Use outside air to cool the air passing through the intercooler. The advantage is that the entire cooling system has fewer components and the structure is relatively simpler than that of a water-cooled intercooler. The disadvantage is that the cooling efficiency is lower than that of the water-cooled intercooler, and generally requires a longer connection pipeline, and the air passage resistance is larger.
2. Water-cooled intercooler
Use circulating cooling water to cool the air passing through the intercooler. The advantage is that the cooling efficiency is higher, and the installation position is more flexible, and there is no need to use a long connecting pipeline, which makes the entire intake pipeline smoother. The disadvantage is that a circulating water system that is relatively independent from the engine cooling system is required to cooperate with it. Therefore, the entire system has more components, higher manufacturing costs, and complex structure.
