  • Dual circuit cooling systems
    Patent number: 5669338
    Abstract: This invention relates to a cooling system for a turbocharger engine having a first and a second fluid passing cooling circuits connected to a common radiator at spaced apart locations on the radiator. The first fluid passing cooling circuit circulates cooling fluid flow between the radiator and the engine and the second fluid passing cooling circuit circulates cooling fluid between an aftercooler and the engine. A temperature controlled valve in the first fluid passing circuit increases the cooling capacity of the second fluid passing circuit when closed or partially closed.
