Thermal management system for vehicle

A thermal management system for a vehicle as a cooling system for cooling electronic components necessary for autonomous travelling of the vehicle, the thermal management system comprising:

• a first compressor for inhaling and compressing refrigerant and discharging out the compressed refrigerant in a gaseous state of high temperature and high pressure, a condenser for condensing the refrigerant, a first expansion valve for expanding the refrigerant, and a chiller for absorbing heat by exchanging heat between the refrigerant and coolant, which are disposed in a first refrigerant line in order,
• wherein the condenser is a water cooled condenser for radiating heat by exchanging heat between the refrigerant and the coolant,
• further comprising:
• a first coolant line passing through the chiller while exchanging heat with the electronic components;
• and a second coolant line, to which a low-temperature radiator for exchanging heat between the coolant and air is connected, and which passes through the water cooled condenser,
• wherein the coolant exchanges heat with the chiller of the first refrigerant line or exchanges heat with the air using the low-temperature radiator by being connected with the second coolant line.
