Patent attributes
A heat management system which includes: a refrigerant circulation line which includes a compressor, a water cooling-type condenser, a first expansion valve, an air cooling-type condenser, a second expansion valve, and an evaporator, and cools the indoor space by circulating a refrigerant; a heating line which heats the indoor space by circulating cooling water which exchanges heat with the refrigerant through the water cooling-type condenser; a first cooling line which cools a battery by circulating cooling water which exchanges heat with air or the refrigerant; and a second cooling line which cools electric components including a driving motor, by circulating cooling water which exchanges heat with air or the refrigerant. The heat management system enables efficient heat management of electric components and a battery in a vehicle as well as cooling and heating of the vehicle.
