Indeed, the majority of residents frequently hear others talk about auto radiator in their daily lives. What's more, some people may even consider auto radiator as a reassurance to the car. It is widely known that auto radiator is virtually the vehicle's water tank and can be used for the purpose of vehicle heat radiation. But, do you know the reason why auto radiator is considered by many as a reassurance to the car? Have you ever got to learn something about auto radiator previously? Here we shall answer these questions and probe into the main functions and working principle of auto radiator from the following aspects.

Firstly, we must get to know the basic composition of auto radiator. Generally speaking, auto radiator consists of water pipe, radiator, steam valve, air hole, cooling water and water jacket. In most cases, water pipe and radiator are made of aluminum. Of course, other kinds of materials may also be used to produce the water pipe and radiator of auto radiator. Besides, water pipe is usually oblate while radiator is corrugated. Of course, the whole auto radiator is one of the most important parts of the whole cooling system.

Secondly, we need to get to know the main functions of auto radiator. For the purpose of understanding why auto radiator is said to be a reassurance to the car, we must, first of all, get to understand the main functions of auto radiator. Basically, one of the main functions of auto radiator is heat radiation. Cooling water in the water jacket absorbs heat produced by engine and flows to radiator. Then, heat will be discharged through auto radiator. In this way, auto radiator not only helps speed up heat radiation but also helps prevent the operating temperature of the vehicle's engine from being too high. It is especially in summer when the car has to be exposed to heat. In this sense, it is not hard to understand why auto radiator works as a reassurance to the car.

Lastly, we should get to understand the working principle of auto radiator. Just as mentioned above, there is some cooling water in the water jacket. When water temperature is too high, cooling water inside the auto radiator will swell and produce substantial steam pressure which will open the steam valve. In this way, heat will be discharged from the steam valve efficiently. On the other hand, if water temperature is too low, pressure inside the auto radiator will decrease, which will open the air hole. Then, external air will be able to come in, which helps ensure the stability of pressure inside the auto radiator.

In short, from what be discussed above, as long as we get to understand the main functions and working principle of auto radiator, we can easily understand why auto radiator is considered as a reassurance to the car.
