Circulating water-cooled electrode stem

The utility model discloses a circulating water cooling electrode stem, which comprises an electrode stem body, an air cooling component is wrapped outside the electrode stem body, a water cooling component is embedded in the air cooling component, and the air cooling component and the water cooling component are correspondingly arranged. The cooling channels are circularly distributed outside the electrode body, so that comprehensive cooling of the electrode body is realized, multiple cooling treatment of the electrode body is realized under the matching of the cooling channels and the air cooling sleeve, the cooling precision is enhanced, the condition of larger cooling dead angles caused by non-uniform distribution of a single water cooling pipe is avoided, and the service life of the electrode body is prolonged. And under the cooperation of the heat exchange part, the heat dissipation plates are distributed in the cooling channel, heat is absorbed through the heat dissipation pieces, the heat is transmitt
