① Engine oil cooler: cools the lubricating oil of the engine, keeps the oil temperature reasonable (90-120 degrees), and the viscosity is reasonable; the installation position is in the cylinder block of the engine, and it is installed integrally with the housing during installation.
②Transmission oil cooler: It cools the lubricating oil of the transmission. It is installed in the radiator of the engine or outside of the transmission case. If it is air-cooled, it is installed on the front side of the radiator.
③ Retarder oil cooler: cools the lubricating oil when the retarder is working, and is installed outside the gearbox
On the other hand, they are mostly shell-and-tube or water-oil composite products.
④ Exhaust gas recirculation cooler: It is a device used to cool part of the exhaust gas returned to the engine cylinder, the purpose is to reduce the content of nitrogen oxides in the exhaust gas of the car.
⑤ Radiating cooler module: It is a device that can simultaneously cool multiple objects or some objects such as cooling water, lubricating oil, compressed air, etc. The cooling module adopts a highly integrated design idea, and has a full-featured, small-sized and intelligent High performance characteristics.
⑤Air cooler, also called intercooler, is a device used to cool the high temperature and high pressure air after the engine is supercharged. Through the cooling of the intercooler, the temperature of the supercharged air can be reduced, thereby increasing the density of the air, in order to achieve the purpose of engine power, fuel consumption and emission reduction.
