Three-dimensional deformation pipe heat accumulator

The invention provides a three-dimensional deformation pipe heat accumulator, and belongs to the technical field of combustion heat accumulation and heat exchange equipment. The three-dimensional deformation pipe heat accumulator comprises a heat accumulator shell and a plurality of three-dimensional deformation pipes, wherein the three-dimensional deformation pipes are uniformly arranged in the heat accumulator shell in a honeycomb shape. The three-dimensional deformation pipes are spiral flat pipelines, mixing between boundary layers and main fluid mass points is enhanced, and the heat transfer enhancing effect is achieved. The spiral three-dimensional deformation pipes can generate the flow speed higher than that of an existing hexagonal straight-through pipe, the resistance of the same wind is reduced, and therefore, a fan with small power can be selected under the same requirement, energy consumption is reduced; and meanwhile, due to the fact that the flow speed is increased, dust is not prone to being a
