Classification of oil coolers

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

Air cooled

The core of the air-cooled 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.

Air Cooled oil cooler


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. 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 is also a structure in which the oil flows outside the tube and the water flows in the tube.

water cooled oil cooler


1:Engine oil cooler: Cool the lubricating oil of the engine, keep the temperature of the oil reasonable (90-120 degrees), and the viscosity is reasonable; the installation position is in the cylinder part of the engine, and it is installed integrally with the casing during installation.

2:Transmission oil cooler: Cooling the lubricating oil of the transmission, installed in the lower radiator of the engine radiator or outside the transmission case, if it is air-cooled, it is installed on the front side of the radiator.

3:Retarder oil cooler: the lubricating oil when the retarder works, the installation position is outside the gearbox

Side, mostly shell-and-tube or water-oil composite products.

4:Exhaust gas recirculation cooler: It is a kind of exhaust gas and device used to cool part of the return to the engine cylinder, in order to reduce the content of nitrogen oxides in the vehicle exhaust.

5:Cooling cooler module: It is a device that can simultaneously cool a variety of objects such as cooling water, lubricating oil, compressed air, etc., and the cooling module adopts a highly integrated design idea, which has the function of full volume and small intelligence. High performance features.

6:Air cooler, also known as the intercooler, is a device used to cool the high temperature and high pressure air after the engine is pressurized. By cooling the intercooler, the temperature of the charge air can be lowered, thereby increasing the density of the air to achieve engine power, fuel consumption and emissions.
