本文对功能化金属表面沸腾传热进行了实验研究。目前的研究表明微纳结构表面可有效提升沸腾传热性能,金属表面的强化传热对于大规模高热流密度应用非常重要,例如在核电工业中。通过飞秒激光表面处理技术在金属表面制备了周期性波纹结构,以去离子水为工质,采用池沸腾实验装置,研究了换热系数(HTC)和临界热流(CHF)。通过池沸腾实验研究表明,相对于光滑表面飞秒激光制备的微纳结构表面传热性能均在不同程度得到了有效提升。
In this paper, the experimental study of boiling heat transfer on functionalized metal surfaces is carried out. Current research shows that micro-nano structured surfaces can effectively improve boiling heat transfer performance, and enhanced heat transfer on metal surfaces is very important for large-scale high heat flux applications, such as in the nuclear power industry. A periodic corrugated structure was prepared on the metal surface by using femtosecond laser surface treatment technology. Deionized water was used as the working medium. A pool boiling experimental device was used to study the heat transfer coefficient (HTC) and critical heat flow (CHF). The results of pool boiling experiments show that the heat transfer performance of micro-nano structures on the smooth surface of femtosecond lasers has been effectively improved for varying degrees.
