PROBLEM TO BE SOLVED: To provide a cooling system that can efficiently cool a heat exchange unit even when an electric pump is used.SOLUTION: A cooling system 100 includes: a circulation flow path 10 for circulating a refrigerant to a heat exchange unit 1; a branch flow path 20 branched from the circulation flow path 10 and joining the circulation flow path 10 after distribution of the refrigerant to a sub heat exchange unit 2 disposed in parallel with the heat exchange unit 1; a valve 50 disposed in the branch flow path 20 to set the flow rate of the refrigerant distributed through the branch flow path 20; an electric pump 60 for supplying the refrigerant to the circulation flow path 10 and the branch flow path 20; and a control unit 80 for driving the electric pump 60 under DUTY control based on opening degree information indicating the opening degree of the valve 50. |
