ABSTRACT:
BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention herein relates to a hard disk drive heat dissipation device, wherein the body of the said device is installed onto the surface of a hard disk drive such that when the hard disk drive is operating, the fan positioned on the body directs cool air inward and the heated air generated is exhausted out through heat dissipation holes to achieve the objective of rapid cooling.
2) Description of the Prior Art
To support processors and software, the unit capacities of current hard disk drives have increased from megabytes to gigabytes and, furthermore, the read-write speeds have become faster and faster. Thus, how to rapidly exhaust the heated air generated by hard disk drives during operation and thereby prevent hard disk drive overheating and operating failure has become another major problem similar to the heat dissipation problems of processors. Since the conventional approach only consists of installing a fan at one end of the hard disk drive, when the fan rotates, the air flow from the exterior is blocked by the end of the hard disk drive, cannot be dispersed over the entire hard disk drive, and fails to reach the front end of the hard disk drive such that most of the heated air generated by the hard disk drive accumulates on the hard disk drive as a result of extremely limited heat dissipation performance.
SUMMARY OF THE INVENTION
To improve upon the various shortcomings of the said conventional device structure, the inventor of the invention herein conducted extensive research and testing which finally culminated in the successful design of the hard disk drive heat dissipation device of the invention herein.
The primary objective of the invention herein is to provide a hard disk drive heat dissipation device in which the body has a surface area of appropriate dimension, a fan is installed onto the body, and a number of heat dissipation holes are formed near the outer edges of the body such that when the body is secured against a hard disk drive, the rotating fan directs an air flow from the exterior onto the hard disk drive and, furthermore, the air flow is dispersed over the entire hard disk drive, and after the heated air generated by the hard disk drive is so driven, it is immediately exhausted out from the heat dissipation holes in the body to enable the rapid cooling of the hard disk drive.
Another objective of the invention herein is to provide a hard disk drive heat dissipation device in which an extension section is installed to each of the two sides of the body to enable users the option of directly mounting the assembled body and hard disk drive into a larger drive bay in a host machine.
Yet another objective of the invention herein is to provide a hard disk drive heat dissipation device in which one or more adjacent hook and tab are formed in the body along the side of the fan space so that the power wires of the fan can be tucked into the hook and situated against the tab and thereby neatly routed laterally next to the fan rather than being laid on the body in a disorderly state.
To enable a further understanding of the objectives, profile, structure, device innovations, and other functions of the invention herein, the brief description of the drawings below are followed by the detailed description of the preferred embodiments.
