Auto Radiator - the Safety Protector of Your Car

When car Engine is working, fuel combustion makes the temperature of the gas in cylinder reach up to 2200 K to 2800K (1927℃~ 2527℃), and only about 1/3 of the heat is turn into mechanical energy. Most of the rest heat is discharged with the exhaust gas, and another small part is absorbed by the engine parts. So the temperature of engine parts rises, especially the parts that have direct contact with the high temperature gas. If these parts are not promptly cooled, it is difficult to ensure that the engine work properly.

Automotive engine cooling system mainly based on water cooling. The circulating water in the cylinder waterway take charge of cooling the heat, then the heated water is introduced to the radiator. After air cooling, the heated water returns to the waterway. In order to ensure the cooling effect, in general, the automotive cooling system is mainly composed by the radiator, thermostat, water pumps, cylinder waterway, cylinder head waterways, and fan.

The auto radiator is the key components of the engine cooling system. By forced water circulation to cool the engine, it ensures that the engine continuously work in a normal temperature range.

The auto radiator is composed of upper water ventricle, the radiator core and down water ventricle. The most common auto radiator can be divided into two kinds: gilled tube radiator and ribbon-tubular radiator. And there are two kinds of radiator core: gilled tube radiator core and ribbon-tubular radiator. Gilled tube radiator core is composed by many fine cooling pipes and cooling fins. Most cooling pipes use oblate cross section to reduce the air resistance and increase the heat transfer area. The radiator core not only has sufficient liquid flow area that allow cooling liquid pass through, but also has enough air flow area that allow a large amount of air pass through to take away the heat of the radiator. Ribbon-tubular radiator is welded by corrugated radiating belt and cooling pipe and they are arranged alternately. Compared with the gilled tube radiator, the cooling area of Ribbon-tubular radiator can be increased about 12%. It can increase the auto radiator's cooling effect.

When a car is running, the heat produced by car engine is enough to destroy the car. So a cooling system is installed in it to prevent it from the damage, and the auto radiator in the cooling system can keep the car engine stays in a proper temperature range. Cooling system problems happen mainly on the car which has already run for five years or over five years. They may occur in an unexpected time. These cars have been used for a long time, so their cooling system may be damaged. The salt in the sea air, road salt, debris and other chemicals will damage the metal materials of the radiator, and the direct consequence of it is engine overheating, while overheating makes the engine always exist the danger of explosion. So to know the knowledge of auto radiator and properly maintain it can keep your car's safety.
