Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a metal-clad electric heating cable with an optimized electrothermal structure, comprising: a pipe 1, connecting posts 2 are provided on both sides of the pipe 1 and the connecting posts 2 are fixedly connected to the pipe 1, a heating cable body 3 is uniformly wound on the surface of the connecting posts 2, the heating cable body 3 is arranged in a U-shape and distributed circumferentially, the heating cable body 3 includes a reinforcing sheath 14 and an outer sheath 8 is provided on the inner side of the reinforcing sheath 14, an inner insulation layer 9 is provided on the inner side of the outer sheath 8 and a PE reinforcing film 10 is provided inside the inner insulation layer 9, an electric heating component 11 is provided on the inner side of the PE reinforcing film 10 and two sets of busbar bodies 12 are provided inside the electric heating component 11, a heating wire 13 is provided between the two sets of busbar bodies 12, the heating wire 13 is arranged in a U-shape and flatly distributed on the surface of the electric heating component 11, connecting posts 2 are provided on both sides of the pipe 1 and the connecting posts 2 are fixedly connected to the pipe 1, and a heating cable body 3 is uniformly wound on the surface of the connecting posts 2. The heat tracing body 3 is U-shaped and circumferentially distributed, which increases the contact area between the heat tracing cable and the pipe 1 and improves the heat tracing effect. The heat tracing body 3 includes a reinforcing sheath 14 and an outer sheath 8 inside the reinforcing sheath 14. An inner insulation layer 9 is provided inside the outer sheath 8, and a PE reinforcing film 10 is provided inside the inner insulation layer 9. An electric heating element 11 is provided inside the PE reinforcing film 10, and two sets of busbar bodies 12 are provided inside the electric heating element 11. A heating wire 13 is provided between the two sets of busbar bodies 12, and the heating wire 13 is U-shaped and flatly distributed on the surface of the electric heating element 11. This configuration ensures the heating effect and allows heating only one side of the heat tracing cable, ensuring the heat tracing effect and avoiding heat waste. The U-shaped design has a large unfolded area and uniform heat distribution, which is suitable for scenarios that require rapid heating and stable temperature. By adjusting the density and length of the U-shaped structure, the power requirements can be precisely matched, resulting in significant energy-saving effects.

[0020] Further improvements, such as Figure 2 As shown: Both sides of the reinforcing sheath 14 are provided with reinforcing ribs 5 in a semi-arc structure. The design of the reinforcing ribs 5 enhances the mechanical strength of the reinforcing sheath 14, making it more resistant to the impact and compression of the external environment, protecting the safety of the internal electric heating component 11, and extending the service life of the electric heating tape.

[0021] Further improvements, such as Figure 2 As shown: The surface of the reinforcing sheath 14 is provided with an installation groove 6 and the interior of the installation groove 6 is provided with color-changing blocks 7. The color-changing blocks 7 are distributed at intervals and can change color with temperature changes, providing users with an intuitive temperature indication, facilitating monitoring of the working status of the electric heating tape, timely detection of problems and handling.

[0022] Further improvements, such as Figure 4 As shown: A metal braided mesh 15 is provided between the reinforcing sheath 14 and the inner insulation layer 9. The metal braided mesh 15 is made of interlaced metal wires. The metal braided mesh 15 enhances the tensile strength and wear resistance of the electric heating tape, while providing additional electromagnetic shielding effect and reducing the impact of external electromagnetic interference on the electric heating component 11.

[0023] Further improvements, such as Figure 4 As shown: The exposed end surface of the busbar body 12 is provided with busbar insulation 16. The busbar insulation 16 effectively isolates the busbar body 12 from the external environment, prevents electrical short circuits and leakage, and improves the safety performance of the electric heating tape.

[0024] Further improvements, such as Figure 1 As shown: The surface of the connecting column 2 is provided with a locking nut 4, and the locking nut 4 is threadedly connected to the connecting column 2 and pressed on the surface of the heat tracing cable body 3. The design of the locking nut 4 enables the heat tracing cable body 3 to be firmly fixed on the connecting column 2, preventing it from falling off due to vibration or external force during use, and ensuring the stable operation of the electric heat tracing cable.

[0025] Working principle: The electric heating cable is fixed to the surface of the pipe 1 to be heated by the connecting post 2. The locking nut 4 is used to press the heating cable body 3 tightly onto the pipe 1 to ensure good heat conduction and mechanical connection. According to actual needs, the density and length of the U-shaped structure of the heating cable body 3 are adjusted to match the heating demand and power requirements of the pipe 1. When the power is turned on, the heating wire 13 between the two sets of busbar bodies 12 starts to heat up. Since the heating wire 13 is arranged in a U-shaped structure on the surface of the electric heating component 11, it can concentrate heat to locally heat the pipe 1. The U-shaped design increases the unfolded area of ​​the heating wire 13, making the heat distribution more uniform and improving the heating efficiency. By observing the color change of the color-changing block 7, the working temperature and heating effect of the electric heating cable can be monitored in real time. The heating temperature can be precisely controlled by adjusting the power supply voltage or changing the installation density of the heating cable body 3 to achieve the purpose of energy saving and high-efficiency heating. The design of the reinforced sheath 14, metal braided mesh 15 and busbar insulation 16 together constitute a multi-layer safety protection system to ensure the stable operation and long-term use of the electric heating cable in harsh environments.
