[0002] In industrial production, dry air cooler is often used for cooling treatment of various process gases, such as gas cooling in chemical production process. The working principle of dry air cooler is to reduce the temperature of the cooled medium by air convection heat transfer. Specifically, when the medium to be cooled flows in the pipe, the airflow generated by the fan of the dry air cooler flows through the tube bundle and exchanges heat with the medium in the pipe. Due to the temperature difference between air and medium, heat is transferred from the medium with higher temperature to the air with lower temperature, thereby achieving the cooling of the medium.

[0003] When the ambient temperature is too high in summer, the cooling capacity of the dry air cooler is insufficient, so it is necessary to erect a spray pipeline on the upper part of the finned tube of the dry air cooler in a specific area and install a special spray nozzle to disperse the desalted water into a group of liquid droplets that can penetrate the finned tube bundle and fully contact the high-temperature finned tube, thereby improving the cooling effect by using the latent heat of water vaporization.

[0032] The outer wall of the lead screw 16 is symmetrically screwed with two distance adjusting seats 7, and the two distance adjusting seats 7 are respectively fixedly installed on the adjacent ends of the two spray pipes 2. Two external threads with opposite threads and same pitches are formed on the outer wall of the lead screw 16 from the center position to the two sides, and the two distance adjusting seats 7 are respectively connected with the two external threads of the lead screw 16 through the threaded through holes formed in the centers.

[0045] Then, the threaded rod 15 is inserted into the inner cavities of the two abutting seats 6, and then the locking seats 22 are respectively screwed, so that the end portions of the two spraying pipes 2 away from the lead screw 16 are fixed.

[0046] Then, the output shaft of the motor drives the gear 13 to rotate, and the meshing of the gear 13 and the rack track 14 drives the spraying pipe 2 to move from bottom to top along the outside of the air cooler, and at the same time, the spraying pipe 2 sprays and cools the air cooler through the spray heads 3 on the spraying pipe 2.
