The invention relates to the technical field of hypersonic speed low-density ground test equipment, in particular to a wind tunnel heating section shell and a cooling structure of the free end of an inner shell of the wind tunnel heating section shell. According to the structure, cooling water (liquid) flows into one end of the U-shaped channel from the water inlet channel; then the water flows through the U-shaped channel and flows out from the other end of the U-shaped channel to the water outlet channel; under the condition that both the structural size and the machining process are considered, cooling water (liquid) can flow through the position closer to the end face of the free end of the inner shell, the cooling state of the end face of the free end of the inner shell can be effectively improved, and the service life of the inner shell is prolonged. The cooling structure design of the free end of the wind tunnel inner shell can effectively improve the cooling state of the end face of the free end of th
