Description

Technical Field

[0001] The utility model patent relates to the technical field of heat dissipation of vacuum furnaces, and mainly relates to a water circuit of an in-furnace radiator for a vacuum furnace. Background Art

[0002] A vacuum furnace is a device that heats in a vacuum environment. The heating system in the furnace can be directly heated by a resistance furnace wire or by high-frequency induction heating. The maximum temperature can reach about 3000°C. It is mainly used for ceramic sintering, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing. Since the temperature in the furnace cavity is particularly high, a good heat dissipation system is required;

[0003] However, the conventional radiator water channel structure is complex, difficult to form, and requires a large amount of processing. In addition, the contact between the water channel pipeline and the vacuum furnace will cause the temperature of the outer wall of the pipeline to be too high, making the pipeline easy to be damaged, affecting the service life of the pipeline and increasing the cost. In this regard, we propose an in-furnace radiator water channel for a vacuum furnace. Utility Model Content
