According to the manufacturer of automobile radiator, automobile radiator is a device that mainly relies on the rotation of the engine to drive the water pump to circulate the cooling water in all parts of the engine and emit water heat during the circulation process. The principle of automobile radiator is to prevent the engine from overheating and ensure the cooling effect. The parts around the combustion chamber (cylinder liner, cylinder head, valve, etc.) must be properly cooled.

The manufacturer of automobile radiator warmly reminds that automobile radiator is an indispensable and important part in the cooling system of automobile water-cooled engine, and is developing in the direction of light weight, high efficiency and economy. The structural design of automobile radiator may not be able to adapt to the new development. The core of tubular radiator is composed of many thin cooling tubes and fins. Most of the cooling tubes adopt flat circular sections to reduce air resistance and increase heat transfer area, The radiator core should have enough circulation area to allow the antifreeze to pass through, and at the same time, it should have enough air circulation area to allow enough air to pass through and take away the heat transferred by the antifreeze to the radiator. At the same time, there must be enough heat dissipation area to complete the heat exchange between antifreeze, air body and radiator. The tubular radiator is made of corrugated heat dissipation strip and cooling pipe alternately welded. Compared with the tubular radiator, the tubular radiator can increase the heat dissipation area by about 12% under the same conditions. In addition, the heat dissipation belt is also equipped with holes similar to louvers, which will disturb the air flow and damage the attachment layer of flowing air on the surface of the heat dissipation belt, Improve heat dissipation.

How to maintain the car radiator? The manufacturer of automobile radiator will introduce it to you.

1. The heat sink shall not contact with any acid, alkali or other corrosive properties.

2. The manufacturer of automobile radiator suggests to use soft water. The hard water should be softened before use to avoid internal blockage and scale in the radiator.

3. When using antifreeze, in order to avoid the corrosion of the radiator, it is necessary to use the anti-rust and long-acting antifreeze from the regular manufacturer and the national standard.

4. In the process of installation and use, please do not damage the diffuser (fin) and bruise the radiator to ensure the technical capacity and sealing of the system.

5. When the radiator is completely drained and then filled with water, first turn on the drain switch of the engine body, and then turn off when there is water flowing out to avoid blistering.

6. In daily use, check the water level from time to time, and add water to cool down after stopping. When adding water, slowly open the water tank cover, and try to keep the operator's body away from the water inlet to prevent scalding by high-pressure steam from the water inlet.

7. In winter, in order to prevent the core from freezing and cracking due to long-term or indirect shutdown, the water tank cover and drain switch should be used to drain all the water.

8. The effective environment of the standby radiator should be kept ventilated and dry.

9. The manufacturer of automobile radiator suggests that the user should completely clean the radiator core once within 1~3 months according to the actual situation. When cleaning, use clean water to wash along the air direction behind.

10. The water level gauge shall be cleaned once every three months or depending on the actual development, all parts can be removed and cleaned with warm water and non-corrosive detergent.
