摘要: 对喷淋蒸发板式冷凝器的传热性能进行理论分析与实验研究,建立其特性实验系统和模型,着重研究蒸发式冷凝器板外水和空气侧的传热性能,并得出适合喷淋蒸发板式冷凝器的计算关联式,以指导该冷凝器的设计计算和热阻分析.研究表明,湿球温度、板片间距、喷水量和风量均是影响喷淋蒸发板式冷凝器传热性能的主要因素.

Abstract:

Based on the theoretical analysis and experimental investigation of spraying plate- type evaporative con-densers,a performance test system as well as a corresponding model of the condenser was constructed,and the wa-ter- side and the air- side heat transfer performances of the condenser were discussed in detail.Moreover,some cal-culation correlations of the condenser were derived to guide the design and analysis of thermal resistance.It is foundthat wet- bulb temperature,plate spacing,water quantity and wind volume are the main factors that affect the heattransfer performances of spraying- plate evaporative condensers.

Key words: evaporative condenser, spraying plate- type, heat transfer coefficient, calculation correlation, theoreti-cal analysis, experimental investigation
