Cheaper and higher efficiency heat sinks are needed for future fusion energy devices. Existing heat sink materials cannot achieve higher heat flux operation without costly efficiency enhancements for heat transfer in water and gas cooled components. This project will fabricate advanced heat sink materials, such as CuCrNb, tungsten, molybdenum, and niobium alloys, to near net shape for high flux testing. Also, heat transfer enhancements will be built into the internal cooling passages during heat sink formation. Phase I will demonstrate the forming of plasma facing components with enhanced heat transfer and advanced materials. Divertor mockups will be produced for high heat flux testing. The advanced heat sinks will be cheaper and have higher heat flux operational capabilities than currently produced components.
Commercial Applications and Other Benefits as described by the awardee: Applications for these heat sinks include heat pipes, rocket engines, combustors, chemical processing equipment, nose cones, counterweights, power generation systems, furnace components, x-ray, sputter and beam targets.
