DETAILED DESCRIPTION OF THE INVENTION

[0011] The following provides a detailed technical content of the present invention along with the accompanied drawings. However, the accompanied drawings are provided for reference and illustrative purpose only such that they shall not be used to limit the scope of the present invention.

[0012] Please refer to FIG. 1, FIG. 2 and FIG. 3, showing a perspective view of a hard drive rack with ventilation structure of the present invention, perspective exploded view and perspective assembly view of primary rack and secondary racks respectively. The present invention provides a hard drive rack ventilation structure, and the hard drive rack is applicable to a server requiring the use of plurality of hard drives stacked in layers with a relatively compact configuration. The hard drive rack ventilation structure comprises a primary rack, a plurality of secondary racks 11 and 12 and a plurality of hard drive units 2.

[0013] Accordingly, the primary rack 1 can be formed by a sheet metal through stamping and bending processes, and it is used for integrating the aforementioned secondary racks 11 and 12. Therefore, the configuration of the primary rack 1 is not limited to the ones shown in the accompanied drawings of the present invention. It mainly comprises two frame walls 10 arranged spaced apart from each other in order to use the separation distance between the two frame walls 10 to allow each one of the secondary racks 11 and 12 to be installed therein.

[0014] The plurality of secondary racks 11 and 12 can also be formed by a sheet metal through stamping and bending processes and are assembled between the two frame walls 10 of the aforementioned primary rack 1 in order to facilitate the installation of required quantity of hard drives. To be more specific, each one of the secondary racks 11 and 12 includes a top portion 110/120. In addition, side portions 111/121 extend downward from the two sides of the top portion 110/120 respectively, and sliding tracks 112/122 are correspondingly arranged on the two side portions 111/121. It can be understood that the secondary racks 11 and 12 can be stacked in layers depending upon the actual quantity demand of the hard drives in order to use known fixation methods, such as fastening screws or other assembly methods, to assembly the secondary racks 11 and 12 between the two frame walls 10 of the primary rack 1.

[0015] The plurality of hard drive units 2 can be installed inside each one of the aforementioned secondary racks 11 and 12. Each one of the hard drive units 2 comprises a hard drive main body 20 and a handle 21 installed at a front end of the hard drive main body 20. In addition, the hard drive main body 20 can be horizontally inserted into the sliding tracks 112/122 provided at the internal of the two side portions 111/121 of each one of the secondary racks 11 and 12. The handle 21 is exposed outside of the secondary rack 11, such that during the removal of the hard drive main body 20, the handle 21 can be pulled in order to remove the corresponding hard drive main 20 out of the secondary rack 11 or 12.

[0016] As shown in FIG. 4. in an exemplary embodiment of the present invention, a gap 210 is formed between the hard drive main body 20 and the handle 21 of each hard drive unit 2, and the front edge of the top portion 110 and 120 of each secondary rack 11 and 12 includes a hollow portion 110a and 120a formed corresponding to the gap 210 of each hard drive unit 2. The hollow portion 110a and 120a can be a notch recessed inward at the front edge of the top portion 110 and 120, or it can also be a cut-out portion (not shown in the drawings) formed adjacent to the front edge of the top portion 110 and 120. Furthermore, the hollow portion 110a and 120a is fluidly and vertically connected to the gap 210 of each hard drive unit 2 in order to form an airflow ventilation channel P.

[0017] Consequently, with the aforementioned structural assembly, the hard drive rack ventilation structure of the present invention can be achieved.

[0018] Accordingly, as shown in FIG. 4, when the secondary racks 11 and 12 are installed to carry a plurality of hard drive units 2 at full capacity and during the operation of the server, the external air is able to be drawn in or out from the front end of the primary rack 1. Since the airflow may not be uniform, the gaps among the hard drive units 2 cannot maintain a smooth airflow therethrough. To overcome such drawback, with the airflow ventilation channel P provided in the present invention and fluidly connected to the gaps 210 among hard drive units 2, the external air is able to enter from the top most or the bottom most hard drive unit 2, or to allow the hot air at the internal to be exhaust out with ease. As a result, all of the hard drive units 2 installed at different layers can obtain a preferable head dissipation effect through the design of the airflow ventilation channel P, and the issue of machine shutdown due to high temperature caused by the accumulation of heat generated by the hard drive units 2 installed at the middle layers of the rack can be overcome.

[0019] Furthermore, as shown in FIG. 1, in a preferred exemplary embodiment of the present invention, in terms of the scope of the vertical projection of the hollow portions 110a and 120a in a top-down or bottom-up manner, the scope of the hollow portions is able to cover the scope of the gaps 210 in order to facilitate the air to enter from the external space more easily.

[0020] In view of the above, the present invention is able to achieve the objectives of the present invention and to overcome the drawbacks of known arts. The present invention is novel and of inventive step, which satisfies the patentability requirements.

[0021] The above describes the preferable and feasible exemplary embodiments of the present invention for illustrative purposes only, which shall not be treated as limitations of the scope of the present invention. Any equivalent changes and modifications made in accordance with the scope of the claims of the present invention shall be considered to be within the scope of the claim of the present invention.
