The core of an air-cooled oil cooler consists of many cooling tubes and cooling plates. When the car is driving, the hot oil cooler core is cooled by the wind blowing in front of the car. Air-cooled oil coolers require good ventilation around them. It is difficult to ensure sufficient ventilation space in ordinary cars, so they are rarely used. This type of cooler is mostly used in racing cars because the racing car has a high speed and a large cooling air volume.

Cars with automatic transmissions must be equipped with a transmission oil cooler because the oil in the automatic transmission may overheat. Overheating of the oil will reduce the performance of the transmission and even cause damage to the transmission. The transmission oil cooler is usually a cooling pipe placed in the water outlet chamber of the radiator. The coolant cools the transmission oil flowing through the cooling pipe. A metal pipe or rubber hose is used to connect the transmission and the cooler.
The oil cooler is a device that accelerates the heat dissipation of lubricating oil to keep it at a lower temperature. The purpose of installing this device is to prevent the lubrication effect from weakening due to the increase in oil temperature. According to the different cooling media, oil coolers can be divided into air-cooled and water-cooled types. The air-cooled type uses the airflow generated when the vehicle is running to cool the oil. The water-cooled type is usually installed in the water chamber of the car's radiator or in a separately circulating cooling water system to cool the high-temperature oil through heat exchange with the cooling water.
