The invention discloses a centrifugal rotational flow hollow rotatable nozzle device, and belongs to the technical field of air conditioning refrigeration. The centrifugal rotational flow hollow rotatable nozzle device comprises a centrifugal rotational flow hollow nozzle, a connecting rod, a fixed shaft and a conical water distribution plate. The conical water distribution plate is arranged in amounting groove of the fixed shaft through a central circular ring. The central circular ring is in clearance fit with the mounting groove. The conical water distribution plate can freely rotate. After the centrifugal rotational flow hollow nozzle acts on the cooling water, some of the cooling water collides with an inclined baffle above the conical water distribution plate to generate thrust, sothat the conical water distribution plate rotates around the fixed shaft; meanwhile, after the rest cooling water collides with the conical vertical surface of the rotating conical water distributionplate and then flows downwards in sequence from water distribution holes in a distributed manner to wrap positions below the nozzle. The centrifugal rotational flow hollow rotatable nozzle device caneffectively alleviate the large-amount distribution of water on the side, close to an inlet, of a single-side tangential inlet centrifugal rotational flow hollow nozzle, and enables more even water distribution within a spraying range.
