Abstract: Disclosed is an integrated washing and spinning tub and an energy-saving and healthy household washing machine with a tub replacing function. The integrated washing and spinning tub comprises a water holding tub, a spinning tub is arranged in the water holding tub, and the water holding tub and the spinning tub are connected in a sliding groove mode. The energy-saving and healthy household washing machine with a tub replacing function comprises a washing machine shell, the integrated washing and spinning tub is arranged in the washing machine shell, a spring telescopic support corresponding to the integrated washing and spinning tub is arranged on the inner wall of the upper portion of the washing machine shell, a support frame is arranged at the bottom of the integrated washing and spinning tub, and a reduction gear and a motor which are connected are arranged on the support frame.

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.
