Multi-path cooling system and cooling system for eco-friendly vehicle applying the same
A multi path cooling system is provided that includes a first cooling path in which a refrigerant is circulated by a first pump and a second cooling path in which the refrigerant is circulated by a second pump. A reservoir tank is provided through which the refrigerant circulating through the first cooling path enters or exits. An air separator is disposed on the second cooling path to separate air from the passing refrigerant when the refrigerant circulating through the second cooling path passes. The reservoir tank and the air separator communicate with each other.
