【摘要】 本文讨论了以萘作为中温热管的工质的性质及其传热能力问题。实验表明:在工作温度为150～478.5℃范围内,即使与碳钢管壳配用,也可确保萘与碳钢具有良好的相容性和安全性,工质不会变劣或分解。根据实验条件,萘热管的传热率介于4.24～10.61W/cm~2之间。本文还讨论了萘热管的应用前景,如果合理设计萘热管换热器,可望在低于700℃的烟气温度下使用。更多还原

【Abstract】 This paper discusses the problem of nature and heat trasfer performance of naphthalene that acts as the working fluid of medium temperature heat pipe, Experiments show that although naphthalene is utilized with pipe wall of carbon-steel in the range of 150℃～478.5℃ working temperature, which can ensure good compatibility and safety between it and carbon-steel. Working fluid can not be got destroying and analyzed. According as experiment condition, heat trasfer rate is in 4.24～10.61W/cm~2. We also discuss problem of applied foreground of naphthalene heat pipe. If we can properly design exchanger of naphthalene heat pipe, then it maybe will be utilized at not more than 700℃ temperature.更多还原
