature (there is also the expression of operating temperature, operating environment temperature, and operating surrounding temperature).This is a condition that guarantees normal movements and original performance by using within the temperature.Sentence / Hideyuki Takane Photo / Adobe Stock, Best Car Editorial Department (Tobira Photo = Adobe Stock@Yamasan 2)

■ Pay attention to the operating temperature and storage temperature of smartphones and laptops
For example, the operating temperature of the iPhone is 0 ° C to 35 ° C, and a general smartphone can be considered at almost the same level.This is the outside temperature, and the temperature inside the smartphone during the operation is even higher.Therefore, when heated from the outside, it does not work normally, not only cooling inside the smartphone, but also the heat is transmitted inside.
Furthermore, there are many cases where the environmental conditions are determined in the non -operating warranty temperature (also called the storage temperature), that is, the environmental conditions.Not all PCs have published such conditions, but Japanese PC manufacturers have relatively strict inspections and have many items.According to those data, the warranty temperature in non -operating is about 60 ° C.In other words, the inside of the midsummer car is a last minute environment, and it can be called a dangerous thread.
By the way, when we talk about the internal temperature during the operation, it is said that Intel's CPU will enter safe mode at 105 ° C.In other words, it is always cooled by heat sinks and fans so that it does not become so hot, but if the surrounding temperature is high, the heat replacement will not work well.Still, it's still good if it just becomes temporarily unusable.
Power supply and batteries are more damaging on PCs than that.Since the lithium -ion battery uses an organic solvent for the electrolytic solution, when the temperature rises, the risk of expanding and ignition of the battery case increases.Electric double -layer condensers are used for the power supply, and as the temperature rises, the life is shorter.It should be remembered that if the storage temperature exceeds the storage temperature, it will not break quickly, but the life will definitely be shorter.
■ Is it useless in the car even in a short time?
It's often the case to leave your luggage in the car when you leave the car for a while.
The sensation differs depending on the individual, but if you know the above -mentioned temperature rise, you can see that the level is out of the level.If it is about 10 minutes, it will be safe depending on the situation, but if you want to make your smartphone last longer, do not put it on the dashboard.
In addition, electronic devices are not the only things that should not be left in the car.Sweets (gum, candy, etc.), spray cans, carbonated drinks, 100 yen lighter ...All of them are too dangerous to put them on the dashboard.In the JAF user test, a 100 -yen lighter rising internal pressure, causing cracks to the case, and the gas leaked.If gas is filled in the car, it can be a fire, which is very dangerous.
There is a risk that organic solvents will be scattered in the room for ballpoint pens and magic, so it is better to stop placing them on the dashboard.If you feel sick before you change the air inside the car, it's dangerous to drive.
