Thermal management system for vehicle

A thermal management system for a vehicle comprising a refrigerant cycle for carrying out air-conditioning of the interior of the vehicle, wherein a compressor for inhaling and compressing refrigerant and discharging the refrigerant in a gaseous state of high temperature and high pressure, a condenser for condensing the refrigerant by exchanging heat with the air, a first expansion valve for expanding the refrigerant, and an evaporator disposed inside an air-conditioning case to exchange heat between the refrigerant and the air discharged to the interior of the vehicle are disposed along a refrigerant line, which is a flow passage of the refrigerant;

• and
• wherein a cooling system of electronic components required for autonomous driving of the vehicle is connected to a first coolant line;
• wherein the electronic components are located along the first coolant line, and wherein a chiller is located along the first coolant line and along a refrigerant branch line branching off from the refrigerant line for exchanging heat between coolant in the first coolant line and refrigerant in the refrigerant branch line;
• wherein a coolant branch line is branched from the first coolant line at upstream and downstream sides of the electronic components such that the coolant branch line bypasses the electronic components, and wherein a battery is located along the coolant branch line;
• wherein a heater for heating the coolant is provided along the first coolant line downstream of the chiller, and a branch point of the first coolant line and the coolant branch line is formed on the downstream side of the heater such that the heater is located between the chiller and the branch point, and
• wherein a first valve is located at the branch point for selectively flowing the coolant toward the electronic components along the first coolant line and the battery along the coolant branch line to selectively pass coolant heated by the heater to the electronic components and the battery.
