摘要
Abstract
The distribution of heat source inside spacecraft is becoming increasingly complex,and traditional heat pipes can not effectively solve the problem of uniform temperature of multiple heat sources in small space.An axially grooved heat pipe with branches is designed,which establi-shes a heat transfer channel between multiple heat sources through the connection of branches to achieve uniform temperature.The results of the temperature uniform test indicate that when four heat sources with power of 4W,8W,12W and 16W are subjected to uniform temperature,the maximum temperature difference of the branched axially grooved heat pipe is 0.9℃.The results of heat transfer characteristics test show that when heating power is 16W,the thermal resistances between branch and the connecting section,and between the branch and branch are 0.15K/W and 0.17K/W respectively.The temperature uniform and heat transfer characteristics of branched axially grooved heat pipe are qualified,providing a new method for multi heat source temperature uniform.关键词
