[0003] The main principle of a closed cooling tower is that the spray water evaporates on the outer wall of the coil to cool the cooling water flowing through the tube, and at the same time, the fan is used to take away the generated water vapor in time. A small part of the spray water evaporates, and the rest is collected by the chassis and recirculated. The cooling water with a higher temperature coming out of the condenser is pressurized and transported to the cooling coil of the closed cooling tower by the cooling water pump. On the other hand, the water in the chassis of the cooling tower is sucked into the spray coil by a pipeline pump, and the water sprayed on the outer surface of the cooling coil vaporizes and absorbs the heat of the cooling water in the coil, thereby reducing the temperature of the cooling water. At the same time, the suction effect of the fan installed on the water retaining plate makes the air flow through the cooling coil from bottom to top, and exchanges sensible heat and latent heat with the spray water, which can not only enhance the heat release of the outer surface of the cooling coil, but also take away the water vapor formed by evaporation in time, accelerate the evaporation of water, and improve the cooling effect.

[0004] The cooling coil is mainly realized by bending the pipe. It is troublesome to adjust how to bend the pipes of different sizes and the bending angle. Utility Model Content
