The beneficial effects of the utility model reside in that:

the utility model combines the advantages of high efficiency of air cooling heat exchange and evaporation heat exchange of the air cooler, and adds a wet curtain air cooling module at the air inlet of the air cooler in summer, which can reduce the temperature of the inlet air, achieve the purpose of improving the heat exchange efficiency of the air cooler, and thoroughly solve the problem of insufficient cooling capacity of the air cooler in summer; in addition, the design only needs to cool the outside air in summer, and water resources are not needed in other three seasons, so that the requirement of cooling all the year round can be met, and a large amount of water resources can be saved;

this design can make up the design and use, simple to operate can share circulating water system, and compact structure compares with domestic (and foreign) similar air ware auxiliary cooling technique: in the traditional auxiliary cooling of the air cooler, spray water is additionally arranged above the finned tubes, so that the finned tubes are scaled and filthy-blocked, the subsequent use and the service life of the air cooler are directly influenced, and the operation is very unstable; the air cooler with the air conditioning system adopts the idea of cooling air, the auxiliary system cools the air, and the cooled air cools the finned tubes, so that the finned tubes are not scaled or dirty and blocked, and the operation is stable and reliable; compared with an evaporative condenser, the design saves water by more than 70%; compared with a shell-changing heat exchanger and a cooling tower system, the water is saved by more than 80%.
