The multifunctional outer cabin plate lattice structure mainly comprises an inner cabin plate, an outer cabin plate, side wall plates, embedded heat pipes, a rod-shaped regular tetrahedron lattice structure and anti-shearing bearing rods, a satellite single machine is installed on the inner cabin plate, and the outer cabin plate is in direct contact with the vacuum environment and serves as a heat dissipation plate. The pre-buried heat pipes are all installed on the inner surface of the inner cabin plate, the fin faces of the pre-buried heat pipes are tightly attached to the inner surface of the inner cabin plate, the contact area is increased, and the heat exchange efficiency is improved. The overall appearance of the rod-shaped regular tetrahedron lattice structure is of a regular tetrahedron structure, and the unit cell structure is similar to a diamond single crystal. A rod-shaped regular tetrahedron lattice structure is adopted, and a plurality of stable triangular structures are formed among support arms in lattice unit cells, so that the mechanical strength and the structural rigidity of the deck are greatly enhanced, and the load bearing capacity of the deck is improved. And meanwhile, heat pipes can be pre-buried in the gaps of the lattice structure, and the blanks are filled with low-density and high-heat-conduction materials, so that the heat conduction efficiency is improved while the mechanical property is ensured.

    本发明公开一种卫星用多功能外舱板点阵结构,主要包括内舱板、外舱板、侧壁板、预埋热管、杆状正四面体点阵结构和抗剪切承载杆,内舱板上安装卫星单机,外舱板与真空环境直接接触,充当散热板。所述的预埋热管均安装在内舱板内表面上,预埋热管管翅面紧贴内舱板内表面,增大接触面积,提高换热效率。所述的杆状正四面体点阵结构,外观整体呈正四面体结构,单胞结构类似于金刚石单晶体。本发明采用杆状正四面体点阵结构,点阵单胞内部支臂间形成多个稳定的三角形结构,大幅增强了舱板的机械强度和结构刚度,提高了舱板承载载荷的能力。同时在点阵结构间隙内可预埋热管,空白处填充低密度、高导热材料,在保证力学性能的同时,兼顾提高了导热效率。
