Cylindrical structure gradual-change fin phase change heat accumulator

The invention belongs to the technical field of heat accumulation, and particularly relates to a cylindrical structure gradual-change fin phase change heat accumulator. The heat accumulator comprises an upper end face (1), a heat accumulation shell (2), annular fins (3), heat exchange pipe bundles (4), a phase change material (5) and a bottom face (6). The heat exchange pipe bundles are vertically arranged between the upper end face and the lower end face in a peripheral array mode and are arranged at equal intervals in parallel. The annular fins are parallel to the upper end face and the lower end face and horizontally arranged between the upper end face and the lower end face, each level of annular fins is connected with all the heat exchange pipe bundles to form a sealed channel, and heat exchange fluid flows in the channel. The heat accumulation shell wraps a cylindrical space between the upper end face and the bottom face, and the phase change material is stored in the cylindrical space. The intervals of the annular fins are changed gradually, the more the annular fins are close to the bottom face, the intervals are smaller, the heat exchange temperature difference of the heat accumulator more tends to be consistent, and the phenomena that the phase change material is partially excessively hot, and the heat stress of a heat accumulation container is excessively high are reduced.
