How dangerous is a closed car?

As the weather is getting hotter, accidents in the car often cause accidents due to high temperature. In order to measure how high the temperature in the car is exposed, the staff did an experiment of "high temperature in the car" in the summer. Under the conditions of direct temperature and sunlight in summer, the temperature meter was used to observe the temperature and the temperature in the car. Comparison observation experiment.

The results show that the vehicle can reach the temperature difference between the inside and outside of the car within 40 minutes in the open -air sun's direct environment in 40 minutes. As the temperature increases, when the temperature is 33.0 ° C, the maximum temperature difference reaches 45.5 ° C, and the temperature in the car reaches 78.5 ° C!

Even the cooler places can rise to 47 ° C within an hour, even if the window seam is opened, it will not have any effect.

It is worth noting that children cannot regulate their body temperature like adults, especially children under the age of 3 are locked in a closed carriage for 15 minutes. , Heat stroke, shock, and even suffocating.

For children under 15 years old, in addition to a car accident, heat stroke in the car has become the second cause of death in the vehicle -related death.

A few days ago, in Wuxi, Jiangsu, a young child was locked in a car. He was afraid of crying. Firefighters came to rescue, but parents wanted to wait for the unlocking master to open the door instead of the source of the window.

The smell is accelerated at high temperature, and the odor is more likely to produce.

The formaldehyde boiling point is -19.5 ° C, which is easy to volatilize and has a irritating effect on human eyes and nose. It is the main source of its pieces.

Studies have shown that the quality concentration of formaldehyde at high temperature can reach more than 10 times at room temperature.

In addition to the "five benzenedehyde", there are a variety of organic compounds in the car, including direct chain alkanes, branched alkanes, and parts of phenyl, cyclumanes, esters, and aldehydes, which are stimulating. The human body is harmful.

In addition, items that are usually randomly placed in the car are likely to cause explosion in high temperature days, including lighter, old flower mirrors, perfumes, carbonated drinks, cooling spray, insect -proof spray, sunscreen spray, and so on.

Studies have shown that the sunscreen spray burst into fire in 1 second.

How to cool down in the car?

On the hot summer, the car was exposed to the sun; the door opened the door, and a heat wave struck; when it was in the car, it was all sinful. So, what methods can quickly cool the vehicle?

01 Natural environment cooling

This is the simplest and most direct solution. If there is an underground garage, it is the best. If not, the vehicle is parked as much as possible under the big tree or a cool place.

02 Switching car door cools down

Before getting on the car, when you ensure safety, the door is repeatedly switched at least 5 times. Using the principle of the "pulling box" principle to quickly disperse the harmful gases emitted by the exposure in the car, while cooling the seat.

03 clever driving window cooling

Regarding the correct windows ventilation method, the following two types are recommended to quickly achieve the effect of cooling down.

Method 1: Two windows that turn on the diagonal corner are equivalent to "piercing the wind", so that the air of the convection flow forms a soft "small whirlwind". The cooling effect is good and the noise is very small.

Method 2: Close the car window of the driver's seat and open the remaining three windows. In this way, the ventilation can not only gather a large amount of air to the rear row to form a high -pressure area, accelerate the heat exhaust, and the wind is very soft.

04 Air conditioning cooling

After the vehicle starts, don't turn on the air conditioner immediately. At this time, the air conditioner not only increases fuel consumption, but also causes the engine to damage to varying degrees. It is recommended that you open the window for about three minutes and then turn on the air conditioner to enjoy the air conditioner more economical and quickly.

There are also several tips for the use of air conditioners in the car. First of all, turn on the air -conditioning circulation, the air volume is to the maximum, and the windows are opened at the same time. This is to allow the air in the inside and outside of the car to flow in the inside and outside of the car, and discharge high -temperature gas as soon as possible. Then close the window, switch the air conditioner to the inner cycle, and adjust it to the temperature and air volume that you feel comfortable. The air outlet is up, and the cold air will automatically sink to improve the refrigeration efficiency.

05 Sun Sun Calling Cooling

After the vehicle is parked, the installation of sunny curtains can effectively resist most of the direct sunlight and reduce the temperature in the seat and the internal vehicle. Car -bearing parasol can also have the same cooling effect.
