Patent ID: 6927980

Claim:
A cooling structure for a disk storage device accommodating at least one disk drive, comprising: the disk storage device having a connection board to which the disk drive is electrically connected such that data input/output to/from the disk drive is performed via a signal line formed on the connection board; a heat-absorbing part provided on the disk drive; a heat-dissipating part exposed outside the disk storage device; and a heat-transferring part for connecting the heat-absorbing part and the heat-dissipating part, wherein heat generated by the disk drive is transmitted from the heat-absorbing part via the heat-transferring part to the heat-dissipating part to radiate the heat, whereby an opening for air cooling is substantially eliminated from the connection board, and wherein the heat-transferring part separably includes a heat-absorbing-side heat-transferring part coupled to the heat-absorbing part and provided at the disk drive side, and a heat-dissipating-side heat-transferring part coupled to the heat-dissipating part and provided at the connection board side, tooth portions of the heat-absorbing-side heat-transferring part and tooth portions of the heat-dissipating-side heat-transferring part fit together to provide surface contact.
