Both heat exchangers and oil coolers are components used in marine cooling systems, but they serve different purposes and operate under different conditions.
A heat exchanger is a device that transfers heat from one fluid to another without the fluids mixing. In a boat engine, the heat exchanger is used to transfer heat from the engine's coolant to the raw water that is circulated through the engine's cooling system. The raw water absorbs the heat and is then discharged back into the water. This process allows the engine to maintain a stable operating temperature and prevents overheating. Heat exchangers are typically made of materials that are resistant to corrosion, such as copper or stainless steel.
An oil cooler is also a component that transfers heat from one fluid to another without the fluids mixing. Generally these are designed to cool the engine oil, transmission or gear oil, fuel, hydraulic fluid or power steering. It operates by circulating the oil around a series of fins or tubes while raw water runs through the tubes. It is always this way probably because the raw water is not nearly as clean of a fluid as the lube fluids. The cooled oil is then returned to do it’s job. The purpose of an engine oil cooler is to prevent overheating, which can cause the oil to break down and lose its lubricating properties. This is also true for the power steering and transmission coolers. Fuel is cooled to prevent vapor lock and also to increase the fuel density in turn increasing the fuel package delivered to the cylinder increasing horsepower and more complete use of the fuel package delivered.
Oil coolers are typically made of materials that are resistant to corrosion such as copper and brass in the marine industry.
In summary a heat exchanger and oil cooler are made in much the same manner. They are used in slightly differing circumstances. A heat exchanger is used to transfer heat from the engine coolant to raw water, while an oil cooler is used to cool the engine ‘s various types of oil. Both components play important roles in keeping the engine operating at a safe and optimal temperature commonly around 177F.
