Summer car quickly cools

In summer, when the car is exposed to sunlight for a short time, the temperature inside the car will soar. Once you open the door, the heat waves will blow and people will not be able to seat you. So how can we quickly reduce the temperature inside the car? Today Xiaobian summarizes several effective methods for everyone.

1. Switching the door This method is the most popular method on the Internet, and it is also the most simple and practical. First, roll down the window on the door of the cab and then repeatedly open and close the door of the cab for 10 times. Because the hot air floats on the cold air, the opening and closing door brings in a large amount 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, so that the hot air is quickly discharged and the cooling is quick. It is said that within 2 minutes, the temperature in the vehicle can drop by nearly 10°C. But taking the heat to open and close the door is also a coolie!

2. Evaporative heat absorption method We know that the liquid will absorb the surrounding heat when it evaporates, so we can use this principle to reduce the temperature. Materials We can use water, alcohol, or a mixture of water and alcohol. Using a watering can, we spray a few times in the car and close the door. After about two minutes, the interior temperature drops. Note that the ignition point of 100% pure alcohol is 75°C. The lower the concentration, the higher the ignition point. The concentration of 75% of medicinal alcohol, so we do not have to worry about the fire.

3. Car temperature-reducing agent The car cooling agent is mainly made of dry ice, using dry ice above 50°C for explosive cooling, plus some natural flavors and softeners. It is more powerful and can cool down quickly by 20°C to 40°C. When using, open the external circulation of the car air conditioner first, open all the windows and skylights at the same time, and then spray the cooling agent evenly into the space inside the car to cool down in 30 seconds. But pay attention to the cooling agent is often placed in the car is not safe, direct exposure to more than 50 °C easy to explode.

4. The solar thermal desuperheater is a new type of cooling device that uses sunlight and ambient light to directly convert electricity into electricity, and drives motors and fans to exert heat to remove heat. The main advantage is that the temperature can be continuously reduced, unlike the above method is to cool the temperature in a short time, it can keep the temperature inside the car will not be too high. When the car temperature reaches 28°C or above, the microcomputer temperature controller can automatically activate the desuperheater and begin to cool the car. When the car starts to start the air conditioner, it does not need any switch, and the desuperheater is temporarily turned off to prevent the loss of the air-conditioning air-conditioning. However, the only drawback is that the price is slightly expensive, and the market is chaotic. There are many counterfeit counterfeits.

5. Automobile coating film is generally for the protection of the car, of course, to a certain extent, to achieve the purpose of sun protection. The paint coating coats a special chemical on the surface of the paint, and uses the chemical change of the paint on the surface of the paint to form a thin, hard and transparent protective film so as to protect the paint during a certain period of time. Affected by external contamination, impurities, etc., it can not only achieve the purpose of painting without oxidation, easy to clean, and maintaining beautiful effects, but also can block the exposure of a certain UV to the car, thereby reducing the temperature inside the car.
