This design allows the arc-shaped guide vane 2 to be quickly disassembled and maintained when needed. The cross section of the clamping groove 4.2 is trapezoidal, and the clamping block 4.3 can be clamped with the clamping groove 4.2. The clamping groove 4.2 is fixedly connected to one side of the inner wall, and the cross section of the clamping block 4.3 is trapezoidal and is arranged at the bottom end of the first rotating rod 4.5 close to one side of the clamping groove 4.2.

This process is simple and fast, which greatly reduces the maintenance time and labor intensity.

[0026] As Figure 2As shown, the top end of the axial rod 3 is designed to be fixedly installed with the reversing assembly 5, which is designed to realize the rapid adjustment and optimization of the airflow direction. The shell of the reversing assembly 5 is composed of a second fixed cover 5.1, which not only provides structural protection but also serves as a support structure for the rotating components. The top end of the axial rod 3 is connected to a second rotating rod 5.2, and the top end of the second rotating rod 5.2 is designed to rotate within the second fixed cover 5.1, allowing the axial rod 3 to rotate freely within the fixed cover and thus adjusting the direction of the guide vane. The inner wall of the top end of the second fixed cover 5.1 is provided with a second groove to accommodate the top end of the second rotating rod 5.2 and allow it to rotate freely within the groove. The bottom end of the second rotating rod 5.2 is connected to the axial rod 3 through a hexagonal bolt 5.8, which not only provides stability but also facilitates disassembly and maintenance. The bottom end of the second rotating rod 5.2 is provided with a square groove 5.2.1, and the side walls of the square groove 5.2.1 are provided with holes. The top end of the axial rod 3 is provided with holes that align with the holes in the top end of the axial rod 3. The hexagonal bolt 5.8 passes through the square groove 5.2.1 and the holes in the top end of the axial rod 3 to fix them. The top end of the axial rod 3 is installed in the square groove 5.2.1 of the second rotating rod 5.2 through the hexagonal bolt 5.8. The connection between the axial rod 3 and the second rotating rod 5.2 is more stable, providing the possibility of quick disassembly and maintenance, and increasing the convenience of maintenance. This design allows the second rotating rod 5.2 to drive the axial rod 3 to rotate freely within the second fixed cover 5.1, and the bolt connection provides the possibility of quick disassembly and maintenance, increasing the convenience of maintenance. When the arc-shaped guide vane 2 needs to be removed, the operator only needs to disconnect the hexagonal bolt 5.8 between the second rotating rod 5.2 and the axial rod 3, then push the pushing piece 4.4 to the left, compress the spring 4.6, and make the clamping block 4.3 disengage from the clamping groove 4.2, so that the arc-shaped guide vane 2 can be easily removed with assistance. This quick disassembly design makes the maintenance and cleaning of the arc-shaped guide vane 2 more convenient and efficient. The second rotating rod 5.2 is provided with a first bevel gear 5.4, which is engaged with a second bevel gear 5.5. This design allows the angle of the arc-shaped guide vane 2 to be adjusted to adapt to different airflow optimization requirements. The first bevel gear 5.4 and the second bevel gear 5.5 are arranged vertically, which ensures the stability and accuracy of the transmission. The second bevel gear 5.5 is connected to a gear shaft 5.6, which is fixed to the lower surface of the second fixed cover 5.1 mounting seat through a bearing 5.3. The gear shaft 5.6 is horizontally arranged, and the right end is fixedly connected with a handle 5.7, which facilitates the manual adjustment of the position of the bevel gear by the operator to adapt to different airflow optimization requirements. This manual adjustment method, although simple, is very effective and can quickly respond to the adjustment requirements of the airflow direction. If the airflow direction needs to be changed, the operator only needs to twist the handle 5.7 to make the second bevel gear 5.5 rotate, thereby driving the first bevel gear 5.4 to rotate, and further driving the axial rod 3 to rotate, and finally driving the arc-shaped guide vane 2 to rotate, achieving the change of the wind direction.The transmission mechanism is not only fast in response, but also simple in operation, so that the whole air flow optimization process is more efficient and accurate.

[0027] The first fixed cover 4.1 and the second fixed cover 5.1 are open rectangular shells, and the open ends of the first fixed cover 4.1 and the second fixed cover 5.1 are provided with a plurality of mounting seats, preferably four mounting seats in this embodiment, which are arranged on the four edges of the open face of the second fixed cover 5.1, and the mounting seats are fixedly installed on the air conditioner air deflector 1. A plurality of mounting holes are provided on the mounting seat, and preferably four mounting holes are provided on each mounting seat in this embodiment, which are installed on the air conditioner air deflector 1 through the mounting holes. The design of the mounting seat makes the connection of the fixed cover and the air conditioner air deflector 1 more stable, provides multiple fixing points, and enhances the stability and wind resistance of the whole device.

[0028] The central axis of the arc-shaped guide vane 2 coincides with the axial rod 3, the inner end close to the axial rod 3 is arc-shaped, the outer end is straight, and a plurality of arc-shaped guide vanes 2 are uniformly distributed in the horizontal direction. The height of the arc-shaped guide vane 2 is greater than or equal to 500 mm and less than or equal to the height of the air conditioner air deflector 1, the width of the guide vane is 200 mm, and the thickness is 1.2 mm. The spacing of the guide vanes is 1 / 7 of the width of the air conditioner, and they are uniformly distributed in the horizontal direction. The air flow with a deflection angle of the sinking fan first enters the inner end of the arc-shaped guide vane 2, and the shape of the arc-shaped guide vane 2 gradually transitions from arc-shaped to straight to change the direction of the air flow. The design of the arc-shaped guide vane 2 optimizes the distribution of the air flow, making the air flow more evenly distributed in the air outlet, reducing the formation of air flow dead angle and vortex, and improving the energy efficiency and comfort of the air conditioner. The uniformly distributed guide vanes in the horizontal direction further ensure the uniformity of the air flow and improve the overall air flow optimization effect.

[0029] In this embodiment, the data center air flow organization of two cases of air conditioner without static pressure tank air flow optimization device and air conditioner with static pressure tank air flow optimization device is simulated.

[0030] Air conditioner without static pressure tank air flow optimization device: after the fan sinks, the air conditioner air supply with a deflection angle deviates to one side in the static pressure tank. As shown in the simulation results of the air flow field and temperature field of the data center without using the air flow optimization device, the air flow of the air conditioner deviates to one side, and a large air flow vortex appears on the other side, which will reduce the air intake of the cabinet in that area. The temperature of the air inlet and outlet of the cabinet in the air flow vortex position is high, which is not conducive to the safe operation of the server in the cabinet. It is necessary to correct the direction of the air outlet of the air conditioner.

[0031] The air conditioner uses static pressure tank air flow optimization device: after the arc guide vane 2 is installed in the air conditioner air deflector 1, the air conditioner air outlet has no deflection angle. The data room flow field and temperature field simulation results show that after the air conditioner air outlet has no deflection angle, only the air flow vortex near the standby air conditioner is relatively obvious, the air conditioner air supply is uniformly distributed in the cold aisle, and the temperature in the original cabinet inlet and outlet area and other areas is almost consistent. Therefore, the air conditioner air outlet direction is corrected, which can effectively solve the problem of uneven air supply in the cold aisle and reduce the temperature of the hot area.

[0032] Through the installation and adjustment of the above-mentioned device, the gas turbulence with the air outlet inclination angle is effectively controlled and reconstructed. The air flow is blown into the computer room in the positive direction, and the air flow in the cold aisle is uniformly distributed. Such uniform air flow helps to avoid the generation of hot areas and hot spots, improves the efficiency of the air conditioning system, and reduces energy waste.

[0033] Obviously, the above embodiments are only examples for the purpose of clarity, and are not limitations on the embodiments. Based on the above description, those skilled in the art can make other different forms of changes or variations. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes and variations derived therefrom are still within the protection scope of the present application.
