How to solve the problem that the car is very hot in the sun?

How to solve the problem of hot car exposure? With the coming of summer, many people's cars are often exposed to the sun. The car is parked outdoors all the year round, and the exposure in summer will cause the car to be particularly hot, which many people can't stand. So how to solve the problem of hot car exposure?

How to solve 1 1, open the external circulation ventilation.

In fact, it is normal that the temperature is high and the weather is sultry in summer. Most riders will choose to close the window and turn on the air conditioner. But it is extremely wrong to do it after exposure.

Don't turn on the air conditioner before entering the car. First, open the external circulation, turn the air volume to the maximum, and open all the windows and skylights at the same time to achieve the purpose of rapid cooling. After this situation lasts for a few minutes, the temperature in the car will soon drop to a level that the human body can bear, and the driver can consider entering the car for long-distance driving.

2, stick explosion-proof heat insulation film

Putting an explosion-proof insulation film on your car is equivalent to putting a layer of sunscreen on it. This is the simplest and most direct way to prevent the sun exposure in your car at present, because the explosion-proof film can insulate heat, isolate ultraviolet rays, prevent explosion, and emit some heat, effectively reducing the heat from entering the car. However, the explosion-proof membranes on the market are uneven, and the car mainly pays special attention.

Step 3 use a parasol

Exposure to the sun for a long time will accelerate the aging of paint and instrument panel, and the high temperature in the car will increase the air conditioning load and fuel consumption. The most common aluminum foil sunshade on the market, which covers the front window after parking, can effectively protect the interior of the car and reduce the temperature.

There are two kinds of aluminum foil shading: bubbles and stripes, which can reflect ultraviolet rays. After unfolding, it can be fixed on the front window or rear window with suction cups. Horizontal stripes are better, aluminum foil is better outward, reflecting sunlight is better, and it can be folded when not in use. One end of the sunshade is fixed above the window, and the other end can be pulled down from the lower edge of the window, which can be quickly rolled up when not in use. Of course, the window insulation curtain is also very effective and cheap.

4, let the car and outdoor "contact"

Parking at high temperature, if the car is around, you can leave a gap of 1~2 cm for each of the four windows after parking to facilitate air circulation. When driving again, the car will not be as hot as when it is usually closed.

This will help the air convection inside and outside the car, exhaust hot air and harmful gases, and the temperature inside the car is not so high. Of course, if you want to guard against theft, you must be cautious, not only to ensure cooling, but also to ensure safety.

How to solve the problem that the car is very hot in the sun 2 1 Clean the water tank.

Many car owners are not particularly concerned about the cleaning of water tanks. In fact, cleaning the water tank regularly can also play a role in cooling down, because some impurities are often attached to the water tank, which will accumulate over time and reduce the heat dissipation efficiency. So don't forget to clean the water tank when washing the car.

2. Sealing glaze and waxing

Exposure to the hot sun does great harm to car paint. Long-term exposure will accelerate the aging and fading of car paint, make the car lose its original beautiful luster and affect the life of car paint. It is best to seal and wax the car paint, effectively isolate and protect the car paint and protect the car.

3. Leave a gap to dissipate heat

The reason why the temperature inside the car is high after exposure is that the car is in a sealed state, and the hot air inside can't touch the outside air, so it will accumulate in the car, so many smart car owners will consider leaving a gap of 1~2 cm for each of the four windows to ensure air circulation.

The temperature inside the car will not be as hot as it is in the usual sealed state, and the air conditioner on the car can achieve a good cooling effect after a while. (However, using this method, drivers must be careful to ensure that the parking area is absolutely safe before using it. ).

Use a sun visor

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.

In addition, it is also a good choice to prepare an umbrella sunshade for your car. Sun visor is suitable for outdoor short-time parking. After parking, you need to put the sun visor on the inside of the front and rear windshields.

How to solve the problems caused by hot car exposure;

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, open and close the door

The hot air in the car has been lingering, mainly because the hot air in the car has not circulated. We can lower the temperature by opening and closing 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 door 10 times at the position of the auxiliary cab. Within two minutes, the temperature inside the car will drop by nearly 10 degrees Celsius.

Its principle is similar to air conditioning. Because the hot air floats on the cold air, opening and closing the door introduces a lot of cold air lower than the hot air in the car, and this is repeated ten times to strengthen the air circulation inside and outside the car, so that the hot air can be discharged quickly and the cooling speed is very fast.

2. Mix alcohol and water to cool down.

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.

3, 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 also be prepared, so that we can also use it to shade and cool down when parking.

4, 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.

5, car clothes

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 a good helper for cars.
