What is a Oil cooler?

An oil cooler is a device that cools the engine oil of a car and the oil used in industrial machinery and maintains it at an appropriate temperature. In cars and motorcycles, it is also called a radiator, and in a broader sense it is called a heat exchanger. The viscosity of oil changes with its temperature. Viscosity has a large effect on oil performance, so the oil must be kept at a temperature that maximizes its performance. The oil cooler plays the role of cooling the oil to keep the oil at an appropriate temperature.
