We all know that diesel generator sets generate a large amount of heat during operation, and excessive heat can cause the temperature of the set to rise, thereby affecting work efficiency. Therefore, cooling systems should be equipped in the set to reduce the temperature of the set. There are two common cooling systems: water cooling and air cooling. The main difference between the two lies in the different cooling media. Air cooling, as the name suggests, uses wind as the cooling medium and directly cools the unit with wind. Water cooling uses water as the cooling medium, and then dissipates heat through a water tank and fan. Both functions are to dissipate heat into the air, and there is not much difference in usage.

Air cooled generator set:

A diesel engine is a generator with a single cylinder engine or a twin cylinder engine, and one to multiple large fans are used to forcibly exhaust and dissipate heat towards the generator body. Generally, gasoline generators and small diesel generators are the main types. Air cooled generator sets need to be installed in open cabins, resulting in high noise levels; The air-cooled generator unit has a simple structure, low failure rate, good starting performance, requires less air volume, consumes low fan power, and has low fuel consumption. There is no risk of frost cracking or overheating boiling, which is conducive to maintenance; Wind cooled generator sets are suitable for high-altitude, water scarce or cold areas, without considering issues such as water addition, boiling point, freezing, etc. Due to thermal and mechanical load limitations, the power is generally relatively small.

Water cooled generator set:

The diesel engine is mainly composed of four cylinder, six cylinder, twelve cylinder and other large units. The water circulation inside and outside the body takes away the heat generated inside the body through the radiator and fan. Water cooled power generation units are more common than large ones: the structure of water cooled power generation units is complex, the manufacturing difficulty is relatively high, and there are many requirements for the environment. When used in high-altitude areas, it is necessary to consider reducing power and lowering the boiling point of coolant water. A certain proportion of additives should be added to improve the boiling and freezing points; The cooling effect of water-cooled generator sets is ideal. Electric motors with the same technical parameters have a small volume, light weight, high energy density, and good heat transfer performance; High power generators are generally water-cooled.
