▎ 摘　　要

NOVELTY - The structure has a satellite protection layer structure (2) that is provided with an outer side heat conducting surface (1) and inner side heat conducting surface (3). The satellite protection layer structure is surrounded by metal layer hollow micro lattice structure. The metal layer hollow micro lattice structure is composed of hollow thin pipe that is arranged according to micro lattice structure. The hollow thin pipe is provided with a phase change material. The hollow thin pipe is made of metal, ceramic, carbon nanotube or graphene. USE - Integrated structure of satellite bearing and heat management ADVANTAGE - The high surface area of the metal layer hollow micro lattice structure increases the thermal conductivity of the phase change material, so as to improve the heat transfer performance, the radiating effect is good and high radiating efficiency is high. The high specific strength and high specific rigidity performance are achieved. The satellite bearing and thermal management integrated structure prevents satellite temperature difference too large caused by performance failure. The highest temperature and lowest temperature difference value is reduced so as to prolong the temperature fatigue life of satellite. The structure of the satellite is kept stable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of integrated structure of satellite bearing and heat management. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing the integrated structure of satellite bearing and heat management.
