PROBLEM TO BE SOLVED: To provide a cooling system whose coolant is not oxidized for long-term use and keeps its low electrical conductivity in the presence of peroxides by employing an ion exchange resin excellent in oxidation resistant property.SOLUTION: A cooling system of the invention comprises a coolant, coolant circulating means for circulating the coolant, and an ion exchange resin introduced into the coolant circulating means. The ion exchange resin is ion-exchanged with one or more ions selected from the group consisting of an alkyl ammonium ion, a phosphonium ion, a cerium ion, and a manganese ion. Into the coolant circulating means, one or more insoluble compounds selected from the group consisting of a bismuth compound, a zirconium compound, a manganese compound, and a rare earth compound may be further introduced. |
