1. An integrated thermal management apparatus for vehicles, the apparatus comprising:
a refrigerant line to which a compressor, a refrigerant heater, an internal condenser, an integrated chiller and an external condenser are mounted, wherein a refrigerant sequentially flows from the compressor to the refrigerant heater through the refrigerant line and the refrigerant discharged from the refrigerant heater passes through the internal condenser of an indoor air conditioning apparatus or the integrated chiller and then flows into the external condenser, and the refrigerant discharged from the external condenser passes through the integrated chiller or an evaporator of the indoor air conditioning apparatus and then flows into the compressor;
a battery cooling line, to which a battery, an integrated radiator and the integrated chiller are mounted, wherein a coolant circulates between the battery and the integrated radiator or between the battery and the integrated chiller;
an electronic part cooling line, to which an electronic driving unit, the integrated radiator and the integrated chiller are mounted, wherein the coolant circulates between the electronic driving unit and the integrated radiator or between the electronic driving unit and the integrated chiller; and
a heat radiation control valve provided between the refrigerant heater and the internal condenser on the refrigerant line and configured to adjust a flow rate of the refrigerant flowing into the internal condenser to control an amount of heat radiated by the internal condenser during heating of an interior of a vehicle,
wherein the refrigerant heater heats the refrigerant discharged from the compressor and supplies the heated refrigerant to the internal condenser, and the heat radiation control valve is configured to control a temperature of the refrigerant supplied to the internal condenser by adjusting a flow rate of the heated refrigerant.
