A cooling system for a vehicle is provided. The cooling system includes a condenser having a first inlet header, a first outlet header, and a plurality of first tubes connecting between the first inlet header and the first outlet header. Additionally, a radiator of the system includes a second inlet header, a second outlet header, and a plurality of second tubes connecting between the second inlet header and the second outlet header. A fan assembly is disposed in front of or behind the condenser and the radiator and includes at least one cooling fan. The condenser and the radiator are arranged side by side on the front of the vehicle.

A heat exchanger group includes a first heat exchanger, a second heat exchanger, and a third heat exchanger. In a cooling operation, refrigerant discharged from the compressor is divided into two. One refrigerant is delivered to the second heat exchanger, and the other refrigerant is delivered to the third heat exchanger. The second heat exchanger performs heat exchange to turn the refrigerant into two-phase refrigerant. The third heat exchanger performs heat exchange to turn the refrigerant into two-phase refrigerant. The refrigerant that has flowed through the second heat exchanger and the refrigerant that has flowed through the third heat exchanger meet, and the resultant refrigerant is delivered to the first heat exchanger. The first heat exchanger performs heat exchange, so that the two-phase refrigerant turns into liquid refrigerant and flows through the first heat exchanger.
