1. A vehicle thermal management system comprising:
a heating heat exchanger which exchanges heat with air within an air-conditioning case to heat the air, and a cooling heat exchanger which exchanges heat with air to cool the air;
a refrigerant line circulating through a compressor, a condenser, an expansion valve, and a chiller;
a first coolant line containing a coolant that passes through the heating heat exchanger and exchanges heat with the condenser of the refrigerant line;
a second coolant line further containing the coolant that passes through the cooling heat exchanger and exchanges heat with the chiller of the refrigerant line;
a radiator;
a third coolant line further containing the coolant, the third coolant line passes through the radiator such that the radiator exchanges heat between the coolant and the outside air, and wherein the radiator exchanges heat with a battery of a vehicle;
a mixing tank provided to mix the coolant of the first coolant line, the second coolant line, and the third coolant line; and
wherein the mixing tank is a single unit that integrates a coolant storage function and a valve function.
