Problems solved by technology
In particular, conventional compact hard disk drives have a disadvantage: the vertical circulation of air within the enclosure is almost impossible
In this case, if the uniform circulation of air cannot be achieved in the housing, the air under the pan cannot easily flow to the upper part of the pan, and the dust particles contained in the airflow under the pan are difficult to be filtered
Therefore, there is a problem here, the spindle motor, disk and actuator are easily contaminated by dust particles, which can adversely affect their performance
[0010] Also, due to the heat conducted from the printed circuit board mounted on the bottom surface of the disk substrate to stay on the underside of the disk, the reliability of the hard disk drive may be adversely affected by local temperature rise

A hard disk drive with an air circulation unit. The hard disk drive includes a housing having a base and a cover, a spindle motor installed on the base, a disk mounted on the spindle motor to store data, an actuator pivotally installed on the base and having a read / write head to write data on the disk or to reproduce the data from the disk, and an air circulation unit installed in the housing to circulate air vertically in the housing by moving air flow produced by rotation of the disk vertically. The air circulation unit may be arranged around the disk so that the air circulation unit is positioned adjacent to an edge of the disk. In particular, the air circulation unit may be installed at a position opposite to the actuator with respect to a center of the disk. The air circulation unit includes at least one of an air ascending member to move air from a lower portion of the disk upward to an upper portion of the disk and an air descending member to move air from the upper portion of the disk downward to the lower portion of the disk. The air below or above the disk is easily moved toward the upper portion or lower portion of the disk by the air circulation unit.
Description
[0001] This application claims priority from Korean Patent Application No. 2005-57650 filed with the Korean Intellectual Property Office on June 30, 2005, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a hard disk drive, and more particularly, the present invention relates to a hard disk drive having an air circulation device for uniformly circulating air in the hard disk drive. Background technique [0003] A hard disk drive (HDD) is an information storage device used in a personal computer that uses a read / write head to reproduce data from (ie read from) or write data to a disk. [0004] A conventional hard disk drive includes a housing having a base and a cover, a spindle motor mounted on the base, at least one disk mounted on the spindle motor for storing data thereon, and an actuator for actuating the read / write head Moving to the desired location on the disc, the head reproduces data from or...
