Abstract: A vehicle thermal management system including a heating heat exchanger which exchanges heat with air within an air-conditioning case to heat the air, and a cooling heat exchanger which exchanges heat with air to cool the air; a refrigerant line circulating through a compressor, a condenser, an expansion valve, and a chiller; a first coolant line that passes through the heating heat exchanger and exchanges heat with the condenser of the refrigerant line; a second coolant line that passes through the cooling heat exchanger and exchanges heat with the chiller of the refrigerant line; a radiator that exchanges heat between the coolant and outside air; a third coolant line that passes through the radiator and exchanges heat with a battery of a vehicle; and a mixing tank provided to mix the coolant of the first coolant line, the second coolant line, and the third coolant line.

Abstract: A heat management system including a refrigerant circulation line including a compressor, a water-cooling condenser, an air-cooling condenser, a first expansion valve, an evaporator, a refrigerant heat exchanger, and a gas/liquid separator that discharges only a liquid refrigerant, and cooling an indoor place by circulating a refrigerant; a heating line for heating the indoor place by circulating, through the water-cooling condenser, cooling water that exchanges heat with the refrigerant; and a cooling line for cooling a battery and an electrical component by circulating air or cooling water that exchanges heat with the refrigerant. Therefore, the present invention can not only cool and heat a vehicle but also efficiently manage heat for an electrical component and a battery in a vehicle, and can reduce the number of constituent components for heating and cooling.

Abstract: An embodiment of the present invention provides a vehicle heat pump system including a compressor configured to compress and circulate a refrigerant, a condenser configured to condense the compressed refrigerant, a first expansion valve configured to expand the condensed refrigerant, an evaporator configured to evaporate the refrigerant expanded by the first expansion valve by allowing the refrigerant to exchange heat with a coolant, a cabin cooler configured to cool a vehicle interior by allowing the coolant having passed through the evaporator to exchange heat with air, and a radiator configured to allow the coolant for cooling an electrical component to exchange heat with outside air, in which the coolant having passed through the radiator flows into the evaporator in a heating mode.
