The invention discloses a monopole coaxial pulse tube refrigeration device of an annular pulse tube structure and a design method thereof. The device comprises a hot-end heat exchanger, a cold-end heat exchanger, an annular pulse tube arranged at the outside, a cylindrical heat regenerator internally coaxial with the pulse tube and the like. According to the device, the annular pulse tube structure is adopted, through the slit structure, the phenomenon that the pulse tube performance is deteriorated due to circulation of working gas alternating in the pulse tube and other reasons is reduced, and the performance of the pulse tube and even the performance of a complete machine are improved; a cold finger can be designed into an annular groove structure or a boss structure, coupling with equipment needing to be refrigerated is more facilitated, the refrigeration time is shortened, and the refrigeration efficiency is improved; the manufacturing process difficulty of the complete machine equipment is lowered, the production efficiency is improved, and the design and machining cost is reduced.
