摘要： A cooling system includes a fluid circuit and a cooler arranged in fluid communication with said fluid circuit. The cooler regulates the temperature of said coolant. The fluid circuit comprises a first coolant fluid branch for circulating coolant to regulate a temperature of a low temperature component and a second coolant fluid branch for circulating coolant to regulate a temperature of a high temperature component. A first pump unit is arranged in said first coolant fluid branch. A coolant temperature control system is disposed in said first coolant fluid branch and regulates a temperature of the coolant to the low temperature component on the basis of a temperature difference between a coolant temperature upstream the coolant temperature control system and a temperature required at an inlet of the low temperature component. A second pump unit is arranged in said second coolant fluid branch, and directs coolant to said high temperature component; wherein the second coolant fluid branch intersects with the first coolant fluid branch at a fluid circuit position downstream the low temperature component.
