摘　　要：对微矩形沟槽热管的传热极限进行数学建模,并通过实验讨论分析热管工质物性群数Nl、几何结构群数Ge和重力比数Hg三者对其传热极限的影响作用。研究表明,Qc与Ge和Hg呈近似指数增长变化,而与Nl成线性增长关系。热管运行于较高温度、合理的几何结构和有效利用重力的辅助作用,可明显提高热管的传热能力,同时也证明了该传热极限模型的正确性。The model on maximum heat transport capacity has been established,which is for micro heat pipe with a rectangle-grooved wick structure.And also discuss the impact of the three parameters, which are Nl,Ge and Hg,on the heat transport limits through experimental investigateon.The study has shown that the higher operation temperature,a reasonable geometric structure and effectively use of the gravity supporting,can significantly increase the heat transfer capacity.And it also demonstrated that the model on heat transfer capacity for micro heat pipe is correct.
