The cooling tower Tower) is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce water temperature. Its cooling is a device that uses the flow of water and air to exchange heat and cold to generate steam. The steam volatilization takes heat to evaporate, convective and radiant heat to dissipate the waste heat produced in industry or refrigeration and air conditioning to reduce the evaporation and dissipation of water temperature Thermal device, to ensure the normal operation of the system, the device is generally barrel shaped, so it is called cooling tower.

The square cross flow cooling tower adopts the air inlet at both sides and the fan at the top to make the air exchange with hot water through the fillers at both sides of the tower, and the hot and humid air is discharged to the outside of the tower. The point wave plate with convex points on both sides of the filler is used. The point wave plate is bonded as a whole through the installation head to improve the rigidity. The convex points on both sides can also avoid direct water dripping, so the water film forming ability is improved. Water collection measures are set at the tail of the filler.
