The high outdoor temperature is a scorching test for vehicles parked outdoors. Since the metal material of the car shell itself is very heat-absorbing, it will continuously dissipate heat into the car. In addition, it is difficult to circulate the heat in the closed space inside the car. After exposure to the sun, the temperature inside the car can easily reach dozens of degrees. In hot weather, the moment you open the door and get in the car, a heat wave hits your face! The editor will introduce to you 5 ways to cool down.

1. Open the car window. If you want to cool your car, you must first open the windows to let the hot air flow out of the car. This method is simple and effective, but you still need to wait a few minutes after opening the window. At this time, should you sit in the car or wait outside the car? If there is a cool shelter nearby, you can take shelter. If not, you have to endure the high temperature.

2. Turn on the air conditioner immediately after getting in the car. While this method can quickly cool down your car’s interior, I wouldn’t recommend it to you. There is a method for the correct use of car air conditioners in summer: first, open the windows and turn on the air conditioner. Wait about 5 minutes, close the window, and turn on the AC switch of the air conditioner. We need to remind everyone that internal circulation and external circulation should be used alternately to keep the air in the car fresh. In summer, it is easy to cause heatstroke or hypoxia in the car, so we need to open the windows for ventilation.

3. How to open and close the door. This method is very popular on the Internet. The passenger side window glass is fully opened and the main driver’s side door is quickly opened and closed. This uses the principle of bellows to quickly discharge the hot air in the car. The editor has tested this method and it works very well.

4. Solar window exhaust fan. I saw someone using this tool the other day. In fact, it is a solar panel with a fan. Its principle is similar to that of an exhaust fan, but the problem is that it must have a lithium battery inside, otherwise it will be solar power. But is it really good to put lithium batteries in the car in the summer?

5. Car air coolant. This coolant is actually dry ice. After it is sprayed into the car, it can quickly absorb the hot air in the car, thus achieving the effect of cooling the air in the car. This car air coolant is harmless to humans and has no odor. It’s not expensive at 20 to 30 yuan, and one bottle can last a long time. Of course, if you want to save money, you can also buy a spray can with denatured alcohol in it, but the cooling effect is far less than that of dry ice.
