Liquid cooling radiating pipe and vacuum arc-extinguishing chamber with built-in liquid cooling radiating pipe

The invention relates to a liquid cooling radiating tube and a vacuum arc-extinguishing chamber with the built-in liquid cooling radiating tube, and belongs to the field of vacuum circuit breakers. On the basis of the original structure of the vacuum arc-extinguishing chamber, the liquid cooling radiating pipe with a Tesla valve structure is arranged in the conducting rod of the vacuum arc-extinguishing chamber with the built-in liquid cooling radiating pipe, liquid metal is adopted as circulating cooling liquid in the liquid cooling radiating pipe, and the capacity of the conducting rod for radiating heat to the outside is remarkably improved by utilizing self-circulation flowing of the liquid metal in a pipeline; the problem that the temperature rise in the vacuum circuit breaker is too high is effectively solved. 本发明涉及一种液冷散热管及内置液冷散热管的真空灭弧室，属于真空断路器领域。内置液冷散热管的真空灭弧室在真空灭弧室原有结构的基础上，在其导电杆内设置特斯拉阀结构的液冷散热管，并在液冷散热管内采用液态金属作为循环冷却液，利用液态金属在管道内自循环流动，显著增大导电杆向外部散热的能力，有效解决真空断路器内部温升过高的问题。
