Abstract
A cooling device cools down a wheel having a disc shape. The wheel is hermetically enclosed in an enclosure and rotationally driven about a rotation shaft. The cooling device includes blade members that are disposed on one surface of the wheel, a heat dissipater to which a gas heated by the wheel is blown by the blade members due to rotation of the wheel, and a gas flow definer that is located inside the enclosure, and separates a flow path along which the gas that has been cooled by the heat dissipater flows before being blown to the one surface and a flow path along which the gas that has been blown to the one surface and heated flows.
