1. A cooling device for cooling a constituent element housed in a housing of a unit subjected to an influence of a generated magnetic field, the cooling device comprising:
a water cooling mechanism configured to cool the constituent element by cooling a cooling plate with a flow of water flowing through a pipe passing through the cooling plate arranged in the housing; and
at least one air cooling mechanism arranged on an outgoing side where the flow of water flowing through the pipe is outgoing from the housing and configured to cool the constituent element by discharging air in the housing along with the water flow in accordance with the water flow,
wherein the air cooling mechanism suctions the air in the housing using a pressure difference between a pressure of the air in the housing and a pressure which decreases with a flow rate increased by making a flow channel of the water flow thinner.
