【摘要】 由于碳钢-水热管工质与管壳材料间的不相容,导致热管冷凝段上部积聚不凝性气体,严重影响了热管的传热性能及使用寿命。本文根据理论分析及试验结果,阐述了不凝性气体产生的因素,提出了解决碳钢-水热管相容性问题的工艺方案,为碳钢-水热管的推广应用提供了可靠的理论及实验依据。更多还原

【Abstract】 Because the working fluid with tube material of the carbon steel-water heat pipe are not compatible, the noncondensable gas is generated and accumulated on the top of condenser section in the heat pipe. Therefore,the gas affects the heat transfer seriouly and also the life-span of the carbon steel-water heat pipe considerably. , Based on the chemical analysis and experimental results,this paper expounds the cause of noncondensable gas generated and presents the method of solving the compatibility problem of the carbon steel-water heat pipe, which gives a theoratre and experimental basis for a wide application of the carbon steel-water heat pipe.更多还原
