This invention discloses an azeotropic phase change cooling rotor assembly, a Roots compressor, and a vacuum pump. The rotor assembly includes a main rotor with circumferentially shaped through-holes and an axially oriented internal through-hole on the rotor shaft. A first and a second auxiliary rotor are mounted at both ends of the main rotor. Rotor sealing plates are arranged on the inner sides of the two auxiliary rotors to seal the shaped through-holes and form a first azeotropic flow region. One end of the rotor shaft is connected to a drive motor, and the other end connects to a swirl cooling pipe with swirl fins on its outer wall, forming a second azeotropic flow region through end sealing. The first and second azeotropic flow regions are filled with an azeotropic phase change cooling medium. This invention is based on the azeotropic phase change heat transfer principle and combines a swirl cooling structure to achieve efficient heat dissipation. The overall structure is simple and compact, eliminating the need for complex cooling equipment, effectively suppressing rotor temperature rise during operation, and avoiding rotor jamming caused by high-temperature thermal expansion.
