Abstract: The present disclosure relates to a hypergravity centrifuge device and a temperature control method therefor. The temperature control method for a hypergravity centrifuge device based on steady-state temperature prediction of the present disclosure includes: step S100, providing a hypergravity centrifuge device; step S200, carrying out temperature sampling at designated detection points in the working chamber, and obtaining corresponding temperature sampling vector; step S200, carrying out temperature sampling at designated detection points in the working chamber, and obtaining corresponding temperature sampling vector; step S400, comparing the predicted steady-state temperature with a control temperature and changing a temperature of a cooling medium in the cooling system accordingly; step S500, cycling steps S200-S400 according to a predetermined cycle to make the predicted steady-state temperature tend towards the control temperature.

Abstract: The present application provides a compound refrigeration system for a heat pipe of a supergravity centrifuge. The compound refrigeration system for the heat pipe of the supergravity centrifuge includes a rotor rotating around a vertical axis, an experimental cabin covering outside the rotor, and a corresponding cooling system. 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 includes 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 includes a condensation chamber arranged outside the experimental cabin, and a heat pipe radiator thermally coupled with the rotor.
