Novel radial pulsating heat-pipe for high heat-flux thermal spreading

•Novel radial pulsating heat-pipe (RPHP) has been proposed as a thermal spreader.•The feasibility and the underlying thermal performance of the proposed RPHP was experimentally investigated.•RPHP successfully spread heat and dropped the hot-spot temperature compared to its pure conduction.•Further s...
