High performance and temperature control of air-cooled engine oil coolers
Jun 22, 2018

The air-cooled engine oil cooler is a device that accelerates the heat dissipation of the lubricant oil so that it can maintain a relatively low temperature during operation. The air-cooled engine oil cooler is used in a high-performance, high-power enhanced engine due to heat. With large loads, oil coolers must be installed. The oil cooler is arranged in the lubricating oil circuit and works in the same way as the radiator.

The air-cooled engine oil cooler is mainly composed of a plurality of cooling pipes and cooling plates. When the car is running, it mainly uses the car facing air to cool the hot oil cooler core. Air-cooled oil coolers require good ventilation around them, and it is difficult to ensure adequate ventilation space in ordinary cars. They are rarely used. This type of cooler is mostly used on racing cars because of the high speed of the car and the large amount of cooling air.

The water-cooled engine oil cooler is placed in the cooling water circuit during operation. To a certain extent, the temperature of the cooling oil is mainly used to control the temperature of the lubricating oil. When the lubricating oil temperature is high, the cooling water reduces the temperature and the engine starts. The heat is absorbed from the cooling water so that the oil rapidly increases the temperature. The oil cooler is composed of a shell made of aluminum alloy, a front cover, a back cover, and a copper core tube. In order to enhance the cooling, the heat sink is set outside the tube. The cooling water flows outside the pipe, and the lubricating oil flows in the pipe. The two exchange heat. There are also structures that allow oil to flow outside the tube and water to flow inside the tube.
