| Abstract: |
This paper describes the research and design phase for a heat exchanger component for a magnetically confined fusion energy device. This process involved an iterative process going through design and analysis using the finite element method, manufacturing trials and experimental testing. The component in question, called a monoblock, consisted of a CuCrZr cooling pipe joined to external W armour. To reduce thermally induced stresses in the pipe a solid copper section was introduced as an interlayer between pipe and armour. To further reduce stress, geometric features were machined into the interlayer to produce a more favourable thermal profile within the component. Joining was achieved with a two-stage brazing process and thermal testing was performed as IPP's GLADIS facility. The component assemblies were tested to 200 cycles at 20 MW m−2 and five cycles at 25 MW m−2. No damage was observed after testing. |
