Description

Technical Field

[0001] The utility model relates to the technical field of vacuum heating equipment, in particular to a heating tube vacuum heating device. Background Technique

[0002] In the cutting-edge field of heating equipment technology, vacuum heating devices rely on their efficient and uniform heating characteristics achieved under low-oxygen to oxygen-free conditions. The core of such devices is a carefully designed vacuum chamber, equipped with advanced heating elements, which, relying on innovative installation architectures and intelligent temperature control systems, ensure precise temperature regulation.

[0003] However, vacuum heating devices also face challenges in practical applications. On the one hand, some heating tube materials are prone to oxidation and corrosion in high-temperature vacuum environments, thereby affecting heating efficiency and shortening service life. On the other hand, the sealing performance between the heating tube and the vacuum chamber is directly related to the stability of the vacuum degree and the heating effect. Poor sealing will cause air leakage and temperature fluctuations, thereby affecting the overall performance. In addition, the layout method and support structure of the heating tubes are also key factors. An unreasonable design is likely to lead to uneven temperature distribution in the heating chamber, affecting the stability of product quality. In extreme high-temperature and vacuum working environments, the safety and stability of the equipment cannot be ignored, but some existing devices are still insufficient in terms of safety protection.
