The difference between the cooling methods of diesel generators

Diesel generator sets will generate a lot of heat during normal operation. Excessive heat will cause the temperature of the engine to rise, which will affect the work efficiency. Therefore, a cooling system must be equipped in the unit to reduce the temperature of the unit. Common generator set cooling systems include water cooling and air cooling. Leton Power will introduce to you:

Air-cooled generator set: Use one or more large fans to force exhaust air to dissipate heat against the generator body. The advantages are simple construction, easy maintenance, and no danger of freeze cracking or overheating. The generator set is limited by thermal load and mechanical load, the power is generally small, and the power conversion rate of the generator set is relatively low, which is not energy-saving. The air-cooler must be installed in an open cabin, which has high environmental requirements and high noise, so it is necessary to do noise reduction in the computer room. The air cooling method is more used in small gasoline generators and low power diesel generator sets.

Water-cooled generator set: The water circulates inside and outside the body, and the heat generated inside the body is taken away through the cooling water tank and the fan. Both functions are to dissipate heat into the air, and there is not much difference in use. The advantages of the water-cooled unit are ideal cooling effect, rapid and stable cooling, and high power conversion rate of the unit itself. The installation site of the water-cooled unit is limited, the environmental requirements are small, the noise is low, and a remote cooling system can be realized. The water cooling method is generally used in small diesel generators and high-power diesel generator sets. Now the common diesel generator set brands on the market are Cummins, Perkins, MTU (Mercedes-Benz), Volvo Shangchai and Weichai are generally water-cooled generator sets.
