The invention discloses a cabin plate integrally formed based on 3D printing, and relates to the technical field of aerospace. The cabin plate is integrally printed and formed by a 3D printer, a truss channel heat pipe is printed in the cabin plate, and an internal channel is printed in the truss channel heat pipe; a dot matrix structure is printed outside the cabin plate, and a mounting interface for mounting electronic equipment is printed on the dot matrix structure; and the internal channel is used for allowing a heat exchange working medium to flow so that the heat exchange working medium exchanges heat with the electronic equipment. The cabin plate is suitable for load heat dissipation of a space satellite, the situation that in the prior art, a honeycomb core in the cabin plate is damaged through pre-buried heat pipes is avoided, and therefore the cabin plate has better bearing capacity and mechanical resistance, and the purpose of light weight is achieved. In addition, the purposes of heat dissipation and temperature equalization of a plurality of heat sources in all directions can be achieved, the problems of local thermal resistance or heat pipe drying and failure caused by non-connection of the channels are reduced, and the heat dissipation efficiency and the temperature control precision are improved.

    本发明公开了一种基于3D打印一体成型的舱板,涉及航空航天技术领域。该舱板由3D打印机一体打印成型,舱板内部打印有桁架槽道热管,桁架槽道热管内部打印有内部槽道;舱板外部打印有点阵结构,点阵结构上打印有用于安装电子设备的安装接口;内部槽道用于供热交换工质流动,使热交换工质与电子设备进行热交换。本发明公开的舱板适用于空间卫星的载荷散热,避免现有技术中通过预埋热管破坏舱板内部蜂窝芯的情况,从而使舱板具有更优的承载能力和抗力学性能,达到轻量化目的。此外,可以达到多个热源在各个方向的散热和均温的目的,减小由于槽道不连通产生的局部热阻或热管烧干并失效问题,提高了散热效率及控温精度。
