Stable performance: The petrol oil cooler pipe reduces the temperature of the oil, reduces oxidation and and extends the life of the oil. Air-cooled oil coolers are assembled from a large number of cooling tubes and radiator plates, leveraging the natural airflow created by vehicle movement to dissipate heat from the high-temperature oil passing through the cooler core. Water-cooled oil coolers are commonly composed of an aluminum alloy outer casing, two end covers at the front and rear, and core tubes made of copper, with cooling fins arranged on the exterior of the tubes to improve cooling performance., Manufacturer: PUAYWMOZ
