摘要
针对回路型振荡流热管,从自激强化(被动强化)传热的角度出发,通过实验对比分析,分别研究了热管采用非均匀截面结构、管内工质为Cu-H_2O纳米流体以及热管采用不等径结构时的强化传热特性.实验研究结果表明:采用上述三种强化传热的方法,在特定条件下,都分别不同程度地起到了强化传热的效果,为振荡流热管强化传热的进一步研究奠定了基础。
The experiment aimed at the self-exciting mode enhanced heat transfer characteristics of looped Oscillating-Flow Heat Pipe(OFHP), compared the different heat pipe with the non-uniform sectional area, Cu-H2O nanometer fluid and non-uniform structure. The experiment indicated that the three methods respectively enhanced heat transfer under a certain conduction, the result established a firm basis for advanced study on enhancement heat transfer of the oscillating-flow heat pipe.
