Description

Technical Field

[0001] This utility model relates to the field of heating devices, specifically to a vacuum cavity heating device. Background Technology

[0002] A vacuum chamber heating device is a device used to heat objects, primarily in laboratories and industrial production. Its core function is to uniformly heat objects using various methods, such as steam heating and electric heating, to meet specific processing requirements. A Chinese patent (authorization announcement number CN 117568752A) discloses a high-efficiency vacuum chamber heating device. This patented technology has a simple and reasonable structure, fast heat conduction speed, uniform heating, and high heating efficiency. However, its insulation effect is poor. Using an inert gas as the heat radiation medium, the accumulation of inert gas within the heater occupies effective heat transfer space, leading to reduced heat exchange efficiency. Furthermore, the inert gas does not participate in phase change or endothermic processes, thus limiting the temperature rise of the heating medium, resulting in poor heating efficiency. Therefore, those skilled in the art have provided a vacuum chamber heating device to address the problems mentioned in the background art. Summary of the Invention
