Lubricating oil water temperature and performance of engineering machinery oil cooler

- Jun 24, 2019-

The engineering machinery oil cooler is a device that accelerates the lubrication of the lubricating oil to keep it at a lower temperature during the working process. On the high-performance, high-power reinforced engine, the oil cooler must be installed due to the large heat load. The oil cooler is arranged in the lubricating oil circuit and works in the same way as the radiator.


The core of the engineering machinery oil cooler consists of a number of cooling tubes and cooling plates that are used to cool the hot oil cooler cores while the car is running. Air-cooled oil coolers require good ventilation around, and it is difficult to ensure adequate ventilation in ordinary cars, which is rarely used. Most of these coolers are used in racing cars because of the high speed of the car and the large amount of cooling air.


The water-cooled type of the construction machinery oil cooler 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, the heat is absorbed from the cooling water to rapidly increase the temperature of the lubricating oil. The oil cooler consists of a shell made of aluminum alloy, a front cover, a back cover and a copper core tube. In order to enhance the cooling, a heat sink is placed outside the tube. The cooling water flows outside the tube, and the lubricating oil flows in the tube, and the two exchange heat. There are also structures that allow oil to flow outside the tube while the water flows inside the tube.
