[0043] like Figure 1-9 As shown, an embodiment of the present invention provides a high-efficiency heat dissipation fan for intelligent communication network equipment, comprising a mounting plate 1 mounted on the intelligent communication network equipment, a fan assembly 2 for heat dissipation, and a plurality of sensor assemblies for detecting temperature. A mounting hole 4 is defined in the middle of the mounting plate 1. A fixing cylinder 6 is rotatably connected to the interior of the mounting hole 4 via a rotating assembly 5. An air guide 8 is rotatably connected to the interior of the fixing cylinder 6 via an air guide adjustment assembly 7. The fan assembly 2 is mounted within the air guide 8, and the sensor assembly is fixed to the lower surface of the mounting plate 1.

[0044] The fan assembly 2 includes a mounting bracket 9 fixedly connected to the inside of the air guide tube 8, and a stepless speed regulation motor 10 is fixedly connected to the upper surface of the mounting bracket 9. The output end of the stepless speed regulation motor 10 is fixedly connected to a rotating shaft 11, and the other end of the rotating shaft 11 is fixedly connected to a mounting cap 13 through a screw 12. The outer surface of the mounting cap 13 is rotatably connected to multiple circular shafts 14 through bearings, and one end of the circular shaft 14 is fixedly connected to a fan blade 15. A fan blade adjustment assembly is provided inside the mounting cap 13, and the fan blade adjustment assembly is used to adjust the angle of the fan blade 15.

[0045] like Figure 1 and Figure 5 As shown, in this embodiment, the sensor assembly includes a first sensor 16, a second sensor 17, a third sensor 18 and a fourth sensor 19. Four mounting grooves are opened at the four corners of the lower surface of the mounting plate 1. The first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 are respectively installed in the four mounting grooves. The first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 are all flush with the lower surface of the mounting plate 1. The first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 are all connected to the external controller through wires.

[0046] When the first sensor 16 detects that the temperature threshold is greater than the temperature of the second sensor 17, the third sensor 18 and the fourth sensor 19, it sends a signal to the external controller, which controls the air guide tube 8 to rotate to the first sensor 16;

[0047] When the second sensor 17 detects that the temperature threshold is greater than the temperature of the first sensor 16, the third sensor 18 and the fourth sensor 19, it sends a signal to the external controller, which controls the air guide tube 8 to rotate to the second sensor 17;

[0048] When the third sensor 18 detects that the temperature threshold is greater than the temperature of the first sensor 16, the second sensor 17 and the fourth sensor 19, it sends a signal to the external controller, which controls the air guide tube 8 to rotate to the third sensor 18;

[0049] When the fourth sensor 19 detects that the temperature threshold is greater than the temperature of the first sensor 16, the second sensor 17 and the third sensor 18, it sends a signal to the external controller, which controls the air guide tube 8 to rotate to the fourth sensor 19;

[0050] When the first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 detect that the temperature is greater than the warning temperature threshold, a signal is sent to the external main control, and the external controller controls the fan assembly 2 to increase to full speed.

[0051] Since the heating elements inside the intelligent communication network equipment are not evenly distributed, the internal heat distribution is also uneven, which directly leads to different temperatures detected by the first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19. When the temperatures detected by multiple sensors are compared through an external controller, for example, the temperature detected by the first sensor 16 is significantly higher than that of the other three sensors, when it exceeds 15 degrees, the external controller controls the rotation of the air duct 8. When it is detected that the temperature is greater than the warning temperature threshold, for example, greater than 50 degrees, the fan assembly 2 is controlled by the external controller to increase to full speed.

[0052] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the rotating assembly 5 includes a first motor 501 fixedly connected to the upper surface of the mounting plate 1, the output end of the first motor 501 is fixedly connected to the first gear 502, the outer surface of the fixed cylinder 6 is fixedly connected to the ring gear 503, the first gear 502 is meshed with the ring gear 503, and the fixed cylinder 6 is rotatably connected to the inside of the mounting hole 4 through a bearing.

[0053] In this way, the external controller starts the first motor 501 and can drive the first gear 502 to rotate. During the rotation, the first gear 502 engages with the ring gear 503 and can drive the fixed tube 6, the air guide tube 8 and the fan assembly 2 to rotate.

[0054] like Figure 5 and Figure 7 As shown, in this embodiment, the air duct adjustment assembly 7 includes a fixed box 701 fixedly connected to the front side of the fixed cylinder 6, the inner wall of the fixed box 701 is fixedly connected to the second motor 702, the output end of the second motor 702 is fixedly connected to the worm 703, and the front and rear sides of the air guide cylinder 8 are respectively fixedly connected to the first round rod 704 and the second round rod 705, the first round rod 704 and the second round rod 705 are both rotatably connected to the fixed cylinder 6 through bearings, the other end of the first round rod 704 is located inside the fixed box 701 and is fixedly connected to the worm gear 706, and the worm gear 706 is meshed with the worm gear 703.

[0055] In this way, after the external controller starts the second motor 702, it can drive the worm 703 to rotate. During the rotation process, the worm 703 cooperates with the worm wheel 706 to drive the air guide tube 8 and the fan assembly 2 to rotate around the first round rod 704, causing the air outlet of the air guide tube 8 to tilt.

[0056] like Figure 1 and Figure 2 As shown, in this embodiment, the mounting plate 1 is made of a high thermal conductivity metal material and has through holes 101 at all four corners. A plurality of heat dissipation fins 102 are fixedly connected to the outer side of the mounting plate 1 , and the mounting plate 1 and the heat dissipation fins 102 are integrally formed.

[0057] In this way, when the fan blades 15 rotate at high speed, a strong airflow will be formed to take away the heat inside the intelligent communication network device. At the same time, when the surface temperature of the intelligent communication network device is high, the mounting plate 1 can dissipate excess heat and quickly diffuse the heat into the air through the heat dissipation fins 102 on the outside of the mounting plate 1, thereby improving the heat dissipation effect.

[0058] like Figure 1 and Figure 8 As shown, in this embodiment, the mounting frame 9 includes a fixing plate 901, and a plurality of support rods 902 are fixedly connected to the outer surface of the fixing plate 901, and the other end of the support rod 902 is fixedly connected to the inner wall of the air guide tube 8, so that the gaps between the plurality of support rods 902 can be ventilated, thereby better fixing the stepless speed regulation motor 10.

[0059] like Figure 5 、 Figure 6 and Figure 9 As shown, in this embodiment, the fan blade adjustment assembly includes an electromagnetic armature 20 slidably connected to the inside of the mounting cap 13, the lower surface of the rotating shaft 11 is stepped and is sleeved with an electromagnetic core 21, the bottom end of the rotating shaft 11 is threadedly connected to a nut 22, a spring 23 is arranged between the nut 22 and the electromagnetic armature 20, the upper surface of the electromagnetic armature 20 is fixedly connected to a plurality of racks 24, one end of the circular shaft 14 located inside the mounting cap 13 is fixedly connected to a second gear 25, the rack 24 is meshed with the second gear 25, and the electromagnetic core 21 is used to attract the electromagnetic armature 20 after being energized, the left and right sides of the electromagnetic armature 20 are fixedly connected with sliders 26, and the left and right inner walls of the mounting cap 13 are provided with sliding grooves 27 corresponding to the sliders 26.

[0060] The technical solution provided by the present invention is to fix the mounting plate 1 on the intelligent communication network device through the mounting hole 4, so that the temperature detection component is fitted with the intelligent communication network device, and the temperature distribution of the intelligent communication network device is detected in real time. Since the heating elements inside the intelligent communication network device are not evenly distributed, the internal heat distribution is also uneven, which directly leads to different temperatures detected by the first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19. When the temperatures detected by multiple sensors are compared through an external controller, for example, the temperature detected by the first sensor 16 is significantly higher than that of the other three sensors, when it exceeds 15 degrees, the external controller starts the second motor 702 to drive the worm 703 to rotate. During the rotation, the worm 703 cooperates with the worm gear 706 to drive the air guide tube 8 and the fan assembly 2 to rotate around the first round rod 704, causing the air outlet of the air guide tube 8 to tilt. Then, after starting the first motor 501, the first gear 502 can be driven to rotate. During the rotation, the first gear 502 During the process, the engagement with the gear ring 503 can drive the fixed cylinder 6, the air guide cylinder 8 and the fan assembly 2 to rotate until the air outlet of the air guide cylinder 8 is toward the side of the first sensor 16. At this time, the airflow generated by the fan blades 15 will take away more high-temperature heat from the first sensor 16. When the first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 detect that the temperature is greater than the warning temperature threshold, a signal is sent to the external main control, and the fan assembly 2 is controlled by the external controller to increase to full speed. When the air volume demand is large, the external controller energizes the electromagnet core 21 to generate suction. At this time, the electromagnetic armature 20 is attracted to the electromagnet core 21 and compresses the spring 23. At the same time, the electromagnetic armature 20 is attracted and can drive the rack 24 to move. During the movement, the rack 24 cooperates with the second gear 25 to drive the circular shaft 14 and the fan blades 15 to rotate. The exhaust volume of the cooling fan is accurately adjusted by controlling the voltage of the electromagnet core 21, so that the air volume adjustment requirements of the cooling fan can be met by changing the angle of the fan blades 15.

[0061] In addition, to solve the above technical problems, the present invention also provides a method for manufacturing a high-efficiency heat dissipation fan for intelligent communication network equipment, the manufacturing method comprising the following steps:

[0062] S1. When in use, the electromagnet core 21 is sleeved on the rotating shaft 11, and then the nut 22 is tightened to fix the electromagnet core 21 to the rotating shaft 11. Then, the spring 23 is sleeved and the mounting cap 13 is fixed to the rotating shaft 11 by the screw 12. At this time, the electromagnet core 21 can be attracted to the electromagnetic armature 20 after being energized, forming a fan assembly 2 that can adjust the angle of the fan blades 15;

[0063] S2. Fix the fan assembly 2 inside the air guide tube 8. Since the air guide tube 8 can rotate around the first round rod 704 and the second round rod 705, the fixing tube 6 is then rotatably installed in the mounting hole 4 through the bearing to form a high-efficiency heat dissipation fan.

[0064] S3. Fix the mounting plate 1 to the intelligent communication network device through the mounting hole 4 so that the temperature detection component fits the intelligent communication network device and detects the temperature distribution of the intelligent communication network device in real time;

[0065] S4. Electrically connect the temperature detection component, the rotating component 5, the air duct adjustment component 7 and the stepless speed regulation motor 10 to the external controller, and detect the temperature through the first sensor 16, the second sensor 17, the third sensor 18 and the fourth sensor 19 so that the external controller can control the rotation component 5, the air duct adjustment component 7 and the stepless speed regulation motor 10 to achieve efficient heat dissipation.

To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0068] The above is only a preferred embodiment of the present invention.
