The main-auxiliary combined indirect dry cooling system has attracted attention from the industry in recent years, while few scholars at home and abroad have conducted studies on its flow and heat transfer performances. In order to investigate the transport characteristics of the main-auxiliary combined indirect dry cooling system under different configurations, this paper establishes six physical models of the combined indirect dry cooling systems with the double-layer/single-layer main and auxiliary radiators. And then the cooling performances are analyzed and compared using the commercial software FLUENT. The results show that, the construction has obviously higher impacts on the auxiliary cooling system than the main one, meanwhile the air mass flow rate presents larger difference than the heat rejection; In absence of wind, the main-auxiliary combined cooling system with double-layer heat exchanger arrangement, has better cooling performance than that with the single layer heat exchanger arrangement, and case A possesses the best cooling performance; Under crosswind effects, case C has highest cooling capability of the auxiliary cooling system, while the behavior of its main cooling system should also be considered before the engineering selection. This research may provide some theoretical guidelines for the engineering design and application of the main-auxiliary combined natural draft dry cooling system.

主辅机合建式间接空冷系统近年引起了业内关注，目前国内外学者对其流动换热性能开展研究较少。为探究不同构型条件下主辅机合建式间接空冷系统的输运特性，本文建立了6种主辅机散热器双层布置和单层布置的合建式间接空冷系统物理模型，并借助商业软件FLUENT模拟对比分析了不同构型的输运性能。研究结果表明：系统构型对辅机冷却系统的输运性能影响远高于主机冷却系统，且相对于换热性能，流动性能更易受到影响；无风情况下，双层布置主辅机冷却系统的输运性能均优于单层布置，且构型A的辅机冷却性能最佳；在环境风影响下，构型C的辅机冷却性能远高于其他构型。该研究可为主辅机合建式间接空冷系统工业设计及应用提供理论指导。

主辅机合建式间接空冷系统近年引起了业内关注，目前国内外学者对其流动换热性能开展研究较少。为探究不同构型条件下主辅机合建式间接空冷系统的输运特性，本文建立了6种主辅机散热器双层布置和单层布置的合建式间接空冷系统物理模型，并借助商业软件FLUENT模拟对比分析了不同构型的输运性能。研究结果表明：系统构型对辅机冷却系统的输运性能影响远高于主机冷却系统，且相对于换热性能，流动性能更易受到影响；无风情况下，双层布置主辅机冷却系统的输运性能均优于单层布置，且构型A的辅机冷却性能最佳；在环境风影响下，构型C的辅机冷却性能远高于其他构型。该研究可为主辅机合建式间接空冷系统工业设计及应用提供理论指导。

The main-auxiliary combined indirect dry cooling system has attracted attention from the industry in recent years, while few scholars at home and abroad have conducted studies on its flow and heat transfer performances. In order to investigate the transport characteristics of the main-auxiliary combined indirect dry cooling system under different configurations, this paper establishes six physical models of the combined indirect dry cooling systems with the double-layer/single-layer main and auxiliary radiators. And then the cooling performances are analyzed and compared using the commercial software FLUENT. The results show that, the construction has obviously higher impacts on the auxiliary cooling system than the main one, meanwhile the air mass flow rate presents larger difference than the heat rejection; In absence of wind, the main-auxiliary combined cooling system with double-layer heat exchanger arrangement, has better cooling performance than that with the single layer heat exchanger arrangement, and case A possesses the best cooling performance; Under crosswind effects, case C has highest cooling capability of the auxiliary cooling system, while the behavior of its main cooling system should also be considered before the engineering selection. This research may provide some theoretical guidelines for the engineering design and application of the main-auxiliary combined natural draft dry cooling system.
