THERMAL MANAGEMENT SYSTEM FOR VEHICLE

A thermal management system for a vehicle, which adjusts a temperature of a battery module by using one chiller that performs heat exchange between a refrigerant and a coolant and improves heating efficiency by using waste heat generated from an electrical component, includes: a cooling apparatus for circulating a coolant in a coolant line to cool at least one electrical component and an oil cooler provided in the coolant line; a battery cooling apparatus for circulating the coolant to the battery module; a chiller for heat exchanging the coolant with a refrigerant to control a temperature of the coolant; a heater that heats an interior of the vehicle using the coolant; and a first branch line, wherein a condenser included in the air conditioner is connected to the coolant line so as to allow the coolant circulating through the cooling apparatus pass therethrough.
