[0001] The utility model relates to the technical field of heat dissipation of switches, in particular to a heat dissipation device for switches. Background Art

[0002] A switch is a network device used for forwarding electrical signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common switches include telephone voice switches and fiber optic switches. As the integration of switches increases and their performance improves, the heat generated during operation also increases. An efficient heat dissipation system is essential to ensure the stable operation and extend the service life of these devices.

[0003] In addition, different models and sizes of switches may require different cooling solutions, which requires the cooling system to be not only efficient but also highly scalable and flexible to adapt to various structures. Utility Model Content

[0004] The purpose of the utility model is to provide a heat dissipation device for a switch to solve the problem that the heat dissipation system should not only be highly efficient but also have high scalability and flexibility.

[0005] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a switch heat dissipation device, including two heat dissipation pipes, both of which are arranged inside the switch shell, and the outer wall of the heat dissipation pipe is provided with a plurality of aluminum rods, and the bottom end of the aluminum rod is fixed with a thermal conductive gasket, and the inside of the heat dissipation pipe is fixed with a thermal conductive silicone sheet, and the bottom end of the aluminum rod extends to the inside of the heat dissipation pipe and fits with the outer wall of the thermal conductive silicone sheet. Magnetic levitation fans are fixed inside both ends of the heat dissipation pipe, one end of the heat dissipation pipe is provided with a threaded ring groove, and the other end of the heat dissipation pipe is fixed with a threaded ring tube, the two heat dissipation pipes are threadedly connected together with the threaded ring tube through the threaded ring groove, and the connection between the two heat dissipation pipes can be replaced with a pipe in the shape of the letter "L".

[0006] Preferably, the outer wall of the heat dissipation pipe is provided with a plurality of threaded holes, the outer wall of the aluminum rod is provided with screw threads, and the aluminum rod is threadedly connected to the outer wall of the heat dissipation pipe through the screw threads and the threaded holes.

[0007] Preferably, fixing holes are respectively opened on the left and right sides of the switch housing, first rubber rings are respectively fixed to the two ends of the two heat dissipation pipes that are away from each other, and a fixing ring is fixed to the outer wall of the first rubber ring, and the fixing ring is fixed to the inside of the fixing hole.

[0010] Preferably, a temperature sensor is fixed on one side of the magnetic levitation fan, a PLC controller is fixed on the outside of the switch housing, and the magnetic levitation fan and the temperature sensor are both electrically connected to the PLC controller.

[0011] Compared with the prior art, a switch heat dissipation device using the above technical solution has the following beneficial effects:

[0012] 1. During use, the connection between the threaded ring groove and the threaded ring tube allows more heat dissipation pipes to be added to adapt to switch housings of different sizes and models. This makes the heat dissipation system highly flexible and adaptable. The "L"-shaped pipe is used so that the direction of the heat dissipation pipe can be changed according to actual needs, thereby avoiding interference with other equipment inside the switch housing during installation. By adjusting the direction of the "L"-shaped pipe and adapting it with the threaded ring groove and the threaded ring tube, it can better adapt to the internal structure of the switch housing with different structures, ensuring the compatibility and efficient operation of the heat dissipation system; using the excellent thermal conductivity of the aluminum rod, the heat inside the switch housing can be quickly transferred to the thermal pad. Combined with the active heat dissipation of the magnetic levitation fan, efficient temperature control and heat discharge are achieved. Through the use of the temperature sensor and the PLC controller, the temperature changes inside the heat dissipation pipe can be monitored in real time, and the magnetic levitation fan can be automatically started for heat dissipation, ensuring precise temperature control. The two magnetic levitation fans rotate in the same direction to create a more uniform airflow, which helps to evenly distribute and effectively remove the heat inside the heat dissipation pipe.

[0013] 2. The staff can support the hanging rod on the bottom surface of the switch shell to ensure the overall stability of the heat dissipation pipe. If there is equipment on the inner bottom surface of the heat dissipation pipe, the hanging rod can be rotated, and the staff can fix the hanging rod and the fixing plate to the side or top surface of the switch shell through the bolt mounting holes, thereby improving the installation flexibility of the device.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, a heat dissipation device for a switch comprises two heat dissipation pipes 1, both of which are arranged inside a switch housing 2, a plurality of aluminum rods 3 are arranged on the outer wall of the heat dissipation pipe 1, a heat conductive pad 4 is fixed to the bottom end of the aluminum rod 3, a heat conductive silicone sheet 5 is fixed inside the heat dissipation pipe 1, the bottom end of the aluminum rod 3 extends to the inside of the heat dissipation pipe 1 and fits the outer wall of the heat conductive silicone sheet 5, a magnetic levitation fan 6 is fixed inside both ends of the heat dissipation pipe 1, a temperature sensor is fixed on one side of the magnetic levitation fan 6, a PLC controller is fixed on the outside of the switch housing 2, the magnetic levitation fan 6 and the temperature sensor are electrically connected to the PLC controller, a plurality of threaded holes 7 are opened on the outer wall of the heat dissipation pipe 1, a screw thread 8 is opened on the outer wall of the aluminum rod 3, and the aluminum rod 3 is threadedly connected to the outer wall of the heat dissipation pipe 1 through the screw thread 8 and the threaded hole 7.

[0022] During use, when the temperature inside the switch housing 2 rises, the aluminum material of the aluminum rod 3 can better transfer heat to the thermally conductive gasket 4, and the contact between the thermally conductive gasket 4 and the magnetic levitation fan 6 can transfer heat to the surface of the magnetic levitation fan 6. When the temperature inside the heat dissipation pipe 1 rises, the temperature sensor transmits a signal to the PLC controller, and the PLC controller transmits a start signal to the magnetic levitation fan 6. At this time, the two magnetic levitation fans 6 inside the heat dissipation pipe 1 rotate in the same direction. Through the rotation of the two magnetic levitation fans 6, the temperature inside the pipe is removed, and then the heat generated inside the heat dissipation pipe 1 is removed to achieve the effect of heat dissipation. The staff twists the aluminum rod 3, and the threaded connection between the threaded hole 7 and the screw thread 8 drives the bottom end of the aluminum rod 3 to better fix the thermally conductive gasket 4 on the surface of the thermally conductive silicone sheet 5, ensuring that the contact between the thermally conductive gasket 4 and the thermally conductive silicone sheet 5 is more sufficient, thereby improving the thermal conductivity efficiency.

[0023] By utilizing the excellent thermal conductivity of the aluminum rod 3, the heat inside the switch housing 2 can be quickly transferred to the thermal pad 4. Combined with the active heat dissipation of the magnetic suspension fan 6, efficient temperature control and heat discharge are achieved. Through the coordinated use of the temperature sensor and the PLC controller, the temperature changes inside the heat dissipation pipe 1 can be monitored in real time, and the magnetic suspension fan 6 can be automatically started for heat dissipation, ensuring accurate temperature control. The two magnetic suspension fans 6 rotate in the same direction to create a more uniform airflow, which helps to evenly distribute and effectively remove the heat inside the heat dissipation pipe 1.

[0024] like Figure 1-Figure 5 As shown, a threaded ring groove 9 is formed at one end of the heat dissipation pipe 1 , a threaded ring tube 10 is fixed at the other end of the heat dissipation pipe 1 , and two heat dissipation pipes 1 are threadedly connected together through the threaded ring groove 9 and the threaded ring tube 10 .

[0025] During use, through the threaded connection between the threaded ring groove 9 and the threaded ring tube 10, more heat dissipation pipes 1 can be added to adapt to switch casings 2 of different sizes and models. At the same time, a pipe in the shape of the letter "L" can be set. The two ends of the pipe in the shape of the letter "L" need to be adapted and used with the threaded ring groove 9 and the threaded ring tube 10 respectively, so that the path direction of the heat dissipation pipe 1 can be changed, so that the heat dissipation system has high flexibility and adaptability. By using the pipe in the shape of the letter "L", the direction of the heat dissipation pipe 1 can be changed according to actual needs, thereby avoiding interference with other equipment inside the switch casing 2 during installation. By adjusting the direction of the "L"-shaped pipe and adapting it with the threaded ring groove 9 and the threaded ring tube 10, it can better adapt to the internal structure of the switch casing 2 of different structures, ensuring the compatibility and efficient operation of the heat dissipation system.

[0026] like Figure 2-Figure 4As shown, fixing holes 11 are respectively provided on the left and right sides of the switch housing 2, and first rubber rings 13 are respectively fixed to the two ends of the two heat dissipation pipes 1 that are away from each other, and a fixing ring 12 is fixed to the outer wall of the first rubber ring 13, and the fixing ring 12 is fixed to the inside of the fixing hole 11. A second rubber ring 16 is sleeved at the connection between the two heat dissipation pipes 1, and a hanging ring 14 is fixed to the outer wall of the second rubber ring 16, and a hanging rod 15 is fixed to the outer wall of the hanging ring 14, and the bottom end of the hanging rod 15 extends to the inner bottom surface of the switch housing 2, and a fixing plate 17 is fixed to the bottom end of the hanging rod 15, and a plurality of bolt mounting holes 18 are provided on the top surface of the fixing plate 17.

[0027] In use, when the magnetic levitation fan 6 is working, the first rubber ring 13 and the second rubber ring 16 can better reduce the vibration generated by the magnetic levitation fan 6 when it is working, and effectively reduce the noise. At the same time, the staff can support the suspension rod 15 on the bottom surface of the switch housing 2 to ensure the overall stability of the heat dissipation pipe 1. If there is equipment on the inner bottom surface of the heat dissipation pipe 1, the suspension rod 15 can be rotated, and the staff can fix the suspension rod 15 and the fixing plate 17 to the side or top surface of the switch housing 2 through the bolt mounting hole 18, thereby improving the installation flexibility of the device (at the same time, the length of the suspension rod 15 can also be set according to actual conditions).

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
