The function of cooling tower packing in cooling tower is to increase heat dissipation, prolong cooling water residence time, increase heat transfer area and increase heat transfer. Evenly distribute water. It is not filling something in a tower that needs to cool down. The cooling tower is a device for cooling the hot fluid (including water) to a reasonable temperature. Waste heat generated in the process of industrial production or refrigeration is usually guided by cooling water. The function of cooling tower is to exchange heat between cooling water with waste heat and air in the tower, so that waste heat is transferred to air and diffused into the atmosphere.
