Embodiment Construction
[0040] A modular and reconfigurable approach to satellite thermal control based on repeatable separable thermal interfaces such as figure 1 As shown, by modularizing the satellite equipment according to the heat consumption level and load heat flux density, two levels of classification can be carried out, and different heat control measures can be taken. The specific steps are as follows:
[0041] (1) Carry out modular division according to the heat consumption of satellite equipment and load heat flux;
[0042] In the modular division, the following principles are followed:
[0043] Classify the modules of the modular reconfigurable satellite according to the heat consumption level and load characteristics, the heat consumption is less than 150W, and the load heat flux density is less than 1W / cm 2 The module is the first type of module; the heat consumption is less than 150W, and the load heat flux is between 1W / cm2 with 3W / cm 2 The modules in between are the second type mo...

A modular reconfigurable satellite thermal control method based on repeatable separation of thermal interfaces, starting from the design of modular reconfigurable satellite systems, classifying modules according to their heat consumption levels and load characteristics, and adopting different thermal control measures, respectively. Design three reproducibly separable thermal interfaces such as solid-solid thermal interface, liquid circuit interface and gas-liquid interface, as well as enhanced heat transfer measures such as graphene coating film and flat heat pipe, establish thermal connection between assembly and reconstruction system, and realize the decentralization of the entire satellite system. Distributed heat dissipation provides coordinated heat dissipation of heat dissipation pathways, enhancing the heat dissipation capabilities of individual modules and satellite systems.
Description
technical field [0001] The invention relates to a modular reconfigurable satellite thermal control method based on a repeatable separable thermal interface, which belongs to the field of thermal control. Background technique [0002] With the gradual expansion of the breadth and depth of space utilization in my country and other countries in the world, the demand for satellite development has been continuously enriched and improved. On the one hand, the demand for large or super-large satellites continues to emerge, including super-large telescopes, super-large space antennas, and long-baseline space survey missions. 100 tons, due to the limitation of the envelope of the launch vehicle fairing and launch weight, it is difficult to meet the development needs of this type of satellite; The one-time working method of the end has not adapted to the rapid development of space technology. In this case, reconfigurable satellites have gradually become an important direction for th...
