1. An integrated thermal management system for a vehicle, the system comprising:
a refrigerant line provided with a compressor, a high-temperature core, an expansion valve, and a low-temperature core, wherein a refrigerant is circulated through the refrigerant line;
first coolant lines that circulate coolant and interconnect a first radiator, the high-temperature core, a heating core of an internal air conditioner, and a battery in parallel;
second coolant lines that circulate the coolant and interconnect a second radiator, an electronic driving part, the low-temperature core, and a cooling core of the internal air conditioner in parallel;
third coolant lines that circulate the coolant and interconnect a third radiator and the battery to the second coolant lines in parallel, and
wherein the battery is connected in parallel to upstream and downstream points of the heating core in the first coolant lines,
wherein the electronic driving part and the third radiator are connected in parallel to upstream and downstream points of the low-temperature core through the second coolant lines and the third coolant lines, and
wherein when battery heating and internal heating are required at a same time, the coolant that passed through the high-temperature core is branched and supplied to the battery and the heating core, and then the coolant that passed through the battery and the heating core joins and flows back into the high-temperature core, and the low-temperature core recovers waste heat through the second coolant lines and the electronic driving part, or recovers the waste heat through the third coolant lines and the third radiator.
