摘要
提出了一种用于非能动安全壳冷却系统的新型空气流道结构,鉴于原空气导流板重量大,材料与施工成本高的弊端,新结构大量减少了空气导流板的使用。笔者进一步对两种结构的流场进行了分析,比较出新结构的冷却能力相对原结构有明显提升,验证了新型空气流道结构设计的可行性。
An improvement for air path structure of the passive containment cooling system is introduced in this paper. Thenew structure would cut down the most part of the air deflector which bring on heavy weight and high cost of material and fabri-cation. Through the analysis on both original and new structure flow field,it is shown that the new structure has more efficientcooling performance than the original design,thus it proves the feasibility of the new air flow channel structure design.
