The invention relates to a heat protection structure of a dredging coupling semi-open type dissipation structure, which belongs to the technical field of heat protection of high-speed aircrafts and comprises a dredging structure shell, a dredging structure capillary core body, a dredging structure working medium, a semi-open type dissipation structure, a semi-open type dissipation working medium, a semi-open type dissipation structure exhaust pipe and a semi-open type dissipation structure control switch. Aiming at a local high-heating part of a hypersonic aircraft, on the basis of semi-active dredging type uniform-temperature heat protection, phase change heat absorption and discharge heat dissipation of an active dissipation working medium are combined, and heat absorption and dissipation ways are increased, so that the total heat amount is effectively reduced while the internal heat distribution of the structure is optimized, and the heat dissipation efficiency is improved. Internal heat control and management of the structure are realized through coupling of dredging semi-active heat protection and active dissipation, the problem of non-ablative heat protection in an extreme environment is solved, and a feasible heat protection technical approach is provided for performance improvement of high-speed aircrafts in the future.
