Technical Field
[0001] This utility model relates to the field of heating tube technology, and in particular to a single-head heating tube structure. Background Technology
[0002] A heating element is a tubular electric heating element that converts electrical energy into heat energy. It consists of a metal tube, a heating wire, and an insulating filler material. The heating wire generates heat when energized, and the heat is transferred to the metal tube through the insulating material, thus heating air, liquids, and solids. It is used in heating equipment and features simple structure, high thermal efficiency, and ease of use.
[0003] The single-ended heating element features a single-end cable exit structure, making it suitable for scenarios with limited space and requiring localized deep heating. Its sealed design prevents leakage and moisture, making it suitable for liquid and humid environments. Compared to double-ended tubes, it offers more flexible installation, allowing direct insertion into the heating element, reducing space occupation, and facilitating maintenance and replacement. It also meets the size and installation method restrictions of specific equipment for heating elements.
[0004] Traditional heating elements, due to their symmetrical structure, require fixation at both ends. Installation on curved or irregular surfaces necessitates complex supports and is prone to loosening due to vibration, affecting heating stability and ease of installation. Current technology utilizes single-ended heating elements, eliminating the need for fixation at both ends. This simplifies installation on curved and irregular surfaces, reduces reliance on complex supports, lowers the probability of loosening due to vibration, and improves installation adaptability. However, in practical use, when high power output is applied, the limited space for the internal heating wire and filling material means that heat may not be promptly transferred to the heated object. This heat concentration can lead to localized overheating, shortening the lifespan of the heating element and compromising its long-term stable operation. Utility Model Content
