PROBLEM TO BE SOLVED: To sufficiently cool a second heat generation body when heat generation amount of a first heat generation body is reduced while suppressing increase in manufacturing cost of a cooling system. SOLUTION: Heat medium cooled by outside air in an outdoor heat exchanger 8 is circulated in an auxiliary cooling device 17 to assist cooling of the second heat generation body 3 when performing normal operation. When an abnormality occurs in a refrigerator 4, valves 14b, 14d are operated, and heat medium heated in a first heat collection device 2a is directly led into the outdoor heat exchanger 8 through a bypass circuit 16 to cool the first heat generation body 2. Consequently, even if heat generation amount of the first heat generation body 2 is reduced and refrigeration capacity generated in the refrigerator 4 is reduced, it is possible to cool the second heat generation body 3 without providing a new cooling means and exposing the second heat generation body 3 to outside air containing much dust directly.
