the oil cooler must be installed because of the high heat load. When the engine is running, the lubrication capacity is reduced because the oil viscosity becomes thinner as the temperature rises.
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 oil.
The oil cooler is arranged in the circulating oil line of the lubrication system. The core of the air-cooled oil cooler is composed of many cooling tubes and cooling plates.
When the car is running, the hot oil cooler core is cooled by the car's head-on air. Air cooled oil cooler requires good ventilation around, and it is difficult to ensure sufficient ventilation space on ordinary cars,
so it is rarely used. This type of cooler is mostly used on racing cars because of the high speed and high cooling air volume. 2) water-cooled oil cooler 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 the lubricating oil is high, it is cooled by cooling water.
When the engine starts, heat is absorbed from the cooling water to rapidly raise the temperature of the lubricating oil. The oil cooler is composed of aluminum alloy shell, front cover,
back cover and copper core tube. In order to enhance cooling, a heat sink is fitted outside the tube. Cooling water flows outside the pipe, and lubricating oil flows inside the pipe,
and the two exchange heat. There are also structures that allow oil to flow outside the tube and water to flow inside the tube.
