During the working process of the special cooling tower for the intermediate frequency of the pipe bending machine, the cooling medium (soft water, oil or other liquid) is driven by the main circulating pump to circulate between the heat exchanger and the equipment to be cooled, and the spray water is evenly sprayed on the heat exchanger. , A uniform water film is formed on the outer surface of the heat exchanger. The cold air enters the tower from the air inlet below the tower body, and flows countercurrently with the spray water through the surface of the heat exchanger. There are two heat exchange methods in this process, namely, cold air. The heat conduction between the air and the cooling medium and the heat exchange of the evaporation and heat absorption of the spray water, the saturated hot and humid air after absorbing the heat is discharged into the atmosphere by the fan, and the other spray water flows into the water tank at the bottom of the tower body, and is transported by the water pump. To the spray system, the cooling medium in the reciprocating heat exchanger is cooled down.
