摘要: Considering utilization of the original chromium-bronze material, two processing techniques including hydraulic expansion and high temperature vacuum welding were proposed for optimization heat-sink structure in EAST. The heat transfer performance with or without cooling tube was calculated different types connection between compared by conducting a special test. It is shown from numerical analysis that diameter channel can be reduced 12 mm to 10 mm. Compared sample, thermal contact resistance sample reduce 10%, while 20% sample. However, technique more complicated expensive than technique. Both prototype should further considered
