摘　　要：分析了直接空冷凝汽器管束结构及工作原理,认为空冷凝汽器顺流管束下端比逆流管束更容易结冰。介绍了直接空冷凝汽器管束温度场在线监测系统设计、实施方案,通过实时测量直接空冷凝汽器入口、出口空气温度,可以随时掌握空冷系统运行状态,预判直接空冷散热器可能发生冻结的管束,有效避免直接空冷凝汽器冻结故障的发生,并为直接空冷系统的运行调整及冬季防冻措施的制定提供依据。The anthor a analyzed the cooled condenser, proposed that the control structure and work principle of direct downstream pipes were easily frozen than air the countercurrent pipes. Designed a direct air cooled condenser temperature field online observation system to monitor the inlet and outlet air flow temprature, which could effectively avoide the question of condenser tubes＇ freeze, and provide the reference for the operation adjusting and antifreezing of direct air cooled units.
