Abstract: The present disclosure relates to a liquid-cooling radiating pipe and a vacuum interrupter with a built-in liquid-cooling radiating pipe, belonging to the field of vacuum circuit breakers. Based on an original structure of an vacuum interrupter, a liquid-cooling radiating pipe of a Tesla valve structure is arranged in a conductive rod of the vacuum interrupter with the built-in liquid-cooling radiating pipe, and liquid metal is used as a circulating coolant in the liquid-cooling radiating pipe, and by using the self-circulating flow of the liquid metal in the pipeline, the capacity of the conductive rod to dissipate heat to the outside is significantly increased, and the problem of excessive internal temperature rise of a vacuum circuit breaker is effectively solved.
