Description

Technical Field

[0001] The present invention relates to the field of data servers, and specifically to a data server maintained by multiple power supplies. Background Art

[0002] A data server is responsible for storing data, managing data access permissions, providing data query and update services, and ensuring the security and integrity of data. It usually runs a database management system and can efficiently process a large amount of data, supporting complex queries and transaction management. In addition, the data server also has the ability of high availability and quick recovery to ensure that the service can be quickly restored in case of a failure.

[0003] Since a single power failure will cause the server to shut down, in order to ensure the high availability and reliability of the server and avoid service interruption or data loss caused by power failure, multiple power supplies are added to continuously power the server, reducing the failure rate and extending the overall life of the server. Among them, the air-cooling system is a conventional cooling method for the server, which cools down through fans and computer room air conditioners. The air conditioners are all located outside the cabinet where the server is installed. However, the temperature inside the cabinet is relatively high. Moreover, the servers are generally installed in a stacked manner, and it is difficult to cool the servers near the middle position of the cabinet well, and the situation of uneven heat dissipation is likely to occur.

A cavity for the rocker 15 to be limited and slide is opened inside the positioning support plate 13. The middle position of the rocker 15 is rotatably installed in the cavity of the positioning support plate 13 through a shaft rod 27. When the end of the rocker 15 away from the connecting rod 14 swings downward, the heat insulation sleeve 11 can be pulled to move through the connecting rod 14. A pressure rod 16 is provided at the end of the rocker 15 away from the connecting rod 14. Long strip grooves for the pressure rod 16 and the connecting rod 14 to be limited and slide are opened at both ends of the rocker 15, enabling the rocker 15 to pull the pressure rod 16 and the connecting rod 14 to move through the long strip grooves. A pressure roller 17 is fixedly installed on the outer side of the pressure rod 16. A chute for the pressure rod 16 and the pressure roller 17 to be limited and slide is opened on the outer side of the positioning support plate 13.

[0033] Embodiment 3: Please refer to Figure 3 , Figure 7 and Figure 8 . This embodiment further illustrates other embodiments. The anti-blocking mechanism in the figure includes an exhaust cylinder 20 fixedly installed at one end of the exhaust pipe 7 away from the air guide pipe 5. The end of the exhaust cylinder 20 close to the exhaust pipe 7 is a hollow frustum structure, which increases the size of the exhaust cylinder 20 to facilitate rapid exhaust and discharge the hot air from the exhaust pipe 7. A positioning bracket 21 is fixedly installed inside the exhaust cylinder 20. A rotating rod 22 is rotatably installed inside the positioning bracket 21. A fan 23 is fixedly installed at one end of the rotating rod 22 close to the exhaust pipe 7. When the hot air enters the exhaust cylinder 20, it can drive the fan 23 to rotate, and the fan 23 drives the rotating rod 22 to rotate. Two symmetrically distributed positioning shafts 30 are fixedly installed on the outer side of the rotating rod 22. The outer side of the positioning shaft 30 is in contact with the outer side of the positioning bracket 21 to improve the stability of the rotation of the rotating rod 22. A filter screen 32 is fixedly installed on one side of the positioning bracket 21 away from the fan 23, which can block the dust outside the exhaust cylinder 20 and prevent fine dust from entering the exhaust pipe 7 through the exhaust cylinder 20 when the air box 6 stops operating. One end of the rotating rod 22 away from the fan 23 extends to the outside of the filter screen 32. A plurality of centrally symmetrically distributed support rods 24 are fixedly installed at one end of the rotating rod 22 away from the fan 23, so that the rotating rod 22 can drive the support rods 24 to rotate synchronously. A spiral scraping strip 25 is fixedly installed at one end of the support rod 24 away from the rotating rod 22. The outer side of the spiral scraping strip 25 is in contact with the inner side of the exhaust cylinder 20. When the support rod 24 rotates, it can drive the spiral scraping strip 25 to move in a circular motion along the inner side of the exhaust cylinder 20, and use the spiral scraping strip 25 to discharge the dust and particulate impurities inside the exhaust cylinder 20 to achieve the effect of exhaust anti-blocking. A scraper 26 is fixedly installed on one side of the support rod 24 close to the filter screen 32. The outer side of the scraper 26 is in contact with the outer side of the filter screen 32, which can scrape off the fine dust adhered to the filter screen 32 and discharge it from the exhaust cylinder 20 along with the hot air. A plurality of equally spaced guide inclined plates 31 are fixedly installed inside the exhaust cylinder 20 to prevent large particle impurities from entering the exhaust cylinder 20.

[0034] Working principle: First, the staff member opens the cabinet body 1, and sequentially installs multiple server bodies 2 between the corresponding two positioning support plates 13. The server body 2 moves along the outer side of the positioning support plate 13, so that the bottom of the server body 2 comes into contact with the outer side of the pressure roller 17. The bottom of the server body 2 presses the pressure roller 17 to move downward, causing the pressure roller 17 and the pressure rod 16 to move downward along the chute on the positioning support plate 13. The pressure rod 16 drives the seesaw 15 to swing with the shaft rod 27 as the fulcrum. The other end of the seesaw 15 drives the connecting rod 14 to move upward, causing the connecting rod 14 to drive the heat insulation sleeve 11 to move along the groove of the positioning support plate 13. The heat insulation sleeve 11 drives the heat conduction sleeve seat 9 to move upward along the outer side of the air duct 5 or the branch pipe 8, causing the heat conduction strip 10 to move into the insertion hole of the air duct 5 or the branch pipe 8. At the same time, the heat conduction sleeve seat 9 drives the heat conduction fin 12 to come into contact with the bottom of the server body 2, so that the heat conduction fin 12 is closely attached to the bottom of the server body 2. Subsequently, the staff member docks the server body 2 with the power connection board 4, enabling multiple power supplies in the power supply box 3 to supply power to the server body 2, realizing multi-power maintenance of the server body 2 and ensuring the normal power supply of the server body 2. Then, the staff member starts the air box 6. The air box 6 inhales the cold air outside the cabinet body 1 and sends it into the two air ducts 5. The air ducts 5 disperse the cold air into the two branch pipes 8. At this time, the heat generated by the operation of the server body 2 can be conducted into the heat conduction fin 12. The heat conduction fin 12 sends the heat into the heat conduction sleeve seat 9. The heat conduction strip 10 inside the heat conduction sleeve seat 9 conducts the heat into the air duct 5 or the branch pipe 8, enabling the cold air in the air duct 5 and the branch pipe 8 to push the heat upward, realizing uniform heat dissipation for multiple server bodies 2 and ensuring the normal operation of the server body 2. Finally, the heat in the branch pipe 8 returns to the air duct 5 along with the air flow. The air duct 5 concentrates the heat and sends it into the exhaust pipe 7. The exhaust pipe 7 sends the heated air flow into the exhaust cylinder 20, causing the air flow to drive the fan 23 to rotate. The fan 23 drives the rotating rod 22 to rotate. The rotating rod 22 drives multiple support rods 24 to rotate synchronously. The support rods 24 drive the spiral scraping strip 25 to move in a circular motion along the inner side of the exhaust cylinder 20, pushing the dust and particulate impurities on the inner side of the exhaust cylinder 20 out from the end of the exhaust cylinder 20, achieving the effect of cleaning and preventing blockage of the exhaust cylinder 20 and ensuring the normal discharge of heat, thereby achieving the effect of uniform heat dissipation and ensuring the normal operation of the server body 2.
