Cooling system for vehicle

A cooling system for a vehicle, comprising:

• an engine cooling device that circulates a coolant to an engine and cools the coolant in an engine radiator, the engine being provided with a turbocharger;
• an electrical equipment cooling device that circulates the coolant to an electrical equipment comprising a motor and an electric power component, and cools the coolant in an integral radiator;
• and
• an air conditioner comprising a water-cooled condenser that primarily condenses a refrigerant and an air-cooled condenser coupled in series to the water-cooled condenser that secondarily condenses the refrigerant and that cools or heats a vehicle interior through the refrigerant,
• wherein the water-cooled condenser is disposed within the integral radiator,
• a cooling module comprising the engine radiator, the integral radiator, and the air-cooled condenser is disposed at the front side of the vehicle and connected to the engine cooling device, the electrical equipment cooling device, and the air conditioner, and
• an intercooler mounted at an intake side of the engine uses the coolant to cool water and is connected to the electrical equipment cooling device,
• wherein the intercooler is disposed in parallel to the electrical equipment through a sub-cooling pipe that is connected to an electrical equipment cooling pipe disposed between the electrical equipment and the integral radiator;
• wherein the sub-cooling pipe is connected to the electrical equipment cooling pipe through a valve;
• and
• wherein the valve closes the electrical equipment cooling pipe when the vehicle is in an engine driving mode and the air conditioner is operated, and supplies coolant to the intercooler by connecting the sub-cooling pipe to a pipe connected to the integral radiator.
