The theoretical analysis of the heat transfer limit of coaxial thermosyphon with cold neutron source is deduced. The theoretical calculation formula of the heat transfer limit of coaxial thermosyphon is deduced and the existing experimental data are used for fitting. A simple calculation method is proposed, The structure design of hydrogen thermosyphon with cold neutron source is shown. The calculation shows that when the inner diameter of the thermosyphon outer tube is 54 mm and the inner diameter of the inner tube is 21 mm, the heat transfer capacity is 3 kW.
