The closed cooling tower is a kind of evaporative cooler, which uses the spray water outside the coil to absorb the heat of the cooled fluid inside the coil after partial evaporation. The closed cooling tower uses two stages of cooling: the first stage is air cooling, and the cooler coil is cooled by air; The secondary cooling uses air cooling and spray. When the ambient temperature is relatively high, the secondary cooling is used. The spray system sprays water onto the surface of the cooler while the air cooling, which can take away the heat of the coil when the water evaporates, thus achieving the cooling effect.

The high temperature process fluid in the coil carries out heat exchange with the spray water and air outside the coil to realize cooling. The air flowing from the coil surface under the action of the induced draft fan makes the spray water completely cover the coil surface, and the heat exchange effect of the water is more remarkable by the wind potential. The temperature of spray water and air increases after absorbing heat, and part of water changes from liquid to water vapor. The latent heat of evaporation takes away a lot of heat. The water in the hot air is intercepted by the water baffle and collected into the PVC heat exchange layer. The water in the PVC heat exchange layer is cooled by the transversely flowing air, and the temperature is reduced to enter the water collecting tank, and then sent to the spray water system by the circulating water pump for further circulation.

1. The equipment is slightly large, easy to install and place;
2. The main cooling is coil, and a small part of PVC filler is used as auxiliary cooling. The cost is slightly lower than that of countercurrent tower;
3. The metal outer plate is solid and durable, with strong corrosion resistance. A small part of PVC filler is used as auxiliary cooling, and the cooling capacity is slightly weakened after long-term use;
4. Suitable for medium and low temperature difference cooling.
