The invention provides a low-speed cooling water thermal protection device and relates to the technical field of aircraft heat shielding ground testing. The low-speed cooling water thermal protection device comprises a water collecting cavity, a water inlet, a water outlet and water cooling channels. The water collecting cavity is of a hollow cylindrical structure. The water inlet is fixedly installed at one end of the outer wall of the water collecting cavity, and the water outlet is fixedly installed at the other end of the outer wall of the water collecting cavity. The multiple adjacent water cooling channels are arranged between the outer wall and the inner wall of the water collecting cavity in the axial direction of the water collecting cavity. Channel connection of cooling water of the water inlet and cooling water of the water outlet is achieved through the water cooling channels. By the adoption of the subcooled boiling design method, long-term thermal protection on a diffuser in the megawatt-grade t
