Abstract:The high-level water collecting cooling tower is a new type of cooling tower based on natural ventilation countercurrent wet cooling tower.The structure principle of high-level water collecting cooling tower is introduced.According to the study of scholars,the changes of air flow field inside and outside the high-level water collecting cooling tower are compared in the absence of ambient crosswind and various common wind speeds.Finally,it is proposed that the environmental crosswind has a negative impact on the high-level water collecting cooling tower,and optimization researches should be carried out in the aspect of eliminating or reducing the damage of crosswind to the symmetry of the internal and external flow fields of the cooling tower.
