Description

Technical Field

[0001] This utility model relates to the field of server rack technology, and in particular to a silent server rack. Background Technology

[0002] A server rack is a freestanding structure used for installing and maintaining electrical or electronic equipment. It is usually made of cold-rolled steel or alloy materials and has functions such as dustproof, waterproof and electromagnetic interference protection. A silent server rack is a special type of server rack that uses noise reduction technology to reduce the noise generated by electrical or electronic equipment and transmitted to the outside through the rack.

[0003] The existing silent server racks have poor sound insulation, especially the doors and sides. This is because the doors are mostly single-layer panels, and although sound-insulating material is installed on the inner walls, its effectiveness is limited. The sides of the racks have cooling fans installed, and ventilation holes must be created to support these fans. Sound-insulating material cannot be installed in these areas, resulting in poor overall sound insulation. Furthermore, installing electrical or electronic equipment inside existing silent server racks requires multiple people, making installation and adjustment inconvenient, time-consuming, and labor-intensive, thus requiring further improvement.

[0044] Working principle:

[0045] When both silent front cabinet doors 2 and both silent rear cabinet doors 3 are closed, each cooling fan 35 in the two silent rear cabinet doors 3 is activated. Each cooling fan 35 draws the heat inside the silent cabinet 1 into the rear door box 32 through the window 341, and then into the U-shaped rear door cover 31 through the gap formed between the upper edge of the partition 33 and the upper or lower edge of the opening of the rear door box 32. Since the cover 36 closes the upper opening of the U-shaped rear door cover 31, the hot air inside the U-shaped rear door cover 31 is discharged outward through the lower opening of the U-shaped rear door cover 31. The outside air first enters the interior of the front door outer cover 21 through each air inlet slot 211, then enters the interior of the front door inner cover 25 through each first ventilation hole 231 and a corresponding second ventilation hole 241, and finally enters the interior of the silent cabinet 1 through the air inlet 251, thus forming a circulating airflow trajectory.

[0046] The equipment located inside the silent cabinet 1 is fixed inside the silent cabinet 1 by two mounting brackets, and the fixed position of the U-shaped longitudinal beam 18 in each mounting bracket can be adjusted back and forth along the length direction of the two U-shaped crossbeams 19 as needed. During adjustment, first unscrew the four screws 111 on each U-shaped longitudinal beam 18, and then slide the U-shaped longitudinal beam 18 back and forth with the cooperation of the fastener 184 and the U-shaped flange groove 191. Thus, the position of the U-shaped longitudinal beam 18 can be quickly and safely adjusted while ensuring that the U-shaped longitudinal beam 18 is always connected to the U-shaped crossbeam 19, without removing the U-shaped longitudinal beam 18. This can be completed by only one operator.

[0047] This invention relocates the cooling fans originally located on the side of the cabinet to the two silent rear cabinet doors 3, allowing the sound insulation material to fully cover the sides of the cabinet, effectively improving sound insulation. Simultaneously, the two silent front cabinet doors 2 and the two silent rear cabinet doors 3 employ a multi-layered structure, ensuring both adequate airflow for heat dissipation and effective sound insulation, further enhancing sound insulation. Furthermore, this invention allows for convenient installation and adjustment of electrical or electronic equipment by a single person using the two mounting brackets, achieving time and labor savings.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
