Thermal management system for vehicle

1. A thermal management system for a vehicle, comprising:

a cooling apparatus configured to circulate a coolant cooled in a radiator through a coolant line to cool a driving device provided in the vehicle;

a main centralized energy (CE) module connected to the cooling apparatus via the coolant line and configured to selectively heat-exchange thermal energy generated during a condensation and evaporation of a first refrigerant circulating therein with the coolant and respectively supply the coolant of a first low temperature or a high temperature to at least a cooling heat exchanger or a heating heat exchanger; and

a sub CE module connected to the cooling apparatus via the coolant line and configured to selectively heat-exchange thermal energy generated during a condensation and evaporation of a second refrigerant circulating therein with the coolant and supply the coolant of a second low temperature to a controller provided in the vehicle.

2. Thermal management system for the vehicle of claim 1 , wherein the main CE module includes:

a first compressor configured to compress the first refrigerant;

a first condenser connected to the first compressor via a first refrigerant line and configured to heat-exchange the compressed first refrigerant supplied from the first compressor with the coolant supplied therein through the coolant line to be condensed;

a first expansion valve connected to the first condenser through the first refrigerant line and configured to expand the first refrigerant; and

a first evaporator connected to the first expansion valve via the first refrigerant line, connected to the cooling heat exchanger circulating the coolant through the cooling line, evaporating the first refrigerant supplied from the first expansion valve with the coolant received through the air-conditioning line through the heat exchange, and supplying an evaporated refrigerant to the first compressor.

3. Thermal management system for the vehicle of claim 2 , wherein the first condenser is connected to the heating heat exchanger via a heating line and configured to supply the coolant of which the temperature increases while condensing the first refrigerant to the heating heat exchanger through the heating line.

4. Thermal management system for the vehicle of claim 3 , wherein a third water pump configured to circulate the coolant to the heating heat exchanger and the first condenser is provided in the heating line.

5. Thermal management system for the vehicle of claim 2 , wherein the first evaporator is configured to supply the coolant of which the temperature decreases while evaporating the first refrigerant through the heat exchange with the coolant to the cooling heat exchanger through the cooling line.

6. Thermal management system for the vehicle of claim 2 , wherein a second water pump configured to circulate the coolant to the cooling cooler and the first evaporator is provided at the cooling line.

7. Thermal management system for the vehicle of claim 1 , wherein the sub CE module includes:

a second compressor configured to compress the coolant;

a second condenser connected to the second compressor via a second refrigerant line and configured to heat-exchange the compressed coolant supplied from the second compressor with the coolant supplied therein through the coolant line to be condensed;

a second expansion valve connected to the second condenser through the second refrigerant line and expanding the second refrigerant; and

a second evaporator connected to the second expansion valve via the second refrigerant line, connected to the controller via a connecting line, configured to evaporate the second refrigerant supplied from the second expansion valve with the coolant received through the connecting line through the heat exchange, and supply the evaporated refrigerant to the second compressor.

8. Thermal management system for the vehicle of claim 7 , wherein the second evaporator is configured to supply the coolant of which the temperature decreases while evaporating the second refrigerant through the heat exchange with the coolant to the controller through the connecting line.

9. Thermal management system for the vehicle of claim 7 , wherein a fourth water pump is provided in the connecting line.

10. Thermal management system for the vehicle of claim 1 , wherein the cooling apparatus further includes a first water pump provided in the coolant line and configured to circulate the coolant cooled in the radiator.

11. Thermal management system for the vehicle of claim 1 , wherein the first refrigerant circulating in the main CE module and the second refrigerant circulating in the sub CE module is R152-a, R744, or R290.
