Description

Technical Field

[0001] This utility model relates to the field of anti-interference devices, and in particular to a heat dissipation and anti-interference device for power line carrier communication. Background Technology

[0002] Power line carrier communication anti-interference device is a device installed on the outside of the power line to prevent interference in power line carrier communication. It mainly uses magnetic rings to isolate or filter out high-frequency noise pulse interference, enabling stable communication transmission over the power line. It is widely used in various power line applications.

[0003] In existing anti-interference devices, traditional magnetic rings are fixed to the cable surface by external clips or adhesive, leaving an air gap between the ring and the cable. This prevents efficient heat dissipation. When power lines operate under high load for extended periods, the cable temperature rises and is conducted to the magnetic ring. The permeability of ferrite and other magnetic core materials decreases exponentially with increasing temperature, creating a vicious cycle of thermal shielding failure. To alleviate the temperature rise problem, some solutions attempt to add heat sinks or fans to the outside of the magnetic ring. However, the heat dissipation module is installed separately from the shielding body, requiring openings to guide the heat medium or adding metal connectors, which creates new electromagnetic leakage paths and weakens the overall shielding effectiveness. As a result, the device cannot be used stably for a long time. Utility Model Content

[0004] The main objective of this invention is to provide a heat dissipation and anti-interference device for power line carrier communication, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A power line carrier communication heat dissipation and anti-interference device includes a protective shell, a connector, a threaded coupling ring, and a shielding magnetic ring. The connector is integrally formed at the upper and lower ends of the protective shell. The threaded coupling ring is threaded onto the outer side of the connector. The shielding magnetic ring is located inside the protective shell. A metal inner tube is fixedly installed on the inner wall of the protective shell. Multiple heat-conducting patches are attached to the inner wall of the metal inner tube. A heat transfer plate is integrally formed on the outer side of the metal inner tube. Two mounting brackets are fixedly installed on the outer side of the protective shell. A heat dissipation structure is provided on the outer side of the mounting brackets.

[0007] As a further embodiment of this utility model, the number of protective shells is two, and both protective shells are arranged in a semi-circular shape and symmetrically connected.

[0008] As a further embodiment of this utility model, the shielding magnetic ring is located inside the metal inner tube, and the heat transfer plate extends to the outside of the protective shell.

[0009] As a further embodiment of this utility model, the heat dissipation structure includes a heat dissipation mounting plate, mounting rings, heat dissipation fins, heat conduction pipes, and a heat conduction base. The heat dissipation mounting plate is located between two mounting brackets, and multiple mounting rings are respectively fixedly installed on both sides of the heat dissipation mounting plate. The heat dissipation fins and heat conduction pipes are both fixedly installed at the front end of the heat dissipation mounting plate, and the heat dissipation fins are located on the inner side of the heat conduction pipes and welded to them. The heat conduction base is fixedly installed at the bottom of the heat conduction pipes.

[0010] As a further embodiment of this utility model, the mounting collar is fitted around the outside of the mounting bracket, and the bottom of the heat-conducting pipe and the lower end of the heat-conducting base are fixedly connected to the upper end of the heat-conducting transfer plate.

[0011] As a further embodiment of this utility model, the bottom surface of the heat transfer plate is provided with two connecting screws, the ends of which pass upward through the heat transfer plate and are threadedly connected to the heat transfer base.

[0012] Compared with existing technologies, this utility model has the following advantages: By using a shielding magnetic ring built into the inside of a metal inner tube to directly wrap the power cable, it can effectively isolate or filter high-frequency noise pulse interference, significantly improve the stability of carrier communication signals, and, on the basis of anti-interference, the metal inner tube simultaneously serves as a heat-conducting skeleton and a carrier for fixing the magnetic ring. Heat is discharged through an integrally formed heat-conducting transfer plate and then cooled by heat dissipation fins. While preventing interference with the power line, heat dissipation and cooling are achieved at the same time, which also avoids the performance degradation of the shielding magnetic ring caused by high temperature. At the same time, the tight installation of the shielding magnetic ring ensures that the shielding effectiveness is not affected by the heat dissipation structure. The anti-interference and heat dissipation are deeply integrated in the structure, which not only ensures the long-term stability of communication anti-interference performance, but also extends the equipment life through active heat dissipation, making it particularly suitable for high-load power line carrier communication scenarios.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a heat dissipation and anti-interference device for power line carrier communication is described. Please refer to it carefully. Figures 1-4 The protective housing includes a protective shell 1, a connecting pipe 2, a threaded connecting ring 3, and a shielding magnetic ring 5. The connecting pipe 2 is integrally formed at the upper and lower ends of the protective shell 1. The threaded connecting ring 3 is threaded on the outside of the connecting pipe 2. The shielding magnetic ring 5 is located inside the protective shell 1. A metal inner tube 4 is fixedly installed on the inner wall of the protective shell 1. Multiple heat-conducting patches 6 are pasted on the inner wall of the metal inner tube 4. A heat transfer plate 7 is integrally formed on the outside of the metal inner tube 4. Two mounting brackets 8 are fixedly installed on the outside of the protective shell 1. A heat dissipation structure 9 is provided on the outside of the mounting brackets 8.

[0020] Please refer to this carefully. Figure 1 There are two protective shells 1, and both protective shells 1 are semi-circular and symmetrically connected.

[0021] Please refer to this carefully. Figures 2-4 The shielding magnetic ring 5 is located inside the metal inner tube 4, and the heat transfer plate 7 extends to the outside of the protective shell 1.

[0022] Specifically, the two protective shells 1 form the main structure that wraps around the outside of the power line. The two protective shells 1 are installed and fixed on the outside of the connector 2 by threaded coupling rings 3. At the same time, the metal inner tube 4 is attached to the outside of the power line, which also makes the shielding magnetic ring 5 wrap around the outside of the power line. By utilizing the material properties of the magnet, the high-frequency noise pulse interference is isolated or filtered out, so as to achieve anti-interference use for the carrier communication of the power line.

[0023] Please refer to this carefully. Figures 2-4The heat dissipation structure 9 includes a heat dissipation mounting plate 10, mounting rings 11, heat dissipation fins 12, heat conduction pipes 13, and heat conduction base 14. The heat dissipation mounting plate 10 is located between two mounting brackets 8. Multiple mounting rings 11 are fixedly installed on both sides of the heat dissipation mounting plate 10. The heat dissipation fins 12 and heat conduction pipes 13 are both fixedly installed at the front end of the heat dissipation mounting plate 10. The heat dissipation fins 12 are located inside the heat conduction pipes 13 and are welded and fixed thereto. The heat conduction base 14 is fixedly installed at the bottom of the heat conduction pipes 13.

[0024] Please refer to this carefully. Figures 2-4 The mounting collar 11 is fitted onto the outside of the mounting bracket 8, and the bottom of the heat conduction pipe 13 and the lower end of the heat conduction base 14 are fixedly connected to the upper end of the heat conduction plate 7.

[0025] Specifically, the heat dissipation mounting plate 10 is quickly installed on the mounting bracket 8 via the mounting collar 11. When the metal inner tube 4 is attached to the power line, the heat of the power line is transferred to the metal inner tube 4 through the heat-conducting patch 6. The metal inner tube 4 then transfers the heat to the heat-conducting transfer plate 7. The heat-conducting transfer plate 7 is attached to the heat-conducting pipe 13, thereby allowing the heat-conducting pipe 13 to transfer the heat to the heat dissipation fins 12. The heat dissipation fins 12 increase the contact area with the air, thereby achieving heat dissipation and simultaneously dissipating heat from the interference-proof power line.

[0026] Please refer to this carefully. Figures 2-4 The bottom surface of the heat transfer plate 7 is provided with two connecting screws 15. The ends of the connecting screws 15 pass upward through the heat transfer plate 7 and are threadedly connected to the heat transfer base 14.

[0027] Specifically, the heat transfer plate 7 is securely connected to the heat transfer base 14 by the connecting screw 15, so as to stably transfer the heat of the heat transfer plate 7 to the heat transfer pipe 13.
