PURPOSE:To make effective cooling, by circulating the air in the device through a heat exchanger, in a magnetic device of an tightly enclosed construction. CONSTITUTION:The air in a disc device warmed with the generated heat due to the rotation of a disc 2 is delivered to a heat exchanger 6 through a duct 5 with an air flowing outlet 8 provided in the vicinity of the external circumference of the disc of an enclosure 1 accompanied with the disc. On the other hand, the external air is drawn in with a fan 7 located aside the heat exchanger and led into the heat exchanger 6. The air in the device taking its heat and cooled with the external air is returned in the disc enclosure from an air flowing inlet 9. Thus, the temperature rise in the disc device is suppressed to a prescribed temperature and the value is depending on the performance of the heat exchanger 6. |
