Water spray cooling device for high-altitude simulated test bench

The invention relates to a water spray cooling device for a high-altitude simulated test bench. The water spray cooling device comprises a central body and a plurality of water spray pipes, wherein the central body is positioned on a central axis of a housing of the high-altitude simulated test bench; the middle of the central body is cylinder-shaped, and the two ends of the central body are cone-shaped; the tops of cones are processed into arc shapes; one end of each water spray pipe is connected with the central body through a bolt, and the other end of each water spray pipe is connected with the housing of the high-altitude simulated test bench through a flange; water inlets of the water spray pipes are positioned at the ends of the water spray pipes, which are connected with the housing; and a plurality of water spray holes are formed on the water spray pipes. By adopting the device, high temperature gas can be evenly mixed with water drops on the same cross section, thereby achieving an effect of rapid t
