Abstract: In order to solve the high heat generation of equipment in coal mines, which causes a heavy burden on the water supply and drainage system, as well as the easy scaling problem of equipment heat exchangers, an innovative solution based on reverse flow closed-type cooling tower was proposed. This solution was developed by using Fluent software from Ansys for fluid mechanics and thermodynamics research and optimization design. The study showed that the boundary of the water collector baffle can be passivated and the guide plate can be reasonably set to effectively improve the water-collecting efficiency and reduce the water consumption. The reverse flow closed-type cooling tower can save about 700 tons of water per day, and there is no scaling phenomenon in the cooler.
