[0002] Computer servers generate heat when running, so a cooling fan is installed on the server chassis to dissipate heat and ensure stable operation of the server in the chassis.

[0003] When the existing server chassis is running, the fan blade shaft and the bearing ring are prone to lack of lubricating oil after long-term operation, which increases the friction between the fan blade and the bearing ring and generates noise. Secondly, the existing chassis lacks a dust blowing structure, which causes the fan blades to absorb dust due to static electricity after long-term operation. When the fan blades are attached with dust, noise will also be generated during operation. Utility Model Content

[0022] like Figure 1-4 As shown, lubricating oil can be stored in the oil storage bottle 7, and the oil injection peristaltic pump 6 provides power for the oil injection, so that the lubricating oil is sprayed into the inner side of the bearing ring 13, so that the fan blade 12 shaft and the bearing ring 13 are effectively lubricated, reducing the generation of noise, and the squeezing of the air bag 9 can send the gas to the soot blowing nozzle 16 through the blowing pipe 10 and the lifting pipe 17. The high-speed gas blown out of the soot blowing nozzle 16 can blow off the dust on both sides of the fan blade 12. At the same time, the rotating fan blade 12 can blow the blown dust out of the box 1, reducing the amount of dust attached to the fan blade 12, thereby reducing the noise generated when the fan blade 12 rotates.

[0023] A heat dissipation net 3 is arranged on the side of the fan blade 12 away from the bearing ring 13 , and a bottle cap 8 is arranged on the upper side of the oil storage bottle 7 .

[0024] like Figure 1-4 As shown, the bottle cap 8 can seal the top side of the oil storage bottle 7 to prevent contaminants from entering the oil storage bottle 7.

[0025] Side cover plates 2 are arranged on the two outer side surfaces of the box body 1 , an air inlet net 4 is arranged at the lower part of the side cover plate 2 , and fixing screws 5 are arranged at the four corners of the side cover plate 2 .

[0026] like Figure 1-3 As shown, the side cover 2 is provided to facilitate installation of components required for the server inside the box 1 , and the fixing screws 5 can stably fix the side cover 2 on the box 1 .

[0027] A motor 15 is arranged on the side of the bearing ring 13 away from the fan blade 12. The motor 15 is connected to the fan blade 12 through the motor 15 shaft. The bearing ring 13 is plugged into the oil injection pipe 14. The bearing ring 13 can stably support the fan blade 12 shaft to ensure stable rotation of the fan blade 12.

[0030] The lower side of the bearing ring 13 is connected to the box body 1 by screws, and the sootblowing nozzle 16 is glued to the lifting pipe 17.

[0031] The working principle of a low-noise chassis for a computer server provided by the utility model is as follows: Figure 1-Figure 4 As shown, when in use, the server module installed inside the box 1 generates heat during operation, and the motor 15 drives the fan blades 12 to rotate quickly, thereby extracting and discharging the heat inside the box 1, so that the cold air outside the box 1 enters the box 1 through the air inlet net 4 to cool the server module. When the fan blades 12 run for a long time, the fan blades 12 will absorb dust due to static electricity. The lifting pipe 17 is moved up and down through the air blowing pipe 10, so that the dust blowing nozzle 16 is aligned with both sides of the fan blades 12 and moves up and down, and the air bag 9 is continuously pressed while moving. , so that high-speed gas is quickly blown out through the soot blowing nozzle 16, and then the soot is blown on both sides of the fan blade 12. The blown dust is blown out of the box body 1 under the action of the rotating fan blade 12, reducing the amount of dust attached to the fan blade 12, and thus reducing the noise generated when the fan blade 12 is running. By pressing the oil injection peristaltic pump 6, the lubricating oil in the oil storage bottle 7 can be extracted through the oil suction pipe 11, and sprayed into the bearing ring 13 through the oil injection pipe 14, so that the lubricating oil is added and lubricated between the inner side of the bearing ring 13 and the shaft of the fan blade 12, thereby reducing the noise caused by friction.
