本文以乙二醇 水溶液及加入微量添加剂 (表面活性剂 )为工质 ,进行池式沸腾传热试验。试验结果表明 ,十二烷基硫酸钠等表面活性物质对乙二醇 水溶液的沸腾传热有明显的强化作用。在此基础上 ,本文分析了表面活性物质强化乙二醇 水溶液沸腾传热的原因 In this paper, ethylene glycol aqueous solution and adding trace additives (surfactant) as working fluid, the pool boiling heat transfer test. The experimental results show that surfactant such as sodium dodecyl sulfate has a significant enhancement on the boiling heat transfer of ethylene glycol aqueous solution. On this basis, this paper analyzes the reason why surface active substances enhance the boiling heat transfer of ethylene glycol aqueous solution
