When the car was exposed to the sun for several hours, the door opened and the heat wave rushed forward. Many people would immediately turn on the air conditioner. They did not know that this would waste a lot of energy. Many office workers, they usually stay indoors, the temperature is only about 20 °C, and get into the car after work, but suffered a high temperature sauna near 50 °C, huge gaps make it difficult to adapt, but direct air conditioning cooling and too much Yes, there are no other rapid cooling methods?

The first move: switch the door
This method is the most simple and practical. First, the window of the cab side door is shaken down, and then the door of the front passenger compartment is repeatedly opened and closed 10 times. Within 2 minutes, the temperature inside the car can drop by nearly 10°C.
Principle: The principle is similar to that of air conditioners. Because hot air floats on cold air, the door opens and closes a large number of cold air that is lower than the hot air in the vehicle. Repeatedly ten times, the air circulation inside and outside the vehicle is strengthened, and the hot air is quickly discharged. So cool down quickly.
Reminder: When you open the main door, you only need to shake down the driver's window. This effect is better than the full-open door, which can also prevent the door hinge from rusting.
The second measure: spray water cooling
Prepare a watering can, put in three quarters of water, pour about 20 ml of alcohol, open the door, spray it a few times, then close the door. Do not drive the window. After a minute or two, the temperature inside the car will come down and it will be much more comfortable to enter the car.
Principle: Alcohol and water are endothermic. The owner may wish to prepare a small spray bottle or an empty hair spray bottle in the car, and mix and bottling according to the ratio of alcohol and water 1:10.
Warm reminder: Alcohol odor will be eliminated in minutes. In addition, the ignition point of 100% pure alcohol is 75°C. The lower the concentration, the higher the ignition point. The medicinal alcohol with a concentration of 75% will not ignite under normal circumstances after diluting water in a ratio of 1:10.
The third measure: painted "sunscreen"
Even if you do not see the obvious changes in the car under the exposure, but also to the car painted a layer of "sunscreen." Generally, the protection of the exterior of the vehicle in summer is to seal the car. Sealing glaze is to apply a layer of polymer paint finish agent containing UV reflectors to reduce the damage to the car caused by direct sunlight.
Principle: With the car's glossy finish, there are a lot of paint holes in the car. The car seals the glaze, not only to completely fill the paint holes that are invisible to the naked eye, but also to form a layer on the surface of the car's paint surface. Transparent "protective clothing" to achieve the purpose of sun protection.
Reminder: This kind of sunscreen has a high cost, which generally requires about 300 yuan at a time. If you do not wash your car, the sunscreen effect can be maintained for three to four weeks.
The fourth measure: support umbrellas
When parking the car, the car owner must consider not only the convenience of transportation, but also the issue of preventing the vehicle from being exposed to the hot sun as much as possible. Try to park the car in a cool, ventilated place. At the same time, when washing cars in summer, you can often clean the water tank and remove the debris attached to it, so that the engine can easily dissipate heat. Experts suggest that preparing a protective sun visor for cars is a good choice.
Principle: The visor is usually made of tin foil and foldable. Its material has a lot of good reflection, can block 80% of the sun's glare, use it will not make you have a burning feeling when you enter the car. Just open the sun visor, suck the sucker on the glass, the price is usually around 20 yuan.
Reminder: The sun visor is suitable for short-term outdoor parking. After parking, the sun visor needs to be placed inside the front and rear windshields.
In addition, there is a zero-cost cooling method in addition to the methods described earlier. After the car owner stops, if you do not want to burn the car when you drive again, you can consider to leave a gap of 1 to 2 cm for each of the four windows to facilitate air circulation. When the car is turned on again, the car will not be closed as usual. So hot.
