1. A compound refrigeration system for a heat pipe of a supergravity centrifuge, comprising a rotor rotating around a vertical axis, an experimental cabin covering outside the rotor, and a corresponding cooling system, wherein the rotor is provided with a shaft part which is in running fit with the experimental cabin; the shaft part is provided with a shaft top end located outside the experimental cabin; the cooling system comprises a liquid cooling device and an evaporative cooling device;
the liquid cooling device comprises a refrigeration source, and a first cooling medium circulating pipeline communicated with the refrigeration source and thermally coupled with a cabin wall of the experimental cabin;
the evaporative cooling device comprises a condensation chamber arranged outside the experimental cabin, and a heat pipe radiator thermally coupled with the rotor; a heat absorption end of the heat pipe radiator is fixed to the rotor; and a radiating end of the heat pipe radiator extends into the condensation chamber through the shaft top end.
