1. A cooling device for sub-MRI units, the cooling device comprising:
a tank in which cooling water for cooling a heat generating unit that an MRI apparatus has is stored;
a pump which circulates the cooling water stored in the tank through a circulation path starting from the tank and traveling around the heat generating unit;
a heat exchanger which cools the cooling water; and
a controller which decides that a water leakage has occurred on the circulation path when a decreasing rate of the cooling water in the tank is greater than a given reference value.
