摘　　要：以R134 a为流动工质,设计并建造了流动沸腾传热实验台,从原理设计到调试运行作了详细介绍,并探讨了用材与焊接、密封与保温、特殊加工与制作以及附件布置等环节的流体与机械相关技术问题。该实验台可作为两相流动和沸腾传热特性以及流体模化技术实验研究平台。A flow boiling heat transfer experiment platform was designed and built using alternative refrigerant R134a as. the working fluid. It can be used for investigation on two-phase flow and boiling heat transfer characteristics and fluid-to-fluid modeling of critical heat flux. Some problems concerning the materials, welding, sealing, thermal insulation, special machining and accessories are discussed in detail.
