What is the function of the automobile oil cooler, and what are the main parts composed of?

Composition of cooling system: In the whole cooling system, the cooling medium is coolant, and the main parts include thermosters, water pumps, pump belts,Radiator, cooling fan, water temperature sensor, liquid storage tank, heating device, expansion tank, water cover in engine body and cylinder head and other additional devices, etc.

The oil cooler is composed of an oil cooler cover cast in aluminum alloy and an oil cooler core welded by plate fins. The cooling water flows in the space of the oil cooler cover and the body siege, and the lubricating oil flows in the plate wings.

, because the oil has thermal conductivity and flows continuously in the engine, the oil cooler plays a cooling role on the engine crankcase, clutch, valve assembly, etc. Even if it is a water-cooled engine, the only parts that can be cooled with water are the cylinder head and the cylinder wall, and other parts still need to be cooled by the oil cooler.

Therefore, some engines are equipped with oil coolers, whose function is to reduce the oil temperature and maintain a certain viscosity of the lubricating oil.The oil cooler is arranged in the circulating oil line of the lubrication system.

The function and use of oil cooler

The function of oil cooler is What? As the name implies, the oil cooler can reduce the working temperature of the oil to make the oil temperature close to the ideal value. Generally, there are many automatic transmission vehicles.

The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal working range. On a high-power reinforced engine, an oil cooler must be installed due to the large heat load. When the engine is running, the lubrication ability is reduced because the viscosity of the oil becomes thinner with the increase of temperature.

What is the function of the oil cooler? As the name implies, the oil cooler can reduce the working temperature of the oil and make it close to the ideal value. Generally, there are many cars with automatic transmissions.

Many high-performance cars are organic oil coolers, which can reduce the temperature of the oil and ensure the lubrication effect of the oil. It is recommended that you change the oil on time when using the car. If the oil is used for a long time, the performance in all aspects will decrease, so the oil should be changed regularly. If the oil is not changed for a long time, it will aggravate the wear of the engine.

The gasoline cooler functions as follows: the main work of the cooling system is to dissipate heat into the air to prevent the engine from overheating, but the cooling system has other important roles.

Where is the installation location of the oil cooler?

1. Where is the oil cooler? Most of the oil coolers are basically under the oil filter. The advantages are as follows: Most automatic transmission vehicles are equipped with oil coolers. The cooling oil is thicker than high-temperature oil, which can improve the lubrication performance. Reducing the working temperature of parts is conducive to prolonging the service life of parts.

2. Installed on the engine cylinder block waterway or on the oil filter seat, these two are water-cooled. There is also an air-cooled one installed in the middle mesh part, which requires a temperature switch to control the oil, and only when the oil temperature is high will it flow through the radiator.Oil radiator is also known as oil cooler. It is an oil cooling system applied to diesel engines.

3. The oil cooling valve of Nanjing Iveco Osheng 0t engine is generally under the oil filter. Oil cooler is a device that accelerates the heat dissipation of lubricating oil to keep it at a lower temperature. On high-performance and high-power reinforced engines, oil coolers must be installed due to the large heat load.

4. The installation position of the Audi Q7 oil radiator is behind the big mark of the car and in front of the engine. The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal working range. On a high-power reinforced engine, an oil cooler must be installed due to the large heat load.

5. The oil cooler should be cleaned regularly. When reinstalling, the oil seal should be kept flat and in the correct position.Aging or sticky oil seal should be replaced with a new one, otherwise it will cause oil and water mixing and lead to diesel engine failure.

6. Four hexagon nuts are fixed, and there are two rubber rings on the fitting surface. Flat glue is applied during installation. Installed in the cooling cover, on the left side of the engine. When disassembling and installing, use a sharper object to pick out the rust and then put the hexagon wrench in and tap it with a hammer to reduce the chance of writching.

What is the working principle of oil cooler?

1. One of the oil coolers. Accelerate the heat dissipation of the lubricating oil and keep it at a lower temperature device. On the high-capacity high-power turbocharged engine, an oil cooler must be installed due to the large heat load. The oil cooler is set in the lubricating oil circuit. Its working principle is the same as that of the radiator.

2. The oil cooling machine uses the evaporation and heat absorption principle of refrigerant to carry out cooling work.

3. The main work of the cooling system is to dissipate heat into the air to prevent the engine from overheating, but the cooling system has other important roles.

4. The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal working range. On a high-power reinforced engine, an oil cooler must be installed due to the large heat load. When the engine is running, the lubrication ability is reduced because the viscosity of the oil becomes thinner with the increase of temperature.
