Impeller structure and distributor

The utility model relates to the technical field of refrigeration, in particular to an impeller structure and a distributor. The impeller structure comprises an impeller ring, a sprue spreader and a plurality of blades, wherein the sprue spreader and the impeller ring are concentrically or approximately concentrically arranged; the multiple blades are sequentially distributed in the circumferential direction of the sprue spreader, located between the sprue spreader and the wheel ring and connected with the sprue spreader and the wheel ring. The gas-liquid two-phase refrigerant mixing device has the advantage that the gas-liquid two-phase mixing effect of refrigerants is improved. 本申请涉及制冷技术领域，特别是涉及一种叶轮结构及分配器。该叶轮结构包括轮环、分流锥及多个叶片，分流锥与轮环同心或趋于同心设置；多个叶片沿分流锥的周向依次分布，且叶片位于分流锥与轮环之间，并分别与分流锥及轮环相连接。本实用新型的优点在于：提高了制冷剂气液两相的混合效果。
