  • Cooling system for internal combustion engine
    Patent number: 11208944
    Abstract: The disclosure provides a novel cooling system for an internal combustion engine, which comprises a cooling fan, a first water radiator, an intercooler and a second water radiator, wherein the intercooler is positioned between the first water radiator and the second water radiator; the first water radiator is positioned at one end, close to an air inlet pipe, of an air inlet side of the intercooler, and the second water radiator is positioned at one end, close to an air outlet pipe, of an air outlet side of the intercooler; and the first water radiator, the intercooler and the second water radiator jointly form a heat exchange unit, and the cooling fan is provided on an outer side of the heat exchange unit. According to the disclosure, the heat exchange is more sufficient, the efficiency is higher, the water resistance is smaller, the cold air demand is less.
