摘要 |
A radiation apparatus of a hard disk drive includes a base frame, a spindle motor installed at the base frame, a hard disk rotatably supported by a rotation shaft of the spindle motor, a cover frame coupled to the base frame and having a hole formed therein, a radiation plate installed at the cover frame and formed of a copper alloy having a thermal conductivity higher than that of the cover frame, and a portion for coupling the rotation shaft and the radiation plate so that driving heat generated by the spindle motor can be directly transferred to the radiation plate.
