Numerical Simulation and Analysis of a Vertical Tube Indirect Evaporative Cooler
The heat transfer enhancement of the vertical type indirect evaporative cooler is more convenient and occupies less space.However,the efficiency of t the vertical type indirect evaporative cooler is reduced due to the uneven distribution of water film on the inner wall of the pipe.In this paper,three-dimensional full-size numerical simulation research method is used to simulate and analyze the performance,structure,operation and other parameters of the vertical tube indirect evaporative cooler with internal groove,and obtain a more reasonable structure configuration and corresponding operating conditions.It is found that when the environmental parameter is 29℃,humidity is 45%,pipe diameter is 25mm,and relative pipe spacing is 2.The pipe length is 1m,the primary wind speed is 2.5m/s,and the secondary wind speed is 13m/s.Under this condition,the heat transfer effect is obvious.
