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 working fluid (water or other liquid) is circulated in the coil of the closed cooling tower, and the heat of the working fluid is dispersed into the spray water flowing through the coil. the external spray water reaches the purpose of cooling the process fluid inside the coil by contacting and exchanging heat with the coil and packing, and then falls into the lower water tank, which is sent by the spray pump to the spray water tank for re-circulation.
the cooling water in the internal circulation exchanges heat and mass with the spray water and air outside the pipe through the coil, avoiding the water pollution caused by the direct contact between the cooling water and the air. because the spray water is pre-cooled by pvc filler, its heat exchange effect becomes obvious.

1. it needs to be assembled on site and covers a large area;
2. the metal outer plate is solid and durable, with strong corrosion resistance, and pvc filler as auxiliary cooling, with low cost;
3. suitable for cooling with medium and low temperature difference.
