Integrated three-dimensional heat pipe network heat dissipation device

The utility model relates to the field of thermal control of spacecrafts, and particularly discloses an integrated three-dimensional heat pipe network heat dissipation device which is used for heat dissipation of a spacecraft outboard assembly with an integrally enveloped shell structure and high-heat-consumption equipment in a shell in a dispersed layout. The heat dissipation device comprises a heat collection heat pipe installed on the outer side of the high-heat-consumption equipment; the heat row radiating pipe is installed on the surface of the assembly shell, and the heat expansion plate is connected with the heat collecting pipe and the heat row radiating pipe. And good heat dissipation can be carried out on an existing large space mechanical arm joint. 本申请涉及航天器热控制领域，具体公开了一种集成型三维热管网络散热装置，用于具有整体包络的外壳结构、壳体内部高热耗设备分散布局的航天器舱外组件散热，散热装置包括安装在高热耗设备外侧的热量收集热管，安装在组件外壳表面的热量排散热管，连接热量收集热管和排散热管的扩热板。能够对现有大型空间机械臂关节进行良好散热。
