ABSTRACT:
In a magnetic disk drive unit, air is pumped by the magnetic disks through a closed recirculating air path extending over and under the base plate. The air is pumped through a heat exchanger and an air filter to maintain uniform temperature and cleanliness of the recirculating air. A blower driven from the motor which drives the hub pumps air through the ambient side of the heat exchanger to effect a heat transfer from the enclosure.
