Description

Technical Field

[0001] The utility model relates to the technical field of heating wires, in particular to a heating wire fixing structure. Background Art

[0002] Heating wire technology converts electrical energy into thermal energy through the principle of resistive heating and is widely used in industries, homes, and scientific research. Its main component is the heating wire, which is usually made of high-resistance materials such as nickel-chromium alloys and iron-nickel alloys. These materials can quickly heat up and maintain high temperatures when powered on. Currently, heating wires are usually installed in a fixed manner. As the heating wire heats up, its material undergoes thermal expansion. When the material is heated, the movement of atoms or molecules intensifies, the spacing between them increases, and the overall volume of the material expands, causing the heating wire to overheat and deform. The fixed installation method of the heating wire makes it impossible to effectively remove the heating wire, necessitating the replacement of the entire heating wire, which increases the corresponding cost. At the same time, if certain fixed protective measures are not taken on the outer wall of the heating wire, it is easy for the thermally deformed heating wire to expand externally, causing damage to other external equipment or devices, thereby reducing the use effect of the heating wire and indirectly affecting the durability and stability of the heating wire.

[0003] Therefore, it is necessary to develop a heating wire fixing structure. Utility Model Content
