Types of Oil Coolers: Typically involve a radiator-like structure with fins for air to pass over. Use a heat exchanger where hot oil and coolant flow in separate paths, transferring heat through the walls.
An oil cooler’s primary function is to remove excess heat from lubricating oil, ensuring it stays within an optimal temperature range for efficient operation and longevity. It works by transferring heat from the hot oil to a cooling medium, either air or a liquid like coolant, which then carries the heat away.
