The high-temperature-resistant axial flow fan comprises a shell, a motor assembly and an impeller assembly, flanges are fixedly connected to the edges of the two ends of the shell, a cooling ring is connected between the flanges through a linear driving assembly, a spray head is arranged on the inner wall of the cooling ring, the cooling ring is connected with a liquid guide pipe, and the liquid guide pipe is connected with the motor assembly. A cooling sleeve is connected in the shell through a connecting rod, and a cooling coil is wound on the outer side of the cooling sleeve. According to the high-temperature-resistant axial flow fan, the cooling ring can be driven to reciprocate left and right on the shell through the linear driving assembly, spraying is conducted on the shell through the spray head, the shell is cooled, heat transmitted by the shell to the motor assembly is reduced, and the periphery of the motor assembly is cooled through cooperation of the cooling coil and the cooling sleeve; and the d
