Abstract
Provided is a cooling system that has a reduced risk of contaminating the circulation path of the insulating coolant composition with water. The cooling system includes an insulating coolant composition, a circulation path through which the coolant composition circulates, an inlet through which the circulation path communicates with an external space, and a fluorine-based resin filter covering the inlet. The rate at which the coolant composition at 25° C. passes through the filter is greater than 1 mL·s. The rate at which water at 25° C. passes through the filter is less than or equal to 8×10mL·s.
