The composition of cooler core: The oil cooler consists of an aluminum alloy cast casing, front cover, rear cover and copper core tube. In order to enhance cooling, heat sinks are installed on the outside of the tube. The cooling water flows outside the tube, the 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.
The function of cooler core: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 thermal load. When the engine is running, the lubricating capacity is reduced due to the thinning of the oil viscosity with increasing temperature. Therefore, some engines are equipped with oil coolers, 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.
The oil cooler is placed in the cooling water circuit, 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 the cooling water, and when the engine is started, the heat is absorbed from the cooling water to rapidly increase the temperature of the lubricating oil.
Cummins engines are mainly used in heavy vehicles, large buses, construction machinery, mining machinery, petroleum machinery, rail machinery, port machinery, fixed and mobile diesel generator set power station, marine propulsion power set and auxiliary power set.
