Zusammenfassung:	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 in a heat exchange unit 1; a branched flow path 20 branched from the circulation 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 in 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; a pressure sensor 70 for detecting the pressure of at least one of the upstream side and the downstream side of the circulation flow path 10; and a control unit 80 for driving the electric pump 60 under DUTY control to maintain the detection value of the pressure sensor 70 at a preset value.
