Technical Field

[0001] The utility model relates to the technical field of comprehensive coating, in particular to a surface coating device for an electric heating pipe. Background Art

[0002] Heating tubes, also known as tubular electric heater elements, heating tubes, or heating pipes, are electrical components that convert electrical energy into heat. They typically consist of a metal tube (such as stainless steel or copper), resistance wire, and insulating material. Their structural features include a metal tube that acts as a protective and supportive outer shell. The resistance wire is evenly distributed along the central axis of the tube, forming a spiral pattern to generate heat. The spaces between the resistance wires are filled with an insulating material with excellent insulation and thermal conductivity, such as magnesia.

[0003] Compared with the existing technology: the existing electric heating tube surface coating device cannot make the electric heating tube rotate while coating, which may affect the uniformity of the coating. Static coating may cause the coating to be unevenly distributed on the surface of the electric heating tube, with some areas being too thick and other areas being too thin or even without coating. The uneven coating not only affects the appearance of the electric heating tube, but also may affect its performance, such as thermal conductivity and anti-corrosion performance.

[0004] Therefore, a surface coating device for an electric heating tube is proposed. Utility Model Content
