Enhancement of Hard Disk Drive Heat Dissipations With Integrated Cooling Devices

Thermal management has become a significant issue to be considered whilst designing high performance and high reliable hard disk drives (HDD). This paper proposes a compact ultra-thin cooling device for enhancing heat dissipation of HDD. The miniature device was designed and prototyped to its optimal cooling efficiency according to the thermal characteristics of operating HDD. The experimental results of this newly developed device show that it can offer up to 35% enhancement of heat dissipation with a lower power consumption of 10 mW. Furthermore, the low power consumption device has been fully integrated with the disk drive without modifying the structure of the disk drive. This device provides a key for the design engineers in developing reliable and longer operational life hard disk drives.
