The system is composed of coolant preheater, preheating circulation pump, temperature regulating valves, cooling water pumps, heat exchangers, and an expansion tank. Each EDG has a separate, independent DGCWS, as shown in Figure 9.5.5-1—Emergency Diesel Generator Cooling Water System. 9.5.5.1 Design Basis
2023120·Air cooling system for portable diesel generator sets. The air cooling system uses high-speed air flow to blow directly over the outer surface of the cylinder head and cylinder block, and dissipates the heat from the inside of the cylinder to the atmosphere to ensure that the generator works within the most favorable temperature range.

Radiator cooling is the most common method of cooling gen set engines. Simple and practical, they fit most applications’ needs. All gen sets can be equipped with various sizes of radiators mounted on the front of the unit. However, remote radiators can be used when adequate airflow through the gen set enclosure is not possible.
Air-cooled systems are louder than liquid-cooled systems. The sound comes from the air the system blows over the engine to cool it. On the other hand, most liquid-cooling systems operate with low noise levels. Though all cooling systems and all generators do produce a good amount of noise overall.
Air-cooling systems are commonly used for standby & portable diesel generators in lower kW ratings and uses the circulation of air to bring down the temperature by drawing cool air from the atmosphere, then blowing it internally across different parts of the generator set.

However, remote radiators can be used when adequate airflow through the gen set enclosure is not possible.
Air cooling system can be used for open frame or enclosed diesel generator sets. In an open ventilation system, the atmosphere is used with a type of exhaust system. This allows the air to be released back into the atmosphere immediately. It sucks in air and pushes it back into the surrounding area.
202087·Let’s take a closer look at a few different kinds of marine generator cooling systems. Radiator Cooling. One very common type of cooling system is radiator cooling. A water jacket built around the generator allows coolant liquid to flow close to the machine, picking up heat.

201948·1. Closed System In a closed system, the coolant goes through the radiator (or another type of heat exchanger), which has enough surface area for ambient air (often blown by fans) to cool the liquid down. Usually, the radiator is located in the same enclosure as the generator itself, creating a small loop.
