Cooling is needed because high temperature damages engine materials and lubricants. Internal-combustion makes engine hotter than the melting temperature of engine materials, and hot enough to set fire to lubricants. Engine cooling removes energy fast enough to keep temperatures low so the engine can survive. Air cooling and water cooling are two means that usually adopted by gensets. The advantages of using water cooling over air cooling include water's higher specific heat capacity, density, and thermal conductivity. As opposed to air cooling, water is used as the heat transmitter. This allows water to transmit heat over greater distances with much less volumetric flow and reduced temperature difference.
In torrid area, water cooling is more efficient at controlling the water temperature and it even ensures the gensets work well at 85-90℃.
