How do cars cool down in summer

How to cool the car in summer? In hot summer, if the car is exposed to the sun for a long time, the paint will be damaged. And when you open the door, a heat wave hits, which will make people feel uncomfortable while driving. Let's analyze how to cool the car in summer.

How do cars cool down in summer? 1 causing problems:

1. Long-term exposure to the sun will lead to the aging of rubber products (such as door sealing strips and tires), and it may also lead to water leakage when it rains.

2, high temperature exposure will lead to glass breakage. After the glass is exposed to strong sunlight for a long time, the temperature will rise sharply and its physical properties will change. If you wash the glass with cold water, it is easy to break or damage its performance.

If the car is exposed to high temperature for a long time, the formaldehyde in the car will exceed the standard, and the formaldehyde index may even be three times higher than usual.

How to solve:

1, alcohol is cooled by adding water.

Alcohol and water absorb heat, so we can prepare a sprinkler, fill it with 3/4 water, pour in about 20 ml of alcohol (not too much), spray it quickly in the car after opening the car door, and then close the car door without opening the window. After a minute or two, the temperature inside the car will drop, and it will be much more comfortable to sit in the car.

Don't worry that spraying alcohol into the car will leave an odor, because the alcohol concentration is low, so the smell of alcohol will be eliminated in a few minutes. In addition, the ignition point of 100% pure alcohol is 75℃, and the lower the concentration, the higher the ignition point. When 75% medical alcohol is mixed with water at the ratio of 1: 10, it will not catch fire.

2, sunshade curtain

Sun protection for cars not only requires attention when parking, but also how to do sun protection for cars when driving, especially in the position near the window. Really getting sunburned is a kind of torture for drivers and passengers, and it will also damage the interior of the car.

In this way, we can put a parasol on the car, which can not only protect the sun and cool down, but also protect the privacy inside the car. The installation is simple for a few seconds, and the front windshield can be prepared, so that we can also use it to shade and cool down when parking.

3, car paint coating

It's too hot to leave the window open. If the journey is short, it can last for a while. But if the distance is long, it will be very uncomfortable in the car. Generally speaking, protecting the exterior of a car in summer means waxing. That is to say, paint the car with a layer of polymer structure paint containing ultraviolet reflector to reduce the damage of direct sunlight to the car.

In fact, there are many paint holes in the paint of cars. After waxing and painting, it is necessary not only to completely fill the paint holes invisible to the naked eye, but also to form a transparent "protective coating" on the paint surface of the car to achieve the purpose of shading. Protect paint and cool cars.

4. Automobile clothing

Although we can park our car in the shade, we don't always have the luck. Even if we park our car in the shade, we can't stop the wind and dust, so it's a good choice to prepare a sunshade coat for our car. It can block ultraviolet rays and prevent the surface of the car from being exposed to the sun.

The car clothes are very reflective, which can block 80% strong light and will not feel burning when entering the car. It can also effectively prevent the damage of rain, frost, wind and dust to the car. Whether it is summer or winter, car clothes are car clothes. Good helper.

In recent summers, it is not uncommon to see news that locking children in cars causes danger or even death. Even if such a tragedy didn't happen around us, we felt deeply about cars in summer in our life experience. The moment you open the door in summer, you seem to have entered a big oven, and its temperature must be much higher than the ambient temperature.

How to effectively cool the car?

Of course, there is another way, that is, we can sit in the car, then open the window of 1~2 on the car, then run for a while, and then by increasing the speed, we can quickly exhaust the hot air in the car after the airflow is smooth.

Then turn on the in-vehicle circulation. At this time, the temperature in our car will drop rapidly. After the early cooling, it will be more fuel-efficient to drive the car air conditioner.

So if we use this method, the temperature in the car will drop quickly, so that passengers and drivers on the car will feel particularly comfortable.

How to cool the car in summer 2 The first move: open and close the door.

This method is the simplest and most practical. First roll down the window of the cab door, and then repeatedly open and close the passenger cab door 10 times. Within 2 minutes, the temperature inside the car can drop by nearly 10℃.

The second measure: spray water to cool down.

Prepare a watering can, fill it with three-quarters of water, pour in about 20 ml of alcohol, spray it quickly after opening the door, and then close the door without opening the window. After a minute or two, the temperature inside the car will drop and it will be much more comfortable to enter the car.

The third measure: apply "sunscreen"

Even if you can't see any obvious changes in your car under the exposure, you should also coat your car with a layer of "sunscreen". Generally, in summer, the external protection of the vehicle is to glaze the vehicle. Glaze sealing is to coat the car with a layer of polymer structural paint care agent containing ultraviolet reflector to reduce the damage of direct sunlight to the car.

The fourth measure: holding a parasol.

When parking, the owner should not only consider the convenience of transportation, but also consider avoiding the problem of the vehicle being exposed to the hot sun as much as possible, and try to park the car in a cool and ventilated place. At the same time, when washing the car in summer, you can often clean the water tank to remove the debris attached to it, so that the engine can dissipate heat more easily. Experts suggest that it is a good choice to prepare an umbrella sunshade for your car.

How to cool the car in summer 3 Indoor parking lot/carport/under the tree

The first choice for car sun protection is naturally indoor parking lot. Basically, no matter what season or weather, the possibility of the car being affected by the outside world is extremely low. Moreover, indoor parking lots are generally clean and tidy, which can also reduce the frequency of car washing.

Sun-proof thermal insulation film

Of course, the above sunscreen methods are restricted by many external conditions. As a car owner, it is worthwhile to do some protection for your car, such as sticking a layer of sun protection and heat insulation film.

On the premise of ensuring that it is genuine, the thermal insulation film on the market is not bad. The general thermal insulation film can block more than 90% of ultraviolet rays, and the infrared blocking rate is also above 30%, and the effect is better.

Sunshade/car clothes

Shading is the most direct and effective heat insulation method when the sun is shining. This method can also be applied to cars.

Car sunshade can effectively block the sun and reduce the temperature inside the car, but it will be more troublesome to disassemble.

A sunshade/curtain

According to the position, the automobile sun visor can be divided into three types: front gear, side gear and rear gear, and the front gear is the most common one. Due to the large area and strong light transmittance of the front windshield of the car, the temperature in the car rises very quickly after direct sunlight; Sunshades are generally made of aluminum foil, which has strong reflection ability to sunlight and can avoid direct sunlight.
