PROBLEM TO BE SOLVED: To provide a cooling system, capable of continuously circulating cooling liquid even during repairing a pump. SOLUTION: Repair valves 20a, 20c are provided for change-over between the case of circulating a heat medium into a heat collector 2a while bypassing pumps 10a, 10c and the case of circulating the heat medium into the heat collector 2a via the pumps 10a, 10c. As a result, the pumps 10a, 10c can be cut off a cooling main heat medium circuit by changing over a heat medium circuit using the repair valves 20a, 20c, and so the heat medium can be continuously circulated therein even during repairing the pump 10a or 10c and the reliability of the cooling system can be improved.
