The invention provides an astronavigation branch channel heat pipe suitable for multi-heat-source temperature equalization, the heat pipe comprises a shell, channels and a supporting column, the shell comprises a connecting section and branch sections, the multiple branch sections communicate with the connecting section, and the connecting section and the multiple branch sections are connected with different heat sources; the channels are formed in the inner side wall of the shell, the channels comprise a side channel, a top channel and a bottom channel, the side channel is arranged along the side contour line of the shell to form a communication loop communicated with all the branch sections, and any branch section is communicated with the connecting section through the top channel and the bottom channel. Working medium conveying channels among multiple heat sources are established through the annular through channels in the inner wall of the heat pipe, efficient heat transfer among multiple branches of the heat pipe can be achieved, and therefore temperature equalization of the multiple heat sources is achieved; the heat sources are connected through the independent branches, so that the temperature equalizing speed is high, and the temperature equalizing temperature difference is small; the structure is compact, the weight is light, and temperature equalization of multiple heat sources in a small space can be achieved.

    本发明提供了一种适用于多热源均温的宇航分支槽道热管,热管包括:壳体、槽道以及支撑柱,壳体包括连接段和分支段,多个分支段分别与连接段连通,连接段、多个分支段分别与不同热源连接;槽道设置在壳体的内侧壁上,槽道包括侧面槽道、顶面槽道以及底面槽道,侧面槽道沿壳体的侧面轮廓线设置,形成有连通所有分支段的连通回路,任一分支段均通过顶面槽道、底面槽道与连接段连通。本发明通过热管内壁环形贯通的槽道建立多热源间的工质输运通道,可实现热管多个分支间的高效传热,从而实现多热源的均温;通过独立分支连接各个热源,因此均温速度快,均温温差小;结构紧凑,重量轻,能够实现小空间内多个热源的均温。
