Abstract:

The structure of a new divertor cooling module is introduced for EAST superconducting tokamak. By using the FLUENT finite elemente software, the steady state thermal analysis was performed for the model with different parameters so as to quantifictional study the change rule the heat exchanged capacity with its parameters. Preliminary range of the optimized parameters is given for EAST to provide the reference for design and manufacture of water-cooling W/Cu divertor, which is very important to the research of divertor for tokamak and fusion reactor.

摘要：

介绍了EAST超导托卡马克偏滤器的最新冷却模块结构。利用FLUENT有限元软件对不同参数下的模型进行了稳态热分析，定量研究了冷却模块换热能力随各参数的变化规律。针对EAST装置给出了初步优化的参数范围，为水冷钨铜偏滤器的设计制造提供了参考。这对于托卡马克装置及聚变堆偏滤器研究具有十分重要的意义。
