摘要
中温热管在热风炉前置炉中具有很大的应用潜力。采用实验的方法,研究分析了中温萘热管的热工特性,由实验结果可知,采用传统工艺生产制作中温萘热管,可以保证热管工作的基本要求,且热管充液量在90%～100%为最佳。同时,在现场操作时,要特别注意对蒸发段壁温的监测,最好将壁温控制在萘的临界温度(478℃)以下,以确保中温萘热管的安全使用,以免引起爆炸事故。
In hot air furnace,the application of the moderate-temperature heat pipe has great potential.The thermal characteristics of the moderate-temperature naphthalene heat pipe were studied with experimental method.The experimental results showed that the moderate-temperature naphthalene heat pipe produced by traditional craft could also meet the basic requirements of heat pipes,and the optimal filling volume is between 90% and 100%.Meanwhile,in the site operation,to ensure the safety of moderate-temperature naphthalene heat pipe,wall temperature is controlled below the critical temperature（478℃） of naphthalene.Lest cause explosion accidents.
