The air-cooled heat dissipation server is equipped with a certain number of fans to dissipate heat for the internal logic unit, computing unit, control unit, storage unit, and other modules of the system. The fan speed of the server is as high as 10,000RPM+, and the high-speed rotating fan is particularly noisy; the fan grid is very large, and the large mesh is proportional to the weight. The fan supports hot-swappable actions. The larger the grid, the greater the safety hazard for maintenance personnel. In the man-machine environment, it is often necessary to wear noise-cancelling headphones or earplugs; professionals frequently operate servers or maintain online, such as: updating firmware, plugging and unplugging fans, plugging and unplugging SAS/SATA/Power cables, etc. Because the grid size is much larger than fingers, there are potential safety hazards, and the high-speed rotating fan blades are extremely easy to cause mechanical damage and cut fingers.

Based on this, in order to prevent the risk of mechanical damage and reduce the noise of the human-machine environment, a safe and intelligent server fan design device and control system are designed to improve the heat dissipation environment and make it more secure and intelligent.

In one embodiment, as shown in FIG. 1 , a method for controlling a server fan safety barrier is provided, the method comprising:

Step 102, after the server is powered on, the server fan keeps running according to the default value of the baseboard management controller, wherein a safety fence is provided at the air outlet of the fan, and the safety fence is controlled by the safety fence signal to realize closing or opening;

Step 104, identifying the state of the case cover through the sensor, and judging whether the current state of the case cover is open or closed;

Step 106, if the sensor recognizes that the state of the chassis cover is closed, then interrupt the failure of the controller, and normally drive the safety barrier signal of the fan to keep the safety barrier of the fan open;

Step 108, if the sensor recognizes that the state of the case cover is open, an interrupt controller is triggered, and the interrupt controller interrupts the safety fence signal of the fan to close the safety fence.

In this embodiment, a method for controlling the safety fence of a server fan is provided, which can be applied in the fields of servers, computers, switches, etc., by improving the design of the fan structure, taking into account the effect of heat dissipation and noise reduction to achieve more security and Intelligent design concept. The design shall be such that it is impossible for a skilled technician to inadvertently touch the tip of the high-speed rotating fan blade due to involuntary withdrawal when servicing a Class 2 or Class 3 energy source. The design should prevent fingers from touching the tip of the fan blade in the risk area, and technicians can freely hot-swap the server fan without any mechanical damage. The fan safety fence is closed, which can achieve the effect of noise reduction. Through the opening of the fence design not larger than 5mm, the heat dissipation of the system can still be maintained, and the man-machine interface is friendly when no noise-cancelling headphones or earplugs are worn.

Specifically, referring to the schematic flowchart of the control method shown in FIG. 2 , first, after the server is powered on, the fan of the server keeps running according to the default value of the baseboard management controller. A baseboard management controller (BMC) is a dedicated service processor that uses sensors to monitor the status of a computer, network server, or other hardware-driven device, and communicates with the system administrator through an independent connection line. communication. The BMC's sensors measure internal physical variables and if any of these variables fall outside established limits, it notifies the administrator.

Wherein, a safety fence is provided at the air outlet of the fan, and the safety fence is controlled by a signal of the safety fence to realize closing or opening. The state of the chassis cover is recognized by the sensor, and it is judged whether the current state of the chassis cover is open or closed. If the sensor recognizes that the state of the case cover is closed, the interrupt controller fails, and the safety fence signal of the fan is normally driven to keep the safety fence of the fan open. If the sensor recognizes that the state of the case cover is open, an interruption controller is triggered, and the safety fence signal of the fan is interrupted by the interruption controller to close the safety fence.

Specifically, its control principle is shown in Figure 3: After the server is powered on, the fan starts to run according to the default value of the BMC. When the sensor recognizes that the chassis cover is open, the Intruder controller intervenes to interrupt the fan control safety fence signal, and the fan safety fence The gate is closed; when the sensor recognizes that the chassis cover is closed, the Intruder controller fails, the fan normally drives the safety barrier signal, and the safety barrier remains open.

In this embodiment, the state of the chassis cover is identified by the sensor, and it is judged whether the current state of the chassis cover is open or closed; if the sensor identifies the state of the chassis cover as closed, the interrupt controller fails, and the safety barrier signal of the fan is normally driven to enable the fan to operate. The safety fence remains open; if the sensor recognizes that the chassis cover is open, an interrupt controller is triggered, and the safety fence signal of the fan is interrupted by the interrupt controller to close the safety fence. This solution can prevent the fingers in the risk area from touching the tip of the fan blade, and technicians can freely hot-swap the server fan without any risk of mechanical damage. The noise reduction effect can be achieved by closing the fan safety fence, and there is no need to wear noise reduction headphones or earplugs. In addition, the design of vents through the grille can still keep the system from dissipating heat, ensuring safety while ensuring that the system will not overheat.

In one embodiment, an outer frame is provided at the air outlet of the fan, and a group of safety fence blades arranged horizontally are arranged on the outer frame, and the safety fence blades are controlled by the safety fence signal to rotate around the rotating shaft to realize opening. or off.

In one embodiment, an outer frame is provided at the air outlet of the fan, and a group of safety fence blades arranged longitudinally are arranged on the outer frame, and the safety fence blades are controlled by the safety fence signal to rotate around the rotating shaft to realize opening. or off.

Specifically, referring to Fig. 4-Fig. 7, by improving the design of the fan structure: in the open or closed state of the horizontal or vertical safety fence, the design of the safety fence leaves is not more than 5mm openings, and the spacing between the ventilation holes is not more than 10mm. Through the above design scheme, it can not only ensure safety but also reduce noise, and still maintain good heat dissipation.

By improving the design of the fan structure, taking into account the heat dissipation and noise reduction effects to achieve a safer and more intelligent design concept. The design shall be such that it is impossible for a skilled technician to inadvertently touch the tip of the high-speed rotating fan blade due to involuntary withdrawal when servicing a Class 2 or Class 3 energy source. It can prevent the fingers in the risk area from touching the tip of the fan blade, and technicians can freely hot-swap the server fan without any mechanical damage.
