Zusammenfassung:A cooling system of a hybrid electric vehicle (HEV) includes an engine cooling circuit that cools cooling water using an engine heat exchanger and circulates the cooled cooling water using an engine water pump to cool an engine. An HEV cooling circuit cools cooling water using an HEV heat exchanger and circulates the cooled cooling water using an HEV water pump to cool an inverter and a motor. A connection part connects the engine cooling circuit to the HEV cooling circuit.
