The function and principle of automobile radiator

1. Its function is to increase the heat dissipation area and accelerate the cooling of the coolant. In order to absorb the heat emitted by the radiator as soon as possible, install a fan behind the radiator and work with the radiator. Next, let's take a look at the function of car radiators with the editor of Auto Maintenance Technology Network.

2. Radiators play an irreplaceable and important role in auto parts, and maintenance is essential. At the same time, there must be enough heat dissipation area to complete the heat exchange between the antifreeze, air and radiator.The tubual radiator is welded by alternating corrugated heat dissipation strips and cooling tubes.

3. The function of automobile radiator is to store water and dissipate heat. The radiator is the main part of the cooling system. The purpose is to protect the engine from damage caused by overheating. The principle of the radiator is to use cold air to reduce the coolant temperature from the engine in the radiator.

4. The main function of the radiator is to lower the temperature of the coolant with a higher temperature through the heat dissipation pipe, so that the coolant can be restored to its original temperature, so as to play a cooling effect during the driving process of the car and the working process of the engine.

5. Principle of automobile radiators Automobile radiators are generally divided into water-cooled and air-cooled. As the name implies, air cooling achieves the effect of heat dissipation through the flow of cold air. OneThe general air-cooled cooler has a dense heat sink structure in the housing, which can help conduct heat and keep the engine temperature at a low level.

Detail the engine cooling system, what is the size cycle

1. [Pacific Automobile Network] Small cycle means that the engine coolant does not circulate through the water tank, but only through the cylinder head pipeline through the storage kettle. Alternate between cold and hot. The large cycle is when the temperature of the cooling water is higher than 80 degrees Celsius, the main valve of the thermosulator is fully open, the side valve is fully closed, and all the cooling water flows into the radiator, and the cooling intensity is large.

2. The small cycle of the engine cooling system is that the coolant only circulates in the waterway inside the engine, and the large cycle is that the coolant circulates through the radiator outside the engine, that is, the water tank.The switching of the two cycle modes is done through the thermosulator. When the thermostor is turned off, a small cycle is carried out, and vice versa, a large cycle is carried out.

3. The large circulation of the cooling system is the circulating flow of water through the radiator when the water temperature is high. As shown below: Control of large and small cycles: a thermoster is usually used to control the flow of cooling water through the radiator.

4. When the engine temperature reaches a certain value, the main valve will open and the coolant will pass through the radiator. At this time, the flow rate is large and the line is long, so it is called the large cycle. This great advantage of achieving precise control of the engine temperature is also the reason why the air cooling system is completely eliminated.

5. The following is the meaning of large and small circulation of the cooling system: when the temperature of the cooling water is higher than 86 degrees, the main valve of the thermoster is fully open, the side valve is fully closed, and all the cooling water flows into the radiator;At this time, the cooling intensity is high, which promotes the water temperature to drop without being too high.

working principle of automobile radiator

1. Working principle of radiator: The heat dissipation system of the water cooling system is It is composed of water pump, radiator, cooling fan, thermosulator, compensation water tank, engine cylinder block, cylinder head water sleeve and other components.The water pipes and heat sinks of the radiator are mostly made of aluminum. Aluminum water pipes are generally flat, and there are corrugated heat sinks between the cooling pipes.

2. Introduction to radiators: Principle: Most engines use internal combustion engines, and internal combustion engines rely on the thermal energy generated by combustion. However, the effective power is only 30% to 40% of the total fuel energy, and the rest of the energy is consumed as exhaust heat loss and mechanical friction heat loss.

3. Working principle of radiator: Water cooling system The cooling system is composed of water pump, radiator, cooling fan, thermostat, compensation water tank, engine body and water sleeve in the cylinder head and other parts. Radiator pipes and heat sinks are mostly made of aluminum. Aluminum tubes are generally flat, and there are corrugated heat sinks between the cooling tubes.
