How a car radiator works

I. Introduction
The automobile radiator is an important part of the automobile engine cooling system, and its main role is to dissipate the heat generated by the engine through the radiator, so as to ensure the normal operation of the engine. In this paper, the structure of the radiator and the maintenance of the working outlet will be introduced in detail.
Second, the structure of heat dissipation II
1. Radiator shell: TS is made of aluminum alloy material, which has good thermal conductivity and portability.
2. Water tank: The upper water tank is connected to the inlet water pipe and outlet water pipe, and the lower water tank is connected to the coolant pipe.
3. Fin: installed inside the radiator to increase surface area and enhance heat dissipation effect.
4. Water pump: It is responsible for extracting the coolant from the lower water tank and sending it to the engine through the water inlet pipe.
5. Fan: Usually installed behind the radiator, the fan is driven by wind during driving to enhance the cooling effect of air on the radiator.
Third, the working principle of the radiator
1. Coolant circulation system
The coolant enters the engine from the lower water tank, flows through the circulation system, absorbs the heat generated by the engine and returns to the radiator. During the circulation process, the coolant flows continuously through the drive of the pump, thus forming a closed circulation system.
2. Principle of heat dissipation
When the coolant passes through the engine, the coolant temperature rises due to the high temperature generated by the engine. At this time, the coolant enters the upper tank of the radiator through the water inlet pipe, and flows to the lower tank along the channel inside the radiator. In this process, the coolant contacts the fins inside the radiator, so that the air inside the radiator is conducted by the coolant and takes it away. At the same time, during the driving process, the fan constantly drives the air through the surface of the radiator, which enhances the cooling effect of the air on the radiator. Finally, after such a series of complex physical processes, a large amount of heat generated by the engine is effectively removed.
3. Rectify the fault
If the engine temperature is abnormally high or the light is on, it is necessary to consider whether the radiator is faulty. Common fault causes include radiator blockage, water pump, fan damage, and so on, you need to check and maintain in time.
Four, radiator maintenance
1. Clean the radiator regularly: Because the car will inhale a lot of dust and impurities during the driving process, these impurities will accumulate in the radiator, affecting its heat dissipation effect. Therefore, it is recommended to clean the radiator every once in a while.
2. Check the pump: the pump is an important part of the coolant circulation system, if the pump powder is found, it needs to be replaced in time.
3. Check the fan: The fan is an important part of enhancing the cooling effect of air on the radiator. If the fan is found to be damaged, it needs to be replaced in time. 4. Replace the coolant regularly: the coolant is nie after a period of use, and may become inconsistent
Oxides in the air produce chemical reactions, resulting in reduced coolant performance. Therefore, it is recommended to replace the coolant at regular intervals.
V. Conclusion
The automobile radiator is an important part of the automobile cooling system, and its working principle is to remove the heat generated by the engine through the coolant circulation and heat dissipation principle. In order to ensure the normal operation of the car, it is necessary to carry out regular maintenance, including cleaning the radiator, checking the pump and fan, and replacing the coolant.
