摘要
应用重力热管是解决青藏铁路建设中冻土路基冻融问题的一个较为实际的方法。本文通过分析重力热管的热阻网络，提出了重力热管的传热模型。并利用现有的热管内部传热的经验关系式，对不同倾角、不同管径以及不同冷凝管长度条件下的传热量进行模拟计算。
Gravitate heat pipe is one of the optional ways to solve the freezing and thawing of permafrost in the built ofQinghai-Xizang Railway roadbed.The model of heat transfer is put forward through analyzing thermal resistance network ofgravitate heat pipe.Calculations on quantity of heat transfer are performed under the conditions of different inclined angles,pipe diameter and condensation section length,using functions in existence on heat transfer of heat pipe.
