Types of Engine Oil Coolers
Engine oil coolers can be generally classified into two types, such as oil-to-water and oil-to-air.
Oil-To-Water Cooler
In these types of oil coolers, the coolant passes through a heat exchanger element of some parts. The coolant is enabled either by adding heat to cold oil or drawing heat from excessively hot oil.
Oil-To-Air Cooler
is a small radiator that enables the engine oil to be cooled directly from ambient air from the cooling fans. Most of oil-to-air coolers work with a thermostatically controlled bypass valve that stops the engine oil from passing through the cooler without reaching its desired operating temperature. The various types of coolers include the basic tube-and-fin style, where the oil passes through a single or multiple coolers. Some other types may have multiple cooling rows or have a stacked plate type. Some oil coolers are header-style, where the end tanks are designed like a radiator.
