摘　　要：传统上以水为工质的大容器沸腾换热实验台,存在沸腾发展过程不完整、换热规律揭示不充分、实验现象观测不清晰等问题,难以开展大容器沸腾现象的全过程模拟和多工况放热规律研究。针对这些问题,该文以一氟二氯乙烷(R141b)作为沸腾换热工质替代传统的水工质,以新型复合陶瓷高功率密度加热单元替代传统不锈钢管加热试件,以真空玻璃腔体取代传统开口烧杯,以智能化数据采集系统取代传统测量仪表,形成了基于有机工质的新型大容器沸腾综合实验平台,实现了大容器沸腾换热现象的全过程模拟和多工况放热规律研究。The traditional pool boiling heat transfer experimental platform using water as the working fluid has some problems, such as incomplete boiling development process, insufficient disclosure of heat transfer law,unclear observation of experimental phenomena and so on. It is difficult to carry out the whole process simulation of pool boiling phenomenon and the study of heat release law under multiple working conditions. To solve these problems, a new comprehensive experimental platform for pool boiling based on organic working medium is established in this paper. Monofluorodichloroethane(R141b) is used as boiling heat exchange medium to replace the traditional hydraulic medium. The new composite ceramic high power density heating unit is used to heat the test piece instead of the traditional stainless-steel tube. The vacuum glass cavity is used to replace the traditional open beaker, and the intelligent data acquisition system is used to replace the traditional measuring instrument. The whole process simulation of boiling heat transfer in large containers and the study of heat release law under multiple working conditions have been realized on the new experimental platform.
