The invention discloses an integral water cooled copper crucible. The integral water cooled copper crucible comprises a crucible body composed of a side wall and a bottom wall, wherein a first water inlet in the bottom wall is communicated with a first water inlet connector, a first water outlet is communicated with a first water outlet connector, a second water inlet is communicated with a second water inlet connector, and a second water outlet is communicated with a second water outlet connector; the first water inlet is communicated with a first radiating pipeline, the second water inlet is communicated with a second radiating pipeline, the first radiating pipeline is communicated with an L-shaped first water outlet pipeline in the side wall through a first connecting pipe, the second radiating pipeline is communicated with an L-shaped second water outlet pipeline in the side wall through a second connecting pipe, the first water outlet pipeline is communicated with the first water outlet, and the second water outlet pipeline is communicated with the second water outlet. Due to the arrangement of the radiating pipelines and the water outlet pipelines, the integral water cooled copper crucible can be manufactured conveniently; by the adoption of the double-channel or multi-channel circulating waterway structure, operation requirements of electronic guns with higher power can be met, and high-temperature damage is avoided.
