Embodiments of Disclosure

Referring to FIGS. 1 to 11, the present embodiment provides a server 10, which includes a chassis structure 20 provided with a plurality of slots 29 and a plurality of hard disks 11 inserted in the slots 29 (the slots 29 can be seen in FIG. 11).

Referring to FIGS. 2 and 6, the chassis structure 20 includes a chassis body 21, two fan components 22, two tray components 23, and a power supply 24. Referring to FIG. 9, the chassis body 21 has a receiving space 25. Two partitions 26 are arranged in the chassis body at intervals. The two partitions 26 divide the receiving space 25 into a middle cavity 27 in between the two partitions 26 and two side cavities 28 outside the two partitions 26. The fan component 22 is connected to the chassis body 21, and each fan component 22 is arranged at an end of the two side cavities 28. Referring to FIG. 11, each of the two tray components 23 defines a plurality of slots 29 for inserting hard disk 11. The two tray components 23 are installed in the side cavities 28. The power supply 24 is arranged in the middle cavity 27 and supplies power to the hard disks 11 inserted in the slot 29. The power supply 24 has a fan 30, and the power supply 24 is positioned at one end of the middle cavity 27.

In the chassis structure 20 in this embodiment, the partition 26 separates the receiving space 25 of the chassis body 21, and the power supply 24 being set in the middle cavity 27 and the tray components 23 being set in the side cavities 28 on each side. The fan component on both sides and the power supply in the middle form three parallel air ducts in the two side cavities and the middle cavity, which reduces the air flow loss and greatly improves the heat dissipation efficiency. At the same time, the tray components 23 on both sides are separated by the middle cavity 27, avoiding excessive density of the lateral hard disks 11.

In the embodiment, optionally, the chassis body 21 includes a top wall and an opposite bottom wall, two side walls face each other. The four walls together form the enclosure with openings at the front and rear. The fan component 22 and the power supply 24 are arranged at the rear openings. There is a fan component 22 arranged on both sides and the power supply 24 is arranged in the middle. The tray component 23 can be pulled out from the front opening. When the tray component 23 is not extended, part of its structure is located at the front opening of the enclosure wall, but there are holes to avoid the front opening being sealed, allowing the side cavities 28 and the middle cavity 27 to form air ducts through the front and rear openings of the enclosure.

In this embodiment, the partition 26 is parallel to the side wall 33. The space between the two partitions 26 is relatively small, so as to define the middle cavity 27, which accommodates narrow structures such as power supply 24. The spacing between the partition 26 and side walls 33 is set relatively large, so as to be about three times the spacing between the two partitions 26, this allows the tray component 23 to be set larger, so as to accommodate more hard disks 11.

Alternatively, each tray component 23 is slidably arranged in the side cavity 28 through a sliding component 34. The sliding component 34 comprises a bracket 35 and two sliding rails 36. Each of the slide rails 36 is connected to one of side wall 33 and one of the two partitions 26 and are opposite to each other. The bracket 35 comprises a bottom plate 37 and two side plates 38 connected to both sides of the bottom plate 37. The two side plates 38 are connected to the two slide rails 36, so that the bracket 35 is slidably connected to the chassis body 21. The tray component 23 is connected to the bracket 35. The sliding component 34 allows the easy extraction of the tray component 23, for hard disk extraction, insertion, maintenance, and replacement. FIG. 10 shows a hard disk 11 extracted. Alternatively, the power supply cable, signal cable, and other cables of the tray component 23 can be connected to the chassis body 21 through the trailing chain 40, so that cables can be moved while still connected.

Alternatively, the tray component 23 is rotatably connected to the bracket 35 through a hinge 41. The hinge 41 comprises a first plate 42 and a second plate 43 rotatably connected to the first plate 42. The second plate 43 is attached to the bottom of an inner side surface of one of the side plates 38, and a bottom surface of the tray component 23 is attached and fixedly connected to the first plate 42, so that the side of the tray component 23 away from the hinge 41 can rotate to a position higher than the side plate 38 on that side. This would expose the slot 29 opened on that side of the tray component 23, so as to facilitate the insertion and removal of the hard disk 11. FIG. 11 shows the tray component 23 extracted and rotated. Alternatively, the bottom plate 37 is slidably supported on the bottom wall 32 to share the load of the tray component 23 on the slide rail 36. When the tray component 23 carries more hard disks 11, this arrangement avoids an excessive loading from bending the slide rails 36.

In this embodiment, both ends of each tray component 23 are respectively retracted from the two ends corresponding to one of the two side cavities 28, to define an end air duct 44 between the two end faces of the tray component 23 and the outer end of the side cavity 28. The ends of the tray components 23 are fitted with a lifting handle 45. One end of the lifting handle 45 is rotatably connected to the tray component 23, and the other end of the lifting handle 45 can be rotated to be contained in an end air duct 44 or out of the end air duct 44, which is used to rotate the tray component 23 relative to the bracket 35 by lifting the lifting handle 45. The lifting handle 45 can be stored in the space of the end air duct 44, it being smaller in size than the end air duct 44 to avoid blocking the air flow of the end air duct 44. One end of the lifting handle 45 can be lifted to realize rotation of the tray component 23. Alternatively, both sides of the tray component 23 are separated from the side wall 33 and partition 26 to define a side air duct 46. Alternatively, the spacing between the two side plates 38 is greater than the lateral dimension of the tray component 23, and both sides of the tray component 23 are separated from the side plates 38. In this way, heat dissipation of the tray component 23 is less influenced by the side plate 38.

Alternatively, the slide rail 36 is arranged on the side close to the bottom plate 37, and its vertical dimension is less than the spacing between the top wall 31 and the bottom wall 32. The vertical dimension of the side plate 38 approximately matches the vertical dimension of the slide rail 36. Thus, the slide rail 36 and the side plate 38 near the top wall 31 are not blocked, and the lateral width of the side air duct 46 is approximately the same distance as that between the side of the tray component 23 and the side wall 33. Near the bottom wall 32, the lateral width of the side air duct 46 is approximately the same as the distance from the side of the tray component 23 to the side plate 38. Overall, such side air duct 46 can achieve better heat dissipation while also permitting the installation of various structural parts.

In this embodiment, the sliding component 34 further comprises a front plate 47 connected to the bracket 35. The front plate 47 define a plurality of air inlets 48. The air inlet 48 and the fan component 22 communicate through the side air duct 46 to form a heat dissipating air duct. The outside of the front plate 47 is fitted with a handle 49 for pulling and a hook 50 for clamping. When the tray component 23 and the sliding component 34 are retracted inside, the hook 50 clamps to the chassis body 21. To pull out the tray component 23, the hook 50 is unlocked, and then the handle 49 is lifted.

In this embodiment, a front outgoing line structure 51 and a rear outgoing line structure 52 are at the ends of the middle cavity 27 for the front and rear outlet of the tray component 23. The rear outgoing line structure 52 and the power supply 24 are arranged side by side. The front outgoing line structure 51 has a front air hole 53, which is connected to the fan 30 through the middle cavity 27. Alternatively, the front outgoing line structure 51 includes a front interface frame 54 and a plurality of front interface pieces 55 installed on the front interface frame 54. A front exposed hole 56 and a front air hole 53 are on the front interface frame 54. The front interface piece 55 is exposed from the front exposed hole 56. The rear outgoing line structure 52 includes a rear interface frame 58 and a plurality of rear interface pieces 59 installed on the rear interface frame 58. A rear exposed hole 60 is arranged on the rear interface frame 58. The rear interface piece 59 is exposed from the rear exposed hole 60. By these means, the chassis structure 20 in this embodiment can conveniently realize front and rear outgoing lines at the same time.

In this embodiment, the partition 26 is provided with an air vent 61, which is located between the front outgoing line structure 51 and the rear outgoing line structure 52. The air vent 61 connects with the middle cavity 27 and the side cavity 28 on each side to balance the air pressure of the middle cavity 27 and each side cavity 28. The air vent 61 includes holes longitudinally arranged along the partition 26, and each hole is in a section of the partition 26 away from the fan component 22. In this embodiment, by opening the air vent 61 at the section of the partition 26 away from the fan component 22, the problem of a small and insufficient air inlet area when the outgoing line structure is set at the front and rear of the chassis structure 20 can be compensated, so that the air entering from the front plate 47 can partially flow into the middle cavity 27 at the air inlet section. That is, not only is there a sufficient air inlet for the middle cavity 27 and the two side cavities 28, for heat dissipation, but the relative independence of the air ducts of the three cavities is maintained to a certain extent, especially in the section where the air vent 61 is close to the fan component 22 to further enhance the heat dissipation.

The present embodiment further provides a method of dissipating heat from server, which includes:

Starting the fan component 22 and the fan 30 to form a heat dissipating air duct in the middle cavity 27 and the side cavity 28 when the server is used, so as to cool the server 10.

Although the application is described in detail with reference to the above preferred embodiments, those skilled in the art should understand that any modification or equivalent replacement of the technical solution of the application should not deviate from the spirit and scope of the technical solution of the application.
