Heat pipes (HP) are considered being used in the divertor target because of their high thermal conductivity and their capability to substantially enlarge the heat transfer area to the cooling circuit. Here, a divertor target concept based on a heat pipe design is introduced being able to dissipate heat fluxes of up to 20 MW/m². It consists of a 230 mm long water-based heat pipe with a capillary structure that combines axial grooves with sintered porous material. The analysis of the integration of the HP in the divertor target indicates that design changes of the current divertor cassette design are required to accommodate such a solution.

基于热管技术的欧洲DEMO偏滤器等离子面对部件概念

热导管（HP）被认为用于偏滤器靶中，因为它们的导热系数高，并且能够显着扩大到冷却回路的传热面积。在此，介绍了一种基于热管设计的散流器目标概念，该概念能够消散高达20 MW / m ^2的热通量。它由230毫米长的水热管构成，该热管具有毛细管结构，该结构将轴向凹槽与烧结多孔材料结合在一起。对HP在分流器目标中的集成度的分析表明，要适应这种解决方案，需要对当前分流器盒设计进行设计更改。
