Abstract: To enhance the heat transfer and flow，both special-shape tubes including bullet-tube and twist-tube were used in the evaporative condenser，and compared with the existing round-tube. An experimental system wasset up，heat transfer coefficient and power performance of the evaporative condenser were investigated with changing operation parameters. The results indicated that heat transfer coefficient and power performance were better when the sprayed water flow rate ranged 0.05—0.065 kg/(m·s) and airflow velocity ranged 2.6—3.4 m/s. The heat transfer coefficient of the bullet-tube was 9.2%—19.0% higher than that of round-tube，while the power decreased by 2.6%—4.9%. The heat transfer coefficient of the twist-tube was 18.0%—33.1% higher than that of round-tube，and the power increased by 2.6%—4.9%. Finally，the two new types of evaporative condenser were used in industry with obvious energy and water saving.

摘要： 提出了弹形管和扭曲管提升蒸发式冷凝器性能，测试了冷却水喷淋密度和风速对传热与能耗性能的影响，并与圆管进行了对比。结果表明，水喷淋密度和空气流速对蒸发式冷凝器性能均有重要影响，适宜传热的水喷淋密度为0.05～0.065 kg/(m·s)，适宜的风速为2.6～3.4 m/s；弹形管比圆管的传热系数高9.2%～19.0%而能耗低2.6%～4.9%，扭曲管比圆管的传热系数高18.0%～33.1%同时能耗高2.6%～4.9%。以实验结果为基础，将蒸发式冷凝器在工业中应用，起到良好的节能节水效果。
