The invention provides a spacecraft efficient temperature equalization-heat diffusion-heat storage integrated plate and an additive manufacturing method thereof. The spacecraft efficient temperature equalization-heat diffusion-heat storage integrated plate comprises a gas-liquid phase change chamber and a solid-liquid phase change chamber, and the gas-liquid phase change chamber and the solid-liquid phase change chamber are arranged in an up-down adjacent mode; a cone frustum configuration capillary suction structure is arranged on the inner wall of the gas-liquid phase change chamber, and a uniparted hyperboloid configuration bearing column is further arranged in the gas-liquid phase change chamber; a heat conduction enhancing framework is arranged in the solid-liquid phase change cavity and comprises a three-dimensional lattice network structure. Compared with the prior art, larger capillary driving force and smaller flow resistance can be provided, the gas-liquid phase change heat transfer efficiency is improved, three-dimensional heat expansion and temperature equalization of a high-heat-flow device are achieved, and the problems that an original thermal control system formed by gluing a heat expansion block of a high-power device mounting plate, a heat pipe and other assemblies is large in weight and low in efficiency, and a channel heat pipe can only conduct heat in a one-dimensional mode in the axial direction are solved. And the requirements of high-efficiency temperature equalization and heat expansion of a new-generation spacecraft high-heat-flux area array distributed device are met.
