HS code accuracy for automotive exports

Engine radiator: effectively reduce the engine temperature With the continuous development of automobile technology,HS code accuracy for automotive exports the power, comfort and safety of automobiles have been continuously improved. As the "heart" of the car, the engine's performance, life and safety are inseparable from the overall performance of the vehicle. As an important part of the engine, the engine radiator plays a crucial role in the stable operation of the engine. I. The function and principle of the engine radiator. The engine generates a large amount of heat during operation, which will seriously affect the performance and life of the engine if it is not emitted in time. Therefore, the function of the engine radiator is to radiate the heat generated by the engine to ensure that the engine will not overheat.The engine radiator is a heat exchanger. Its principle is to exchange heat with air through the water in the radiator to achieve the purpose of heat dissipation. II. Types of engine radiators The types of engine radiators are mainly divided into the following types: 1. DC radiator DC radiator is a common type of radiator. Its simple structure, high reliability, easy maintenance and other characteristics are widely favored by automobile manufacturers. The heat dissipation effect of the DC radiator is not very good, but it is good under low-load conditions. Two. The structure of transverse-flow radiators is different from that of DC radiators, and their heat dissipation effect is better than that of DC radiators. There are relatively many heat sinks in the transverse radiator, which can improve the efficiency of heat exchange, so that it has a good heat dissipation effect under various working conditions. 3.Reflow radiator Reflow radiator adopts hot water return for heat dissipation, which can effectively improve the heat dissipation efficiency and is suitable for engines under high power and high load conditions. III. The method of maintaining the engine radiator. In the process of daily use, the engine radiator also needs to be maintained to ensure its normal operation. Some maintenance methods are as follows: 1. Regular cleaning of the engine radiator. During use, the engine radiator will deposit a certain amount of dust and oil. If it is not cleaned for a long time, it may cause a decrease in the heat dissipation effect. Therefore, it is very necessary to clean the engine radiator regularly. Two. Impurities, bubbles, silicon caused by rust, etc. in the circulation of the coolant and coolant will enter the engine radiator. If it is not replaced in time, it will affect the heat dissipation effect.3. Check the tightness of the engine radiator. If the tightness of the radiator is not good, it may cause leakage of coolant, thus affecting the normal operation of the engine. Therefore, it is necessary to check the tightness of the radiator regularly. IV. Precautions: Some things need to be paid attention to in the process of using the engine radiator: 1. Repair in time when a failure occurs to avoid more failures. Two. When adding lights and other accessories to the engine, it is necessary to pay attention to whether it will affect the heat dissipation of the engine, etc. 3. When exercising the vehicle for a long time, you should regularly check whether the engine cooling system is normal to avoid engine overheating caused by system failure. In a word, the engine radiator is an important part of the car, which is very important for the stable operation and long-term use of the engine. Therefore, in the process of using a car, when it is found thatWhen the motive radiator fails or is abnormal, it should be dealt with in time to ensure the normal operation of the car. At the same time, it should be maintained and maintained regularly to ensure the performance and service life of the radiator.
