There are two cooling methods for diesel generator sets: air cooling and water cooling.
1. Air Cooling
The air cooling method uses air as a cooling fluid to transfer heat from the heated parts of the diesel engine. The method consists of a cooling fan and a guide cover.
In order to increase heat dissipation neps, many corrugated fins are usually cast on the outer walls of the cylinder block, cylinder head and each radiator. During operation, the fan rotates to circulate air along the air guide cover to the surface of the cylinder block and cylinder head. As cold air passes through the heat sink, it carries away heat from the cylinder block and cylinder head.
2. Water cooling
The cooling methodWater heating uses water as a cooling fluid to transfer heat from heated parts of the diesel engine. The characteristic of this cooling method is that it is easy to adjust the cooling intensity when the temperature or workload changes.
There are two types of water cooling methods: open type and closed type. In an open cooling system, the circulating water is directly connected to the atmosphere and the steam pressure in the cooling system is always maintained at atmospheric pressure. In a closed system, water circulates in the closed system and the vapor pressure of the cooling system is greater than atmospheric pressure. As the temperature difference between the cooling water temperature and the outside air temperature increases, the heat dissipation capacity of the assembly increases. the cooling systemst improved.
