Abstract
In order to provide a rotating machine in which the temperature increase distribution inside the machine can be equalized, not only is a primary cooler installed in the primary ventilation passage that extends from the exhaust side of the fans and installed on the rotating axis to the suction side of the fans and via the core, but a secondary cooler is installed in the secondary ventilation passage that is branched from the primary ventilation passage, thus making it possible to further cool part of the cooling medium, which has once been cooled by the primary cooler, by means of the secondary cooler, that is, to cool the cooling medium by circulating it through the coolers twice.
