We designed a two-stage graphite thermal Tesla valve adapting the concept of the Tesla valve from fluid dynamics. We observed an enhanced thermal rectification ratio of 1.22 using the unique phonon hydrodynamic approach. It paves the future orientation for the development of a high-efficiency thermal diode.
