The invention belongs to the field of refrigeration equipment, and particularly discloses a vehicle circulating water cooling tower. The vehicle circulating water cooling tower includes a water storage pool and supports, the water storage pool is internally provided with division plates, the top ends of the division plates are provided with a guide plate in a hinged mode, and the inner wall of thewater storage pool is provided with electromagnets; the inner wall of the water storage pool is further slidably connected with floating balls, the guide plate is slidably connected with a clump weight, and a water storage unit includes a water outlet and a mud outlet; the water storage unit further includes a spring which is fixedly connected at the bottom of the water storage pool, the upper end of the spring is fixedly provided with a vibrating plate, and the lower end of the vibrating plate is connected with a rack; a first rotating shaft is provided with a gear which is meshed with the rack, the first rotating shaft is further provided with a first bevel gear, and a second rotating shaft is provided with a second bevel gear which is meshed with the first bevel gear; and the second rotating shaft extends in the bottom of the water storage pool in a penetrating mode, and the portion, extending in the water storage pool, of the second rotating shaft is connected with a plurality ofscraping plates in the circumferential direction. According to the technical scheme, the problem that a cooling water liquid circulating pipeline needs to be closed when sludge in a cooling tower is cleaned, thereby generating economic losses is solved.
