Specifically, the physical parameters of the paraffin wax, such as the first phase change point (temperature for starting melting), the second phase change point (temperature for complete melting), viscosity, density and other parameters influencing melting, are adjusted artificially. Then, a thermal control experiment can find that the phase transition temperature range has better linearity (the abscissa is temperature, and the ordinate is the extending displacement of the paraffin temperature-sensing element), and the control of the spacecraft temperature level can be realized by designing a rotating part according to the curve relation between the temperature of the experiment and the extending displacement of the paraffin temperature-sensing element and a design target (the relation between the spacecraft temperature and the area of a radiating surface). In addition, the friction and other physical factors at the sliding seal position can be further considered, the friction force is measured through an experiment, then the physical properties of the paraffin material, the spring stiffness coefficient, the volume of the paraffin and other factors are comprehensively considered, and finally the paraffin temperature sensing element is calibrated through a thermal control experiment, so that the relation between the extension displacement and the temperature of the paraffin temperature sensing element can be accurately obtained, and the self-adaptive control of the temperature level of the spacecraft is realized. The paraffin temperature sensing element 5 can convert temperature change information into force and displacement information and output the force and displacement information, can replace a stepping motor to drive, effectively avoids the problem of failure of the stepping motor, reduces the weight and increases the effective load of a satellite. The invention is an indispensable thermal control technology for the spacecraft to carry out extraterrestrial planet detection and deep space detection, and has great significance to the technical field of thermal control of the spacecraft in China.
