How the oil cooler works
Release time:
2023-10-09
The function of the oil cooler is to cool the lubricating oil and keep the oil temperature within the normal operating range. On high-power reinforced engines, due to the large thermal load, an oil cooler must be installed. When the engine is running, as the viscosity of the engine oil becomes thinner as the temperature increases, the lubrication ability is reduced. Therefore, some engines are equipped with an oil cooler, whose function is to reduce the temperature of the oil and maintain a certain viscosity of the lubricating oil. The oil cooler is arranged in the circulating oil circuit of the lubrication system, and its working principle is the same as that of the radiator.

Types of oil coolers
1. Air-cooled oil cooler The air-cooled oil cooler is much like a small radiator. The core of the cooler is composed of many cooling tubes and cooling plates. It uses the head wind when the car is driving to cool the oil. This kind of oil cooler has a large heat dissipation capacity and is mostly used in racing cars and supercharged cars with large heat loads. However, air-cooled oil coolers require a long warm-up time after the engine is started to allow the oil to reach normal operating temperature, so they are rarely used in ordinary cars.
2. Water-cooled oil cooler The oil cooler is placed in the cooling water circuit and uses the temperature of the cooling water to control the temperature of the lubricating oil. When the temperature of the lubricating oil is high, it is cooled by the cooling water. When the engine is started, heat is absorbed from the cooling water to quickly increase the temperature of the lubricating oil. The oil cooler is composed of an aluminum alloy cast housing, a front cover, a rear cover and a copper core tube. In order to enhance cooling, heat sinks are installed outside the tube. Cooling water flows outside the tube, lubricating oil flows inside the tube, and the two exchange heat. There are also structures that allow oil to flow outside the tube and water to flow inside the tube.

What are the classifications of oil coolers?
Engine oil cooler: Cools the engine's lubricating oil and keeps the oil at a reasonable temperature (90-120 degrees) and a reasonable viscosity. It is installed in the cylinder of the engine and is installed integrally with the casing during installation.

What kind of oil cooler do you know
The oil cooler is placed in the cooling water channel and the temperature of the cooling water is used to control the temperature of the lubricating oil.When the temperature of lubricating oil is high, cooling water is used to cool the oil. When the engine starts, heat is absorbed from the cooling water to rapidly increase the temperature of lubricating oil.The oil cooler is composed of aluminum alloy shell, front cover, back cover and copper core pipe.In order to strengthen the cooling, the outer tube is equipped with a radiator.Cooling water flows outside the pipe and lubricating oil flows inside the pipe.There are also structures that allow oil to flow outside the pipe and water to flow inside.

One is the air-cooled type. The core of the air-cooled oil cooler is composed of many cooling tubes and cooling plates. When the car is driving, the car's headwind is used to cool the hot oil cooler core. The air-cooled oil cooler requires good ventilation around it. It is difficult to ensure sufficient ventilation space in ordinary cars, so it is rarely used. This type of cooler is mostly used in racing cars because the racing speed is high and the cooling air volume is large.
